3.1.3 Variety and rootstock selection
3.1.3.1 Basis for variety selection
NY/T 5015—2002
Based on the citrus ecological zoning indicators, select excellent varieties in the most suitable and suitable areas to develop pollution-free citrus production. Pay special attention to selecting varieties with strong disease resistance and stress resistance.
3.1.3.2 Commonly used rootstocks
Rootstocks suitable for citrus include: Ji, red orange, Jicheng, Jiyou, Xiangcheng, Toucheng, red orange, Zhuju, Suanyou, Suancheng, etc. For saline-alkali soil and calcareous purple soil, Xiangcheng, Goutoucheng, etc. should be selected. Varieties (lines) infected with cracked bark disease and broken leaf disease cannot use Ji and Jicheng as rootstocks. 3.2 Planting
3.2.1 Seedling quality
Should comply with the relevant provisions of GB/T9659. It is recommended to plant virus-free container seedlings, large seedlings and strong seedlings. 3.2.2 Planting time
Generally, planting is done after the autumn shoots mature in September to October or before the spring shoots sprout in February to March. It is advisable to plant in spring in places with frost damage in winter, and in the dry and hot valley area in the rainy season of May to June. Container seedlings or transplanting with soil are not restricted by seasons. 3.2.3 Planting density
According to the number of permanent plants planted per 667m2, the number of sweet oranges is generally 40 to 60, with a spacing of 3m×4m to 5m; the number of broad-skinned oranges is 60 to 70, with a spacing of 3m×3.5m; the number of grapefruits is 20 to 40, with a spacing of 4m~5m×5m to 6m. For plants used as rootstocks, the planting density can be appropriately increased.
3.2.4 Planting technology
The planting hole is 60cm long, 40cm wide, and 30cm~40cm deep. After the roots and branches of the seedlings are properly trimmed, they are placed in the center of the hole, the roots are stretched, and the soil is straightened. While filling the soil, the seedlings are gently lifted up and tamped down to make the roots close to the soil. After filling the soil, a tree tray with a diameter of 1m is made around the seedlings, and sufficient rooting water is poured. The planting depth should be 5cm to 10cm above the ground. 3.3 Soil, fertilizer and water management
3.3.1 Soil management
3.3.1.1 Deep plowing and expanding the hole, and maturing the soil
Deep plowing and expanding the hole is generally carried out after the autumn shoots stop growing, starting from the drip line outside the crown, and expanding outward by 0.4m to 0.5m year by year. When backfilling, mix with green manure, straw or decomposed human and animal feces, compost, fertilizer, cake fertilizer, etc., put the topsoil on the bottom layer, the heart soil on the surface layer, and then fill the hole with enough water.
3.3.1.2 Intercropping or grassing
It is recommended to implement grassing in citrus orchards. The intercrops or grasses planted should be non-symbiotic with citrus diseases and insects, shallow roots, and short stems. Leguminosae and Gramineae forage grasses are preferred. Cut and turn them over in time and bury them in the soil or cover the tree tray or use them as feed. 3.3.1.3 Covering and cultivation
In hot or dry seasons, it is recommended to cover the tree tray with straw, etc., with a thickness of 10cm-15cm. The covering material should be kept about 10cm away from the rhizome. Cultivation should be carried out after intertillage and loosening the soil in winter. It can be cultivated with non-polluted or harmlessly treated pond mud, river mud, sandy soil or fertile soil near the citrus orchard, with a thickness of 8cm-10cm.
3.3.1.4 Intertillage
If intertillage is required, it can be carried out in summer, autumn and after fruit picking, 1-2 times a year to keep the soil loose. The depth of intertillage is 8cm-15cm, deeper for sloped land and shallower for flat land. Intertillage is not suitable in rainy season. 3. 3.2 Fertilization
3.3.2.1 Principles of fertilization
Follow the provisions of NY/T496-2002. The needs of citrus for various nutrients should be fully met. It is recommended to apply more organic fertilizers, apply inorganic fertilizers reasonably, and advocate leaf nutrition diagnosis formula fertilization. The fertilizers applied should be registered or exempted from registration by the agricultural administrative department. The use of chlorine-containing fertilizers is restricted.
3.3.2.2 Types of fertilizers
Including organic fertilizers, microbial fertilizers, chemical fertilizers and foliar fertilizers. 3.3.2.3 Fertilization methods
NY/T 5015--2002
3.3.2.3.1 Soil fertilization
Can be applied by ring ditch application, strip ditch application and other methods. Dig a ditch (hole) at the drip line of the crown with a depth of 20cm to 40cm. Fertilize symmetrically in the east-west and north-south positions. Citrus orchards with micro-spraying and drip irrigation facilities can be irrigated and fertilized. 3.3.2.3.2 Foliar topdressing
Different types of fertilizers should be used for foliar topdressing at different growth and development stages. Boron, zinc and manganese fertilizers should be sprayed mainly during the spring shoot growth and flowering periods, and supplementary fertilizers should be used at other periods. During the high temperature and drought period, the lower limit of the concentration range should be used, and foliar topdressing should be stopped within 20 days before fruit harvesting. 3.3.2.4 Fertilization of young trees
Nitrogen fertilizers should be used as the main fertilizer, and phosphorus and potassium fertilizers should be applied in combination, in small amounts and multiple times. Fertilize 4 to 6 times during the spring, summer and autumn shoot growth periods, and add foliar topdressing from the time the top buds are cut to before the new shoots turn green. In areas with frost damage, nitrogen fertilizers should be stopped after August. For 1- to 3-year-old young trees, 100g to 400g of pure nitrogen should be applied annually, and the ratio of fluorine, phosphorus and potassium should be 1:0.25 to 0.3:0.5. The amount of fertilizer should increase year by year from less to more. 3.3.2.5 Fertilization of Fruit Trees
3.3.2.5.1 Fertilizer Application Amount
Apply 0.6kg to 0.01kg of pure nitrogen for every 100kg of fruit produced.8kg, the ratio of nitrogen, phosphorus and potassium is preferably 1:0.4~0.5:0.8~1.0. 3.3.2.5.2 Fertilization time and technology
Apply sufficient organic fertilizer (basal fertilizer) after fruit picking, with nitrogen application accounting for 20%~40% of the whole year, phosphorus application accounting for 20%~25% of the whole year, and potassium application accounting for 30% of the whole year; pre-flowering (budding) fertilizer is mainly nitrogen and phosphorus, with nitrogen application accounting for 20% of the whole year; phosphorus application accounts for 40%~45% of the whole year, and potassium application accounts for 20% of the whole year; stable (strong) fruit fertilizer is mainly nitrogen and potassium, with phosphorus fertilizer applied in combination, nitrogen application accounting for 40%~60% of the whole year, phosphorus application accounting for 35% of the whole year, and potassium application accounting for 50% of the whole year. 3.3.3 Water management
3.3.3.1 Irrigation
Irrigation water is required to be pollution-free and the water quality should meet the requirements of NY5016. Citrus trees are sensitive to water during the spring shoot sprouting and flowering period (March to May) and the fruit expansion period (July to October). If drought occurs during this period, irrigation should be carried out in time.
3.3.3.2 Drainage
Timely dredge and dredge the drainage and irrigation system. Drain water in a timely manner through ditches during rainy seasons or when water accumulates in the orchard. In rainy areas before fruit harvest, the soil in the orchard can also be covered with mulch to reduce soil moisture content and improve fruit quality. 3.4 Shaping and pruning
3.4.1 Shaping principles
According to local conditions, pruning according to trees and varieties can achieve the purpose of ventilation and light transmission, three-dimensional fruiting, labor saving and efficiency improvement. 3.4.2 Suitable tree shape
Suitable tree shape changes include trunk shape, natural open heart shape, and multi-branch radial shape. 3.4.3 Pruning points
3.4.3.1 Young tree period
Light pruning is the main method. After selecting the central trunk extension branches and the main branches and secondary main branches, perform moderate to severe pruning on them, and adjust the growth balance between the main branches by the degree of pruning and the direction of the cut buds. Prune the remaining branches lightly to avoid excessive thinning and severe pruning. In addition to appropriate thinning of overcrowded branches, the inner branches and the weaker branches in the middle and lower parts of the crown should generally be retained. 3.4.3.2 Initial fruiting period
Continue to select and prune the extension branches of the backbone branches at all levels, remove the summer shoots, and promote strong autumn shoots. For the overlong vegetative branches, leave 8 to 10 leaves in time to pinch the top, and shrink or prune the branches after fruiting. When there are many summer and autumn shoots, the three-three system can be used: that is, prune one-third of the stronger ones, thin out one-third of the weak ones, and retain one-third of the moderate ones. In autumn, ring cutting, root cutting, water control and other flowering promotion measures are adopted for vigorous trees.
3.4.3.3 Fruiting period
Timely prune back fruiting branches, fallen flower and fruit branches, and declining branches. Prune dead branches, diseased and insect-infested branches. Thin out crowded trunk branches appropriately to create a "skylight" to bring light into the inner part of the tree crown. For the summer and autumn nutrient branches that emerged in the current year, adjust the yield of the next year by pruning some of them or using the three-three system to prevent alternate bearing. When the amount of flowers is large, thin out the flowers or fruits appropriately. For leafless branches, on the basis of heavy thinning, prune most or all of the branches.
3.5 Flower and Fruit Management
3.5.1 Flower and Fruit Control
3.5.1.1 Flower Control
3.5.1.1.1 Flower Suppression: Winter pruning is mainly based on short cutting and retraction; re-pruning before flowering, leaving more flowers on strong branches, fewer or no flowers on weak branches, more single flowers with leaves, fewer or no flowers without leaves; remove deformed flowers, diseased and insect-infested flowers, etc. 3.5.1.1.2 Flower Promotion: In autumn, measures such as ring cutting, root cutting, branch pulling, water control or application of flower promoters can be adopted to promote the differentiation of flower buds of young and vigorous trees. 3.5.1.2 Fruit Control
3.5.1.2.1 Flower and Fruit Protection: Appropriately remove spring shoot nutrient branches, spray flower and fruit protection agents and boron fertilizers during the flowering period and young fruit period. 3.5.1.2.2 Artificial fruit thinning is recommended. The first thinning of fruit is after the first physiological fruit drop, and only small fruits, diseased and insect-infested fruits, deformed fruits, and dense and weak fruits are thinned; the second thinning of fruit is after the second physiological fruit drop, and the fruit and vegetable are thinned according to the leaf-to-fruit ratio. The appropriate leaf-to-fruit ratio is: navel orange 50-60:1, ordinary sweet orange 40-50:1, early-maturing Wenzhou mandarin 30-35:1, mid-late-maturing Wenzhou mandarin 20-25:1, tangerine 60-70:1, and grapefruit 200-300:1. The leaf-to-fruit ratio of weak trees is moderately increased.
3.5.2 Fruit bagging
Fruit bagging is recommended. The appropriate period for bagging is late June to mid-July (after the physiological fruit drop). Before bagging, the citrus orchard should be sprayed once or twice according to the occurrence of local pests and diseases. After spraying, select normal and healthy fruits for bagging in time. Paper bags should be windproof and rainproof, and have good air permeability. Single-layer bags are preferred. Bags should be removed about 15 days before fruit harvest. 3.6 Application of plant growth regulators
3.6.1 Principles of use
Limited use of plant growth regulators that can improve tree growth, increase fruit yield, improve quality, and are harmless to the environment and human health is allowed.
3.6.2 Allowed plant growth regulators and technical requirements3.6.2.1 The main types are benzyl adenine, 6-benzyladenine, gibberellins, ethephon, chlormequat, etc. 3.6.2.2 Technical requirements

3.7.1 Principles of Control
Actively implement the plant protection policy of "prevention first, integrated control". Based on agricultural and physical control, with biological control as the core, scientifically use chemical control technology according to the occurrence law and economic threshold of diseases and pests, and effectively control the damage of diseases and pests. 3.7.2 Plant Quarantine
It is prohibited to transmit quarantine diseases and pests from epidemic areas to protected areas. The protected areas shall not transport seedlings, scions, fruits and seeds from epidemic areas, and they shall be destroyed immediately once discovered.
3.7.3 Agricultural Control
3.7.3.1 Planting shelterbelts: follow the provisions of 3.1.2. 3.7.3.2 Select disease-resistant varieties and rootstocks: follow the provisions of 3.1.3. 3.7.3.3 Intercropping and grass cultivation in the garden: follow the provisions of 3.3.1.2. 3.7.3.4 Implement agricultural measures such as tilling, pruning, cleaning the orchard, drainage, and shoot control to reduce pest and disease sources, strengthen cultivation management, enhance tree vigor, and improve the tree's own resistance to pests and diseases. Improve the quality of fruit picking, reduce fruit wounds, and reduce the fruit rot rate. 3.7.4 Physical and mechanical control
3.7.4.1 Use light to control pests
Light can be used to lure or repel fruit moths, beetles, leaf rollers, etc. 3.7.4.2 Use chemotaxis to control pests
NY/T 5015—2002
Pests such as the large fruit fly and the pseudo-small yellow leaf roller have a tendency to sugar, wine, and vinegar. This characteristic can be used to add pesticides to sugar, wine, and vinegar to lure and kill them. 3.7.4.3 Use color to control pests
Yellow boards can be used to lure and kill aphids.
3.7.4.4 Artificial capture of pests, centralized planting of intermediate hosts to lure and kill pests Artificial capture of longhorn beetles, cicadas, beetles and other pests; artificial planting of intermediate hosts in areas where fruit-sucking armyworms are seriously infested, luring adults to lay eggs, and then using pesticides to kill larvae.
3.7.5 Biological control
3.7.5.1 Artificial migration and breeding and release of natural enemies It is recommended to use the nissius mite to control mites; use the Japanese square-headed beetle and the Hubei red-spotted ladybird to control the arrow-pointed aphid; use the pine caterpillar trichogrammatid to control the leaf roller, etc.
3.7.5.2 Application of biological pesticides and mineral-based pesticides It is recommended to use biological pesticides such as Bacillus thuringiensis and bitter·smoke water agent and mineral-based pesticides such as copper oxychloride, copper hydroxide, and mineral oil emulsion. 3.7.5.3 Use of sex attractants
Place sex attractants and a small amount of pesticides in the field to kill male citrus fruit flies and reduce the chance of mating with females. 3.7.6 Ecological control
Follow the provisions of 3.1.2 and 3.3.1.2.
3.7.7 Chemical control
3.7.7.1 Selection of pesticide types
3.7.7.1.1 Highly toxic and highly residual pesticides that must not be used are listed in Appendix A. 3.7.7.1.2 The use of pesticides for control should comply with the requirements of GB4285 and GB/T8321 (all parts). The types of commonly used pesticides are listed in Appendix B. This table will be revised with the registration of new pesticide varieties. 3.7.7.2 Use of pesticides
For the control of major insect pests, it is recommended to apply pesticides at appropriate times. Disease prevention and control should be carried out at the early stage of the disease. During the prevention and control period, the safe interval, application amount and application frequency should be strictly controlled. Attention should be paid to the alternating use and reasonable mixing of pesticides with different action mechanisms to avoid the development of pesticide resistance. See Appendix C. 3.8 Fruit Harvest
Fresh fruit is harvested when it matures normally and shows the inherent quality characteristics of the variety (color, aroma, flavor and taste, etc.). Storage fruit should be harvested 7 to 10 days earlier than fresh fruit. Use round-headed fruit shears to harvest the fruit, requiring two cuts per fruit, and the fruit stems to be even. 55
