4 Production Technology
4.1 Crop Rotation
The crop rotation method should be determined according to different crops in different places. Generally, the previous crop should be a row crop. 4.2 Soil Conditions
Loose, medium-fertility soil is preferred. 4.3 Variety Selection
4.3.1 Seed Selection Principles
Select high-quality, high-yield, strong stress resistance and good commercial varieties according to local conditions. 4.3.2 Seed Quality Standards
Seed purity ≥97%, cleanliness 98%, germination rate 90%, moisture ≥12%. 4.4 Land preparation and cultivation
Plow the land early and at an appropriate depth of about 25cm. Finely prepare the land, loosen the soil, and appropriately thicken the soil layer according to the nature of the soil. In places with more rain in spring and summer, it is advisable to dig ditches and cultivate the land to ensure smooth drainage and irrigation. 4.5 Application of basal fertilizer
4.5.1 Fertilization principles
According to NYT496. Organic fertilizer should be used as the main fertilizer, combined with inorganic fertilizer. Industrial waste, urban garbage and sludge should not be used. Organic fertilizers that have not been fermented and decomposed, have not reached the harmless index and have excessive heavy metals should not be used. 4.5.2 Fertilizer quantity
Combined with land preparation, apply basal fertilizer, and the amount of basal fertilizer should account for more than 70% of the total fertilizer amount. Generally, the amount of basal fertilizer per 667m2 is about 1000kg of organic fertilizer, 8kg of urea, 20kg of superphosphate, and 15kg of potassium chloride. 4.6 Seeding
NY/T5208-2004
4.6.1 Seed treatment
Pea seeds that have passed the germination test need to be selected on the basis of screening and winnowing, and diseased seeds, insect frog seeds, small seeds, loquat seeds, broken seeds, seeds of different colors and mixed seeds should be selected. Then it is advisable to dry the seeds for 8h to 16h before sowing. Sow them after soaking and germination treatment, or sow them directly in the side rows according to local habits. In the case of excessive autumn rain or severe early autumn, germination should not be carried out. 4.6.2 Sowing period
Autumn pea standing areas are generally sown in October and November. Spring pea standing areas are sown from late February to early April. On the premise that the seedlings are not affected by frost, it is recommended to sow them early in time.
4.6.3 Sowing method and sowing amount
The sowing methods mainly include row sowing, spot sowing or broadcast sowing. The sowing amount should be determined according to the size of pea seeds, planting method, planting density and germination rate. The general sowing amount is 15kg-25kg per 667m2. The sowing amount in the spring sowing area should be slightly more, and the sowing amount in the autumn sowing area should be slightly less; the sowing amount of dwarf early-maturing varieties should be slightly more, and the sowing amount of tall stem late-maturing varieties should be slightly less: the sowing amount of row sowing and broadcast sowing is more, and the sowing amount of spot sowing is less: large-grained varieties or high sowing density, the sowing amount is more; small-grained varieties or low sowing density, the sowing amount is less. 4.6.4 Planting density
Generally, high-stem varieties with good soil quality should be planted slightly sparsely: otherwise, it should be planted slightly densely: the general planting density of vegetable peas is 80,000 to 120,000 plants per 667m2: the general planting density of thousand peas is 30,000 to 50,000 plants per 667m2. 4.7 Field ManagementbZxz.net
4.7.1 Thinning
After the seedlings emerge from the soil, the missing seedlings should be filled in time to promote the full seedlings. The methods of filling are divided into replanting and replanting. Among them, soaking seeds to germinate and sowing is the best way to replant. If there are too many seedlings or too dense, it is advisable to thin out the seedlings as soon as possible to promote the growth of seedlings. 4.7.2 Intertillage and Weeding
Pea seedlings are susceptible to weeds and need to be intertilled and weeded 2 to 3 times. Generally, the first intertillage is carried out when the seedling height is 5cm~7cm; the second intertillage is carried out when the seedling height is 10cm-15cm, and soil is added; the third intertillage should be flexibly controlled according to the growth and weeds of peas. 4.7.3 Frame
When the height of creeping peas is more than 30cm, use small bamboo poles or other branches to build frames. 4.7.4 Topdressing and irrigation
In the case of thin soil, insufficient base fertilizer, thin and weak seedlings, and pale yellow leaves, it is advisable to apply topdressing. The fertilization principle shall be implemented in accordance with NY/T496. Topdressing should be carried out when the seedling height is 17cm~20cm. Generally, the amount of fertilizer applied is 2000kg/667m2 of decomposed human and animal feces and urine to water. It is not advisable to apply nitrogen fertilizer for the first period. If the soil dries up early after sowing, it is advisable to irrigate in time. During the growth period, attention should also be paid to irrigation to keep the soil moist. More water is required during the flowering and fruiting period, and attention should be paid to irrigation. In the rainy season, attention should be paid to drainage and waterlogging. 5 Disease and insect control
5.1 Prevention and control principles
The principle of "prevention first, comprehensive prevention and control" should be adhered to. Agricultural control, biological control, physical control should be used first, and chemical control should be used scientifically. When using chemical pesticides, GB4286 and GBT8321 (all parts) should be implemented. It is forbidden to use highly toxic, extremely toxic, and high-line pesticides and their mixed pesticides that are banned by the state. Rationally mix, rotate, and alternate pesticides to prevent and delay the generation and development of pest and disease resistance.
5.2 Prevention and control methods
5.2.1 Agricultural prevention and control
Select high-quality varieties resistant to () diseases: Reasonable layout, crop rotation, strengthen intertillage and weeding, reduce the number of pest and disease sources: cultivate strong seedlings without pests and diseases; sow at the right time to avoid the peak period of pests and diseases. 5.2.2 Biological control
Protect and use natural enemies such as insects to kill aphids and other pests: 2
5.2.3 Physical control
NY/T5208--2004
According to the biological characteristics of the pests, use methods such as sweet and sour liquid, black light or begging lamps to lure and kill the adults of aphids and other pests. 5.2.4 Chemical control
5.2, 4, Sclerotinia, brown spot, downy mildew, damping-off can be used per 667m in the early stage of the disease. 80g of 72% benzene frost, phosphorus manganese zinc wettable powder and 50kg of water can be used for spraying to prevent and control sclerotinia, brown spot, downy mildew, damping-off. It can be controlled once or twice according to the condition. 5.2.4.2 Rust and powdery mildew
At the early stage of the disease, 15% triadimefon wettable powder or 15% diniconazole wettable powder 100g can be used per 667m2 to spray for rust and powdery mildew. Depending on the condition, control can be carried out once or twice. 5.243 Insects, pea weevils, leaf miners
Use 24.5% green mites EC 50mL to 50kg water per 667m2 to spray for leaf miners: In the early or full flowering period, use 24.5% green mites EC 50mL to 50kg water per 667m2 to spray for pea weevils: Use 30g of 3% acetamiprid wettable powder or 30g of 10% aphid mites wettable powder or 50mL of 24.5% green mites EC to 50kg water per 667m2 to spray for aphids. Depending on the condition, prevention and treatment can be carried out once or twice.
6 Harvest
Harvest in time according to market demand and growth period. 7 Establish production files
