The following terms and definitions apply to this standard. 3.1
Timber bamboo forest
A bamboo forest that produces and manages bamboo as its main product. 3.2
Site level of bamboo forest
Site conditions are divided into several levels according to their suitability for bamboo growth, which are called bamboo forest site levels. For the classification of bamboo timber forest site levels, please refer to Appendix A. [GB/T20391-2006, definition 2.3]
Standing bamboo age
The survival time of a single standing bamboo, expressed in "degrees". The degree of the new bamboo is 1 degree from the time when the new bamboo grows up to the time when the leaves are replaced in the spring of the second year, and 2 degrees from the time when the leaves are replaced to the time when the second leaves are replaced. After that, the leaves are replaced once every two years, and the degree is increased by 1 degree. The age composition of the standing bamboo is expressed as the percentage of the number of standing bamboos of each age in the unit area of the bamboo forest to the total number of standing bamboos. 3.4
DB33/T959—2014
Bamboo forest with big and small years
A bamboo forest with a large number of bamboo shoots and bamboos in each year is called a big year, and a year with a small number of bamboo shoots and bamboos is called a small year. 3.5
Flower-year bamboo forest
A bamboo forest with a small change in the number of bamboo shoots and bamboos in each year. 3.6
It is composed of the culm base and the culm handle, including the dense bamboo roots that support the bamboo culm and absorb soil nutrients and water. 3.7
Felling in the same direction
Felling method of standing bamboos.
Half-flag felling
For bamboo forests with a slope of more than 25°, dig the soil along the upper part of the slope at the base of the standing bamboos to be felled, split the bamboo flag with an axe, then push the bamboo down the slope, saw off the bamboo near the flag, and restore the flag with soil. 3.9
Manually or with light machinery, fell the weeds and shrubs in the bamboo forest and spread them flat in the forest. 3.10
Bamboo cavity fertilization
After using drilling equipment such as drills and cones to dig holes at the base of the bamboo stalks to the bamboo cavity, use a continuous syringe to inject liquid fertilizer into the bamboo cavity and then seal it.

Cultivation technology
Site condition selection
Select bamboo forests of site level I, site level III, and site level III for timber forest management. 6.2 Stand structure regulation
Retain shoots and cultivate bamboo
Retain shoots and cultivate bamboo throughout the shoot period of bamboo timber forest, according to the principle of retaining large and removing small, retaining sparse and removing dense, retaining strong and removing weak. The number and size of bamboo shoots retained and cultivated are determined according to the bamboo forest structure indicators of different site levels (Table 1), and new bamboos are evenly distributed in the forest. 6.2.2 Felling Price
Except the bamboo shoot period, bamboo can be felled in other seasons, but bamboo should be cut as little as possible during the whipping period and the bamboo shoot differentiation period. Selective felling should be used, and the number of bamboos felled should not exceed the number of new bamboos. Select bamboos with a height of more than 3 degrees, wind-fallen bamboos, diseased and insect-infested bamboos, deformed bamboos, and weak bamboos for felling. The hollow bamboos in the forest should be retained. When felling bamboo, try to use a steel chisel to break through the bamboo cutting area. DB33/T9592014
The bamboo felling methods include flat felling and half-cutting. After felling bamboo, the bamboo tops are placed in the bamboo forest for about a week, and then moved out of the forest after the bamboo leaves dry and fall off naturally.
6.3 Fertilization
6.3.1 Types of Fertilization
The annual one-time fertilization method is adopted. Fertilization methods include ditch fertilization, plant hole fertilization, broadcast fertilization, felling fertilization, and bamboo cavity fertilization. Fertilizer types include bamboo fertilizer, compound fertilizer and bamboo yield increase agent. The quality of compound fertilizer and bamboo fertilizer should meet the requirements of GB15063. 6.3.2 Fertilization time
For bamboo forests with a flowering year and bamboo forests with a double-year and double-year, fertilizer should be applied in May to June when the bamboo shoots are produced, and in bamboo forests with a double-year and double-year, fertilizer should be applied in September to October. 6.3.3 Fertilizer application amount
The annual fertilizer application amount is 100kg/hm2~120kg/hm2 of nitrogen, 20kg/hm2~25kg/hm2 of phosphorus (P0s), and 40kg/hm2~45kg/hm2 of potassium (K,0). Bamboo fertilizer, compound fertilizer, etc. can be used. 6.3.4 Fertilization method
6.3.4.1 Fertilization in trenches
Dig trenches horizontally along the contour lines, 20cm~25cm deep, 20cm wide, and 2m~3m apart, apply fertilizer and cover with soil. 6.3.4.2 Plant hole application
Dig a half-moon-shaped trench 20cm~25cm deep and wide on the upper part of the slope 30cm away from the base of the standing bamboo, apply fertilizer and cover with soil. 6.3.4.3 Broadcasting
By natural precipitation, spread bamboo-specific fertilizer and compound fertilizer in the forest land. 6.3.4.4 Fertilization in felled stumps
In the felled stumps 1 to 3 years after the bamboo was felled, use a steel chisel to drill through the nodes, apply fertilizer, and then cover the felled stumps with soil. 6.3.4.5 Fertilization in Bamboo Cavity
Drill holes with an electric drill 10 cm below the base of the standing bamboo stalks from May to June, and then inject 5 ml to 8 ml of fertilizer solution diluted with bamboo yield enhancer (the ratio of original solution to clean water is 1:5) with a continuous syringe, and then seal the needle hole with yellow bottom soil. 6.4: Splitting the Mountain
Split the mountain once manually or mechanically before the weeds and shrubs are lush and the seeds are immature (July to August), and lay the weeds and shrubs in the forest to fertilize the soil. The density of standing bamboo in the bamboo forest is high, and there are few weeds and shrubs in the forest, so splitting the mountain is generally not done. Chemical herbicides are prohibited. When splitting the mountain to remove weeds and shrubs, narrow crowns or precious tree species in the bamboo forest can be purposefully retained, and then a mixed forest of bamboo needles and broadleaf bamboos with 8 bamboos and 2 trees or 9 bamboos and 1 tree can be established.
6.5 Forest Reclamation
DB33/T959-2014
Reclamation is conducted every 6 to 8 years, with a depth of more than 25 cm. It is conducted after the new bamboo shoots have finished their branches and leaves. The reclamation year for the bamboo forest with biennial growth is selected in the year when bamboo shoots grow and mature. For slopes below 20°, full reclamation is adopted. For slopes above 20°, strip rotation reclamation or block reclamation is adopted. The width and distance of strips are 3m to 5m, and half-cutting of strips can be exempted from reclamation.
6.6 Shoot Harvesting
In the bamboo forest for timber use, only the faded shoots, thin shoots, weak shoots, and overcrowded shoots are dug. Injured shoots are dug in time. Winter shoots and whip shoots are generally not dug, or a small amount of winter shoots are dug.
6.7 Hooking
In areas where snow pressure, ice hanging, windfall and other hazards are serious, hooking of new bamboo shoots is adopted according to local conditions. Hooking of new bamboo shoots is carried out from the autumnal equinox to the light snow season, and the number of branches left is more than 18.
6.8 Bamboo
In autumn and winter, use a special bamboo pen or a marker to write the bamboo planting year on the new bamboo stalks. 6.9 Set up ecological buffer zones
In order to avoid soil erosion and environmental pollution during the management of bamboo forests, a buffer zone with a width of 10m to 15m is set at the bottom of the steep slope, especially for bamboo forests in drinking water source areas. Only mild artificial interference such as forest structure regulation, manual or light mechanical mountain splitting, etc. is implemented to establish mixed forests, and chemical fertilizers and chemical pesticides are not used.
6.10 Understory composite management
Select bamboo timber forests with good site conditions, near water sources, and convenient transportation, and implement understory composite management such as bamboo tea, bamboo medicine, and bamboo fungi. The composite management measures are coordinated with the management measures of bamboo timber forests, and do not interfere with the growth of bamboo. 6.11 Disease and pest control
Disease and pest control in bamboo timber forests should follow the principles of prevention first, legal management, scientific prevention and control, and health promotion. Forecast and early prevention of harmful pests and diseases such as bamboo, bamboo locust, bamboo tussock moth, bamboo egg round bug, and bamboo dieback disease, based on forest management, give priority to biological and physical control measures, and adopt chemical control when necessary. Quarantine pests and diseases to prevent their spread. The use of pesticides for pest control in bamboo forests should comply with the provisions of NY/T1276. See Appendix B for the comprehensive prevention and control methods of major pests and diseases in bamboo timber forests. 7 Bamboo quality grading
