Technical regulations for rapid growth and high yield cultivation of Tamarix chinensis
1 Scope
This standard stipulates the fast-growing and high-yield indicators of Tamarix chinensis and the techniques of construction, management, pest control, and wicker harvesting.
This standard applies to the construction of the national willow forest.
2 Fast-growing high-yield indicators and calculation methods
2.1 Production
The output is shown in Table 1.

2.2 Calculation method
Planting area of 5hm2 or more, random sampling according to 1种植 of planting area, set 2m×2m sample square for picking, weighing, using sample
The average annual production is calculated by unit area yield; the number of sample squares is appropriately increased below 5hm2.
Output per unit area (kg/hm2) = average square bar weight × 2500.
3 Construction technology
3.1 Strip selection
3.1.1 Variety selection
The Yellow River Basin is suitable for planting thin willow, yellow willow, red willow and purple willow; the Huaihe River Basin is suitable for planting thin willow, purple willow, red willow, yellow willow, blue willow and white willow;
The river basin is suitable for planting white willow, red willow, green willow and thin willow.
3.1.2 Standards
Choose medium-lower branches with strong growth, full axillary buds, uniform thickness, and moderate internodes (5cm to 10cm).
3.2 Afforestation site selection
The Yellow River Basin, the Huaihe River Basin, and some of the Yangtze River Basin are flat or shoal, loam or sandy loam, soil pH 5.5~
8.0. The planting area should be of a certain scale and relatively concentrated.
3.3 Site preparation
Deeply turn 25cm ~ 30cm, after leveling, make a bed (or 畦) with a width of 2.5m ~ 3m, the length can be suitable for the ground.
