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. Table 1 Planting density growth period Annual output of fresh strips/(kg/hm2) Applicable variety 0.04m×0.4m 1a 42000 2a 50000 3a 54000 Yellow willow, purple willow, red willow 0.06m×0.4m 1a 37000 2a 45000 3a 48000 Qingliu, Bailiu, Huangliu, Hongliu 0.10m×0.3m 1a 46000 2a 55000 3a 60000 Qingliu, Bailiu, Hongliu, Thin willow, purple willow, yellow willow 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.
