The invention provides a siberia elderberry cultivation deratization method. Siberia elderberry seeds are soaked by water for 48 hours, the seeds are soaked by
warm water for 48 hours at the temperature of 55 to 62 DEG C, and the seeds are drained to be sowed.
Sowing adopts autumn spaced
sowing, the line spacing is 55-63cm, the row placing is 9-12cm, two seeds are sowed in each hole, and soil with the thickness of 2.5-3.2cm is covered. Due to the fact that
dormancy stage of the seeds is one year, soil cannot be loosened and
weed cannot be hoed in two years after the seeds are sowed.
Irrigation is performed after seedlings are unearthed in the third year,
irrigation is performed every 13-18 days, and small
water flooding is performed four times in one year. Weeds are hoed between lines and pulled out between rows, and
fertilizer is applied in late May. The seedlings can be transplanted in autumn of the same year,
transplanting can be performed in late October every year when leaves of the seedlings fall and the seedlings stop growth or before shoots
bud in spring in the north, roots of the seedlings need to carry soil balls during
transplanting, and the soil balls are wrapped by gunnysacks.
Transplanting tree wells are 1 / 3 larger than the soil balls, soil is filled back after
transplanting, the seedlings are watered thoroughly and deeply, the soil is tamped, and the space between planted trees is 50 meters so as to achieve deratization effect.
