Jinsi Weeping Willow is a new type of environmental protection tree species, with no flying hair, large annual growth, short nursery cycle, no trunk knots and other characteristics. In autumn, the shoots and trunks gradually turn yellow, and the whole body is yellow in winter. It has a well-developed root system, which is resistant to cold, drought, and salt. Strong disease resistance, quick germination. The cutting propagation can grow to 3-4 meters in height and 2.5 to 3 centimeters in diameter, which is more than three times that of ordinary willow. If autumn is used (in early November), the survival rate can reach 99%, the survival rate of spring insertion is low, and the autumn season is also the best for the afforestation season.
Before the nursery was cut, the soil was rotted and smashed, and the soil was leveled to facilitate irrigation. According to the soil fertility, appropriate amount of base fertilizer, such as decomposed livestock manure, etc., is used and the manure is evenly distributed. The cuttings were cut to a length of 13 to 14 centimeters, spaced 0.25*0.65 meters apart, and planted 3110 acres. After the cuttings were irrigated, the land after watering should be 0.5 cm above the cutting tip.
After cutting out, we need to strengthen management. After the soil is frozen, the soil seam is closed with surface soil. When the soil thawed in early spring, pour frozen water. After budding, wipe the buds when they grow to 10 cm, and select a strong bud. When the new shoot grows to about 30 cm, Mu topdressing urea 20-30 kg. As long as 100 centimeters, 30 to 50 kilograms of Urea urea can be mixed with some quick-acting phosphate fertilizers; Remove the sub shoots 3 to 4 times a year: when it is 80 centimeters long, remove 20-30 centimeters; when it is 150-160 centimeters, remove 50-60 centimeters; grow to 240-270 centimeters. Remove the 120-140 cm tip when centimeters; remove 200-250 cm tip when it is 350 to 400 centimeters long. The tip is cut off from the base with scissors, which facilitates straight growth of the tree.
Timely control of locusts after seedlings, can be used 3000 times imidacloprid; attention at the end of June against bollworm, cypropathrin can be used 1500 times, while adding 2,000 times the broom and net phlegm class.
