First, select good varieties, suitable for nursery. Spring balsam pear should use high-yield, high-efficiency and high-quality hybrids. Such as: the Guangdong Academy of Agricultural Sciences cultivated Yuefeng No. 1, Green No. 2, emeralds, etc., in the day when the average temperature is stable above 10 °C sowing seedlings. Try to get timely early sowing to extend the period of vegetative growth. Use a nutrition cup (bag) to raise the seedlings, and choose a leeward sunny, near water source, and a convenient management garden to make a seedbed. Pregerminating dew can be ordered on demand, with the root tip down, gently press into the nutrient soil, and set up a 40-50 cm arched bamboo frame, covered with film insulation moisturizing, anti-cold seedlings strong, unfolding film hardening seedlings a week before transplantation. Second, Shizujifei, transplanting appropriate period. Basal fertilizer is generally rotated with 1500 kg of farmyard manure, 25 kg of phosphate fertilizer, and 10 kg of potash fertilizer. The fertilizer is evenly mixed into the hole and then covered with a thin layer of fine soil. Before planting, plant the ground first, then dip the width of the ditch 2 meters wide, plant two rows per plant, spacing 120 centimeters, 40 centimeters from the hole, generally 1100 to 1400 plants per mu, and plant 3 to 4 true leaves at the seedlings. Plant 3 to 5 days of application of light human fecal urine water to "send marriage fat." Third, set up vines, suitable fertilizer. When the seedlings start to pull vines, a herringbone bamboo frame is used. When climbing the vines, the vines should be manually introduced and the vines should be placed on the shelves. After the vines are put on the shelves, the side vines below 40 cm in the stems of the vines will be removed, and the dense leaves and the old leaves will be properly removed. The upper side of the weak side vines, air and light. Topdressing with water and fertilizer is good, so do diligence and thin application, and promote seedlings as soon as possible. After flowering and squashing, it is necessary to top-dress one fertilizer. Generally, 20-25 kilograms of compound fertilizer is used in the mu. In the slicing period, fertilizer should be applied once every 7 days to prolong the harvest period. Fourth, prevention and control of pests and diseases. Chlorothalonil powder can be used 600 times liquid powdery mildew, with 800 times liquid trichlorfon against fruit fly, Spodoptera litura and other pests.
