Chives are cool and cool. Summer growth falls, quality is poor, and yield is low. In order to increase the output and improve the quality, the Institute of Vegetable Research of Xinghua City, through years of research, has concluded a set of techniques for the cultivation of chives over the summer, which can produce more than 2000 kilograms per mu. Soil preparation sites with good drainage and irrigation conditions should be selected. Chives should not be used as continuous crops. It is best to plant crops with leguminous or cruciferous crops. After the harvest, plowing tillage and drying, after 1 week, 2000 to 2500 kilograms of organic fertilizer per acre, 25 kilograms of special organic fertilizer for vegetables, and 1.5 to 2 meters in width and 20 to 30 centimeters in width. 15-20 cm deep. Seedlings with thick stems and strong root system (3 or more fibrous roots) are transplanted into the seedlings of strong seedlings. They are transplanted from May to July, and the spacing is 13 to 15 cm. The plant spacing is 12 to 13 cm, and 2 to 3 plants per hole are planted. 2.5 to 3 centimeters, after pouring water, live trees. Moisturizing cooling before transplanting a layer of thin rice straw; conditional can cover the shade net. It is also possible to shade crops such as corn on the inside of the scallion field, control the density at 200 plants per acre, or plant the fragrant onions in rows of narrow and narrow rows of semi-high stalk crops such as ginger. Fertilizer management After the live tree, thin manure or 5 kg of urea per acre is used to promote manure. Fertilizer should be applied lightly and frequently, usually 12 to 15 days, 1 time, each application of urea 5 to 8 kg, potassium chloride 4 to 5 kg, combined with fertilization and watering. 15 to 20 days before harvest, 15 to 20 kg of urea per acre was applied, and appropriate amounts of biochemical preparations such as Zhuang Sanqiu and amino acid fertilizers were sprayed. Diseases and diseases of weeds include downy mildew, purple spot, rust, and soft rot. They are controlled by chlorothalonil, metalaxyl zinc, triadimefon, and streptomycin. Insect pests include Spodoptera litura, cotton bollworm, thrips, thrips, and leaf miners, which can be used for prevention and control, such as digging, stuck grams, etc.; for the control of mantle, with the use of water to irrigate root; control plutonium, 90% per acre before transplanting Crystal trichlorfon 1.5 to 2 kg mixed with fine soil application. Before transplanting, it was sealed with soil water of 33% of Shida with 125 ml per mu; during the growth period, if there were more grasses, it could be sprayed with weed grass or fine oil in the period of 2 to 4 leaves of weeds.
