High-quality cultivation techniques for horseshoe
First, choose a different species. The horseshoe that is used for breeding should be dug before the Spring Festival. The shape should be flat, round and straight. The skin is smooth, the skin color is red and brown, and the buds are stout. The diameter of 16-18 grams of fruit is used as a kind of pod. After 2-3 years of horseshoe cultivation, the species is degraded and the resistance to disease is reduced. Second, nursery transplanting. The stalk blight of horseshoe is mainly caused by a species of scorpion bacillus, which can be sterilized by 50% carbendazim 600 times solution + 70% thiophanate-methyl 800 times solution or 12.5% ​​riliquid solution 1500-2000 times solution 18-20 Hours, then raise seedlings, bulb spacing 5-6 cm, drench thin manure to keep the soil moist, 2-3 days before transplanting, remove the obvious sick and weak seedlings, and then spray once 12.5% Prevention of stalk blight, with medicine transplanted. Before the end of July, the planting distance was 50-55 centimeters and 60 centimeters long, and 2000-2500 plants were planted per acre. Before the planting in early August, planting distance was 40-45 centimeters and 50 centimeters, and 3000-3500 plants were planted per acre. Third, strengthen the management of fertilizer and water 1, Shizu base fertilizer. After the rice is harvested, the rice fields are ploughed and the weeds are cleared. Mushi rot 1500-2000 kg of farmyard manure, 30-50 kg of superphosphate, 20 kg of potassium chloride, 15 kg of urea, or 30-40 kg of 15-15-15 compound fertilizer 2-3 kg of borax and zinc sulfate were used as the base fertilizer. After the fertilization, the second ploughshare was used and the seedlings were planted 3-4 days later. Top-dressing fertilizers are mainly quick-impact fertilizers, which are generally applied 4 times. The first return to green manure, after 5-8 days of planting, 5-8 kg of urea per acre are used for planting; the second time of afforestation, 15-20 days after planting, combined with 15-15-15 sulphuric acid in Mushi in Putian Potassium compound fertilizer 20-25 kg; 3rd ramet fertilizer, about 30 days after planting, combined with the second weeding field, Mushi Shi cattle bark 1000-1250 kg, superphosphate 25-30 kg, 15 -15-15 potassium sulfate compound fertilizer 25 kg; the fourth time to recover manure, in the middle of October about 15-15-15 acres of potassium sulfate compound fertilizer 40-50 kg, 40-50 kg of peanut bread, potassium sulfate 15-20 kg. 2, the application of hormones and foliar fertilizer. Apply 25-3010-6ABT rooting powder No. 5 solution (ie, 0.1 g rooting powder dissolved in alcohol to 4 kg water) rooting. Before the end of September, the ABT rooting powder (0.4g) + paclobutrazol (100g) + rare earth fertilizer (50g) + potassium dihydrogen phosphate (200-300g) was sprayed on 50-60kg of water. 3, scientific management of water. After planting, the field should be kept in a shallow water layer to facilitate the seedlings to turn green; shallow 4-5 cm of water should be poured during the tiller ramets period to promote the growth of the tillers, and 12 cm or more of deep water should be poured after the line is sealed to prevent the occurrence of tiller ramets; Drainage to maintain a shallow layer, in order to facilitate stem growth down, early formation of bulbs, bulbs during the expansion period to deepen the water to 8-10 cm, mature to keep the field moist.
