It is a new cultivation mode that Jiangan County has succeeded in planting new winter soybeans. It is suitable for the promotion of planting in the main producing areas with an altitude of 400 meters below sea level and rich in light and heat resources. The technology has the advantages of increasing multiple cropping index, fertility, comprehensive efficiency, strong operability, high land use efficiency, and coordinated population growth. It has been planted in Shibu Village of Tonglu Town and has been planted with an average income of 80-150 tons per mu. Yuan, its cultivation points are as follows: 1. Variety: Gaochun selected the local high-quality variety Shuiyinghong, winter soybeans selected upright “Gongxuan No. 1†and red earthworm selected “Chuanshu 27â€, “Suai†and Other varieties. Xiaochun crops were selected for early maturing varieties. Second, the planting period: sorghum in mid-March, late sowing planted in mid-May transplanting, soaking with warm water before sowing 6 to 8 hours, 50 grams per square foot seedbed sowing, cover about 1 cm sow fine soil, or splash Heavy pig feces cover species, and then cover the film insulation. Winter soybeans were planted in mid-May and red leeks were planted before and after awnings. Third, planting density: sorghum line width and width of cultivation, wide line 2.8 feet, narrow line l.2 feet, nesting 1 foot, double planting, acres planted 6000 strains. Soybeans are sowed on the spot while planting sorghum, and are placed in the middle of a narrow row of tall stilts. The nesting distance is 1.5 ft., which is a specification of 4x1.5 ft., with 1,000 litters per acre and 2-3 seeds per litter. In the wide line, Hung Hom planted two rows of plants from the high lands, planted ridges and planted them on the high hills, and planted 3,000 acres. Fourth, fertilization technology: The main organic fertilizer, chemical nitrogen supplement, add phosphorus and potassium fertilizer. Sorghum Mu with defecation water 20 to 30 tons, plus ammonium bicarbonate 30 to 45 kg, calcium magnesium phosphate fertilizer 25 to 40 kg, potash appropriate amount of nest, after transplanting three weeks and then use urea 5 kg plus defecation water to raise seedlings, pull Look at the seedlings as appropriate before the holiday. Soybeans were planted with grass and ash mixed with fertilizer, and during the grain period, potassium dihydrogen phosphate was used for extra-root dressing. Red locust transplanted with defecation water plus ammonium phosphate rinsing nest, potato block swelling period 1 to 2 times. V. Field management: It is mainly drought prevention and drainage, pest control, and removal of weeds. The main diseases of sorghum are sheath blight, smut, carbon sickness, downy mildew, etc. It can be controlled by jinggangmycin, kasugamycin, etc. The main pests are locusts, soil larvae, corncob, corn borer, etc. Chrysanthemum pesticides can be used for control. Soybean seedlings prevent and control silkworms, and in the later stages they use omethoate and other insecticides to control aphids, leafhoppers, pods, and pods.
