1, choose a good land, fine soil preparation. Select the gentle slope of sandy loam soil with loose soil, deep soil, cool back shade, and gentle slope, fine soil preparation, and trenching to prepare for sowing. For continuous land plots, mu shall be spread with 50-100 kg of lime evenly 10 days before sowing and plowed into the soil. Land for three consecutive years must fall. 2, ridging, intercropping interplanting. The konjac was sown with deep sorghum (ridges) and ridged. The ridges were kept at 35 cm or more, and the pods were 40-120 cm wide. The top buds were placed at a 45-degree angle, and the cover soil was 10-15 cm after sowing. When planting, pay attention to "shallow planting, deep planting." At the time of sowing, it was advocated to cover the grass with grass, “grass making grass†and a thickness of 5-10 cm. For plots where daylight shines for more than 8 hours, crops are intercropped, usually using konjac-maize mode, corns selected mid-maturing high pole varieties, growing period of about 130 days, seedlings in late March, transplanting in mid-April, planting spacing 30-40 cm. When transplanted, corn leaves and konjac are in a vertical direction. Corn stalks are processed in time for harvesting at the end of July and early August to provide sufficient light for konjac to grow. 3, selected seed pods, disinfection treatment. Choose the shiny skin, the shape is Zhou Zheng, buds small, flat mouth, top buds thick, smooth surface, no sickness, no injury, no kind of injury. Before sowing, the seedlings shall be air-dried for 2-3 days, combined with drying for disinfection. Method is: 1 per kilogram of medlar with 40% formaldehyde 2ml + potassium permanganate 1g closed fumigation 24 hours; 2 with 72% of agricultural streptomycin 500 times, 53.8% can kill 500 times, alternate spray disinfection 2 -3 times. 4, suitable sowing, reasonable close planting. The suitable sowing date for konjac is from March 20 to April 10, which is slightly late at high altitude and slightly earlier at low altitude. When planting seed pods are sorted and sorted by size. The planting density was 6 times the diameter of the seed pods as the row spacing, and the seed pod diameter was 4 times the plant spacing. 5, scientific fertilization. The general principle of konjac fertilization is based on farmyard manure and supplemented by chemical fertilizers; base fertilizer is mainly based on top dressing, and phosphorus supplementation and nitrogen supplementation are adhered to. The amount of farmyard manure applied is 2500-5000 kg, 40 kg of potassium sulfate compound fertilizer or 40 kg of potassium sulfate compound fertilizer, and 50 kg of ecological organic fertilizer. Gully application, the first ditch to apply organic fertilizer and fertilizer, and then cover the soil cover fertilizer, after the kind of skew be placed on both sides of the fertilization ditch, and finally ridge cover cover species 15-20cm. During the fertilization process, strict separation of fertilizers should be implemented to avoid causing rotten seedlings.
