High-yield cultivation method for Chinese yams

Abstract

The invention discloses a high-yield cultivation method for Chinese yams. The method comprises the following steps that 1, seeds are selected, wherein the Chinese yams which are full in block terminalbud, smooth, slender and free of pest and disease damage and scar and has the stems with the thickness being 2 cm or above are selected, and the upper ends of 16-20 cm are cut out to serve as the Chinese yam seeds; 2, the seeds are dried in the sun, wherein the Chinese yam seeds obtained after disinfection are placed in the sun for drying; 3, a Chinese yam field is selected, wherein the field which is flat, high and dry in terrain, deep and fertile in soil layer, loose, air permeable and smooth in drainage and has the soil being sandy soil or sandy loam is selected as the Chinese yam field; 4, base fertilizer is applied, wherein 100 kg of bio-organic fertilizer, 50-80 kg of compound fertilizer of potassium sulfate (18-18-18), 25-30 kg of urea, 30-50 parts of potassium sulfate and 30-50 kgof nitric acid diamine are applied to the Chinese yam field per mu; 5, sowing is conducted, wherein the Chinese yam seeds are picked for the last time one day before sowing, when sowing is conducted,the Chinese yams are placed in seed furrows with the row spacing being 25 cm, and it is proper to sow 2,500-2,800 plants per mu; 6, topdressing is conducted, wherein topdressing is conducted in time,and after tubers are full, topdressing is stopped for soil. Accordingly, it is guaranteed that the yield of the Chinese yams is greatly increased, and the economical benefit of farmers is increased.
