Chinese yam continuous cropping resisting cultivation technology

The invention relates to a Chinese yam continuous cropping resisting cultivation technology, and belongs to the technical field of crop production. The Chinese yam continuous cropping resisting cultivation technology includes: when vines completely climb a whole frame after Chinese yam is planted, spraying 50wt% carbendazim wetting powder; in the middle growth stage, spraying 80wt% mancozeb wetting powder on leaf surfaces, spraying the 80wt% mancozeb wetting powder every other 15d, and spraying the 80wt% mancozeb wetting powder for 3-4 times; in the full blooming stage, spraying a mixture of the 80wt% mancozeb wetting powder and amino acid soluble fertilizer on the leaf surfaces, spraying the mixture every other 7d, and spraying the mixture twice; in the later stage, spraying 90wt% mancozeb wetting powder, spraying the 90wt% mancozeb wetting powder every other 15d, and spraying the 90wt% mancozeb wetting powder once or twice. The Chinese yam continuous cropping resisting cultivation technology sprays pesticides according to specific time, specific sequence and specific concentration, greatly reduces occurrence rate of insect damage to Chinese yam, remarkably reduces disease occurrence of the Chinese yam, improves yield and quality of the Chinese yam, and solves the defect that crop rotation is needed when the Chinese yam is planted in the prior art. The Chinese yam continuous cropping resisting cultivation technology further improves continuous cropping resisting ability of the Chinese yam by changing a seed soaking and soil disinfecting method.
