3, Adopting suitable cultivation measures, such as planting in selected sandy loam, high fertilizer, rational close planting, strengthen field management, timely control aphids, and early harvest, etc. can promote healthy plant growth, enhance the ability of anti-degradation and reduce field virus and prevent degradation. To avoid the storage of tubers affected by high temperature or cryogenic freezing and dehydration shrinkage, premature bud loss of nutrients, pest damage and so on, to prevent the old bad seed, reduced viability, which causing degradation.
