Experts recently reminded that new potatoes produced with virus-free potatoes cannot be used as seed potatoes for the next season. The so-called detoxified potatoes are produced under strict conditions of insect control, contact prevention, and anti-virus sources in greenhouses and field isolation. After stem tip stripping, virus serological detection, and tissue culture, the production of test tube seedlings is similarly strict. Under protective conditions, small potatoes are produced through the substrate or atomized cultivation. This small potato is the true original species of virus-free potato. After the original virus-free potato seed is grown in the above-mentioned field isolation production conditions for one season, the middle-sized potato block is produced as a detoxified potato seed, and then the detoxified potato seed can be expanded to produce farmers' needs. Detoxified potato production species. It can be seen that the research and production of detoxified potatoes are carried out under a series of stringent conditions. The new potato produced from virus-free potato was used as the next season seed potato. Since there was no detoxification, the incidence in the field would increase significantly, the potato block would be deformed, the buds would be darkened, and the yield would be reduced by about 30% compared with the detoxified potato.
