Causes and Prevention of Potato degradation
(1) the reason for potato degradation is that potatoes are planted in spring in hot summer areas in the south. After a year or several years, the yield gradually decreases, or even there is no harvest at all. This phenomenon is called potato degradation. The direct external cause of potato degradation is virus damage. Mosaic virus, mosaic virus, common mosaic virus and hammer tuber virus are common in southern China. These viruses infect plants and cause degradation through vectors such as mechanical friction, aphids, leafhoppers or soil nematodes. High temperature is the indirect external cause of potato degradation.

Causes and Control methods of Hybrid degradation of the latest Wheat varieties
Hybrid degradation of wheat varieties is a kind of wheat that often appears after many times of planting of good wheat varieties. after hybrid degradation, the seed purity of wheat is lower, the quality becomes worse, the stress resistance decreases, and the yield decreases obviously. Then the wheat quality is mixed and degraded.

What is the character degradation of Gastrodia elata? The performance of hemp character degradation is that the yield of arrow hemp decreases, the individual becomes smaller and slender; the yield of rice flax and white hemp decreases greatly, ginger or light brown, the stress resistance is poor, and the original yield and characters can not be fully reflected. The reasons are generally as follows: 1. Multigenerational asexual reproduction.

How to prevent degradation of edible fungi strains
Strain degeneration will lead to slow growth of mycelium, weak resistance to environment, miscellaneous bacteria, etc., fruit body formation period ahead or behind, fruiting tide is not obvious and so on. There are many reasons for strain degeneration, among which impure strain and gene mutation are the main reasons. In addition, high temperature and mixed cultivation of different strains will cause strain degeneration. Measures to prevent strain degeneration include: ensuring pure culture of strains, paying attention not to use strains contaminated by miscellaneous bacteria, not to connect and culture in close proximity; strictly controlling the passage times of strains, reducing mechanical damage,

The crux of the difficulty of plastic film recovery lies in "film".
After more than 30 years of development and application, plastic film mulching has become one of the most important agronomic technologies in China, and even formed a situation that agricultural production can not be carried out without plastic film mulching in Northwest China. At present, on the one hand, plastic film mulching has been incorporated into national and local agriculture.
