Virus-free sweet potato and its excellent varieties
Virus-free sweet potato refers to the sweet potato without some virus and its offspring bred in aphid-free and disease-free soil after strict virus detection. At present, virus disease has become an important reason for the degradation of seed performance, yield and quality of sweet potatoes in Henan Province, while virus-free sweet potatoes can generally increase production by more than 30%, and their quality and appearance have also been improved. Therefore, the selection of virus-free sweet potato seedlings is a prerequisite for high yield of sweet potato. Starch processing potato Xushu 18: detoxified

Virus-free technology of potato
Potatoes are nutritious and resistant to storage. It has a short growth period and great potential to increase production, so it is fond of eating for people. However, potatoes are easy to be infected with a variety of viruses, resulting in smaller tubers, deformities, seed potato degradation and so on. The experimental results show that the detoxification of potato by stem tip tissue culture combined with virus detection and the production of virus-free seed potato can effectively prevent the degradation of seed potato and greatly increase the yield of potato. The main detoxification methods are as follows: 1. Take materials and disinfect the tubers of the varieties to be detoxified to sprout. When the buds grow 4~5cm, cut the buds and peel off the outer leaves.

Five attentions to the introduction of Spring Potato
At present, it is the season of potato planting. When adjusting and purchasing seeds, we must know in detail the latitude, altitude and climatic conditions of the producing area of potato stem, and correctly select the producing area and variety according to the law of potato introduction. Specific attention should be paid to the following five aspects: first, latitude and altitude tests show that the introduction from high altitude to low altitude and from high latitude to low latitude is easy to succeed. The reason is that the temperature is lower during the growing period of potato at high altitude and high latitude, the virus infection of potato stem is lighter and the degradation is slow, which leads to planting at low altitude and low latitude, which generally performs better.

Cultivation Techniques of Potato with High Quality, High Yield and High Efficiency in Hilly and Dry Areas
About 85% of potato planting area in our province is mainly distributed in hillside and hilly areas, with cold climate, short frost-free period, sufficient light, large temperature difference between day and night, annual rainfall of only about 400 mm, and mostly concentrated in July and August. Drought, windy and evaporation in spring constitute the ecological environment conditions of drought for ten years and nine years. The unfavorable factors of drought and water shortage seriously hinder the development of agricultural production.

Propagation technique of virus-free test-tube plantlets of potato
Potato is the fifth largest crop in Heilongjiang Province, only after rice, wheat, corn and soybeans. it can be used as food, vegetables, industrial raw materials and other crops. Potato is still a new industry in Heilongjiang Province, with a history of only more than 20 years. The formation and development of this industry is accompanied by the research and development of potato detoxification technology. Through the smooth implementation of the poverty alleviation and development project of "joint construction of courtyards and counties" and under the guidance of experts and professors of the Provincial Academy of Agricultural Sciences, Huachuan County has established Sujiadian Town and Lifeng Township.

Techniques of seed selection and purification and rejuvenation of garlic
Because garlic is asexual reproduction, garlic cloves are abnormal lateral buds and part of garlic mother, long-term asexual reproduction will inevitably lead to the accumulation of virus in the body and the accumulation of other bad characters, resulting in the degradation of garlic species. The degraded garlic plant is short, the photosynthetic capacity is low, the garlic becomes smaller and the quality decreases, which seriously affects the yield and benefit of garlic. In this paper, several key techniques for seed selection, purification and rejuvenation of garlic are introduced as follows: first, to establish garlic fields in different places and to establish garlic fields with certain regional differences and cultivation differences, which can avoid garlic.
