Integrated high propagation method of water planting of virus-free potato seeds and seedlings

Abstract

The invention relates to an integrated high propagation method of water planting of virus-free potato seeds and seedlings. The method comprises the steps that a multiplication technology of the water-planting virus-free seedlings and a water planting production technology of the seedlings and the seeds are integrated, and the concentration of nutrient solution components, the light quality of a supplementary light source, hormone components, seedling cutting times and the like are optimized at the same time. According to the method, the stability and security are high, operation and daily management are simple and convenient, the maintenance and production costs are low, the sound seedling index of water-planting potato plants are significantly improved, the yield and quality of the seedlings and mini-potato are improved, the plant propagation coefficient is enlarged, the production cycle of the mini-potato is shortened, and the method is of great importance in breeding of the potato seeds and seedlings.

Description

technical field [0001] The invention belongs to the technical field of soilless cultivation, and in particular relates to a high-power breeding method for the integration of virus-free seed potatoes and seedlings through hydroponics. Background technique [0002] Potato is a tuber plant of Solanaceae family and is an important food crop in the world. However, the potato will be infected with viruses and degenerate and reduce production after many years of planting, with an average production reduction of 30-50%. At present, the main technology used by scientists all over the world to solve the degradation is to propagate seedlings through virus-free shoot tips, then breed minitubers and further breed the original species for use. Its potato virus-free seed potato breeding methods mainly include matrix cultivation, aeroponic cultivation, hydroponics and test tube cultivation and other methods. Among them, the hydroponic breeding technology of potato virus-free seed potatoes...

AI Technical Summary

Problems solved by technology

Simultaneously, although the existing method can meet the needs of potato hydroponic seed potato production, it cannot provide the best growth environment for stolon, tuber generation and expansion during the production of potato virus-free seed potato

Therefore, it is not conducive to the early occurrence and frequent occurrence of stolons; it is not conducive to the normal expansion of potato tubers; it cannot solve the contradiction between later tuber growth and root system nutrient absorption in the nutrient solution; it cannot reduce or reduce the growth of algae such as green algae; it cannot solve the nutrient solution Too high or too low temperature problem
