Breeding matching technology for potato breeder's seeds

Abstract

The invention belongs to the technical field of potatoes, and discloses a breeding matching technology for potato breeder's seeds. The technology comprises the following steps: S1, removing viruses in plants by stem tip stripping and heat treatment methods, then cutting off vertexes of growing buds by using a knife, and putting the plants into a culture medium for cultivation. According to the technology, coal cinder and sterile cloth are combined for use, the problem that watering is too much or too little can be solved, water is applied to the surface of a nutrient soil layer, the soft soil layer cannot remain water, the water can permeate the nutrient soil layer and flow into the coal cinder under filtration of the sterile cloth, the phenomena that seedling death occurs and the survival rate of the test-tube plantlets is influenced due to the fact that fragile roots of test-tube plantlets are gradually rotted in the humid nutrient soil with accumulated water for a long time can be avoided, and by means of the sterile cloth, the nutrient soil on the upper layer can be prevented from being lost, and the loss of most nutrient components can be avoided; and as the temperature in a greenhouse is generally high, the water evaporation is fast, and the nutrient soil layer is easy to dry, the good breeding of the potato breeder's seeds is ensured.

Description

technical field [0001] The invention belongs to the technical field of potatoes, and in particular relates to a supporting technology for the original seed breeding of potatoes. Background technique [0002] Potatoes, edible tubers, are one of the most important food crops in the world. The original seed breeding of potatoes is the process of harvesting the original seed after the original seed is planted. Breeding units have higher purity and better quality through the original seed production procedures, while improved varieties are improved on the basis of original seeds, with better quality and yield. For the seed potatoes initially produced by cuttings, the most critical step related to potato yield and quality is the breeding of the original potato species.

Although it reduces the cultivation cost and has wide applicability, the simple soil cultivation cannot provide suffi...

Problems solved by technology

[0003] Traditional potato original seed breeding technology generally adopts soil cultivation. Although it reduces the cultivation cost and has wide applicability, the simple soil cultivation cannot provide sufficient nutrition for the seedlings, and some transplanted seedlings will grow. The phenomenon of dead seedlings appears, thereby reducing the survival rate of test-tube seedlings. In soil cultivation, the soil is loose and ventilated, which affects the growth of seedlings. growth environment, in addition, during the growth of test-tube seedlings, appropriate watering is required and the amount of watering at each stage is different. Existing watering methods cannot control the amount of watering. How easy it is to cause dead roots
