Virus-free seed potato culture system

Abstract

The invention provides a virus-free seed potato culture system, comprising tissue culture vessels and a seed bed. Each tissue culture vessel comprises a vessel body and top cap; a partition is arranged in the vessel body, a culture assembly is placed inside the partition, a fixing piece is arranged at the top of the culture assembly, and a tissue culture hole is formed in the center of the fixingpiece. The seed bed comprises a planting plate, support posts are arranged under the planting plate and are inserted in sleeves, and height of the support posts are regulated through regulating screws; a water trough sleeves the sleeves and its height is regulated through regulating screws; a spray pipe is placed in the water trough, and light-shade cloth is arranged at the edge of the planting plate. Tissue culture and field planting are combined through the detachable tissue culture assembly; the seed bed which is liftable realizes integration of aeroponics and hydroponics, particularly, aeroponics can be adopted to promote growth of plants in growth period of planting stocks, while hydroponics can be adopted in tuber swelling period to reduce tuber water content and avoid osmosis injury.

Description

technical field [0001] The invention belongs to the field of agricultural technology application, and in particular relates to a set of virus-free seed potato cultivation device and cultivation method. Background technique [0002] Potato (Solanum tuberosum L.) belongs to the Solanaceae tuber crop, which originated in the Andes and has high economic value. Humans have domesticated and grown potatoes for more than 8,000 years. Statistics from the World Food and Agriculture Organization (FAO) show that the global planting area and annual output of potatoes are second only to corn, wheat and rice, and belong to the fourth largest food crop. More than 2 / 3 of the countries in the world grow potatoes, and the planting area has continued to increase in recent years. The food and nutrition of residents in many poor areas mainly come from potatoes. Potatoes are also an ideal food, rich in starch, protein, vitamin C, B vitamins, minerals, β-carotene, organic acids and other nutrient...

AI Technical Summary

Problems solved by technology

[0003] There are at least the following problems in the existing virus-free potato seed production: First, the seedling transplanting process is cumbersome. In traditional seedling transplanting, the tissue culture seedlings and the culture medium in the culture bottle need to be placed in the colonization environment for several days, and then washed one by one with water. The culture medium on the root of the tissue culture seedling, and then use tweezers to colonize the tissue culture seedling into the colonization hole one by one

Second, if it is a s...
