Aeroponic virus-free seed potato breeding method and accessory equipment

Abstract

The invention provides an aeroponic virus-free seed potato breeding method and equipment. The breeding method includes the following steps: equipment cleaning and disinfection, greenhouse disinfection through a smoke drug, seedling hardening, planting and atomization, illumination and temperature management, seedling shedding, overgrowth and lodging control, nutrient solution concentration management, nutrient solution pH value management, nutrient solution temperature management, pest and disease damage prevention, and harvesting. The breeding equipment includes cultivation tanks, cultivation plates, a nutrient solution, a solution storage container, a solution delivery pipe, atomization nozzles, a circulating pump, and a nutrient solution return pipe, wherein each cultivation tank is a cuboid tank of which the length is much larger than the width, the inner surface of each cultivation tank is painted black, the outer surface of each cultivation tank is painted silvery grey, and each cultivation tank is supported from the ground through a bracket; the solution storage container is an underground solution storage pool, a temperature sensor is arranged in the solution storage pool, and a nutrient solution cooling thermolator is arranged outside the solution storage pool. The method provided by the invention can reduce the seedling time, prolong the collection period, and increase the yield; the number of stolons is increased, so as to lay a foundation for a higher yield of virus-free seed potatoes. The equipment provided by the invention is convenient to manage, can save energy, and runs reliably.

Description

technical field [0001] The invention belongs to the field of agriculture, and in particular relates to seed potato breeding. Background technique: [0002] The aeroponic production of virus-free potato microtubers is a new technology developed and researched in my country in recent years. It sprays nutrient solution regularly to make the roots of the plants obtain the water and nutrients needed for growth in the dark and without substrate conditions, which not only solves the problem of potato The nutrient conditions required for growth also solve the problem of root oxygen demand. [0003] The existing aerosol cultivation of virus-free seed potatoes is still in the stage of small-scale production or scientific research and exploration experiments in small-scale greenhouses, and has not been applied to large-scale production. In terms of cultivation methods, there is no systematic and strict production management and supporting storage measures. In large-area aerosol-culti...

Problems solved by technology

The three patents are all small-scale scientific research experiments, and have not been applied to large-scale large-scale production

Patent 5 shows that it is relatively simple, and the volume of the cultivation tank is relatively large, and it is inconvenient to operate during production, especially the harvesting of seed potatoes is troublesome.

The breeding equipment of the three patents have common defects: first, the cultivation tank is made of plastic extruded benzene board, which is poor in firmness, sealing and heat conductivity during use; second, self-priming pumps are required for the return of nutrient solution To operate, it is impossible to use the height difference and the invention of the facilities and equipment itself to increase energy consumption; third, the nutrient solution pools are made of plastic buckets or plastic basins, and such devices can only be used in small-area experiments. The solidity of a large amount of nutrient solution is very poor, and the temperature required for potato production is relatively low. This device cannot control the temperature of the nutrient solution in summer production; fourthly, there is no nutrient solution filtering device in the breeding equipment of the 3 patents. Due to the aerosol production and utilization of nozzles, the requirements for impurities in the nutrient solution are very high. If the nutrient solution cannot be filtered effectively, the nozzle will be blocked, which will affect the growth of virus-free seedlings, especially the survival rate of virus-free seedlings at the initial stage of planting.
