Method for breeding breeder's seeds of potatoes with coconut coir as medium

Abstract

The invention discloses a method for breeding breeder's seeds of potatoes with coconut coir as a medium. The method comprises the following steps of arrangement of cultivation facilities for coconut coir, wherein a net shed, a solar greenhouse and other separation facilities are adopted, an insectproof net of 40 mesh or above is arranged, a seedbed is made and set up, the medium is laid, an irrigation facility is made, and a fertilizer application system is made; daily management after field planting of the seedbed, wherein irrigation, fertilizer application and disease and pest control are conducted, and the culture medium is added; harvesting, wherein 20 days before harvesting, water and fertilization application is stopped, the net shed or solar greenhouse is covered with a waterproof material, and then harvesting can be conducted after the medium is dried; medium disinfection and replacement, wherein the medium is disinfected and replaced before the start of second-season production. By means of the method, the problems are solved that a current culture medium (vermiculite) used for breeding breeder's seeds of potatoes is non-renewable and high in PH value, is easily hardened,and has poor permeability, harmful germs in the medium are hard to eliminate, and the environment is severely contaminated by the culture medium.

Description

technical field [0001] The invention relates to a potato breeding method, in particular to a method for breeding original potato seeds with coconut peat as a substrate. Background technique [0002] Potato is an important grain and vegetable dual-purpose crop in our province, with a planting area of ​​more than 10 million mu. Gansu Province is not only an important commodity potato base in my country, but also an important supply base for seed potatoes at all levels. In 2016, the output of miniature seed potatoes in our province has reached 10 With more than 100 million grains, potatoes have become an important crop for increasing agricultural efficiency and farmers' income in our province. Although the cultivation substrates used in the production of miniature potato seeds in my country are diverse, the substrate used on a large scale and on a large scale is vermiculite, which is a secondary metamorphic mineral of hydroaluminosilicate containing magnesium with a layered ston...

AI Technical Summary

Problems solved by technology

Because the matrix is ​​made of natural ore fired at high temperature, its mining and processing have a huge impact on the natural environment and air quality. There was an event that the vermiculite processing plant was ordered to stop production by the environmental protection department. Scale limitation, which will have extremely serious and even devastating impact on the production of miniature seed potatoes in my country

In addition, the physical structure of vermiculite is destroyed during use, and potato root exudates and pathogenic bacteria accumulate, so vermiculite can only be used once, and its natural quality cannot be returned to the field, and a large amount of waste vermiculite is accumulated
