Virus-free potato primary stock culture medium

Abstract

The invention relates to a virus-free potato primary stock culture medium, which is characterized in that the medium is formed by coarse sand, cow dung, modified furfural residue, mushroom residue and sawdust in a mixing and fermenting way according to air-dried volume ratio of 0.25-0.35:0.05-0.15:0.15-0.25:0.15-0.25:0.15-0.25. Since agricultural organic solid waste is used, the invention has the advantages that not only the recycling and the value adding of resources are promoted but also the production cost of virus-free potato primary stock is effectively reduced.

Description

technical field [0001] The invention relates to the field of production of the original seed of the virus-free potato, in particular to a cultivation substrate of the original seed of the virus-free potato. Background technique [0002] Potato (scientific name: Solanum tuberosum, English: Potato), a perennial herb, but cultivated as an annual or twice a year. Underground tubers are round, egg, oval, etc., with bud eyes, skin red, yellow, white or purple; ground stems are prismatic, hairy; odd pinnate compound leaves; cymes terminal, flowers white, red or purple; berries Spherical, green or purple-brown. Seeds reniform, yellow. Multi-purpose tuber propagation. [0003] Potatoes have high nutritional and medicinal value. Modern studies have proved that the starch content of potato seeds is 9-20%, the protein content is 1.5-2.3%, the fat content is 0.1-1.1%, and the crude fiber is 0.6-0.8%. Nutrients contained in 100g potatoes: calories 66~113J, calcium 11~60mg, phosphorus...
