Special cultivation matrix for potatoes

Abstract

The invention provides a special cultivation matrix for potatoes which is a cultivation matrix applied to a method for no-tillage potato planting through covering with straws. The special cultivation matrix is prepared from, by weight, 22 parts of humus soil, 6 parts of pine needle mulch, 7.5 parts of corn straw powder, 1.5 parts of compound fertilizer of which the PNK content is 7:7:9, 2 parts of quick lime, 1.5 parts of radix stemonae, 1.2 parts of polygonum cuspidatum, 0.3 parts of ligusticum wallichii, 0.5 parts of schizonepeta, 0.2 parts of saposhnikovia divaricata, 0.5 parts of coptis chinensis, 1.6 parts of carthamus tinctorius, 2.5 parts of liquorice, 1.5 parts of tetrapanax papyriferus, and 1.2 parts of acorus calamus, wherein the pH value is 5.8. The special cultivation matrix for potatoes has the functions of sterilization and insect repelling, can well protect the seed potato buds and prevent the seed potato buds from being damaged by pests in the soil or infected by bacteria, has good air permeability and water retention performance, and can provide necessary nutrition elements for potato seedling germination. By laying a layer of the special cultivation matrix for potatoes in the bed, the problem that the part below the straw layer is easy to mildew after covering with straws can be solved.

Description

technical field [0001] The invention relates to the technical field of potato cultivation, in particular to a method for no-tillage cultivation of potatoes covered with straw and a cultivation substrate used in the method. Background technique [0002] Potatoes are also called ground eggs, potatoes, yams, yam eggs, etc. Potato tubers contain about 2% protein, and the protein content in dried potatoes is 8% to 9%. The nutritional value of potato protein is very high, and its quality is equivalent to that of eggs. It is easy to digest and absorb, and it is better than the protein of other crops. Moreover, potato protein contains 18 kinds of amino acids, including various essential amino acids that cannot be synthesized by the human body. Potatoes are highly evaluated for their nutritional value, and their tubers contain high-grade protein and essential amino acids lysine, tryptophan, histidine, arginine, phenylalanine, valine, leucine, and isoleucine The presence of amino a...

Problems solved by technology

The disadvantage of this cultivation method is that the potatoes form tubers in the soil, and when the tubers expand, they are squeezed by the soil, which is not conducive to the expansion of the tubers. In the case of non-sand
