Abstract

The invention discloses seedling raising soil for seedling raising of wheat stock seeds in a greenhouse. The seedling raising soil comprises, by weight, 40-80 parts of sandy soil, 15-35 parts of rectorite compound, 15-20 parts of soil conditioner, 30-50 parts of wormcast, 15-35 parts of wheat bran, 15-25 parts of peanut shell powder, 2-8 parts of shrimp shell powder, 1-2 parts of EM microbial agent, 5-15 parts of ammonium nitrate, 10-16 parts of calcium magnesium phosphate fertilizer, 10-18 parts of potash magnesium sulphate fertilizer and 1-4 parts of sodium alginate. The rectorite compound is prepared in the steps that lignin fibers and sodium hydroxide are stirred, filtered and washed to be neutral, rectorite, hydroxyl silicone oil and dimethyl sulfoxide are added and continue to be stirred, filtered and washed to be neutral, hydrochloric acid is added and stirred, tetrabutyl titanate is added for ultrasonic dispersion, heating and standing are conducted, the product is filtered anddried, and the rectorite compound is obtained.

Description

technical field [0001] The invention relates to the technical field of seedling soil, in particular to a seedling soil for raising seedlings in greenhouses of original wheat seeds. Background technique [0002] Wheat is one of the main crops in northern my country. In recent years, with the improvement of people's living standards, the society's demand for high-quality special wheat is increasing, and the planting area of ​​high-quality wheat has increased rapidly. [0003] The original wheat seed is the preferred species for modern wheat planting, suitable for scattered or patched planting in vast areas. Seedling breeding of original wheat seedlings is generally carried out in breeding production bases, and seedlings are raised in greenhouses, which have extremely high requirements for seedling soil. At present, seedling soil has poor water and fertilizer retention, which needs to be solved urgently. Contents of the invention [0004] Based on the technical problems exis...
