Problems solved by technology

[0002] With the upgrading of wheat processing enterprises and the continuous modernization of processing technology, the modern wheat processing industry has put forward higher and higher requirements for the quality and stability of wheat. In order to produce wheat with high protein content, farmers in the north use excessive amounts of chemical fertilizers. Not only does it lead to soil compaction, but also the nitrogen utilization rate is low, a large amount of nitrogen fertilizer is lost, and the environment is seriously polluted
[0003] The original wheat seed is the basic seed for breeding and popularizing improved varieties, and has extremely high requirements on the seedling soil. However, the current seedling soil has technical problems of poor water and fertilizer retention, which need to be solved urgently

Abstract

The invention discloses a water and fertility preserving seedling growing soil for wheat breeder's seeds. The seedling growing soil comprises, by weight, 60-100 parts of sandy soil, 30-50 parts of halloysite compound, 110-130 parts of organic fertilizer, 2-4 parts of EM microbial inoculums, 6-10 parts of nano fly ash, 4-10 parts of nano coconut shell carbon powder, 8-16 parts of vermiculite powder, 2-4 parts of mica powder, 4-8 parts of coal gangue, 55-65 parts of major element fertilizer and 3-7 parts of sodium alginate. The halloysite compound is prepared according to the following process that linter and sodium hydroxide are stirred, filtered and washed to be neutral, halloysite, polydimethylsiloxane and dimethyl sulfoxide are added, the mixture continues to be stirred, filtered and washed to be neutral, hydrochloric acid is added and stirred, tetraethoxysilane is added and ultrasonically dispersed, and the product is heated, standing still, filtered and dried to obtain the halloysite compound.
