Hardened soil conditioner prepared from crop straw

Abstract

The invention discloses a hardened soil conditioner prepared from crop straw and relates to the technical field of straw processing. The conditioner is prepared from raw materials in parts by weight as follows: 150-200 parts of the crop straw, 20-25 parts of alfalfa, 10-15 parts of bagasse, 10-15 parts of corncobs, 8-12 parts of spent grains, 8-12 parts of sawdust, 6-10 parts of leaves of illicium anisatum, 6-10 parts of camellia sinensis, 5-8 parts of oil bran, 5-8 parts of peanut shells, 4-6 parts of fly ash, 3-5 parts of activated clay, 3-5 parts of rice bran wax, 3-5 parts of carboxymethyl chitosan, 2-4 parts of Chinaberry leaves, 2-4 parts of tea seed powder, 2-4 parts of hydroxyapatite, 1-2 parts of kudzurvine toot powder, 1-2 parts of castor seed powder and 0.5-1 part of chili seed powder. With the adoption of the conditioner, the problem of hardening of soil can be effectively relieved, the soil can be loosened, the fertility of the soil can be improved, aerobic respiration of roots of crops can be promoted, absorption and utilization of mineral ions are facilitated, meanwhile, the problem of pollution of the soil can be solved, and healthy growth of the crops can be promoted.

Description

Technical field: [0001] The invention relates to the technical field of straw processing, in particular to a compacted soil conditioner prepared by using crop straw. Background technique: [0002] In recent years, crop stalks have become a new source of air pollution in rural areas. Every year during the summer harvest and autumn and winter, a large amount of wheat, corn and other stalks are burned in the fields, producing a large amount of thick smog, which not only becomes a bottleneck for rural environmental protection, but even becomes a disaster and the culprit in the urban environment. [0003] Soil compaction refers to the lack of organic matter and poor structure of the soil surface layer. At present, although the commercially available soil conditioners can improve soil compaction, they will change the physical and chemical properties of the soil, which is not conducive to the growth of crops or reduces the fertility of fertilizers. In view of the above situation,...
