Problems solved by technology

At present, in order to promote the rapid growth of agricultural plants and high yields, a large amount of chemical fertilizers or various plant regulators are used in agriculture. The chemical fertilizers are derived from ore metals or carbohydrate synthesis such as diamine phosphate, urea, etc. Although these fertilizers have played a good role in supplying Fertilizer effect, but also severely damaged the aggregate structure of the soil, making the soil compacted

Abstract

The invention discloses a composition capable of prompting forming of a soil granulation structure, which comprises the following components in parts by weight: 1-2 parts of bacillus agent, 20-40 parts of rice bran, 2-5 parts of demerara, 2-5 parts of potassium dihydrogen phosphate, 2-5 parts of copperas, 25-60 parts of live stock manure, and 20-40 parts of straw powder. According to the composition, probiotic bacteria bacillus agent is contained and is in mutualism with flora in the soil; the metabolite generated by the probiotic bacteria and the self product of the thallus can improve the soil granulation structure, so as to free soil and avoid soil hardening. Moreover, with the rice bran, the demerara 4, the potassium dihydrogen phosphate, the copperas, the live stock manure and the straw powder, the reproduction activity of the microbes in the soil is increased, and the survival amount and reproduction activity of earthworms in the soil can also be improved, which in turn improves the soil granulation structure.

Description

technical field [0001] The invention relates to soil improvement technology, in particular to a composition for promoting the formation of soil aggregate structure. Background technique [0002] Soil aggregate structure is a kind of soil structure formed by agglomeration of several soil single grains bonded together. Because small pores are formed between single particles and large pores are formed between aggregates, the total porosity is larger compared with the single particle structure. The small pores can keep water, and the large pores can keep ventilation. The soil with aggregate structure can ensure the good growth of plant roots and is suitable for crop cultivation. The number and size distribution of soil aggregates directly affect the basic symptoms such as soil aeration, water retention, infiltration and soil erodibility, and the distribution of soil aggregates is often used as an important indicator for evaluating soil fertility and soil quality. At present, i...
