Abstract

The invention relates to the technical field of soil conditioners, in particular to a soil activator. The soil activator consists of the following materials in parts by mass: 30-60 parts of peat humic acid, 2-5 parts of polyvinyl alcohol, 2-5 parts of polyacrylonitrile, 2-6 parts of gypsum powder, 6-12 parts of bentonite, 3-8 parts of perlite, 6-12 parts of bacterial cellulose, 2-8 parts of a soil water-retaining agent, 2.8-5.8 parts of sulfur, 2.8-6.4 parts of a pH buffer agent and 6-12 hundred millions of photosynthetic bacteria groups per kg. A mixture of gluconobacter liquefaciens cellulose and chitosan acetic acid bacterial cellulose is added into the soil activator, so that the soil activator has a high water absorption property and a high water retention property because of the nano effect, and can effectively improve the soil. By adopting the soil activator provided by the invention, the volume weight of the soil reaches 35.2%, the maximum water holding capacity of the soil reaches 38.2%, the water absorption rate of the soil reaches 23.6%, the soil aggregate content reaches 34.2%, and the total N / P / K content in the soil reaches 41.5%.

Description

technical field [0001] The invention relates to the technical field of soil conditioners, in particular to a soil activator. Background technique [0002] Soil is the material basis of agricultural production and the basic resource for ecological environment construction, which is inseparable from human beings. However, due to people's unreasonable development and utilization of soil, soil erosion, desertification, desertification, salinization and soil pollution have caused soil land degradation and soil quality decline. How to effectively improve poor-quality soil and make full use of limited land resources is a major problem that needs to be solved urgently in agricultural production, ecological construction and environmental protection. [0003] The existing soil conditioning products have a single effect, and the method of applying organic fertilizers is mostly used to achieve soil improvement, which cannot fundamentally change the growth environment of crops, resultin...
