Liquid conditioning agent improving soil structure of secondary salinization land

Abstract

The invention discloses a liquid conditioning agent improving a soil structure of a secondary salinization land. The liquid conditioning agent is prepared from the following raw materials in parts by mass: 120 to 180 parts of crop waste pulp, 250 to 400 parts of decomposed excrement, 160 to 200 parts of nano carbon, 120 to 160 parts of scenedesmus obliquus decomposition agent, 80 to 120 parts of tealeaf residues, 30 to 60 parts of EDTA-Zn, 8 to 20 parts of azotobacter chroococcum, 800 to 1200 parts of water and 10 to 14 parts of microorganism fermenting agent. The liquid conditioning agent can reduce the salt content of soil, the pH value of the soil and the volume weight of the soil, can effectively increase permeable holes of the soil, can improve the water retaining capacity of the soil, can increase the content of microorganisms in the soil, and can greatly and comprehensively improve the fertility of the soil; and after the liquid conditioning agent is used, the soil fertility is improved, the immunity of crops of agriculture and forestry can be improved, the grain yield is increased, and the energy-saving, environment-friendly and sustainable development trend can be accorded with.

Description

Technical field [0001] The invention relates to a liquid conditioner, in particular to a liquid conditioner for improving the soil structure of secondary saline-alkali soils. Background technique [0002] Saline-alkaline soil is the general term for saline soil, alkaline soil, and various salinized and alkalized soils. Saline soil refers to the soil that contains a certain level of soluble salt in the soil, which can cause obvious harm to the growth and development of plants. Alkaline soil refers to the soil that contains a large number of exchangeable ions, the amount of which can harm the growth and development of plants, and changes the nature of the soil. In actual conditions, saline soil and alkaline soil often coexist in a mixed manner, collectively referred to as saline-alkaline soil. [0003] Soil secondary salinization is also called "secondary salinization", which refers to the process of turning good farmland into "salinization" due to unreasonable human cultivation an...

Problems solved by technology

In addition, if the soil is too alkaline, it will affect the availability of nutrients such as phosphorus, iron, manganese, boron, and zinc in the soil, and will easily cause a large amount of nitrogen, phosphorus, and potassium major elements, as well as trace elements such as iron, calcium, and boron.

[0005] At present, most of the fertilizers used in saline-alkali land are ordinary liquid fertilizers. Although ordinary liquid fertilizers can provide some nutrients for the soil, they cannot effectively increase soil air permeability while reducing soil salinity, soil pH, and soil bulk density. , improve soil water retention capacity, increase soil microbial content, and comprehensively improve soil fertility
