Improver for improving enzymatic activity of saline-alkaline soil

Abstract

The invention belongs to the technical field of saline-alkaline soil, and particularly relates to an improver for improving the enzymatic activity of the saline-alkaline soil. The improver comprises the following raw materials in parts by weight: 45-55 parts of a sludge fermentation material, 6-8 parts of sodium nitride, 6-8 parts of microcrystalline wax, 1-3 parts of double-peptide nucleic acid,3-4 parts of sodium tetraborate decahydrate, 3-7 parts of calcium superphosphate, 2-5 parts of acetic acid, 8-12 parts of diatomite, 1-3 parts of CuSO4.7H2O and 2-3 parts of bioactive bacteria. Compared with the prior part, the invention has the following advantages: harmful substances, pathogenic bacteria, and the like in the sludge fermentation material are effectively decomposed; the time spentin fermentation is shortened; harmful ingredients in a fermentation base material are reduced; the pore of the soil is increased; the nutrient source of microorganism in the soil is obtained; the decomposition of the microorganism is facilitated; the pH value of the soil is lowered; the loss of effective constituents is decreased; the content of organic matters in the soil is increased; the content of total salt in the soil is reduced; the growth of plants is promoted.

Description

technical field [0001] The invention belongs to the technical field of saline-alkaline soil, and in particular relates to an improving agent for improving saline-alkaline soil enzyme activity. Background technique [0002] Soil is the loose surface layer on which plants can grow on the earth. Fertility is the basic condition of soil. There are many basic shapes that affect soil fertility. Now the main researches are the thickness of soil tillage layer, texture and structure of tillage soil, soil organic matter content, soil Nitrogen, phosphorus, potassium and other nutrient content, the area of ​​saline-alkali soil is large, its use value is high, and it has a great impact on agriculture and the ecological environment. Under the influence of salinity, the soil solution directly poisons the crop cells, and the poor growth of the crops causes seedling shortage, yield reduction, and death. How to improve saline-alkali soil has been studied in the prior art. In the prior art, t...

[0002] Soil is the loose surface layer on which plants can grow on the earth. Fertility is the basic condition of soil. There are many basic shapes that affect soil fertility. Now the main researches are the thickness of soil tillage layer, texture and structure of tillage soil, soil organic matter content, soil Nitrogen, phosphorus, potassium and other nutrient content, the area of ​​saline-alkali soil is large, its use value is high, and it has a great impact on agriculture and the ecological environment. Under the influence of salinity, the soil solution directly poisons the crop cells, and the poor growth of the crops causes seedling shortage, yield reduction, and death. How to improve saline-alkali soil has been studied in the prior art. In the prior art, the pH value of the soil is changed to increase its organic matter through a reasonable proportion of raw materials, but the improvement effect is poor and needs to be further strengthened; soil enzyme activity is affected by many factors. impact, is related to the overall nutritional status of the soil, and there is no research on the improvement agent for soil enzyme activity improvement in the prior art. Therefore, in the present invention, further research is carried out on the improvement of saline-alkaline soil
