Embodiment 1

[0017] A method for improving saline-alkali soil by using beneficial microbial bacteria, comprising, the weight ratio of the beneficial microbial bacteria to the mixture of biochar, sphagnum moss, corn cob and coconut bran is 0.5: 45, and the biochar, sphagnum moss, After corncob and coconut bran are mixed in a weight ratio of 1:5:10:10 and crushed through a 100-mesh sieve, add 30% water in mass fraction to obtain the mixture of biochar, peat moss, corncob and coconut bran, which will be beneficial Microbial bacteria are domesticated and inoculated into the mixture of biochar, sphagnum moss, corn cob and coconut bran, piled up in a pile, covered with plastic wrap, and placed in a ventilated room for 6 days. During the period of 6 days, the plastic wrap is uncovered and wetted with sucrose solution every morning. Stir evenly and cover with plastic wrap, the amount of the sucrose solution is 8% of the mixture of biochar, peat moss, corncob and coconut bran, then sprinkle the mixt...

Abstract

The invention discloses a method for improving saline-alkali soil by utilizing beneficial microbial bacteria. The method comprises the following steps: domesticating the beneficial microbial bacteria and inoculating into a mixture of biocarbon, peat moss, maize cobs and coco coir; scattering the mixture of the biocarbon, the peat moss, the maize cobs and the coco coir into soil needing to be improved; then enabling the soil to be subjected to deep ploughing to reach the depth of 20 to 30cm and evenly mixing, then watering the soil to ensure that the moisture content of the soil is not less than 30 percent, and finally covering a fresh-keeping film for 10 to 15 days; uncovering the fresh-keeping film every two days, watering the soil of 100 to 200kg/mu and then ploughing the soil again; finally covering the fresh-keeping film again. According to the method disclosed by the invention, the beneficial microbial bacteria are inoculated into the mixture of the biocarbon, the peat moss, the maize cobs and the coco coir after being domesticated, and the mixture of the biocarbon, the peat moss, the maize cobs and the coco coir is used as an dependent matrix of the beneficial microbial bacteria, so that the activity of the microbial bacteria can be effectively improved, and the quantity of bacterial flora of the beneficial microbial bacteria is increased; moreover, the mixture is scattered into the saline-alkali soil needing to be improved again, so that the activity of the saline-alkali soil can be effectively improved.

Description

technical field [0001] The invention relates to the technical field of soil improvement. More specifically, the present invention relates to a method for improving saline-alkali soil by using beneficial microorganisms. Background technique [0002] Soil improvement is the process of taking corresponding physical, biological or chemical measures to improve soil properties, increase soil fertility, increase crop yield, and improve the soil environment for human survival by taking corresponding physical, biological or chemical measures against the poor texture and structure of the soil. Conditioning agents, soil improvers All materials that are mainly used to improve the physical, chemical and biological properties of soil to make them more suitable for plant growth, rather than mainly providing plant nutrients, are called soil improvers. For example, lime is used to adjust the pH value of acidic soil, and gypsum is used to suppress Na in the soil. + , HCO 3- , and CO 3 2-...
