Abstract

The invention belongs to the technical field of soil improvement, and particularly relates to a saline-alkali soil conditioner as well as a preparation method and application thereof. The soil conditioner is prepared from the following raw materials in parts by weight: 40 to 80 parts of humic acid, 10 to 30 parts of bacillus natto (CCTCC M 2019025), 10 to 30 parts of bacillus coagulans (CCTCC No. M2019529), 40 to 80 parts of plant leaching residues and 1500 parts of a plant extracting solution. A preparation method of the plant leaching residues and the plant extracting solution comprises the steps that plants are soaked in water for 6-10 h, so that effective substances in the plants are dissolved out, after soaking is finished, filtering is conducted, the collected filtrate is the plant extracting solution, and the collected filter residues are the plant leaching residues. The soil quality of the saline-alkali soil is improved by combining a biological method and a plant method, the content of total salt, the content of water-soluble calcium ions, the content of carbonate ions and the content of sulfate ions in the saline-alkali soil are reduced, the physical and chemical properties of the soil are made to be in a better state, the effect can be achieved within one month, and the time is greatly shortened compared with that of a traditional plant method.

Description

technical field [0001] The invention belongs to the technical field of soil improvement, and particularly relates to a saline-alkali soil conditioner and a preparation method and application thereof. Background technique [0002] Soil salinization in arid areas is the main problem of soil degradation. Due to the lack of annual precipitation in arid areas, and even heavy wind and sand in some areas, the soil is hardened, the plants die, and the green area is greatly reduced. Over time, the ecosystems in these areas are destroyed. Therefore, the ecological problems caused by the saline-alkali land need to be solved urgently. [0003] There have been many studies on the improvement of saline-alkali soils in the prior art. For example, Zhao Xu et al. used tamarisk, fly ash, coal gangue, silt, etc. to improve the soil. and coal gangue have a good promoting effect on the germination, germination and survival rate of switchgrass (References: Zhao Xu, Peng Peihao, Li Jingji.
