Problems solved by technology

[0003] Water conservancy improvement measures usually use irrigation and salt washing to wash out the soluble saline and alkali in the surface soil from top to bottom, thereby reducing the salinity; however, this requires the establishment of a large drainage and irrigation system, which requires a lot of manpower and material resources, and the cost is relatively high. high
[0004] Biological improvement measures mainly improve soil properties by planting saline-alkali-tolerant plants. However, coastal wetlands have high salt con

Abstract

The invention relates to a compound improved conditioner for saline-alkali soil and a preparation method of the compound improved conditioner. The compound improved conditioner comprises the following raw material components: 30-50 parts of an organic conditioner, 40-70 parts of an inorganic conditioner, 10-30 parts of biological conditioner and 5-15 parts of an artificially synthesized conditioner. The preparation method comprises the steps of drying the raw material components until the moisture contents are 4%-8%, grinding the raw material components to be 200-350 meshes, uniformly mixing, adding the mixture into a granulator, and granulating to obtain a finished product. According to the compound improved conditioner, the physical and chemical properties of soil can be improved, the permeability and the moisture and fertility preservation performance of soil can be improved, the ion exchange ratio and the buffer pH value of soil can be increased, the number and the activities of microorganisms in soil can be increased, the soil fertility can be increased, the output and the quality of crops can be increased, the soil improvement effect can be improved, and the soil improvement period can be shortened.

Description

technical field [0001] The invention relates to the technical field of saline-alkali soil improvement, in particular to a saline-alkali soil compound improvement conditioner and a preparation method thereof. Background technique [0002] The content of nitrogen, phosphorus and organic matter in coastal saline-alkali soil is low, the soil is barren, the soil salinization is extremely serious, the primary productivity is low, the vegetation coverage is low, and the soil system has poor ability to fix carbon, nitrogen and phosphorus. It has seriously affected the ecological service function of coastal wetlands as a barrier for efficient resource utilization and environmental protection. The reason why the coastal saline-alkali soil has low yield is mainly because it contains too much soluble salt, and the soil colloid absorbs more sodium ions, which deteriorates the physical, chemical and biological properties of the soil and endangers the growth and development of crops.
