Soil conditioner and soil improvement method

Abstract

The invention relates to a soil conditioner and a soil improvement method. The soil conditioner is prepared from the following components in parts by mass: 500 to 1000 parts of active calcium, 30 to 100 parts of a soil loosening agent, 200 to 500 parts of fulvic acid, 100 to 300 parts of amino acid and 2 to 10 parts of a medium trace element source. The soil conditioner adopts a specific material ratio, the components cooperate with each other to achieve a synergistic effect, the soil conditioner simultaneously acts in two aspects of improving the soil environment and improving the crop viability, the dosage is small, the effect taking speed is high, the emergence rate and seedling rate of saline-alkali soil crops can be effectively increased, the yield is increased, and therefore the saline-alkali soil ecological environment is promoted to enter a virtuous cycle; and the problem of soil salinization is fundamentally solved.

Description

technical field [0001] The invention relates to the field of agricultural technology, in particular to a soil improving agent and a soil improving method. Background technique [0002] Saline-alkali land refers to the fact that the land is affected by natural or human factors, causing salt substances to gradually penetrate into the soil, thereby increasing the salt and alkali content of the soil, thus forming land that cannot be used any longer. The saline-alkali soil itself contains too much salt, which makes it difficult for plant cells to absorb inorganic nutrients and water in the soil, causing plants to die due to their own lack of inorganic nutrients and water, which not only causes economic losses, but also continues to deteriorate the ecology of saline-alkali land. Form a vicious circle. [0003] Adding saline-alkali soil improver is a simple and efficient important measure to improve saline-alkali land. However, traditional saline-alkali soil improvers generally on...

Problems solved by technology

The saline-alkali soil itself contains too much salt, which makes it difficult for plant cells to absorb inorganic nutrients and water in the soil, causing plants to die due to their own lack of inorganic nutrients and water, which not only causes economic losses, but also continues to deteriorate the ecology of saline-alkali land. form a vicious circle

[0003] Adding saline-alkali soil improver is a simple and efficient important measure to improve saline-alkali land. However, traditional saline-alkali soil improvers generally only focus on reducing soil pH and salinity, and cannot further improve other physical and chemical properties of saline-alkali land. In order to improve the stress resistance of plants in saline-alkali land , so as to improve the viability of plants in saline-alkali land, and then improve the ecology of saline-alkali land, making it enter a virtuous circle

The traditional saline-alkali soil improver treats the symptoms but not the root cause. It needs to be continuously applied to the saline-alkali land to alleviate the salinization of the land. The improvement cycle is long, resulting in high cost of soil improvement, which greatly limits the application of saline-alkali land improver
