Hydrogen-rich liquid biological improvement agent for saline and alkaline land as well as preparation method and application thereof

Abstract

The invention discloses a hydrogen-rich liquid biological improvement agent for a saline and alkaline land as well as a preparation method and application thereof. The hydrogen-rich liquid biologicalimprovement agent is prepared from the following raw materials in parts by weight: a solvent and hydrogen element which is dissolved into the solvent, wherein the saturation degree of hydrogen in thesolvent is 0.1 to 100%; the solvent is supplied by running water or irrigation water. The preparation method comprises the following steps of S1, firstly, preparing hydrogen gas, mixing the hydrogen gas and the solvent by a jet device, sending into a static mixer through a water pump, and finally forming the hydrogen-rich liquid biological improvement agent for the saline and alkaline land througha nanometer releasing device; S2, application of the hydrogen-rich liquid biological improvement agent for the saline and alkaline land: directly conveying the hydrogen-rich liquid biological improvement agent for the saline and alkaline land to the plant roots via pipelines in ways of agricultural drip irrigation, permeation irrigation and the like. The hydrogen-rich liquid biological improvement agent for the saline and alkaline land has the advantages that the cost is low, the stability is high, the pollution is avoided, the residue is avoided, and the environment-friendly effect is realized.

Description

technical field [0001] The invention relates to the technical field of saline-alkali land improvement, in particular to a hydrogen-rich liquid saline-alkali soil bio-improvement agent and its preparation method and application. Background technique [0002] Saline-alkali soil is a general term for saline soil and alkaline soil. Saline soil mainly refers to salinized soil with high chloride or sulfate content. The soil is alkaline, but the pH value is not necessarily high. Alkaline soil refers to the soil containing carbonate or heavy phosphate, the pH value is high, the soil is alkaline, the organic matter content of saline-alkali soil is small, the soil fertility is low, the physical and chemical properties are poor, and there are many anions and cations harmful to crops. Promote seedlings. The principle of fertilization in saline-alkali soil is mainly to apply organic fertilizers and high-efficiency compound fertilizers, and to control the use of low-concentration chemic...

Problems solved by technology

With the combined effects of population, economy, and resources, and concerns about ecological and environmental issues, some water resources have been transferred to municipal, industrial, and agricultural water use. At the same time, under the increasingly scarce water resources, it is no longer enough to meet the needs of agricultural irrigation.
