Composite nutritional bacterial agent for saline-alkaline land crop planting, and preparation method and application method of bacterial agent

Abstract

The invention discloses a composite nutritional bacterial agent for saline-alkaline land crop planting. The composite nutritional bacterial agent for saline-alkaline land crop planting comprises the following components in parts by weight: culture: 18 to 22 parts of cortinarius russus, 12 to 18 parts of cytophaga, 18 to 22 parts of gray ring suillus bovines, 15 to 20 parts of bacillus megatherium,8 to 12 parts of bacterial enzyme, 20 to 30 parts of a rooting powder and 4 to 6 parts of bacillus cereus; and culture medium: 1.5 to 2.5 parts of amino acid, 2.5 to 3.5 parts of glucose, 1.3 to 1.8parts of tea polyphenol, 1.3 to 1.8 parts of vitamin and 0.35 to 0.6 part of amino acid. The invention discloses a preparation method and a use method of the bacterial agent. The culture can promote synthesis of biomacromolecules and induce formation of adventitious roots or adventitious buds of the plants by intensifying, regulating and controlling the plant endogenous hormone content and the activity of important enzyme; due to the addition of the bacterial agent, the decomposition speed of the straws returning to the field can be increased and the improved effectiveness on the soil of a saline and alkaline land is durable; and the composite nutritional bacterial agent for saline-alkaline land crop planting can improve the soil and also can accelerate the growth of crops and regulate themetabolic intensity of the plants so as to fulfill the aims of increasing the survival rate of seedling growing and afforestation, increasing the yield of the crops and improving the quality and theresistance of the crops.

Description

technical field [0001] The invention relates to a compound nutrient bacterial agent for planting crops in saline-alkali land, and also relates to a preparation method and a specific application method of the compound bacterial agent. 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. [0003] my country has a vast area of ​​saline-alkali land. With the continuous development of agricultural technology, the country pays more and more attention to the developme...

AI Technical Summary

Problems solved by technology

The effect of traditional improvement methods is slow, and the rate of salinization and alkali return is high. If the crops are not irrigated in time during the growth cycle, the salinity and alkali return will easily damage the crops, and the risk of yield reduction is high.
