Description
Technical Field
The invention relates to the technical field of formula fertilizer preparation, in particular to a special formula fertilizer for saline-alkali soil and a preparation method thereof.
Background
At present, the bio-organic fertilizer refers to a fertilizer with both microbial fertilizer effect and organic fertilizer effect, which is compounded by using microorganisms with specific functions and organic materials mainly prepared from animal and plant residues (such as livestock and poultry manure, crop straws and the like) through harmless treatment and decomposition. The biological organic fertilizer has the advantages of reducing or replacing the application of partial fertilizers and pesticides, repairing micro-ecology, improving soil, restoring fertility, improving crop quality, having no pollution to the environment, having no harm to people and livestock and the like. With the enhancement of the green environmental awareness of people and the support of the country to the organic fertilizer industry, various functional organic fertilizers are increasing day by day. By adding specific functional microorganisms into the organic fertilizer, a product which can provide nutrient components for crops to promote the growth of the crops and improve the stress resistance of the crops is prepared, and the method is a research focus for a plurality of fertilizer development enterprises at present.
Saline-alkali soil is a general term for saline soil and alkaline earth. The saline soil mainly refers to saline soil with high chloride or sulfate content, and the soil is alkaline but not necessarily high in pH value. The alkaline earth is soil containing carbonate or heavy phosphate, the pH value is higher, the soil is alkaline, the content of organic matters in saline-alkali soil is low, the soil fertility is low, the physicochemical property is poor, more anions and cations are harmful to crops, and the seedlings of the crops are not easy to promote. The fertilizing principle of the saline-alkali soil is mainly applying organic fertilizer and high-efficiency compound fertilizer, and controlling the use of low-concentration fertilizer. The organic fertilizer contains a large amount of organic matters, plays a role in buffering harmful anions and cations in soil, and is beneficial to rooting and seedling promotion. The high-concentration compound fertilizer has few ineffective components and few residues, but the dosage of the fertilizer cannot be too much each time so as to avoid secondary salinization of aggravated soil, and irrigation needs to be combined after the fertilizer is applied so as to reduce the concentration of a soil solution. The existing fertilizer for saline-alkali soil has poor treatment effect, and cannot improve the crop yield and improve the soil, so the improvement is needed.
