Abstract

The invention relates to a drip-irrigation type salt stress-alleviating and disease-preventing biological bacterial fertilizer and a preparation method thereof. The drip-irrigation type salt stress-relieving and disease-preventing biological bacterial fertilizer comprises nutrition carriers, additives, microelements and functional microorganisms, wherein the nutrition carriers comprise two or more of humic acid, glutamic acid, urea, corn flour, potassium sulphate, potassium chloride and diammonium hydrogen phosphate; the additives comprise two or more of bentonite, sodium carboxymethyl cellulose, sodium alginate an polyvinyl alcohol; the microelements comprise one or two of boric acid an ammonium molybdate; and the functional microorganisms is formed by combining salt stress-alleviating growth-promoting bacteria and disease-preventing growth-promoting bacteria, wherein the salt stress-alleviating growth-promoting bacteria is one or two selected from pseudomonas putida and azotobacter chroococcum; and the disease-preventing growth-promoting bacteria is one or two selected from bacillus subtilis and bacillus megatherium. The biological bacterial fertilizer is in a liquid dosage form, has relatively high effective viable count and relatively long quality guarantee period. The effective viable count of the biological bacterial fertilizer is higher than or equal to 10<10> cfu/mL; and total nutrient content of (N+P2O5+K2O) is higher than or equal to 12%.

Description

Technical field [0001] The invention relates to the field of microorganisms, in particular to a drip irrigation type salt-relieving and disease-preventing biological bacterial fertilizer and a preparation method thereof. Background technique [0002] Xinjiang is located in the northwestern inland of my country. Due to strong ground evaporation and crop transpiration, the salt in the groundwater moves upward, which causes the accumulation of salt in the soil. At the same time, improper agricultural irrigation and water conservancy facilities cause soil salinization. Thereby affecting agricultural planting. Nearly 80 counties (cities) in Xinjiang are facing serious soil salinization problems, especially in southern Xinjiang. For example, the salinized arable land in Kashgar accounts for about 48.72% of the area's arable land. In recent years, various types of secondary salinization have become more and more serious, resulting in crop shortages, broken ridges, and reduced yields, wh...
