Abstract

The invention relates to the technical field of agricultural planting, in particular to a special controlled-release microbial fertilizer for peanuts in a continuous cropping field and a preparation method thereof. The fabric comprises an outer layer, a middle layer and an inner layer, the fertilizer efficiency period of 50-60 days can be achieved through the three-layer structure, and the purposeof two-time release is achieved.

Description

technical field [0001] The invention relates to the technical field of agricultural planting, in particular to a special controlled-release microbial fertilizer for peanuts in continuous cropping fields and a preparation method thereof. Background technique [0002] With the expansion of my country's peanut area, the continuous cropping area has increased rapidly, and Shandong alone has reached more than 4 million mu per year. Studies have shown that continuous cropping of peanuts can reduce the yield by more than 10% for one year, and 15-20% for two years. Allelochemicals of peanut root exudates with autotoxicity, such as: cinnamic acid, lauric acid, myristic acid, palmitic acid, oleic acid, stearic acid, 2,4-di-tert-butylphenol, 2,6-di-tert-butylphenol Butylphenol, phthalic acid, p-hydroxybenzoic acid, 2,4-dimethylbenzaldehyde, etc. These substances mainly cause damage to cell membranes, destroy cell structure, inhibit root growth, root vitality and invertase activity, R...
