Microbial foliar fertilizer and preparation method thereof

Abstract

The invention discloses a microbial foliar fertilizer and a preparation method thereof. A formula for the microbial foliar fertilizer comprises the following raw materials in parts by weight: 20-35 parts of animal dung biogas slurry, 1-3 parts of low-molecular-weight organic acid, 10-20 parts of sodium selenite, 0.1-0.5 part of ammonium molybdate, 60-80 parts of potassium fulvate, 1-5 parts of a microbial agent, 1-10 parts of zinc sulfate, 1-5 parts of boric acid, 1-5 parts of an accelerant, 80-100 parts of monopotassium phosphate, 0.5-1 part of manganese sulfate and 10-20 parts of calcium superphosphate, wherein the low-molecular organic acid is composed of diethylamine tetraacetic acid, oxaloacetic acid and citric acid according to a weight ratio of 1: (2-3): (1-1.5); the accelerant is composed of pullulan and tetrasodium iminodisuccinate according to a weight ratio of (0.5-1): (0.3-0.9); and the microbial agent is prepared from Bacillus licheniformis and Bacillus subtilis accordingto a weight ratio of 1: (0.5-0.9). The microbial foliar fertilizer has the double effects of promoting crop growth and preventing and treating plant foliar diseases, greatly reduces the use amount ofchemical fertilizers and pesticides, improves farmland environment quality, and enhances the quality of agricultural products.

Description

technical field [0001] The invention relates to the technical field of microbial fertilizer preparation, in particular to a microbial foliage fertilizer and a preparation method thereof. Background technique [0002] Foliar fertilizer is a fertilizer that directly applies the nutrients required by the crop to the foliage for the purpose of leaf absorption, called foliar fertilizer. At present, there are more than 700 kinds of foliar fertilizers officially registered in my country, but there are many problems in foliar fertilizer products. At present, most of the foliar fertilizers used in agriculture are potassium dihydrogen phosphate, which only contains phosphorus and potassium. The formula ratio is fixed, or it is a compound of hormones and trace elements or amino acids. , low quality, no disease resistance. Microbial fertilizers are a type of specific products containing live microorganisms, which can be used in agricultural production to obtain specific fertilizer eff...
