Abstract

The invention discloses a composite type biological pesticide fertilizer for preventing a rice disease and a preparation method thereof. The composite type biological pesticide fertilizer is composed of the following raw materials by weight percentage: 25-35% of any one of rapeseed cake or cotton seed cake, a peanut cake and tea fruit cake, 25-40% of fragrant eupatorium herb, 5-10% of goldthread, 5-15% of folium eucalypti, 5-15% of validamycin soluble powder, 3-8% of carbendazim, 3-8% of water-soluble boron, 5-10% of water-soluble zinc and 2-5% of copper sulfate solution. The preparation method comprises the following steps of: step 1, crushing any one of the rapeseed cake and the like into a cake; crushing the goldthread into grains; and cutting the fragrant eupatorium herb and the folium eucalypti into blocks or strips; step 2, mixing the cake with industrial acid and water to prepare an effective component extracting solution; step 3, respectively crushing the fragrant eupatorium herb, the goldthread and the folium eucalypti and adding the water to prepare the effective component extracting solution; and step 4, adding the effective component extracting solution, the validamycin soluble powder and the like into a reaction kettle to prepare a finished product. The product disclosed by the invention is green and environment-friendly and has higher fertilizer effect; and the composite type biological pesticide fertilizer has good disease-resistant sterilizing effects of Pyricularia oryzae, seedling blight and banded sclerotial blight.

Description

technical field

[0001] The invention relates to an agricultural fertilizer, in particular to a compound biomedical fertilizer for preventing and treating rice diseases and a preparation method thereof. Background technique

[0002] In recent years, with global warming, my country's annual average temperature has risen, regional precipitation and river runoff fluctuations have increased significantly, and extreme weather and climate events have increased. These diseases are very serious. These diseases are not obvious in the early stage and are easily overlooked by people. It is too late to prevent and control when the disease is serious. Although the existing chemical agents play an important role in bacteriostatic and bactericidal aspects, they are easy to cause germs and pests. Drug resistance needs to be improved. Contents of the invention

[0003] The technical problem to be solved by the present invention is to provide a compound biomedical fertilizer for preventing an...
