Abstract

The invention discloses a preparation method of a rice-lobster mixed culture slow-release fertilizer for reducing diseases and insect pests, wherein the preparation method includes the following steps: mixing coconut shell charcoal, calcined kaolin, vermiculite powder and sepiolite, adding the mixture into a sodium hydroxide solution, soaking, filtering, washing and drying, adding urea, monoammonium phosphate, calcium triple superphosphate, potassium dihydrogen phosphate, a potassium magnesium sulfate fertilizer, EDTA chelated zinc, EDTA chelated manganese, sodium selenite and boric acid, andmixing evenly to obtain a premix a; mixing fermented tea seed meal, peat soil, bagasse, corncob powder, corn germ meal and oat bran, adding water, and adding an EM microbial agent, and fermenting to obtain a premix b; and mixing the premix a, the premix b and gelatin evenly, adjusting the pH value of the system to 6.4-6.9 by hydrochloric acid, adding high-temperature-resistance alpha-amylase, stirring at room temperature, carrying out enzyme deactivation, adding a slow-release enhancer and glutaraldehyde, stirring, carrying out spray drying, granulating, and drying to obtain the rice-lobster mixed culture slow-release fertilizer for reducing the diseases and insect pests.

Description

technical field [0001] The invention relates to the technical field of slow-release fertilizers, in particular to a method for preparing slow-release fertilizers for rice and lobster polyculture for reducing pest damage. Background technique [0002] More and more people are beginning to try ecological farming, such as raising crayfish in rice fields. This polyculture method is to organically combine planting and aquaculture, and make full use of the artificially created ecosystem to make crayfish and rice mutually beneficial. Symbiosis. Raising lobsters in rice fields has three advantages: one is to increase production and income; the other is that lobsters can eat wild weeds and aquatic organisms in the fields instead of rice seedlings, and can also eliminate harmful larvae including mosquitoes, which can play a role in weeding The third is that the swimming and foraging of fish and shrimp help rice fields to loosen soil, run water, and ventilate, increase the dissolved o...
