Abstract

The invention discloses a slow release pesticide-fertilizer for preventing and controlling sclerotinia of strawberries. The slow release pesticide-fertilizer comprises a pesticide-fertilizer core andan envelope. The pesticide-fertilizer core is prepared from the following raw materials in parts by weight: 50-60 parts of cake fertilizer, 2-4 parts of alpha-amylase, 10-15 parts of potassium dihydrogen phosphate, 8-12 parts of a water-soluble phosphate fertilizer, 15-18 parts of urea, 2-4 parts of ferrous sulfate, 0.5-1 part of zinc sulfate, 0.4-1 part of copper sulfate, 1-3 parts of sodium ascorbate, 9-15 parts of ethyl silicate, 3-5 parts of a silane coupling agent, and 8-11 parts of a Chinese herbal medicine extract, wherein the Chinese herbal medicine extract is prepared from wild pepper, cortex phellodendri, melia azedarach leaves, leucaena leucocephala leaves and cortex fraxini. The envelope is prepared from the following raw materials in parts by weight: 9-13 parts of polyvinyl alcohol, 1.5-2.2 parts of chitosan, 0.5-0.8 part of silica, 2-4 parts of starch, 1-3 parts of cellulose, 3-6 parts of gelatin, and 71-83 parts of water. The invention also provides a preparation methodof the slow release pesticide-fertilizer. When used for preventing and controlling sclerotinia, the slow release pesticide-fertilizer can effectively improve the disease resistance of strawberries, increase the yield and quality of strawberries, and greatly reduce the labor intensity of farmers.

Description

technical field [0001] The invention belongs to the technical field of crop fertilizers, and in particular relates to a slow-release medicinal fertilizer for preventing and treating strawberry sclerotinia and a preparation method thereof. Background technique [0002] Strawberry sclerotinia is a fungal disease, which occurs in every strawberry producing area in the country. The disease mainly harms strawberry petioles, flower stalks and fruits. The diseased part is light brown water-soaked spots at first, and gradually expands into a fusiform or irregular shape. Under high humidity conditions, the diseased part is soft and rotten, and a large number of cotton-like white hyphae grow on the surface of the diseased spot, and then the mycelium gathers to form rats. Fecal or irregular black sclerotia. The whole leaves of the infected plants are dead and rotten, the flower stalks are dry, and the growth points of the roots and stems are normal. New leaves can be regenerated in t...
