Special compound fertilizer for walnut cultivation

Abstract

The invention discloses a special compound fertilizer for walnut cultivation and a preparation method thereof. The fertilizer is prepared from the raw materials such as soybean meal, calcium magnesium phosphate fertilizer, potash magnesium sulfate fertilizer, camellia oleifera meal, walnut dregs, livestock manure, zinc sulfate heptahydrate and borax by the steps of grinding, sieving, fermentation, stirring and uniform mixing. The special fertilizer consists of the following raw materials in percentage by weight: 10-45% of soybean meal, 25-45% of camellia oleifera meal, 10-25% of calcium magnesium phosphate fertilizer, 9-19% of potash magnesium sulfate fertilizer, 25-35% of walnut dregs, 9-19% of livestock manure, 0.1-2% of zinc sulfate heptahydrate and 0.1-2% of borax. In the invention, the formula is scientific and reasonable; the weight percentage of the raw materials is adjusted according to the soil regime of Yuexi county to obtain the special fertilizer, the walnut nutrition is balanced, and better growth of walnuts is promoted; and meanwhile, the soil environment is improved, the quality and oil yield of walnuts are increased, and the special fertilizer is safe and free of pollution.

Description

technical field [0001] The invention relates to the technical field of fertilizers in agricultural and forestry production, in particular to a special fertilizer for walnut cultivation and a preparation method thereof. Background technique [0002] In recent years, walnut planting has also adopted organic special fertilizers. However, in the process of production and use, traditional organic fertilizers are dirty, smelly, unhygienic, low in nutrient content, slow in fertilizer efficiency, large in size, complicated in production process, and unsuitable for use. Convenience and other disadvantages. [0003] For this reason, it is necessary to develop and utilize the rich local bio-organic waste resources according to local conditions, while turning waste into treasure, effectively mitigating or eliminating environmental pollution, and according to the soil fertility conditions of Yuexi, it is very necessary to formulate organic fertilizers suitable for the cultivation and app...
