Method for preparing organic fertilizer for potatoes

Abstract

The invention relates to a method for preparing an organic fertilizer for potatoes. The organic fertilizer is prepared from the following raw materials in parts by weight: animal excreta, soybean straws, bean pulp, traditional Chinese medicinal materials, microelements, urea, a potash fertilizer, plant ash and humic acid; the traditional Chinese medicinal materials are flos lonicerae, radix euphorbiae ebracteolatae, sun euphorbia herb and radix glycyrrhizae. The preparation method comprises the following steps: fermenting the traditional Chinese medicinal materials and an organic fertilizer respectively, pouring a traditional Chinese medicinal material fermentation concentrate into the organic fertilizer, uniformly stirring and mixing, and drying at low temperature; detecting the content of nutrients, adding urea, the potash fertilizer and the microelements according to the content detection result, mixing, and then feeding the materials into a granule forming machine for forming; adding the humid acid which is prepared according to a proportion to the granules, and coating; feeding the coated granules to an air-flowing type medium temperature drier, and drying to obtain the organic fertilizer for potatoes. The organic fertilizer for potatoes has the capabilities of improving the soil structure, improving the fertility of soil, increasing the yield and reducing the use amount year by year until no chemical fertilizer and pesticide is used, thus finally realizing no-tillage farming. Meanwhile, the organic fertilizer has the functions of suppressing survival and reproduction of harmful microorganisms, lightening and gradually eliminating soil-borne plant diseases and insect pests and successive cropping obstacle, enhancing the water seepage, water retention and gas permeation capabilities and promoting soil granulation, and is high in viable content and green without residues.

Description

technical field [0001] The invention belongs to the technical field of organic fertilizers, and in particular relates to a method for preparing potato organic fertilizers. Background technique [0002] Potato, scientific name potato, is a perennial herbaceous plant belonging to the family Solanaceae, and its tubers are edible. It is the fourth most important food crop in the world, second only to wheat, rice and corn. Also known as ground eggs, yam eggs, and yams, potatoes have high starch content, which can reach 60%-80% of dry matter, so many areas treat them as food crops. Potatoes are rich in vitamins and proteins, and many areas use them as vegetables. treat. Potatoes are both food crops and vegetable crops, so people pay more and more attention to the cultivation of potatoes. In 2015, China will launch the strategy of turning potatoes into a staple food, promoting the processing of potatoes into staple foods such as steamed buns, noodles, and rice noodles. Potatoes w...
