Abstract

The invention discloses controlled-release fertilizer for Chinese yams and a preparation method of the fertilizer and belongs to the technical field of fertilizer preparation. The controlled-release fertilizer for the Chinese yams comprises raw materials in parts by weight as follows: 4-20 parts of a coating material and 60-120 parts of fertilizer granules. The controlled-release fertilizer for the Chinese yams is prepared through steps of crushing, extraction, filtration, concentration, fermentation, granulation, drying, cooling, coating and the like. The controlled-release fertilizer for the Chinese yams has the moderate and stable controlled-release rate, has balanced nutrition, and can promote the Chinese yams to grow rapidly and healthily, increase the yield of the Chinese yams, effectively control diseases and insect pests, improve the soil environment and maintain ecological environment protection.

Description

【Technical field】 [0001] The invention belongs to the technical field of fertilizer preparation, and in particular relates to a yam controlled-release fertilizer and a preparation method thereof. 【Background technique】 [0002] It has been recognized that chemical fertilizers play a pivotal role in increasing the yield of crops. At present, the utilization rate of chemical fertilizers is less than 30%, and the rest is lost with water and soil. The application of chemical fertilizers not only causes great waste, but also pollutes soil and groundwater resources. Therefore, the development of slow-release fertilizers is listed as a key development support project by the state. . At present, fertilizers with slow and controlled release functions can rarely be used in one application. They can not only provide fertilizer for crops, but also serve the purpose of controlling insects. Because slow and controlled release functional fertilizers save labor and manpower, they are widel...
