Problems solved by technology

[0004] The invention provides a Chinese yam controlled-release fertilizer and a preparation method thereof to solve the problems of low utilization rate caused by the direct use of chemical fertilizers, large residues of agricultural products caused by the use of chemical pesticides, great damage to the human body, and labor force caused by the separate use of pesticides and chemical fertilizers. In order to solve problems such as incompatibility with the decline of the current rural labor force, the controlled release rate of the fertilizer of the present invention is moderate and stable, and the nutrition is balanced, which can effectively reduce the loss rate of the fertilizer, improve the utilization efficiency of the fertilizer, promote the rapid and healthy growth of Chinese yam, and increase the yield of Chinese yam; It can also effectively prevent pests and diseases, improve the soil environment, and maintain ecological protection

Abstract

The invention discloses a release-controlled fertilizer for Chinese yam and a preparation method thereof and belongs to the technical field of preparation of fertilizers. The release-controlled fertilizer comprises the following raw materials, by weight, 80-120 parts of a coating material and 200-1200 parts of fertilizer granules. The preparation method includes the steps of crushing, extraction, filtration, fermentation, granulation, drying, cooling and coating and the like. The release-controlled fertilizer is moderated and stable in release speed, is balanced in nutrients, is reduced effectively in loss rate and increased in utilization efficiency, can promote quick healthy growth of Chinese yam and can increase the yield of the Chinese yam. The fertilizer also effectively prevents plant diseases and insect pests, can improve soil environment and can achieve ecologic 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 and controlled release fertilizers has been listed as a key development support project by the state. At present, fertilizers with slow and controlled release functions can basically only play a role in rational use of fertilizers and reduction of environmental pollution, and seldom fail to achieve one-time application, which can not only provide fertilizer for crops, but also contro...
