Problems solved by technology

[0004] The invention provides a potato controlled-release fertilizer and its preparation method 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 potatoes, and increase the potato yield; It can also effectively prevent pests and diseases, improve the soil environment, and maintain ecological protection

Abstract

The invention discloses a potato controlled-release fertilizer and a preparation method thereof, and belongs to the technical field of preparation of fertilizers. The potato controlled-release fertilizer comprises the following raw materials in part by weight: 60-130 parts of wrapping materials and 200-1200 parts of fertilizer particles. The potato controlled-release fertilizer is prepared by the following steps of pulverizing, extracting, filtering, concentrating, fermenting, pelleting, drying, cooling, wrapping and the like. Controlled-release speed of the potato controlled-release fertilizer is moderate and stable, nutrition is balanced, wastage rate of the fertilizer can be reduced effectively, utilization efficiency of the fertilizer is improved, quick and healthful growth of potatoes is promoted, yield of the potatoes is improved, plant diseases and insect pests can be prevented effectively, a soil environment is improved, and ecological environmental protection is kept. The preparation method of the fertilizer is easy to operate, and is convenient to popularize and use.

Description

【Technical field】 [0001] The invention belongs to the technical field of fertilizer preparation, and in particular relates to a potato 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 con...
