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: 50-130 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, and a soil environment is improved.

Description

【Technical field】 [0001] The invention belongs to the technical field of fertilizer preparation, and particularly relates to a potato controlled-release fertilizer and a preparation method thereof. 【Background technique】 [0002] Chemical fertilizers have been recognized as playing a pivotal role in increasing crop yields. At present, the utilization rate of chemical fertilizers is less than 30%, and the rest is lost with soil and water. 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 is listed as a key development support project by the state. At present, fertilizers with slow and controlled release functions can basically only play the role of rational utilization of fertilizers and reduce environmental pollution, and rarely can not be applied once, which can not only provide fertilizers for crops, but also play the purpose of pest c...
