Abstract

The present invention discloses a potato controlled release fertilizer and preparation method thereof, and belongs to the technical field of the preparation of fertilizer. The potato controlled release fertilizer comprises the following ingredients by weight: 20-80 parts of a wrapping material and 150-600 parts of fertilizer particles. The controlled release fertilizer is prepared by the steps of crushing, extracting, filtering, concentrating, fermenting, granulating, drying, cooling, and packaging. The potato controlled release fertilizer has moderate and stable controlled release rate and balanced nutrition, promotes rapid and healthy growth of potato, and increases potato production; the potato controlled release fertilizer of the present invention is not only effective in preventing pests, but also can improve soil environment. The preparation method of the controlled release fertilizer potato is simple, and is beneficial to popularization and application.

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-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 widely...
