Abstract

The invention discloses a sweet potato controlled release fertilizer and a preparation method thereof, and belongs to the technical field of fertilizer preparation. Raw materials of the sweet potato controlled release fertilizer comprise, by weight, 60-120 parts of a coating material and 200-1200 parts of fertilizer particles, and the sweet potato controlled release fertilizer is prepared through the steps of crushing, extracting, filtering, concentrating, fermenting, granulating, drying, cooling and packaging. The sweet potato controlled release fertilizer has the advantages of moderate and stable controlled release rate, balanced nutrition, effective reduction of the loss rate of fertilizers, promotion of rapid and healthy growth of sweet potato, improvement of the output of the sweet potato, effective prevention of diseases and pest damages, and soil environment improvement.

Description

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