Problems solved by technology

[0004] The invention provides a pumpkin 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 increase the 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 pumpkin seedlings, and increase the yield of pumpkins; At the same time, it can effectively prevent pests and diseases, improve the soil environment, and maintain ecological protection

Abstract

The invention discloses a controlled-release fertilizer for pumpkins and a preparation method for the controlled-release fertilizer, and belongs to the technical field of fertilizer preparation. The controlled-release fertilizer for the pumpkins comprises the following raw materials in parts by weight: 60 to 140 parts of a coating material and 200 to 1,400 parts of fertilizer granules. The controlled-release fertilizer for the pumpkins is prepared by the steps of crushing, extraction, filtration, concentration, fermentation, granulation, drying, cooling, coating and the like. The controlled-release fertilizer for the pumpkins is moderate and stable in controlled-release rate and balanced in nutrition, the loss rate of the fertilizer can be effectively reduced, the utilization efficiency of the fertilizer can be improved, pumpkin seedlings can be promoted to grow rapidly and healthily, the yield of the pumpkins can be improved, pest and disease damage can also be effectively prevented, a soil environment can be improved, and ecological and environmental protection can be ensured.

Description

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