Abstract

The invention discloses a release-control fertilizer for brassica juncea and preparation method thereof, and belongs to the technical field of fertilizer preparation. The release-control fertilizer for brassica juncea includes following raw materials, by weight, 60-140 parts of a coating material and 200-1200 parts of fertilizer granules. The preparation method includes the steps of crushing, extraction, filtration, concentration, fermentation, granulation, drying, cooling and coating and the like. The release-control fertilizer has a moderated and stable release rate and is balanced in nutrients, is reduced in loss rate and increased in utilization efficiency, can promote quick and healthy growth of the brassica juncea and increase the yield of the brassica juncea, can effectively prevent plant diseases and insect pests and improve soil environment, and can maintain ecological environment protection. The preparation method is simple in operations and is beneficial to popularize and apply.

Description

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