Abstract

The invention discloses a method for preparing a multi-element seaweed bio-fertilizer for preventing and controlling unclosing of rice glumes, and belongs to the technical field of fertilizers special for rice. The multi-element seaweed bio-fertilizer takes the following components as raw materials: seaweed meal, compound sodium nitrophenolate, urea, potassium sulphate, monoammonium phosphate, a calcium magnesium phosphate fertilizer, calcium silicate, EDTA chelated zinc, EDTA chelated boron, and a microorganism bacterium agent. Compared with the prior art, the product provided by the invention is natural, green and pollution-free, and can effectively prevent and control unclosing of the rice glumes; the trace elements, such as calcium, magnesium, sulphur, silicon, zinc and boron, are added so as to promote the closing of the rice glumes; the stress resistance of the crops and the fertilizer utilization rate are improved; soil is improved; soil fertility is fertilized; the quality of the crops is improved.

Description

[0001] This application is proposed by the applicant Anhui Laimjia Fertilizer Industry Co., Ltd. "The name of the invention is: a multi-element biological seaweed fertilizer for preventing and controlling the unclosed glume of rice and its preparation method. The application date is August 19, 2014. No.: 2014104076461" divisional application. technical field [0002] The invention belongs to the technical field of special fertilizers for rice, and in particular relates to a multi-element biological seaweed fertilizer for preventing and treating unclosed rice hulls and a preparation method thereof. Background technique [0003] Rice is the largest food crop in my country, with the largest perennial planting area (30 million hectares), accounting for about 30% of the country's grain, the highest yield per unit area, higher than the national average grain output of more than 10%, and the highest total output (about 30% of the country's grain 40%), the largest consumption, the do...
