Problems solved by technology

Cytological studies have shown that the application of multivariate fertilizers to plants will produce antagonistic effects, which is not conducive to the absorption of fertilizers by plants. When the concentration is high, plants will suffer instead.

Abstract

The invention discloses a multi-element biological seaweed fertilizer for preventing unclosed rice hulls and a preparation method thereof, belonging to the technical field of rice special fertilizers. Its raw material components are calculated by weight: 10-50 parts of seaweed powder, 2-15 parts of sodium nitrophenolate, 150-450 parts of urea, 150-450 parts of potassium sulfate, 100-400 parts of monoammonium phosphate, calcium magnesium phosphate fertilizer 50-250 parts, calcium silicate 0-50 parts, EDTA chelated zinc 2-15 parts, EDTA chelated boron 2-15 parts, microbial agent 15-40 parts. Compared with the prior art, the product of the present invention is natural, green and pollution-free, and can effectively prevent rice chaff closure; adding medium and trace elements such as calcium, magnesium, sulfur, silicon, zinc, boron, etc., can promote rice chaff closure; Stress resistance and fertilizer use efficiency of crops; improving soil, fertilizing soil fertility, and improving crop quality.

Description

technical field [0001] 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 [0002] 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 domestic trade market is small, rice production and consumption can only rely on domestic self-sufficiency. [0003] Since 2004, cracking and deformation of rice glumes have occurred in many places in the Huaihe River Basin of Anhui, and the phenomenon continues to increase; it has also been reported in Shiling, Suqian, Huangli, Xiangzhou, Guangxi...
