Problems solved by technology

Boron is also one of the essential trace elements for rice growth, but the available boron content in some rice fields is low, and the application of boron fertilizer is not paid attention to during the rice growth period, resulting in insufficient boron supply for rice growth, affecting rice firmness and grain filling. High yield potential not fully realized

Abstract

A dedicated fertilizer for promoting grain-filling in rice and a preparation method therefor, belonging to the technical field of fertilizers for agricultural production. The fertilizer is prepared by using the following raw materials in parts by weight: 40-50 parts of urea, 18-30 parts of superphosphate, 12-27 parts of potassium chloride, 7-15 parts of potassium silicate, 3-5 parts of bentonite, 4-11 parts of sodium tetraborate decahydrate, 0.1-0.3 parts of N-(N-butyl)thiophosphoric triamide, 0.2-0.8 parts of matrine extract, 0.5-1.1 parts of kudzu extract and 0.5-1.0 parts of aloe extract. A product of the present invention can remarkably promote yield when applied to rice, the production cost is reduced, and the utilization rate of nitrogen fertilizer is improved.

Description

technical field [0001] The invention belongs to the technical field of fertilizers in agricultural production, and in particular relates to a special fertilizer for promoting rice grain filling and a preparation method thereof. Background technique [0002] The yield per unit area of ​​rice is determined by four yield components: effective panicle number, grain number per panicle, seed setting rate and thousand-grain weight. These yield component factors are not only determined by the genetic characteristics of the variety, but also affected by environmental factors and cultivation measures. In terms of production, varieties with strong tillering ability and large panicle type are often more popular, and in rice cultivation, a large amount of nitrogen fertilizer is usually applied in the early stage to build a large rice population, forming more effective panicle numbers and total grains per panicle, but the late fertilizer Insufficient attention to rational application and ...
