Paddy rice tillering-promoting, lodging-resisting, and yield-increase-assisting multifunctional fertilizer and application method thereof

Abstract

The invention relates to a paddy rice tillering-promoting, lodging-resisting, and yield-increase-assisting multifunctional fertilizer and an application method thereof. According to the invention, uniconazole, amine hexanoate, calcium chloride, magnesium sulfate, zinc sulfate, borax, EDTA-Fe, EDTA-Mn, EDTA-Cu, silicon fertilizer, and bentonite are crushed and sieved; the mixture is sufficiently mixed by stirring, and is uniformly delivered into a fertilizer granulator; preliminary granulation is carried out according to a round-disk granulation method; the granules are uniformly delivered into a multi-level granular fertilizer round polishing machine, and granulation is carried out again; drying is carried out, such that a water content is below 10%, such that formed granular fertilizer is obtained. Before paddy rice transplantation and before soil preparation before seeding, the fertilizer is uniformly mixed with a composite fertilizer or fine soil, and the mixture is used for application. After paddy rice transplantation, and during a reviving period, the fertilizer is uniformly mixed with a urea fertilizer, and the mixture is used for application. The fertilizer provided by the invention has the advantages of scientific formula, comprehensive functions, simple application, low residue in soil, and safety to succeeding crop. The granular fertilizer is convenient for packaging and transportation, and can be conveniently mixed with other fertilizers. The fertilizer has a substantial effect. With the fertilizer, paddy rice effective tillering can be increased by 2-5 pieces / group, yield can be increased by 10-20%, plant height is substantially reduced, and lodging resistance is improved.

Description

technical field [0001] The invention relates to a multifunctional fertilizer for rice that promotes tillering, resists lodging, and increases production, and its application method. Background technique [0002] As one of the main food crops in my country, rice has the characteristics of wide planting area and large area, which is of great significance to my country's food security, so rice production has always been a hot field of research. In recent years, with the large-scale popularization of hybrid rice and super rice, problems such as poor tillering, lodging, serious pests and diseases, and yield not reaching the ideal level are often encountered during the cultivation process, and the emergence of these problems also seriously limits High-yield and high-quality rice production. In view of this, many related products have appeared on the market to solve the above problems, but these products either have a single function and cannot fully solve the problem; if paclobut...

AI Technical Summary

Problems solved by technology

[0004] In addition, the granulation technology of granular fertilizers such as compound fertilizers and organic fertilizers in my country is still relatively backward, and the granulation process is still immature. At present, there are two main types: one is the extrusion granulation process, which produces cylindrical particles; It is a disc granulation process, which produces particles of different sizes, poor roundness, poor strength, and rough surface

In addition, the fertilizer produced by the two processes still faces its fatal weakness, that is, the particle strength is low, and after many shipments, when it arrives in the hands of consumers, the particles often turn into powder.

More importantly, due to the different sizes and shapes of fertilizer particles, the appearance is not round, not smooth, and it is very inconvenient to mix fertilizers, so it is not popular and directly affects product sales.
