Rice overgrowth-controlling, lodging-resistant and yield-increasing agent and application thereof

Abstract

The invention discloses a rice overgrowth-controlling, lodging-resistant and yield-increasing agent and an application thereof. The rice overgrowth-controlling, lodging-resistant and yield-increasing agent mainly comprises a plant growth regulator and a fertilizer, wherein the regulator is brassinolide and paclobutrazol or uniconazol, and the fertilizer is one or combination of more than two of substances containing N/P/K/B/Zn/Ca/Cu/Fe/Mn/Mo/Me/S/Cl/Si and other elements, such as urea, potassium dihydrogen phosphate, diammonium phosphate, calcium carbonate, potassium nitrate, silicon fertilizer, zinc sulfate, ferrous sulfate, potassium chloride, boric acid, borax, copper sulfate, ferrous sulfate, molybdenum fertilizer, magnesium sulfate, potassium sulfate, manganese sulfate and rare earth fertilizer. The rice overgrowth-controlling, lodging-resistant and yield-increasing agent has good safety and can effectively shorten the length between neck-panicle nodes and top second nodes of rice and enhance lodging resistance of rice; simultaneously, the rice overgrowth-controlling, lodging-resistant and yield-increasing agent can not affect safe dates of full heading and the grain number per spike of rice, prolong the service life of functional leaf of rice, improve the seed setting rate and the 1000-grain weight of rice and significantly affect the yield of rice. The rice overgrowth-controlling, lodging-resistant and yield-increasing agent is suitable for various types of rice, including conventional rice, hybrid rice and super hybrid rice, and has the advantages of low cost and high performance-price ratio.

Description

technical field [0001] The invention relates to the field of increasing rice production, in particular to a special rice-controlling, anti-lodging and yield-increasing agent and an application thereof. Background technique [0002] Rice is an important food crop in my country, and it is also a high-yield crop. It occupies a pivotal position in food production. Food security is also the top priority of my country's national economy and people's livelihood. Rice lodging is a common problem in rice production, and it has become one of the important factors for high and stable yield. Lodging can lead to the cessation of photosynthesis and grain filling, which greatly affects the quality of rice. At the same time, it brings inconvenience to harvesting and threshing, and the phenomenon of threshing and ear buds occurs, which increases the loss rate of rice. Under the action of strong wind and heavy rain, rice is more likely to cause lodging of the stems, and the resulting reducti...

Problems solved by technology

[0003] With the development of society, scientific and technological breeding experts generally realize that although dwarf varieties are beneficial to lodging resistance, they are not conducive to the improvement of high yield. The mainstream development direction of rice production is high-stalk varieties with high quality and high yield. The variety is high, but due to poor management or the influence of the external environment, lodging will also occur
