Abstract

Disclosed are a rice growth regulator, a preparation method and a usage method thereof. The preparation method of the rice growth regulator includes using main raw materials of, by mass, 0.002%-0.0025% of abscisic acid, 0.5%-2% of urea, 0.1%-0.5% of boric acid and 0.2%-0.5% of monopotassium phosphate, dissolving the abscisic acid by means of ethanol, and evenly mixing the abscisic acid with other raw material aqueous solutions. Foliar spraying is performed at the middle and late stage of the growth of rice, so that stem-sheath assimilative matter translocation and grain filling of the rice are promoted, the setting percentage is increased, rice qualities are improved, and yields are increased; and besides, draught resistance and stress resistance abilities of the rice can be improved. The rice growth regulator, the preparation method and the usage method thereof are safe and environment-friendly, simple in preparation, low in cost, obvious in effect and easy to popularize.

Description

technical field [0001] The invention relates to a rice growth regulator and its preparation method and application method. The growth regulator used in the middle and late stages of rice growth can promote the operation of rice stem sheath assimilates and grain filling, increase grain weight, and improve rice quality. Background technique [0002] Rice is the grain crop with the largest planting area in southern my country. How to scientifically and rationally regulate the growth of rice is of great significance to improve the yield per unit area and rice quality. From the perspective of rice grain firmness, the quality of rice grain filling and grain weight on the same panicle are closely related to the position where spikelets grow on the panicle. Generally speaking, strong grains with early flowering in the middle and upper part of the rice panicle have fast grain filling, good filling, and high grain weight; weak grains with late flowering in the lower part of the panic...
