Abstract

The invention belongs to the field of rice sprouting inhibitors, and discloses a compound type rice sprouting inhibitor as well as a preparation method and application thereof. The compound type rice sprouting inhibitor is prepared from the following raw materials in percentage by mass: 17.00 to 18.00% of coumarins extract, 15.00 to 16.00% of bitter apricot seed extract, 10.00 to 11.00% of mulberry root extract, 15.00 to 16.00% of salicylic acid extract, 14.50 to 16.00% of green plum extract, 20.00 to 22.50% of waxberry extract, 3.00 to 3.50% of paclobutrazol and 1.50 to 2.00% of abscisic acid. The compound type rice sprouting inhibitor is reasonable in formula, is verified to have a very obvious inhibitory effect for rice sprouting by experiments, and achieves the aims of being safe and preventing sprouting; the compound type rice sprouting inhibitor is simple in processing and making and convenient to use, and an ideal drug is provided for preventing rice sprouting.

Description

technical field [0001] The invention belongs to the field of rice panicle germination inhibitors, in particular to a composite rice panicle germination inhibitor and its preparation method and application. Background technique [0002] Rice ear germination refers to the phenomenon that rice seeds germinate on the ear at the late stage of maturity and before they are separated from the mother plant. Rice is one of the most important food crops in my country, and its yield and quality are issues related to the lifeline of the nation. In most areas of my country, different degrees of ear germination will appear in the process of rice grain production, hybrid rice seed production and seed propagation. Due to the long-term rainy climate in summer and autumn in southern China, more than 6% of the rice planting areas have ear germination, and the highest rate of ear germination in hybrid rice production areas can reach 20%; especially in the process of hybrid rice seed production,...
