Rice sprouting inhibitor and preparation method thereof

Abstract

The invention discloses a rice sprouting inhibitor and a preparation method thereof. The rice sprouting inhibitor consists of the following formula components in parts by mass: 3-5 parts of a coumarin extract, 3-7 parts of eugenol, 4-8 parts of sucrose ester, 3-5 parts of a bitter apricot seed extract, 2-3 parts of maleic hydrazide, 2-6 parts of malic acid, 3-5 parts of a morus alba root extract, 5-7 parts of abscisic acid, 3-4 parts of uniconazole, 1-3 parts of sodium citrate, 1-4 parts of paclobutrazol, 3-5 parts of a salicylic acid extract, and 3-5 parts of a waxberry extract. The rice sprouting inhibitor disclosed by the invention is reasonable in formula, and an experiment verifies that the rice sprouting inhibitor has a very obvious rice sprouting inhibitory effect, and achieves an aim of being safe and preventing sprouting; and the rice sprouting inhibitor is simple in processing and making, is convenient to use, and provides an ideal drug for preventing rice sprouting.

Description

Technical field [0001] The invention relates to the field of inhibitors, in particular to a rice ear sprout inhibitor and a preparation method thereof. Background technique [0002] Rice ear sprouting refers to the phenomenon that rice seeds germinate on the ear at the late stage of maturity and before they leave the mother plant. Rice is one of the important food crops in my country, and the quality of its yield and quality is a matter of national lifeline. In most areas of my country, panicle sprouting will occur in varying degrees during rice grain production, hybrid rice seed production and seed propagation. Due to the long-term rainy climate in the summer and autumn seasons in South China, more than 6% of the rice planting areas have ear sprouting, and the highest ear sprouting rate in hybrid rice production areas can reach 20%; especially in the process of hybrid rice seed production, due to " The extensive use of "920", coupled with the characteristics of shallow dormanc...

AI Technical Summary

Problems solved by technology

Seeds that have undergone ear germination have basically lost their planting value, while for some plants that have not yet shown ear buds, various metabolic changes have often occurred inside the grains to prepare for ear germination, which is more likely to occur during seed storage. Fission, the seed vigor is reduced, and the nutrition, sowing and processing quality of the seeds are also reduced
