Natural plant extract rice seed embryo vigor retention agent as well as preparation method and application thereof

Abstract

The invention belongs to the field of a rice seed embryo vigor retention technology, and discloses a natural plant extract rice seed embryo vigor retention agent as well as a preparation method and an application thereof. The rice seed embryo vigor retention agent comprises the following components by weight percent: 49.50-50.00% of a cany tea extract, 25.10-25.50% of a tea extract, 24.50-25.00% of a mulberry leaf extract, 0.15-0.20% of pericarpium citri reticulatae essential oil and 0.20-0.25% of clove essential oil. The natural plant extract rice seed embryo vigor retention agent is reasonable in formulation, fully utilizes the characteristics of all the components, and the components can be reasonably combined and matched, so that the comprehensive bactericidal effect can be achieved; the experiments proves that the natural plant extract rice seed embryo vigor retention agent is very obvious in the sterilizing effect on rice seeds, and effectively inhibits the adverse effect of microbial activities on the seed vigor; the natural plant extract rice seed embryo vigor retention agent achieves the aims of being safe, environment-friendly, practical and effective in the aspect of maintaining the seed vigor; and the natural plant extract rice seed embryo vigor retention agent is easy to process and prepare and convenient to use, and an ideal medicine is provided for maintaining the seed vigor and prolonging the storage period.

Description

technical field [0001] The invention belongs to the research field of rice seed storage technology, and in particular relates to a natural plant extract rice seed embryo vitality retaining agent for maintaining the vitality of rice seed embryos and prolonging the storage period of seeds, and a preparation method and application thereof. Background technique [0002] Rice is one of the three most important grain crops, accounting for 1 / 4 of the world's total grain output, and accounting for more than half of China's total grain output. As the carrier of genetic material, the quality of seeds determines the growth and yield of plants to a large extent. Due to the complexity of rice seed production and the unpredictability of the market and extreme weather, it is often necessary to adjust the short-term storage of a large number of rice seeds between years. However, the vigor and germination rate of rice seeds will irreversibly decrease during storage, that is, aging or deteri...

Problems solved by technology

[0005] Although various technologies for maintaining the vitality of rice seed embryos have their own characteristics, their disadvantages are also obvious: low-temperature storage, sealed packaging and other deoxygenated storage not only consume a lot of manpower, material and financial resources, but also have high costs. The prolongation of the seeds will inevitably lead to aging and deterioration during the storage process.
