Method for improving germination capability of standardization rice seeds

Abstract

The invention discloses a method for improving the germination capability of standardization rice seeds. The method for improving the germination capability of the standardization rice seeds comprises the following steps that 1, the rice seeds are physically screened to improve the clarity of the rice seeds; 2, liquid screening is conducted on the rice seeds treated in the step 1, and full seed grains are separated from half-full seed grains or abortive grains through the gravity of the rice seeds; 3, chromatic aberration separation is conducted on the rice seeds treated in the step 2, the RGB range of standard seeds is set, and the rice seeds which are not in the RGB range of the standard seeds are removed. According to the method, the 100% clarity of the rice seeds is achieved by jointly adopting physical screening, liquid screening and chromatic aberration separation, and compared with seeds screened through an existing seed screening technique, the seeding quantity is decreased by 40% to 70%, and the seedling rate is 90% or above.

Description

technical field [0001] The invention relates to a method for improving the germination ability of standardized rice seeds, which belongs to the field of rice seed sorting. Background technique [0002] With the reduction of rural labor force and the increase of labor cost in our country, improving rice production efficiency through mechanization is an important measure to promote stable grain production and increase farmers' income. In order to ensure the smooth progress of mechanized production, the orderly and synchronous growth and development of rice is an important prerequisite. In the same ecological region, how to achieve the consistency of rice growth and development, the uniformity, uniformity and robustness of young (seedling) seedlings are the foundation. Therefore, in the case of mechanized production, new and higher requirements have been put forward for the purity, clarity and uniformity of rice seeds. [0003] According to the current cereal seed quality imp...

Problems solved by technology

At the same time, none of the existing seed quality implementation standards regards seed uniformity as one of the indicators of rice seeds

It has been reported that the plumpness of seeds will directly affect the germination rate, seedling rate and seedling growth and development of seeds, thereby affecting rice yield.

[0004] In order to make up for the defects of the current seed quality implementation standards, it is generally used in production to increase the seeding rate of rice seeds for direct seeding and raising (seeding) seedlings, and increase seedling selection and thinning operations in subsequent agricultural operations. On the one hand, it increases the amount of seeds, Production costs increase; on the other hand, it also increases the follow-up agricultural operations and mechanized operations

Although the precision seeding technology can realize the effects of saving seeds, increasing efficiency, and increasing production in principle, it has high requirements on the purity, cleanliness, and uniformity of rice seeds, and there is no effective seed sorting method to effectively match it.
