Rice seed germination method

Abstract

A rice seed germination method relates to the technical field of rice germination. The technical scheme of the method is as follows: placing a moderate amount of rice seeds in a container containing a 0.2% KCl and 150mg / L gibberellic acid (GA) treatment solution; immersing the rice seeds at 28 DEG C for 8 hours and then taking out the seeds; packaging the rice seeds with a wet towel or a piece of gauze and then placing the packaged rice seeds in a germination box at a temperature of 28 DEG C for 5-7 days. The rice seed germination method can achieve the remarkable improvement on the germination ratio, germination momentum and seedling freshness quality of the rice seeds.

Description

technical field [0001] The invention relates to the technical field of rice germination, in particular to a method for germination of rice seeds. Background technique [0002] At present, there are relatively few researches on the germination technology of rice seeds in China. The rice seed germination technology is generally used in the industry. The main method is: put warm water at 50~55℃ in a clean container, and the water volume is 5% of the seed volume. double, soak the seeds in warm water and stir continuously, stop stirring when the water temperature drops to 30°C, and then soak for 8-12 hours to make the seeds absorb enough water, then drain the water, wrap it with gauze, and then wrap the outside Put soaked sacks or towels in pots for germination. This method is called soaking seeds in warm soup. This is the most commonly used method for germination at present. This method is simple and convenient, but there are many problems: slow seed emergence, bud vigor Weak,...

This method is called soaking seeds in warm soup. This is the most commonly used method for germination at present. This method is simple and convenient, but there are many problems: slow seed emergence, bud vigor Weak, irregular emergence, serious phenomenon of large and small seedlings, if the seeds are dormant, the emergence speed will be slower, and the germination rate is low

Rice is a popular crop that plays an important role in production, but rice seeds germinate slowly and irregularly, and are prone to natural aging during storage, resulting in reduced vitality. Therefore, how to speed up seed germination and promote seed emergence is very important
