Germinating method for sunflower seeds

Abstract

The invention discloses a germinating method for sunflower seeds, and relates to the technical field of seed germination. According to the technical scheme adopted by the invention, the germinating method comprises the following steps: firstly, taking a proper number of sunflower seeds and putting the sunflower seeds into a container filled with a treating fluid containing 0.2% KCl and 150 mg / L gibberellin (GA); soaking the seeds for 8 hours at a temperature of 28 DEG C, and then taking out the soaked seeds; and packaging the soaked seeds with a wet towel or gauze, and then putting the packaged seeds into a seed germinating box of 28 DEG C to germinate for 5-7 days. According to the germinating method, the germination rate, the germination potential and the fresh bud seedling quality of the sunflower seeds can be obviously improved.

Description

[0001] technical field [0002] The invention relates to the technical field of sunflower germination, in particular to a sunflower seed germination method. Background technique [0003] At present, there are relatively few researches on the germination technology of sunflower seeds in China, and the germination technology of sunflower seeds is generally adopted 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: sl...

[0003] At present, there are relatively few researches on the germination technology of sunflower seeds in China, and the germination technology of sunflower seeds is generally adopted 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, 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

Sunflower is a popular vegetable that plays an important role in production, but sunflower 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
