Method for increasing soybean seed germination rate

Abstract

The invention provides a method for increasing soybean seed germination rate. The method includes the steps: 1) selecting soybean seeds without damaged seed coats and disease spots, flushing the selected seeds for several times by the aid of sterile water, soaking the flushed seeds by the aid of 75% of ethyl alcohol for 2-3 minutes, filtering mixture, and pouring out filtering solution; 2) adding 4-8% of sodium hypochlorite with the temperature ranging from 1 DEG C to 5 DEG C, soaking the seeds for 3-6 minutes, filtering mixture, and pouring out filtering solution; 3) flushing the seeds for 3-5 times by the aid of added sterile water, placing the seeds into treatment solution to soak for 4-6 hours at the temperature ranging from 25 DEG C to 30 DEG C, filtering mixture, and pouring out filtering solution; 4) performing germination on the soybean seeds treated in the step 3) on fine sand or filtering paper at the temperature ranging from 25 DEG C to 30 DEG C. The treatment solution comprises, by weight, 10-20mg / L Fe2SO4.7H2O, 60-100mg / L K2HPO4, 10-30mg / L GA and 0.01-0.5g / L carbon nano tube. According to the method, damage to soybeans can be reduced, and the germination rate further can be remarkably increased.

Description

technical field [0001] The invention belongs to the technical field of leguminous plants, and in particular relates to a method for improving the germination rate of soybean seeds. Background technique [0002] Soybean is one of the six major crops in China. It originated in China, and China's soybean germplasm resources are very rich. Soybean has been cultivated in China since ancient times and has a planting history of thousands of years. Soy contains 38% to 45% protein and 18% to 23% fat. At the same time, soybeans contain many physiologically active substances, such as isoflavones, saponins, lecithin, cellulose, polysaccharides, etc. According to the statistics of the Food and Agriculture Organization of the United Nations, soybean protein accounts for 64.78% of the world's various crop proteins, and soybean oil accounts for 32.5% of edible vegetable oil. The U.S. Food and Drug Administration has determined that any edible product containing more than 2 grams of soybe...

Problems solved by technology

[0004] At present, there are relatively few researches on the germination technology of soybean seeds in China. The soybean seed germination technology is generally adopted in the industry. The main method is: put warm water at 50-55°C 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 to 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
