Embodiment 1

[0046] 1. Seed soaking.

[0047] (1) Seed drying: Spread the seeds for 3 to 5 days in sunny and warm weather. It can sterilize and prevent diseases, intensify the activity of seed enzymes, and also facilitate the water absorption of seeds;

[0048] (2) Seed soaking step: Soak the seeds in a 200-fold diluted 40% formalin solution for about 25-30 minutes. After taking it out, cover the seeds with wet gauze and keep them wet for 2 hours, then rinse them twice with water ; After washing the corn seeds, soak them in 75% alcohol for 30 seconds, then soak them in 0.1% mercury liter for 7 minutes, and then wash them with sterile water for 5 times;

[0049] 2. Soak corn seeds

[0050] Experimental group A: Soak 300 corn seeds of the same variety in 40% formalin solution diluted 200 times for about 30 minutes, then rinse twice with water; wash the corn seeds and put them in 75% alcohol Soak in water for 30s, then soak in 0.1% mercury liter for 7min, then wash with sterile water for 5...

Abstract

The invention discloses a method for improving the corn germination percentage. The method comprises the following steps of (1) seed sunning: spreading and sunning seeds for 3 to 5 days in sunny and warm weather; (2) seed soaking: soaking the seeds into a diluted formalin solution; after the seeds are taken, performing covering to maintain the damp state; then, flushing the seeds by clean water twice; fishing out the seeds; performing drying in the shade; (3) sterilization: after the seeds are cleanly washed, putting the seeds into alcohol to be soaked; next, putting the seeds into 0.1-percentmercury bichloride to be soaked; next, performing cleaning by sterile water; (4) pregermination: uniformly putting the corn seeds onto a germination box with laid germination paper; adding water forsoaking; after the soaking, putting the seeds under the condition of 20 to 25 DEG C to maintain the wet germination. By using the method provided by the invention, the germination rate of the corn seeds is enabled not to be lower than 96 percent; the seedling root system number is great; the root hair is lush; the root volume is great; the seedling period disease cannot happen; the seedling root packing is good; the seedlings turn green after the seeding without seedling survival restoration.

Description

technical field [0001] The invention relates to the field of agricultural planting of modern agricultural technology, in particular to a method for improving the germination rate of corn. Background technique [0002] Corn is an annual monoecious cross-pollinated plant with tall plants and strong stems. It is an important food crop and feed crop. It is also the crop with the highest total output in the world. Its planting area and total output are second only to corn and wheat. Corn has always been known as a longevity food, rich in protein, fat, vitamins, trace elements, cellulose, etc., and has great potential for developing high-nutrition, high-biological function foods. However, due to its complex heredity and rich variety of variations, there are shortcomings in the conventional breeding process, such as too long cycle, too large coefficient of variation, and affecting the growth and development of offspring. Modern biological breeding technology not only overcomes the ...
