Rice soaking and germination method
Rice production is about to enter the sowing and seedling season. Scientifically mastering the time and method of soaking seeds is the key to improving the germination rate of rice and cultivating it. Therefore, Huinong School reminds the majority of rice farmers to do the following processing before rice seeding:
Sunburn. Soaking rice seeds must be selected before the fine weather Shaizhong 2--3 days, in order to facilitate and improve the germination rate of seed germination of rice. But be careful not to spread the rice seeds on the concrete floor or slate to prevent sunburning the seeds. Pay attention to turning over during the drying process.
Salt water selection. When seeding, the specific gravity of the brine should reach 1.13 (25 kg of water, dissolve 5 kg of salt ) . After the salt is selected, it must be washed twice with water, otherwise the seeds will not sprout.
Seed disinfection and soaking. The selected seeds are treated with 25% Shigak (microbamide) in a bag ( 10 mg) for 50 kg of water , soaked in 40 kg, the water temperature is maintained at 11 to 12 °C , and the seeds are sterilized for 6 to 7 days. Note that when soaking seeds, the water should be 10 cm higher than the rice seeds, and the accumulated temperature should reach 100 degrees, flipping once a day.
Promote germination. Remove the soaked seeds and use a gauze bag to germination. After the rice seeds are warmed up, the temperature is controlled at 30 to 32 °C. If the temperature is too high, the temperature should be turned over. After the whitening is broken, the temperature is controlled at 25 °C. At the time of germination, it is necessary to pay attention to the change of rice temperature at any time. It is suitable for germination and germination. The length of the bud root should be within 2 mm. After urging it, bud in the shade and wait for sowing.
Natural Plant Extract is a kind of solid powder obtained by cleaning, extracting, concentrating and spray drying Chinese herbal fruits and vegetables, without adding any other ingredients; The effective components and essence of plants are extracted, which improves the full utilization rate of plants and is beneficial to human absorption.
The components of plant extracts can be divided into glycosides, acids, polyphenols, polysaccharides, terpenoids, flavonoids, alkaloids and so on. For example, the main component of green tea extract is tea polyphenols. Ginseng extract mainly contains a variety of ginseng monomer saponins; According to different characters, it can be divided into extract, powder, lens, etc., such as violet leaf extract, hang white chrysanthemum extract.
