How to increase the germination rate of spring rice seeds
In order to improve the germination rate, the uniformity of the seeds in the spring plowing and the reduction of seed germs. Rice seeds must undergo several aspects of processing before sowing. Specifically reflected in the following three points:
1, drying
Seed sowing before seeding can increase seed coat permeability, enhance water absorption, enzyme activity and seed vigor, and can also reduce the germination inhibitory substances in the seeds (eg, intrachlamyamine A, intrachtalamine B, and stratified acid Concentrations such as, so that the sun has the effect of promoting early germination, increase germination potential and germination rate. General soaking seeds before drying 1-2 days.
2, selected seeds
Since the nutrients needed for the growth of the seedlings before the three-leaf stage were mainly supplied by the seed endosperm itself, the seed plumpness was closely related to the seedlings' weakness. Therefore, the use of seeds that are satiety, grain weight, and uniform in size is an effective measure for nurturing Zhuang.
3, soaking and disinfection
Soaking and disinfecting is one of the important measures for the prevention and control of rice diseases. It can effectively kill pathogens of rice bacillus, rice blast, sclerotia, and halophilic bacteria that adhere to the surface and body of rice germplasm through disinfection, and eliminate the source of primary invasion. Reducing the incidence of diseases in Daejeon and reducing the amount of medication used will have a multiplier effect. Before sowing, seed soaking with seed soaking for 60-72 hours with 4000-5000 times of "soaking seed" or "Shibaoke" is generally used to completely eliminate and prevent species-borne diseases.
