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 before sowing can increase the permeability of seed coat, enhance water absorption, enzyme activity and seed vigor, and can also reduce the germination inhibitory substances in seeds (such as: Intracuneamine A, Intrachamber amine B , from the concentration of acid, etc.), so 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 Because the seedlings need to grow before the three-leaf stage, the nutrient needed for their growth is mainly supplied by the seed endosperm itself, and the seed plumpness is closely related to the seedling's strength. Therefore, the use of seeds that are satiety, grain weight, and uniform in size is an effective measure for nurturing Zhuang.
3. Soaking, soaking, soaking, soaking, and soaking are one of the important measures for the prevention and control of rice diseases. By disinfecting, it can effectively kill the pathogens of rice bacillus, rice blast, sclerotia, and flax that adhere to the surface and body of rice seeds. The primary source of invasive disease is to reduce the incidence of disease in Daejeon and reduce the amount of medication used, which has 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.
