May is the single-season rice planting period. Soaking and germination is an important technical aspect of rice sowing. The single-season soaking technique for rice soaking is now described as follows: Before seed soaking, seeds are sun-dried for 2-4 hours in the sun to increase seed vigor and promote rapid water absorption. Selected seeds were rinsed with fresh water or 10%-15% saline to remove pods, semi-semose and diseased granules. Soaking and Disinfection: Dispose the disinfectant with Bicondine, set the concentration to 2000 times (add a small bag to add 100 grams to 4-6 kg of water), pour the selected seeds into disinfectant, and soak the seeds of hybrid rice for 10-12 hours. Indica rice seeds are immersed for 20-24 hours, then washed out and then immersed in clean water for 12-24 hours. High-temperature dew-whitening Immerse the soaked seeds in warm water at about 50°C for 3-5 minutes to maintain the valley temperature at about 38°C, then cover with straw (should avoid high-temperature firing) and keep the temperature at about 35°C for 10-12 hours. Moisturizing and precipitating after dew-whitening to strengthen ventilation, to prevent the temperature is too high, keep 30 °C -35 °C, to promote root growth. After being rooted, it is necessary to properly control the growth of roots, promote the growth of buds, balance the root buds, and achieve short and strong roots. Drenching water is the main measure at this stage. The water temperature should not be too high, generally 25 °C is appropriate. After the roots and buds of the air-sinking exercise are released, they shall be air-dried at room temperature for 1-2 days. The grain thickness of the valley shall be 6-10 cm. Sprouts shall be sprayed or sprayed with cold water to enhance the resistance of the buds and valleys while maintaining the moisture of the buds. Prevent dry buds. In addition, when low-temperature caramel occurs, the seeds should be washed with water and re-germished. Single-season rice seeds are easily exposed to high-temperature sprouting phenomenon after dew-whitening. When this happens, avoid sowing, and you should re-purchase germination.
