The planting of double-cropping early-season seed valleys is mostly carried out at the end of March and early April. Since the critical temperature for the growth of rice seedlings is 12°C, after sowing, the temperature below 12°C lasts for more than three days. If there is no insulation measure, it will rot. . The early-season rice rot in the double-season is not only a waste of seed valley but also a delay in the agricultural season. It is forced to change the double season as a season, and the total rice production is bound to decrease and affect the income of farmers. The skillful sprouting and wonderfully preserved bud technique of the double-crop varieties of early-season rice is a key technology for preventing rotting. The farmers have mastered this technology and can effectively prevent rotting. Now they are introduced as follows: 1. Soak the seed valley with water 2~ After 3 days, remove the floating valley and semi-strong valley. 2. Soak the soaked seed valleys with clean water, drain them, and soak them in hot water at 50°C for 1 to 2 hours. Use 50 kg of hot water for each 50 kg of cereals. After the seeds are put in, mix them immediately. Heat evenly. The hot water at 50°C should not be overheated so as not to burn the seed valley. 3. Remove the soaked grains from the hot water and immediately pack and insulate them. Use large wooden barrels for large quantities, small plastic woven bags, or bamboo baskets. After filling the barrel or bag, the grains are managed to keep warm. 4. After the packaging, the seed valley, after 24 hours began to break the chest, do not go within 24 hours to turn, do not need to check; seed valley 24 hours to start breaking the chest, remember not to water, after 2 to 3 hours, will Turn the inside and outside of the valley once and after all the seed valleys break the chest. If the weather is fine, soak the seed valleys with hot water at 40°C for 1-2 hours, remove and pack the seeds, and plant them on the next day. Seeding, seedlings in the open field can also be planted. If the weather is bad, sowing can be done in clearing and clearing. 5. In case of cold wave, continuous rain, temperature below 12 °C, must not rush to sowing, can be broken chest seed valley, before soaking hot water, it will be spread out in the Valley, about 16 cm thick, flip up and down every day Once, do not pour water, wait until the weather is clear, the temperature above 12 °C, soak the seed valley soaked in hot water at 40 °C for 1 hour, remove and drain on the heap, the next day can be sown. 6. This kind of clever germination, wonderful preservation of buds, seed can be piled up to 15 to 20 days after sowing, will not reduce the outbreak rate, can effectively prevent the rot.
