Deng Chuanshan of Fengyang County, Anhui Province, said on April 15 that he had immersed 5 kg of hybrid rice on April 10 and had already infiltrated enough water on the 15th to germinate. However, on the 18th of the weather, the weather will be low temperature and rain. Weather, this may have adverse effects on rice sowing and nursery. He asked what the current batch of rice should be treated, whether to continue soaking or normal germination. After the rice seeds are immersed in water, they are first mechanically absorbed, and the starch in the glume and endosperm can absorb a certain amount of moisture. At a suitable temperature, about 2 days or so later, the germ begins to germinate and enter the physiological water absorption stage. At this time, the starch in the endosperm will be degraded into sugars by the action of enzymes. For embryo germination and growth and utilization. Depending on the temperature, the seed will start to burst after 3-4 days of soaking. The temperatures in Fengyang and other places were lower in April and the time from soaking to suitable germination was relatively long. However, under normal conditions, the rice seeds will enter the thoracic period 5 days after soaking. During this period, a higher temperature is favorable for rice breakage and budding, and adopting high-temperature germination measures is conducive to neat bud emergence and increase germination rate. If soaking at low temperatures continues, the starch in the endosperm will continue to degrade to produce sugar, and the embryos will have weak motility at low temperatures, which will lead to the phenomenon of seed caramelization, affect the growth of embryos, and even cause the death of embryos, seriously affecting rice. Germination rate and seedling quality. In recent years, in the production of direct seeding rice in Maijing, the phenomenon of continuous low temperature and rain and low seedling emergence after sowing has also been caused mainly by this reason. The above-mentioned rice seeds that have been infiltrated with water cannot be soaked or soaked at a low temperature. They should be germinated in time, and should be properly air-dried when about 80% of the rice seeds are whitened, and the temperature should be gradually lowered. About 1 day after the roots and buds have a certain length, the temperature can be reduced to normal room temperature, and the humidity can be properly maintained. The growth rate of budded rice seeds at low temperatures will be slowed down. Seeds can be planted in cold tail warmer depending on the weather conditions. Normal management after sowing can ensure higher emergence and seedling rate.
