Early rice intensive seedling soaking germination technology
Early rice seed soaking and germination is characterized by large quantities, strong technology, and high risks. It requires strict disinfection, breaking the chest and neat, and vigorously growing. 1, seed treatment. Soaking seeds before drying for 1-2 days, then selecting with clear water to clear the cereals and alfalfa seeds. 2, seed disinfection. Conventional rice is soaked for 10 hours and hybrid rice is soaked for 6 hours. After draining, 2000 times of the “100 grams†(5 kg of soaked 5 kg per 2 ml of water) or 500 times of strong chlorine is used. "(5 kg of soaked 5 kg per 10 g of water) should be soaked and sterilized for 12 hours, and then the chemicals should be drained and soaked until the water is adequate. 3, soaking time. Soaking with cold water, strictly control the soaking time, avoiding soaking time insufficient affect the germination uniformity, but can not be soaked for too long to prevent "injury." The soaking time is adjusted flexibly according to the temperature of the soaking stage. Conventional rice is generally controlled at about 60 hours (including disinfection), and hybrid rice is controlled within 48 hours (including disinfection). Especially in the early morning 39 must be strictly sterilized as required. 4, warm water to warm up the heap. According to the number of soaking seeds, prepare a corresponding number of pan stoves to ensure that there is a sufficient amount of foot-warmed water. Preheating can take a large cylinder "two open and one cool" method, but also can take the dill basket preheating, temperature control Within 55°C, the time reaches 3-4 minutes. After being warmed up, they are piled up quickly. The bed requires a 25-30 cm thick dry straw and a layer of drained fiber cloth. After being piled up quickly, the inner layer of the cover is covered with fiber cloth, covered with dry straw and heavy objects to keep warm. The dumps are based on the principle of "should not be narrow and wide," and "suitable to be low and not high." Generally, piles are 2-3 meters wide and pile height is not more than one foot. 5, high temperature broken chest. The temperature of ruptured thorax is controlled at 38-40 °C. During the period of breaking the thorax, the seeds are generally not to be turned freely. When the rate of the center of rupture is 85%, the seed can be turned properly and the chest is opened after tidying. 6, suitable temperature germination. Appropriate germination temperature for rice is 26-28°C. During this period, pay attention to the thickness of the planting, timely reseeding, and control the humidity (not dry shell), that is, to ensure that the buds are strong, but also to avoid high temperature injury buds. 7, refining buds. After germination and budding, the seeds should be sown at room temperature for about one day before sowing, so as to prevent the “Hot Valley†from adapting to the outside environment after Shimoda. 4 Wire Video Intercom System,Analog 4 Wire Intercom System,4 Wire Video Doorbells,Doorbell System For Villa,4 Wire Intercom System Zhuhai Mingke Electronics Technology Co., Ltd , https://www.mingke-tech.com
