How to solve the rice grain does not germinate

Before germination, you need to soak the seed, soaking the seed can play the effect of sterilization. After soaking and sterilizing the seeds, you can germinate. According to the requirements of seed germination on the temperature, the key to good germination is to master the high temperature broken chest, moderate temperature germination, low temperature drying germination.

High-temperature chest breaking is to absorb enough water seeds with 50 ℃ to 60 ℃ of warm water to soak the seeds for 35 minutes, and then put into the pile of grass and maintain a temperature of 38 to 40 ℃, so that the seed chest breaking. At this temperature, you can ensure that the seeds germinate quickly and neatly.

High temperatures should be prevented from burning the germination at this stage, with a minimum germination temperature of 10°C to 12°C, an optimum temperature of 30°C to 32°C and a maximum of 40°C. Longer than 42 ℃ will inhibit the growth of germ and radicle, root and bud death. No water replenishment before breaking the chest, breaking the chest to turn the seed, so that the seed germination is uniform. Appropriate water replenishment after breaking the chest, pay attention to ventilation to increase oxygen.

Moderate temperature germination is the seed broken chest to turn the pile. The seed pile will be spread thin, drench cooling, drenching temperature should not be too low, the seed temperature should be kept at 25 to 30 ℃ under the appropriate temperature germination, the seed pile to keep wet, and maintain the oxygen supply.
