Scientific and technological analysis shows that the optimal temperature range of rice tillering stage is about 30 degrees Celsius, which is the most favorable temperature for rice tillering growth. At this temperature, rice tillers are the fastest, the most abundant, and the best quality. If the temperature is too low or too high, it will affect the growth of rice tillers. If the temperature is below 20 degrees Celsius, the tillering speed of rice will be slower and the number will be reduced; If the temperature is higher than 35 degrees Celsius, the quality of rice tillers will deteriorate, and even the tillers will die.
In addition, the temperature management of rice during the tillering period also needs to consider the temperature difference between day and night. The proper temperature difference between day and night is conducive to the growth of rice tillering. During the day, the temperature can be slightly warmer to speed up the tillering; At night, the temperature can be slightly cooler to reduce the consumption of nutrients by respiration. Generally speaking, it is ideal to keep the temperature difference between day and night around 5 degrees Celsius.
In order to achieve optimal temperature management at the tillering stage of rice, a series of measures need to be taken. First of all, it is necessary to choose a suitable sowing date to avoid growing rice in extreme temperatures. Secondly, field management should be strengthened to keep the water layer and soil moisture in the field appropriate to regulate the temperature. In addition, measures such as mulching and strengthening ventilation can also be taken to keep warm and moisturize and create a suitable environment for rice growth.
In short, scientific and technological analysis shows that the optimal temperature of rice tillering stage is about 30 degrees Celsius, and the appropriate temperature difference between day and night is also conducive to the growth of tillering. In order to achieve optimal temperature management, a series of measures need to be taken to regulate temperature and humidity and create a suitable environment for rice growth. This will not only improve the yield and quality of rice, but also contribute to sustainable agricultural development.
