In addition, when sowing rice, we should pay attention to several points: first, climatic conditions, second, variety characteristics, and third, we should pay attention to the connection between rice before and after sowing. Generally speaking, when the average temperature steadily passes through 12℃ for three consecutive days, wet seedlings can be planted, and when the temperature stably passes through 10℃, seedlings can be planted or raised and thrown. The sowing date of rice in Pingba, shallow mountain and valley areas below 400 meters above sea level should be from the end of February to March 5; The sowing date of rice in deep mountains and low mountainous areas above 400 meters above sea level should be from March 6 to 15, and in mountainous areas no later than March 20. It is necessary to grasp the sowing date of rice with cold tail and warm head.

In the stage of sowing and seedling raising of rice, low-temperature freezing injury is easy to cause large-scale damage to rice, rice seedlings will turn yellow and die in different degrees due to freezing injury, and there will be seedling shortage in the field. Pay close attention to the weather forecast before and after freezing injury, spray drought-resistant seedling type 2 1 16 on the leaves 2-4 days before low temperature, and use it in time after freezing.
