How to raise the water temperature by planting rice in well water

The biggest disadvantage of planting rice with well water is that the water temperature is low, which affects the good growth of rice, resulting in the decrease of yield and low quality. Therefore, it is very important to improve the water temperature of planting rice with well water.

First, set up a tanning pool to raise the water temperature. The addition of a tanning pool is an effective measure to increase the water temperature of well water for planting rice. The area of the tanning pool should proceed from the actual situation and take measures according to local conditions. Generally, the area of the tanning pool is 1500m2, which is about 1x20 of the irrigated area of the pump. According to the experimental study, the daytime warming effect of the 2000 square meter tanning pool can reach 3 ℃ in mid-May and 5 ℃ in mid-June, which is of great significance to the early growth and rapid development of rice.

Second, extend the waterway and raise the water temperature. Prolonging the waterway is an effective measure to increase the water temperature and reduce the cost. It has been proved that every 100m extension of the waterway can increase the water temperature by 3 ℃.

Third, pump irrigation during the day and night to raise the water temperature. According to the characteristics of rapid warming of water temperature in the paddy field pool during the day, the water temperature can be increased by 0.6 ℃ by pumping water, storing water and heating in the sun during the daytime. After 16 hours, the water temperature can be increased by 0.6 Mir.

Fourth, remove weeds and raise the water temperature. Weeds in well irrigation channels grow luxuriantly and affect the light. Therefore, it is necessary to remove weeds in channels and pool ridges in time to improve the radiation effect of solar energy on paddy fields, so as to increase the water temperature.
