1．修晒水池。在水田井附近修晒水池，并设溢水口，使表层水进田。晒水池深度应超过0．7米，晒水池越大提高水温的效果越明显。2．延长渠道。渠道每延长100米，水温可提高luC～2．SC。因此，可以围绕稻田修环形渠道。3．渠道覆膜。在渠道上方架上竹片或柳条等拱架，覆上废旧农 1. Repair sun pool. In the paddy fields near the sun basins, and set overflow port, the surface water into the field. The depth of the sun pool should be more than 0.7 meters, the greater the sun pool to increase the effect of water temperature more obvious. 2. Extend the channel. Each extension of the channel 100 meters, the water temperature can increase luC ~ 2. SC. Therefore, we can revise the circular channel around the rice fields. 3. Channel coating. Put bamboo or wicker arches at the top of the channel, and cover the old farmers
