随着农业生产的发展,地下水应用范围越来越广。实践证明,利用地下水种稻,凡用的得当,都起到了很大的增产作用。地下水源到处有,水量充足。但水凉、水贫,井口水温终年在9℃左右,没有自然水肥沃。因而,我们几年来利用地下水种稻,采取了以下几项措施,取得了很好的效果。第一,延长渠道,设晒水池提高水温。据测验每延长100米水线可提高水温0.5℃。如果井口设2000平
With the development of agricultural production, groundwater is applied more and more widely. Practice has proved that the use of groundwater species of rice, where used properly, have played a significant role in increasing production. Groundwater sources everywhere, sufficient water. However, the water is cool, the water is poor and the wellhead water temperature is about 9 ℃ throughout the year. There is no natural water fertile. Therefore, we have used paddy groundwater for several years and have taken the following measures and achieved very good results. First, to extend the channel, set the sun pool to raise water temperature. According to the test every 100 meters extension of the water line can increase the water temperature 0.5 ℃. If the wellhead set 2000 level
