我省自本世纪五十年代开始作灌溉试验,过去都是沿用筒测法测定水稻需水量。为了寻求水稻需水量试验方法的新途径,1983年开始采用坑田结合法测定水稻需水量。先在泉州站进行试点,后在龙岩、宁德站开展协作;此外,在泉州站还用坑田结合法、坑测、筒测法同时进行水稻需水量试验,进行 Irrigation experiments have been carried out in our province since the 1950s. In the past, the water requirement of paddy rice was measured by the tube test. In order to seek new ways to test the water requirement of paddy rice, the paddy field combination method was used to measure the water requirement of rice in 1983. First in Quanzhou station for pilot, after Longyan, Ningde station to carry out collaboration; In addition, Quanzhou station also using pit combination of law, pit test, tube test at the same time rice water demand test carried out
