研究一个地区农作物需水量及相应的规律,不但能直接为灌溉管理,水利规划设计和灌溉预报服务。而且对于指导当地的农业生产,充分发挥水土资源的效益都有重要的意义。一九七八年我站开始对赣抚平原灌区水稻的需水量进行试验研究。通过多年的连续定点观测,取得了一些资料,现就本灌区的水稻田需水量及相应的需水规律提出一些粗浅的看法,供读者参考。一、泡田需水量泡田需水量主要指从开始翻耕沤田到插秧这段时间稻田所消耗的水量,包括使
Studying crop water demand and corresponding laws in a region can not only directly serve irrigation management, water conservancy planning and design and irrigation forecasting services. But also has important meanings for guiding the local agricultural production and giving full play to the benefits of water and soil resources. In 1978, I began to test the water requirement of paddy rice in the Gan-Ping plain irrigation area. Through many years of continuous observation and obtaining some information, we present some superficial opinions on the water requirement of paddy fields and the corresponding water requirement in this irrigation area for readers’ reference. First, the amount of water required to fry fields Bubble water demand mainly refers to the time from the beginning of transplanting Tian to transplanting rice water consumed during this period, including the
