田水管理是水稻栽培的一个重要技术环节,我县山区串灌不晒田的情况普遍存在,为摸索合理用水对水稻生长发育及产量的影响,我们于1975年做了早稻田水管理试验。一、试验概况:试验田面积0.5亩,对照区和处理区各为0.25亩,对照区长期串灌不烤田,处理区前期浅水灌溉,5月23日开始烤田,5月30日复水灌浆后干干湿湿,试验田为沙壤土,肥力中等,前作绿肥约亩施3000斤,生育期间亩施硫酸铵15斤,供试品种温选10号,3月23日播种,4月25 Field water management is one of the important technical aspects of rice cultivation. In our county, the phenomenon of string irrigation and non-drying is widespread. To explore the effect of rational water use on the growth and yield of rice, we conducted a trial of Waseda water management in 1975. First, the test profile: experimental plot area of ​​0.5 acres, the control area and the treatment area for each 0.25 acres, the control area long-term string irrigation does not bake field, treatment area early shallow irrigation, started May 23 grilled fields, May 30 rehydration grouting Wet and dry after the test, the experimental field of sandy loam soil, medium fertility, before the green manure about 3000 pounds of mu, 15 kg of ammonium sulfate during the development of test varieties temperature selection on the 10th, March 23 sowing, April 25
