为了经济用水和制定较精确的作物灌溉制度,我们采用筒测法作了高粱、洋芋、甜菜在地下水位1.0—1.1米、地下水矿化度小于4.28克/升的砂壤土上,利用地下水量的试验.初步结果如下:(1)高梁六月十二日播种,九月廿五日收获,全生长期105天.共灌水四次,溉灌定额125公方/亩.有效降水21.7公方/亩,利用地下水241公方/亩,总耗水量387.7公方/亩,其中叶
In order to use water economically and develop a more precise irrigation system for crops, we used barrel testing to make sorghum, potato and sugar beet on sandy loam with groundwater level of 1.0-1.1 m and groundwater salinity of less than 4.28 g / The preliminary results are as follows: (1) The sorghum was sown on June 12 and harvested on September 25, the full-growth period was 105 days, a total of four irrigation days were carried out, the irrigation irrigation quota was 125 km 2 / mu, the effective precipitation was 21.7 km 2 / Mu, using 241 square meters of groundwater per mu, total water consumption of 387.7 square meters / mu, of which leaves
