我站在县委领导下,在县水利局党支部的支持下,去冬今春与当地贫下中农一起,对地下水位与春粮生产的关系作了一些试验,现将初步的结果简报如下:一、试验设计:选择一块北面有桑树地,南面有灌排分系渠道(明渠)的大麦田。田长54公尺,宽12公尺,面积0.97亩。田内分桑树地边、(土仑)沟和暗管三个区域。其中(土仑)沟区(3公尺—(土仑)—沟)分成40—40、40—80、80—60、60—60公分的等深沟和不等深沟四种处理;暗管处分两种处理,一是在12公尺宽的田中间埋设一条暗管,二是在田边上埋设一条暗管。各处理设有观测
I stood under the leadership of the county Party committee, with the support of the party branch of the County Water Conservancy Bureau, together with the poor and middle peasants in the winter and spring, made some experiments on the relationship between the groundwater level and the production of spring grains. The preliminary results are as follows: Experimental Design: Choose a barley field with mulberry fields in the north and channels for irrigation and drainage in the south (open channels). Field length of 54 meters, 12 meters wide, an area of 0.97 acres. Field mulberry ground points, (Tulun) ditch and underground pipe three areas. Among them, the (Tulun) ditch area (3 meters - (Tulun) - ditch) was divided into 40-40, 40-80, 80-60 and 60-60 cm isosceles and unequal ditches; Tube disposal in two ways, first, 12 meters wide in the middle of the field buried a dark tube, the second is buried in the edge of an open field tube. Each treatment is provided with observations
