一概况武汉市郊有冷浸田及冬泡田共约74万亩,占总耕地面积三分之一。为了有效地改造这类低产田,找出经济可行的技术措施及治理方案,我所从1981年到1983年在四新农场做了农田地下排水田间试验。试区布置如图1所示。试验田面积18亩,分6块,每块3亩,其中一块为对比田;一块打鼠道;

An Overview Wuhan suburbs have about 740,000 mu of cold-sweeping fields and winter soaked fields, accounting for one-third of the total cultivated land area. In order to effectively reform such low-yield fields and identify economically viable technical measures and treatment options, I conducted a field drainage field test at Sixin Farm from 1981 to 1983. The test area layout is shown in Figure 1. The experimental plot covers an area of ​​18 acres and is divided into 6 blocks of 3 acres each, one of which is comparative field;
