田间临时渠、埝的设置芦台农场的地块一般长一千四百公尺,宽九十公尺,每块面积约一百八十五亩,地块两边分别与固定的用水支渠和排水支渠平行。由于地块中高窪不平,故于播种后需修筑临时渠、埝,把地块间隔成畦。畦的面积大小因地势高窪和土壤含盐分的高低而不同,一般窪地,不平的土地,含盐量高的土地,则畦较小;高地,平坦的土地,含盐量低的土地,则畦较大。畦的面积越大,虽占地面积越少,但往往由于排水不良,灌溉水层深浅不一致,造成了缺苗减产。畦的面积越小,虽占地面积越多,但在实践中证明:适当的缩小畦的面积会提高增产的效果。因此一九五一年每畦的面积平均为六——十五亩,至一九五四年即逐渐缩小为三点七五亩(芦
Temporary Ditch in the Field, 埝 Setting The Lutai Farm plots are generally 1 400 meters long and 90 meters wide with an area of about 185mu each. Both sides of the block are connected to fixed water branch and drainage Branches parallel. Due to the high-lying uneven terrain, it is necessary to build a temporary channel after sowing, 埝, the plot interval 畦. Due to the high and low ground conditions and the salinity of the soil, the area of 畦 is different. In general, the depression, the uneven land and the land with high salt content are smaller. The highland, the flat land and the land with low salt content畦 larger.畦 the larger the area, although the smaller the area, but often due to poor drainage, irrigation water depth inconsistent, resulting in a lack of seedlings cut. The smaller the area of 畦, although the more area, but in practice proved that: the appropriate reduction of 畦 area will increase the yield effect. Therefore, the area of each shoal in 1951 averaged between 6 and 15 mu and gradually reduced to 3.57 mu in 1954 (as of
