武进、丹阳两县的麦豆稻种植方式,以往采用单条播,即在宽度为3.2尺的畦面上,种一条幅宽0.8～1尺的早熟矮秆元麦,麦行间空幅2.2～2.4尺,冬季深翻晒垡,4月初播种4～6行大豆,7月中旬左右收获后,栽种一季水稻.全年亩产粮食一般在1000～1600斤,年度间波动较大,产量低而不稳.为了更好地发挥该轮作制的持续增产作用,1978年以来,组织专业单位和公社农科站协作,在本地区进行多点试验,1981年增添三个百亩连片的中间试验,获得如下初步结果. Wujin, Danyang two counties of wheat and bean cultivation methods, the previous single-sowing, that is, a width of 3.2 feet in the face of a planted width of 0.8 to 1 foot early maturing dwarf wheat, empty space between wheat lines 2.2 ~ 2.4 feet in winter deep sunning 垡, early April sowing 4 to 6 rows of soybeans, around mid-July after harvest, planting a season of rice. The annual per-mu yield of food generally in the 1000 ~ 1600 jin, fluctuating between the larger, low-yield and not In order to give full play to the continuous production increasing effect of the rotation system, since 1978, the specialized units of organizations and the agricultural cooperatives of the commune have collaborated to carry out more experiments in the region. In 1981, three intermediate trials of 100 mu contiguous pieces were added, Obtain the following preliminary results.
