多年来,我县种小麦一般都是2丈1畦,畦边挖一条1.4尺宽水沟(墒),水沟(墒)两边各距小麦行留5寸空地(见图),这样两畦小麦边行的距离为2.4尺。多年来这2.4尺的空地一直休闲。有人曾试验在水沟边种麦,结果降低了灌排的作用。我们于1978年秋播在大东公社嵇码大队试验在水沟边上面栽油菜,每边栽1行。实践证明,这样做不影响水沟的灌排效能。开始有人害怕会影响小麦生长,为此我们进行了认真观察。周庄生产队60亩泰山1号小麦田,25条水沟(墒),共栽油菜50行,株距均5寸。1978年10月7日播种小 Over the years, I County wheat is generally 2 Zhang 1 畦, 畦 dig a 1.4-foot wide ditch (soil moisture), ditch (soil moisture) on both sides of the wheat to stay 5-inch open space (see photo), so that two 畦The distance of wheat is 2.4 feet. Over the years this 2.4-foot open space has been casual. Some people have experimentally planted wheat on the gully, resulting in a reduction of irrigation and drainage. In the autumn of 1978, we broadcast a trial of rape at the Dadong Commune by a code brigade on the edge of the ditch. Practice has proved that doing so does not affect irrigation and drainage ditch efficiency. At first, some people were afraid that it would affect the growth of wheat. To this end, we made a careful observation. Zhouzhuang production team 60 acres of Taishan No. 1 wheat field, 25 ditches (soil moisture), a total of 50 rows rape, spacing are 5 inches.
