参照玉米等中耕作物的管理措施,把小麦移植的效果转移到一般麦田进行小麦断根试验。1974～1975年用“农大139”品种,高肥稀植田(12.9万苗)观察不同时期深断根(3寸)在主要性状上的反映;1975～1976年在一般麦田,基本苗24万,分冬前断、返青断.起身断、拔节断、冬前返青、冬前起身、返青起身、对照八个处理。断根都是深3寸,在麦垄两侧断;1976～1977年在一般麦田,基本苗26万,由3月21日起每5天断根一区,到4月10日共7个处理,大小垄种植方式,大行距20厘米,小行距10厘米,在大行距内断根深3寸,小垄不断:
With reference to the management measures of maize and other mid-tillage crops, the effect of wheat transplanting was transferred to the wheat field for wheat root cutting test. From 1974 to 1975, the main characters of deep-rooted (3-inch) in different periods were observed with “Nongda 139” variety and high-fertility sparsely-cropped field (129,000 seedlings); from 1975 to 1976 in the general wheat field, the basic seedling was 240,000 Before the winter off, turn green off.From off, pull off, turn green before winter, get up before winter, turn up youth, control eight treatment. Broken roots are deep 3 inches, off both sides of the wheat ridge off; 1976 to 1977 in the general wheat field, the basic seed 260,000, from March 21 onwards every 5 days a root zone until April 10 a total of seven treatment, The size of the ridge planting way, big row spacing 20 cm, small row spacing 10 cm, in the big row of broken roots 3 inches deep, small ridge constantly:
