江苏省仪征市中后山区小麦返青以后经常会大范围内出现麦苗发黄、分蘖少、脱力等黄僵苗现象,针对这一现状,设计了该试验,旨在探索不同施肥方式对僵苗转化及其产量的影响。试验结果表明:小麦返青期出现黄僵苗的田块补施肥料均有增产效果,其中尤以施用尿素加壮秧剂试验小区有效穗适宜,每穗粒数多,千粒重高,增产幅度最大,平均亩单产达433kg,比空白区增产17.7%。
Yizheng City, Jiangsu Province, the mountains after the mountain green wheat often appear within a wide range of yellowing, tillering less, off yellow Huangmiao phenomena such as the phenomenon, this study designed to explore the different modes of fertilization on the transformation of stiff seedlings And its impact on output. The results showed that the field supplemented fertilizer with Huangjianmiao had the effect of increasing production in wheat rejuvenation period, especially the effective panicle in the trial plot with urea plus strong seedling agent, with more grains per panicle, heavier grain weight and the largest yield increase, The average yield per mu reached 433kg, 17.7% more than the blank area.
