以一家一户为生产单位,三麦生产的不平衡性相对增大了。历年有20%左右面积的三类苗,亩产比全县均产低20～35%,极大地影响了三麦的平衡增产。三类苗的发生与存在;早期难以诊断出来,往往在拔节后矛盾激化才被人们重视,此时实施转化措施只能事倍功半。近几年实践结果,冬前进行早期诊断转化的,比春后实施转化的亩增产20～25%,部分田块甚
With one household as a production unit, the imbalance in the production of Sanmai has relatively increased. Over the years there are about 20% of the area of three types of seedlings, mu yield lower than the county average 20 to 35%, greatly affected the balance of three wheat production. The emergence and existence of three types of seedlings; early diagnosis difficult to come out, often after the conflict intensified jointing was taken seriously, then the implementation of conversion measures can only be more effective. In recent years, the results of practice, early winter before the diagnosis and transformation, transformation than the implementation of the spring acre 20-20% yield increase, some fields
