扩大玉米的播种面积,对于粮食增产是有重要意义的。但是,只凭主观愿望,不根据当地的具体条件(土质、肥料、水利、种植经验以及气候条件等等),盲目的扩大玉米的种植面积,特别是在无霜期短,扩种晚熟品种的地区,造成严重减产,是完全可以想象的。因此,在扩种玉米时,必须深入了解,进行试种,等到摸出经验之后再进行扩大,是比较稳当的做法。本文曾就山西雁北地区盲目扩种玉米造成减产的原因,得出深刻的教训,作出综合的报导,可供各地农业生产者的参考。
Enlarging the sown area of corn is of great significance to the increase of grain output. However, we blindly expand the area planted with corn solely on the basis of subjective desire and without depending on local specific conditions (soil, fertilizers, water conservancy, planting experience and climatic conditions, etc.), especially in areas where the frost-free period is short and late-maturing varieties are expanded. It is perfectly conceivable that a serious cut in production will be caused. Therefore, when expanding corn, it is necessary to understand and carry out trial cultivation, and it is more appropriate to expand the trial after we have gained experience. This article has on Shanxi Yanbei blind expansion of corn caused by the reasons for the cut, draw lessons learned, make a comprehensive report for all local agricultural producers reference.
