据调查,河北、河南、山东等省大面积夏玉米产量达到了每667平方米600千克的较高水平,其中小块和大片的高产地块比比皆是。例如河南温县个体农户李国营种植的3335平方米夏玉米获得了前所未有的每667平方米700千克高产水平。又如河北曲周县的白寨、王庄等乡的数片高产示范田均获得了每667平方米产700千克左右的好收成,个别小块示范地甚至达到800千克的超高产水平。回顾2012年夏玉米生产季的全过程,可以清楚
According to the survey, the output of large-area summer maize in Hebei, Henan and Shandong provinces has reached a high level of 600 kg per 667 square meters, of which small plots and large-scale high-yield plots are commonplace. For example, the 3335-square-meter summer maize planted by Li Guoying, an individual farmer in Wen County, Henan province, achieved an unprecedented yield of 700kg per 667sqm. Another example is the number of high yielding demonstration townships such as Baizhai and Wangzhuang in Quzhou County of Quzhou County in Hebei Province have all achieved good yields of about 700 kg per 667 m2 and some ultra-high yield levels of even 800 kg have been demonstrated in some small plots. Recalling the entire summer 2012 summer corn production season, we can clearly
