山西省屯留县王公庄村地处上党盆地,十年九旱,年均降雨量500毫米左右,四季分布极不均匀,冬春干旱,夏秋多雨。1979年以来,我们通过多年试验研究,从投入适宜的机械化技术入手,逐步形成了一整套旱作玉米机械化高产栽培技术。全村2500亩玉米亩产由268公斤提高到约700公斤左右,1985年亩产最高达到745公斤,即使在1986年持续干旱、年均降雨量仅311.8
Wangjiazhuang Village, Tunliu County, Shanxi Province is located in the Shangdang Basin. It has an average annual rainfall of about 500 millimeters with an extremely uneven distribution of the four seasons. It is arid and winter drought and summer and autumn rainy. Since 1979, through years of experimental research, we have started to put in place suitable mechanized technologies and gradually formed a set of mechanized high-yielding cultivation techniques for dry-cultivated corn. The village of 2,500 acres of corn per mu increased from 268 kilograms to about 700 kilograms in 1985 per mu up to 745 kilograms, even in 1986 continued drought, the average annual rainfall of only 311.8
