中国农机院农机试验站位于北京市昌平区沙河镇小王庄与大洼村交界处。北京地区多数年份的春末夏初,少雨干旱,2000年更为严重。白天烈日当空,有时气温高达40℃,农村田里大部分庄稼呈现半枯萎状态。然而,中国农机院农机试验站田里的庄稼却碧绿茁壮,生机勃勃,长势喜人。为什么会出现这样的奇迹呢?当看到大型喷灌机在这里均匀地喷洒着“蒙蒙细雨”时,您就会找到答案。 China Agricultural Machinery Farm Experiment Station is located in Shaoyang Town, Changping District, Beijing Xiao Wang Zhuang and Dawa village junction. In the spring, early summer and early summer in most years in Beijing, there was less rainfall and more drought in 2000. During the day when the sun is hot and cold, and sometimes the temperature is as high as 40 ℃, most of the crops in the rural fields are semi-withered. However, the crop of the farm machinery pilot station at the China Academy of Agricultural Sciences is still robust and vigorous. Why do you see such a miracle? You will find the answer when you see a large sprinkler sprayed evenly here.
