辽阳市位于辽宁中部,无霜期160天左右,全年活动积温3508℃,属一季有余两季不足农业区.为探索两茬栽培高产途径,我们于1990年进行了小麦下茬复栽玉米的试验,取得了两茬合计1107.8公斤的结果(其中玉米亩产859.8公斤).1991年全市7个乡镇示范21.9亩,两茬平均亩产1050.65公斤.现将复栽玉米高产栽培技术简介如下:
Liaoyang City is located in central Liaoning, frost-free period of about 160 days, annual accumulated temperature of 3508 ℃, more than two quarters of the season are less than agricultural areas .In order to explore two crop cultivation of high yielding ways, we carried out in 1990, Obtained a total of 1107.8 kilograms of the two stubble results (of which 859.8 kilograms of corn per mu.) In 1991, the city’s seven townships demonstration 21.9 acres, two stubble average yield 1050.65 kilograms now planting high yield cultivation techniques of corn is as follows:
