涿鹿县郭庄乡郭庄村,地处塞外,海拔高,热量少、昼夜温差大,全年无霜期150天左右,基本不能种植冬小麦。为了提高复种指数和扩种细粮,1984年秋季,这个村的27个科技示范户参加稻麦复播试验,共种冬小麦40亩。由于采取了地膜覆盖和化促、化控等高产配套技术,获得了平均亩产812.5斤的好收成。其主要栽培措施如下:
Guo Zhuang Zhuolu County Zhuolu village, located outside the plug, high altitude, less heat, temperature difference between day and night, the annual frost-free period of about 150 days, the basic can not be planted with winter wheat. In order to increase the multiple cropping index and expand the fine grain expansion, in autumn 1984, 27 scientific and technological model households in this village participated in the experiment of rice and wheat replanting, with a total of 40 mu of winter wheat. As a result of mulching and chemical fertilization, chemical control and other high-yielding supporting technology, access to a good yield of 812.5 kg per mu. The main cultivation measures are as follows:
