摘要:
“九五”期间，我们以充分发挥沟谷地的生态资源优势和育壮苗、攻大穗、增粒重的玉米高产规律为结合点，研究与明确了沟谷地高产玉米的生理机制，组建了以秋耕起垄顶凌覆膜保墒、选用紧凑型“三大”玉米品种、施足底肥重攻拔节肥、中后期洪淤补灌等四项技术为核心的沟谷地玉米生态抗逆高产栽培技术体系，制定了针对性强、技术准确、便于操作、简单易行的规范化技术.经大旱的1999年在河沟流域沟谷地大面积示范，18hm2沟谷地玉米平均单产8142.0kg/hm2，接近历史最高年，较临近的沟谷
Abstract:
Physiological mechanism of high yielding corn in the ravined valley was studied.Based on the results,the technical regime of ecologically adverse resistant and high yielding cultivation for the corn in the ravined gully has been constructed.The major detailed techniques for the regime are ridging-ploughing in autumn and film-mulching during the thawing time in spring,adopting compact corn varieties with big ears and grains and adequately long growing stage,fertilizing adequately at seedtime and at jointing stage and irrigating with floodwater in the middle and late.The standardized techniques have also been established.In the exemplary trial in the drought year of 1999,the average yield of corn on 18 hm2 of ravined valley reached up to 8 142.0 kg/hm2,which was close to the highest record in the past years and had an advantage of 3 750 kg/hm2 over the control.Some fields yielded up to 12 600 kg/hm2.Production practice showed that the technical regime is a breakthrough measure to realize the high yielding or super-high yielding aim.
