- 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.
