| Abstract: |
| This article analysis relativity of winter wheat growth mete ?grouting rate etc with weather-factor?water-gene?growth-impetus?output and structure factor of output in semi-wetness and semi-arid climate region on Loess Plateau of Longdong. The result shows: precipitation of growth-time have notability positive domino offect and factor of light and heat have notability bear domino offect to growth mete in springtime-growth phase of nutrition. After entering growth phase of procreation, infection of precipitation in growth-time to growth mete?output and grouting rate is gradually weaken. Factor of light and heat change positive domino offect from bear domino offect of prophase, especially, illumination shows very importance to anaphase growth and output fashion of winter wheat in eastern Gansu. But after entering growth phase of procreation, due to the infection of precipitation to light, the sluice of soil-reservoir in prophase is the mostly origin of water efficiency consume of winter wheat. |
