不同耕作措施下春小麦产量对温度变化的敏感性分析
Sensitivity analysis of spring wheat to variations in temperatures under different tillage measures
摘要
Abstract
In order to study the influences of temperature variations under different tillage conditions on yield of spring wheat ,a revised APSIM model was used .A simulation was implemented to analyze the yield of spring wheat by cultivation measures including conventional tillage & straw turnover (TS ) , no-till (NT ) , and no-tillage with mulch (NTS ) under nine variable conditions using lowest and highest temperatures as the independent variable factors .Then the surfer software was used to complete the sensitivity analysis .The result shows that under three different cultivation mea-sures ,yield rate of the spring wheat was more sensitive to the variations of the highest temperature .When the highest temperature rose ,yield rate showed a negative sensitivity .Under conventional tillage + straw returned and no-till cover tillage measures ,the average yield of spring wheat are respectively 2 268 .8 kg·hm-2 and 2 274 .0 kg·hm-2 ,signifi-cantly higher than the average yield of spring wheat 1 815 .4 kg·hm-2 of no-till tillage measures .Under traditional farm-ing + straw returned and no-till cover tillage measures ,wheat production seemed stable with the changes of tempera-tures .When the lowest and highest temperatures varied within a certain range ,wheat production under traditional farming+ straw returned and no-till cover condition was stable .关键词
