夜间模拟增温对冬小麦生长及产量的影响
Effect of nighttime warming on growth and yield of winter wheat
本试验拟以冬小麦为研究对象,采用被动式夜间增温方式研究夜间增温及叠加免耕条件下对冬小麦生长的影响,实验设置四种处理:常温+翻耕(CK)、夜间增温+翻耕(W)、常温+免耕(NT)、夜间增温+免耕(WNT)。W处理下,冬小麦株高,生物量,光合速率、叶面积产量构成因素中千粒重,每平米穗数以及产量都有一定程度的提高,其中产量增幅达24%;NT处理下,株高,生物量、光合速率、叶面积,产量构成以及产量在全生育期相比于CK都有显著的增加;WNT处理下各项生理指标和产量构成以及产量都有大幅度的增加,其增长幅度大于W和NT的单一处理,冬小麦产量增幅达53%。综上表明,在未来气候变暖的背景下采用免耕处理将有利于农作物生长。
The purpose of this experiment was to taking winter wheat as the research object, the influence on growth of winter wheat using passive Nighttime Warming mode study of Nighttime Warming and superposition under the condition of no tillage, The experiment setup four processing: 1) no warming with traditional tillage (CK), 2) nighttime warming with traditional tillage (W), 3) no warming with no-tillage (NT), and 4) nighttime warming with no-tillage (WNT). Under W, winter wheat plant height, biomass, photosynthetic rate, leaf area and yield components in 1000 grain weight, panicle number and yield per square meter, have a certain degree of improvement, which yield an increase of 24%; Under NT treatment, plant height, biomass, photosynthetic rate, leaf area, yield and structure the yield in the whole growth period compared to CK have increased significantly; Under WNT treatment,physiological indices, yield components and yield have substantially increased, its growth rate is greater than W and NT, the yield of winter wheat increased of 53%. These show that the use of no tillage treatment in future climate warming will be conducive to the growth of crops.
