摘要

人工模拟降雨条件下

在大田设置地膜覆盖(PM)、4种秸秆覆盖量(覆盖量分别为1 500

4 500

7 500

10 500kg/hm2

即SM15、SM45、SM75和SM105)

同时设置无覆盖处理作为对照(CK)

研究不同覆盖方式对雨后冬小麦棵间蒸发量、土壤剖面水分和降雨土壤蓄积量的影响。结果表明:各处理雨后冬小麦逐日棵间土壤蒸发累积量和日变化有相同变化趋势;同一时间段内不同覆盖处理的土壤蒸发差异明显

各生育阶段土壤累积蒸发量和日蒸发量均表现为SM105SM75>SM45>SM15>CK>PM;受植株冠层降雨截留量增大的影响

冬小麦拔节期后各处理的土壤含水量和降雨土壤蓄积量明显低于拔节期前的。研究结果可为提高冬小...

Abstract

By setting plastic mulching(PM)

1 500

4 500

7 500

and 10 500 kg/hm2 of straw mulching quantiy respectively(SM15

SM45

SM75 and SM105)

also setting no mulching as control treatment(CK) in winter wheat field

under simulated rainfall situation

the influence of different covering methods on soil evaporation

soil moisture and rainfall storage by soil were studied.The results indicated that the daily variations and daily cumulative of soil evaporation had the same trend in all treatments;the difference of soil eva...
