Abstract

为探求西北半湿润地区不同覆盖方式对农田土壤水热和作物生长的定量影响,试验对比研究了平作不覆盖
( CK) 、秸秆覆盖平作种植( SM) 、地膜覆盖平作种植( PM) 和垄覆地膜沟覆秸秆( SPM) 4 种覆盖方式对夏玉米土壤
水分、温度、作物生长、产量和水分利用效率的影响。结果表明: 覆盖处理在各生育期内0 ~ 260 cm 土壤贮水量都显
著高于对照( P < 0. 05) ,夏玉米生育期0 ~ 30 cm 土层内平均温度表现为: PM > SPM > CK > SM( 其中15 cm 时土壤
温度CK > SPM) ,垄覆地膜沟覆秸秆能够有效地聚集降雨。夏玉米地上部生物量随生育进程的动态变化符合
Logistic 生长模型,SPM 处理地上部生物量理论值最大,快速累积期提前,最快累积速率较大,持续时间较长。SM、
PM 和SPM 处理2 年夏玉米产量平均值分别较CK 处理提高15. 4%、23. 3% 和28. 4% ( P < 0. 05) 。水分利用效率
分别较CK 处理提高10. 2%、31. 2%和28. 0%( P < 0. 05) ,各覆盖处理间差异不显著。综合分析,垄覆地膜沟覆秸
秆可明显改善农田土壤水热状况,增加干物质积累量,提高夏玉米产量和水分利用效率,是该研究中最适合本地的
覆盖栽培方式。

Other Abstract

The influence of different field mulching treatments on soil water content,soil temperature,
crop growth,final yield and water use efficiency was studied during the summer maize growing season in
the semi-humid region of Northwest China. The mulching treatments included the flat plot with straw
mulching ( SM) ,flat plot with plastic film mulching ( PM) ,ridge-furrow planting with film mulching
over ridge and wheat straw mulching over furrow ( SPM) ,and flat plot without mulching ( control
treatment,CK) . The results showed that water content of mulching treatments in soil layer of 0 ~ 260 cm
depth was significantly larger than that of CK during maize growing period ( P < 0. 05) . The average soil
temperature in the soil layer of 0 ~ 30 cm depth showed a decreasing trend of PM,SPM,CK and SM,
and the average soil temperature of CK was larger than that of SPM when the soil layer was 0 ~ 15 cm
depth. The development of maize aboveground biomass can match well with the logistic curve. Moreover,
the average yields of SM,PM and SPM in the two-year experiment were increased by 15. 4%,23. 3%
and 28. 4% compared with that of CK,respectively ( P < 0. 05) . The water use efficiencies of SM,PM
and SPM were increased by 10. 2%,31. 2% and 28. 0% compared with that of CK,respectively ( P <0. 05) . By comparison,the SPM can collect rainwater more effectively than other treatments and had the
largest aboveground biomass in theory. In the treatment of SPM,the rapid dry matter accumulation period
was earlier,and the cumulative rate was the fastest with a longer accumulation period,which meant that
the SPM can significantly improve the soil water-heat conditions,increase the accumulation amount of
crop dry matter,promote crop growth and improve water use efficiency. Therefore,the SPM was the
better choice for local farmers in the semi-humid region of Northwest China.
