摘要:

为明确大兴安岭沿麓黑土区秸秆还田条件下不同耕作方式对土壤水分动态变化规律及玉米产量的影响,基于连续6 a耕作定位试验,分析秸秆全量粉碎深翻还田(SCD)、秸秆全量粉碎深松浅翻还田(SSS)、秸秆全量粉碎深松还田(SCS)、秸秆全量粉碎重耙还田(SCR)、秸秆全量粉碎旋耕还田(STR)、秸秆全量粉碎免耕还田(NTS)、秸秆不还田常规耕作(CK)7种耕作方式对2022年和2023年玉米不同生育时期0~60 cm土层土壤水分特征、耗水量、水分利用效率及玉米农艺性状和产量影响的差异。结果表明,2022年和2023年土壤质量含水率呈双峰型变化。0~10 cm土层土壤质量含水率显著高于CK,NTS处理在多个时期土壤质量含水率最高;10~20 cm土层中,SSS、NTS处理拔节期土壤质量含水率低于CK;20~40 cm和40~60 cm土层中,各处理土壤质量含水率较CK均有提升。2022年和2023年,不同生育期除NTS处理外,各处理玉米株高显著高于CK;成熟期SCD处理玉米株高最高,NTS处理最矮。各处理玉米苗期叶面积指数差异较小,拔节期后STR处理叶面积指数最大,大喇叭口期各处理叶面积指数均显著高于NTS处理。除SCS、NTS处理外,各处理干物质积累量均显著高于CK,成熟期SCD处理干物质积累量最高,NTS处理最低。与CK相比,各处理均可提高玉米产量和水分利用效率,但SCD处理显著高于CK。综合各指标分析,大兴安岭沿麓黑土区秸秆全量粉碎深翻还田和秸秆全量粉碎深松浅翻还田2种耕作方式有利于改善土壤结构、提升玉米产量和水分利用效率。

Abstract:

To clarify the effects of different tillage methods on soil moisture dynamics changes and maize yield under the condition of straw return to field in the black soil area along the foothills of Daxing'anling,based on six consecutive years of tillage positioning experiments,this study analyzed the effects of seven types of tillage methods,namely,full-crushing and deep-tillage (SCD),full-crushing and shallow-tillage (SSS),full-crushing and deep-tillage (SCS),full-crushing and re-harrowing (SCR),full-crushing and rotary tillage (STR),full-crushing and no-tillage (NTS),and conventional tillage without returning straw to the field (CK)on soil moisture characteristics,water consumption,water use efficiency,and agronomic traits and yield of maize in the 0—60 cm soil layer at different growth stages of maize in each treatment.The results showed a bimodal pattern of soil quality moisture content in 2022 and 2023.0—10 cm soil layer soil quality moisture content was significantly higher than that of CK,and the NTS treatment had the highest soil quality moisture content in several periods.10—20 cm soil layer soil quality moisture content was lower than that of CK in the SSS and NTS treatments at the jointing stage,and soil quality moisture content was higher than that of CK in the 20—40 cm and 40—60 cm soil layers in 2022 and 2023 for all the treatments.In 2022 and 2023,maize plant height in all treatments except NTS treatment was significantly higher than CK at different growth stages.The SCD treatment was the tallest and the NTS treatment was the shortest at mature stage.Leaf area index (LAI) varied little among treatments at seedling stage of maize,STR treatment had the highest LAI after the jointing stage,and all treatments had significantly higher LAI than NTS treatment at the big trumpet stage.Dry matter accumulation in all treatments except for the SCS,NTS treatment was significantly higher than in CK,and dry matter accumulation was highest in the SCD treatment and lowest in the NTS treatment at mature stage.All tillage treatments increased maize yield and water use efficiency compared with CK,but the SCD treatment was significantly higher than CK.Comprehensive analysis of the indexes showed that the two tillage methods of full-crushing and deep-tillage and full-crushing and shallow-tillage were favorable to improve soil structure,maize yield and water use efficiency in the black soil area along the foothills of Daxing'anling.
