摘要

[目的

]

研究黑龙江省西部不同土壤耕作方式对玉米产量及土壤性状的影响，为该地区农业生产提供参考。[方法

]

比较常规耕作、旋耕、翻耕、深翻和超深翻耕作对玉米产量和土壤物理特性的影响。[结果

]

翻耕和超深翻耕作增加了土壤含水量和田间持水量，降低了耕层土壤渗透速率、土壤容重和土壤紧实度，但是增加犁底层土壤渗透速率、土壤容重和土壤紧实度。翻耕、深翻和超深翻处理耕层土壤三相结构距离（STPSD）和土壤结构指数（GSSI）较好；翻耕、深翻和超深翻处理显著降低犁底层土壤的GSSI，增加STPSD；旋耕处理没有显著影响犁底层土壤GSSI和STPSD。与常规耕作处理相比，翻耕和超深翻分别增加玉米产量7.6%和6.0%。翻耕比超深翻玉米产量高10.9%。深翻处理玉米产量为5.58 t/hm

，比常规耕作减产8.1%。[结论

]

在不完全打破犁底层情况下，在黑龙江西部地区翻耕是比较理想的耕作方式。

Abstract

[Objective] A field experiment was carried out to investigate the responds of maize yield and soil physical characters to different tillage managements in order to provide the scientific basis for agriculture production in the western part of Heilongjiang Province.[Methods] Five tillage strategies including rotary tillage

plowing

deep plowing

deep subsoiling and local conventional tillage were used.[Results] By plowing and deep subsoiling

soil water content and field water capacity increased in topsoil but decreased in plow bottom soil. Soil three phase structure distance (STPSD) and generalized soil structure index (GSSI) were preferable in plowing

deep plowing and deep subsoiling treatments

but poor in plow bottom soil. Both GSSI and STPSD were not affected by rotary tillage. Compared to local conventional tillage

plowing and deep subsoiling increased maize yield by 17.6% and 6.0%

respectively. Maize yield with plowing was 10.9% higher than that in deep subsoiling. The maize yield in deep plowing was 5.58 t/hm2

which was 8.1% lower than that in local conventional tillage.[Conclusion] Without soil breaking at plow bottom

plowing was the best tillage management in the aeolian sandy soil of Northeast China.
