摘要: 【目的】探究耕作方式优化对内蒙古西辽河平原褐土土壤物理性质及谷子产量的影响。【方法】以传统浅耕30 cm(CK)作为对照,设置深耕机翻耕50 cm(SF)、深松机松耕50 cm(SS)、深松机松耕50 cm后旋耕机旋耕30 cm(SSX)、深耕机翻耕50 cm后旋耕机旋耕30 cm(SFX)4种处理,对比分析不同生育期不同处理对0~100 cm褐土层的土壤硬度、土壤容重、土壤含水率以及谷子产量的影响。【结果】不同耕作方式均改善了土壤结构,在0~10、10~20、20~40、40~60、60~80 cm土层,SS、SSX、SFX、SF处理的土壤容重较CK分别显著减小了0.16%~2.26%、4.63%~6.24%、3.81%~5.88%和1.08%~3.95%(P<0.05);在0~100 cm土层中均以20~40 cm土层的土壤含水率最高,各处理在不同生育期的土壤含水率均为SSX>SFX>SF>SS>CK,其中,SSX处理的土壤含水率较CK增加了4.81%~9.90%。在谷子农艺性状和产量方面,SSX、SFX处理的穗粗、穗长、穗重、千粒重较CK分别显著提高11.67%、9.28%、8.25%、10.98%和9.63%、7.70%、6.04%、8.63%(P<0.05);SSX处理谷子产量较CK提升最显著,为7.65%(P<0.05);各生育期谷子耗水量均表现为CK>SS>SF>SFX>SSX,SSX处理的谷子耗水量为893.60 mm;4种处理下,谷子水分利用效率均有所提高,以SSX处理效果最佳,较CK提高了8.14%。【结论】耕作方式优化可明显改善土壤结构、提升耕层土壤水分、增加谷子产量,尤以深松机松耕50 cm后旋耕机旋耕30 cm处理效果最佳,是缓解内蒙古西辽河平原褐土土壤障碍、保证谷子稳产增产的较优模式。

Abstract: 【Objective】To explore the effects of tillage methods optimization on the physical properties and foxtail millet yield of brown soil in the western Liaohe Plain,Inner Mongolia.【Methods】Using the traditional shallow tillage of 30 cm(CK) as a control,setting deep tiller tillage 50 cm(SF),deep loosening machine loosening tillage 50 cm(SS),deep loosening machine loosening tillage 50 cm and rotary tiller rotary tillage 30 cm(SSX),and deep tiller tillage 50 cm and rotary tiller rotary tillage 30 cm(SFX) four treatments,on soil hardness,soil bulk density,soil moisture content,and foxtail millet yield of 0-100 brown soils were compared and analyzed in different treatments and different growth stages.【Results】The soil structure was improved by different tillage methods,and the soil bulk density of SS,SSX,SFX,and SF treatments significantly decreased by 0.16%-2.26%,4.63%-6.24%,3.81%-5.88%,and 1.08%-3.95% compared with CK in 0-10,10-20,20-40,40-60,and 60-80 cm soil layers,respectively(P<0.05);the soil moisture content of 20-40 cm soil layer was the highest in the 0-100 cm soil layer,and the soil moisture content of each treatment was SSX>SFX>SF>SS>CK at different growth stages,and the soil moisture content of SSX treatment increased by 4.81%-9.90% compared with CK.In terms of agronomic traits and yield of foxtail millet,the ear thickness,ear length,ear weight and 1 000-grain weight of SSX and SFX treatments were significantly increased by 11.67%,9.28%,8.25%,10.98% and 9.63%,7.70%,6.04%,8.63%,respectively(P<0.05),and the yield of foxtail millet after SSX treatment increased most significantly compared with CK,was 7.65%(P<0.05);the water consumption of foxtail millet in all growth stages was CK>SS>SF>SFX>SSX,and the water consumption of foxtail millet under SSX treatment was 893.60 mm,and the water use efficiency of foxtail millet was improved under four treatments,and the effect of SSX treatment was best,which was improved 8.14% than CK.【Conclusion】The tillage methods optimization can significantly improve soil structure,increase soil moisture in tillage layer,and increase foxtail millet yield,the treatment of deep loosening machine loosening tillage 50 cm and rotary tiller rotary tillage 30 cm has the best effect,which is the optimal mode to alleviate the soil barrier of brown soil in the western Liaohe Plain,Inner Mongolia,and ensure stable and increased yield of foxtail millet.
