摘要: 为了筛选出适合兴安盟地区玉米高产高效的耕作模式,于2017年在扎赉特旗设置3个深松处理(30,40,50 cm)与浅旋(CK)处理进行试验。结果表明:深松处理对玉米生育时期没有明显影响;在玉米的生长发育期中深松处理的土壤含水量与对照相比有所提升,在降水较多的年份,深松处理的保墒效果更好、更加明显;深松处理能够有效降低土壤容重,增加土壤通透性能;深松处理的叶面积和干物质均大于浅旋(CK);深松处理的穗粒数、穗长、百粒重和单位面积产量均大于浅旋(CK),而秃尖长小于浅旋(CK)。在各处理中,深松30 cm和深松40 cm处理的单位面积产量显著大于对照(P<0.05)。从试验各项指标综合分析,深松30 cm处理的效果较好,增产效果较明显,建议在兴安盟地区推广深松30 cm耕作模式。

Abstract: In order to select a high-yield and high-efficiency cultivation model for maize in Xing An League,four treatments were set up in Zhalaite Banner in 2017,including three subsoiling depths (30,40,50 cm) and shallow rotation (CK) treatments.The results show that:Deep loosening treatment has no obvious effect on the maize growth period. Soil moisture content of the deep loosening treatment was higher than that of control during the maize growth and development period. The soil moisture conservation effect of the deep loosening treatment was better and more obvious in years with more precipitation.The soil bulk density can be effectively reduced and soil permeability can be increased by the deep loosening treatment.Leaf area and dry matter of the deep loosening treatment were higher than that of traditional agriculture. The number of grains per panicle,panicle length,100-grain weight and yield in the deep loosening treatment were higher than those in shallow-spinning treatment,while the length of the bald tip was lower than that in shallow-spinning treatment.Among all treatments,the yield of 30 cm deep pine and 40 cm deep pine was significantly higher than that of the control (P<0.05).According to the comprehensive analysis of various indexes in this experiment,the effect of 30 cm deep loosening treatment is the best,and its effect on increasing production is the most obvious.

Key words: Subsoiling treatment, Physical properties of soil, Maize yield
