摘　　要：以晋黍9号为研究对象,设置了4个不同的中耕次数,分析其对黍子的农艺性状、叶面积指数、产量及对土壤容重、孔隙度的影响。结果显示,中耕与不中耕相比,增加了黍子的株高、穗长、节数、穗质量、穗粒质量、千粒质量、叶面积指数及产量;减少了土壤容重,增大了土壤孔隙度;以中耕2次和中耕3次的效果最为明显。The paper analyzes the effects of different styles of intertillage on agronomic traits, leaf area index and yield of broomcorn millet and soil bulk density and porosity, taking Jinshu 9 as the study subject, and selecting four different intertillage styles. The results show that comparing with no intertillage, intertillage increases the height, ear length, pitch number, ear quality, ear grain quality, thousand kernel quality（TKW）, leaf area index and yield. In addition, intertillage can decrease the soil bulk density and increase the soil porosity.And the best effect is intertillage two and three times on broomcorn millet.
