黄淮区不同播种方式对玉米出苗质量和土壤环境的影响

Effects of Different Seeding Methods on the Soil Environment and Quality of Maize Germination in the Huang-Huai Plain

在黄淮平原小麦玉米两熟区,通过不同还田条件、播深和镇压3因素裂区试验,研究免耕条件下玉米出苗的土壤环境及出苗质量。结果表明,秸秆还田与不还田显著影响玉米出苗质量,表现为黄化、弱苗率差异显著;秸秆还田下播深对出苗质量有显著影响,镇压对出苗质量影响不显著。3因素交互效应对土壤环境影响程度依次是水分>硬度>温度。

The studies were conducted on the effect of different seeding methods on the seedling soil environment and quality of maize germination under the condition of no-furrow in wheat-corn cropping area of the Huang-Huai plain.The results showed that wheat stalk full returned to the fields or not significantly affected the quality of maize germination,especially etiolating seedling.Sowing depth significantly affected the quality of maize germination while compacting could not,which under the condition of the wheat stalk full returned to the fields.The effects order of the three factors which affect on the soil environment is moisture〉 rigidity〉temperature.
