摘要
为了解不同播种方式下土壤生态环境及小麦产量的变化，以河南农业大学提供的小麦品种超力1号为试验材料，对2种播种方式（平播、免耕秸秆覆盖沟播）下土壤温度、水分、小麦叶片SPAD值及产量进行测定和研究。结果表明，沟播条件下，冬季0～5cm耕层地温较平播高约1～2．2℃。沟播土壤踏实，水分下渗后不易散失，保水能力强；平播麦田的土壤疏松，表层水分容易散失，而且下渗也快，水分不易保存。2种播种方式都能使旗叶保持较高的绿色持续期。沟播产量大于直播，增产幅度约8.4%。
In order to study the changes of different planting ways on the soil ecological environment and wheat Physiological characteristic, soil temperature, water, wheat physiological characteristic and yield under different planting ways were studied. The results showed the topsoil temperature of 0～5 cm furrow planting is 1～2.2℃ higher than that of flat planting. The soil of furrow planting is solid, water is not easy to disappear after it infiltrates, so furrow planting guarantees water ability; The soil of flat planting is loose and surface water is easy to disappear and infiltrate quickly,so flat planting is not easy to guarantee water ability; Two planting ways all can make flag leaves maintain high green duration; yield of furrow panting is more than that of flat planting,and increase about 8.4%.
