各种免耕制中，小麦茬后玉米产量的降低推动了耕作和残茬管理对玉米生长和苗床环境影响的研究。在２种耕作水平下（秋深翻ＭＰ和免耕ＮＴ），评价了４种小麦残茬管理方式（残茬移掉、收后秸秆打捆、秸秆盖在地面、秸秆覆盖地面并在秋季加施５０ｋｇＮ／ｈｍ２）。各免耕处理要获得５０％的玉米出苗率和５０％的抽丝率需多出２ｄ以上的天数，播后５和７ｗｋ的生物量最低。而ＭＰ各处理的籽粒产量相近，均比免耕处理产量高１．１ｔ／ｈｍ２以上。免耕区残茬移掉的处理使５０％玉米出苗率的天数减少，秸秆打捆和不打捆处理的玉米产量增加０．４３ｔ／ｈｍ２和０．６１ｔ／ｈｍ２，但仍比ＭＰ处理产量低８％。ＭＰ处理间产量差异与秋季地面积留小麦残茬最或施Ｎ量呈显著相关。在生长前期，留茬的免耕处理较ＭＰ（打捆）处理土壤度天数（ＧＤＤ）少，而１５ｃｍ表土含水量则高于其它处理，免耕小区秋季施５０ｋｇＮ／ｈｍ２既不影响土表小麦残茬量，又不影响播种时土壤ＮＯ３－Ｎ水平。
In all kinds of no-tillage, the reduction of corn yield after the wheat stub promoted the research on the effects of tillage and stubble management on the growth of maize and seedbed environment. Four kinds of wheat stubble management methods were evaluated under two tillage levels (Qiu Shen Tiao MP and no-tillage NT) (stubble removed, straw tied after harvest, stalks covered on the ground, straw covered on the ground and added in autumn Shi 50kgN / hm2). No tillage treatment to get 50% of the corn emergence rate and 50% of the spinning rate to be more than 2d the number of days after sowing 5 and 7wk the lowest biomass. The output of MP in each treatment was similar, which was 1.1t / hm2 higher than the no-tillage treatment. The removal of stubble in the no-tillage area reduced the number of days for emergence of 50% maize and increased 0.43 t / hm2 and 0.61 t / hm2 for maize baling and un-bundling, but still lower than those for MP 8%. The difference in yield between MP treatments was significantly related to the amount of N residual or N application in wheat in autumn. In the early stage of growth, stubble no-tillage treatments had less days (MPD) than GD (GD), while 15 cm of surface soil moisture content was higher than other treatments. No-tillage plot application of 50 kg N / hm2 in autumn did not affect soil surface wheat The amount of stubble does not affect soil NO3-N level at planting.
