中文摘要	为了进一步探索适宜山东省半湿润易干旱地区夏玉米高产、稳产的耕作措施,本试验研究小麦、玉米轮作下免耕、深松、深耕两季的耕作方式(7个)对夏玉米穗位叶片衰老特性、灌浆期干物质积累、转运及籽粒产量的影响。结果表明(定位试验第3年):小麦深松+玉米免耕直播+秸秆还田(W_3M_2)可显著提高夏玉米叶片生育后期SOD活性、叶片可溶性蛋白含量,而MDA含量增加缓慢,显著延缓穗位叶衰老;在吐丝至成熟期间干物质生产量上,W_4M_4(小麦深耕+玉米隔年深耕+秸秆还田)和W_1M_1(小麦旋耕+玉米隔年旋耕+秸秆还田)最高,W_3M_2和W_3M_3(小麦深松+玉米隔年深松+秸秆还田)次之,均显著高于CK和W_1M_2(小麦旋耕+玉米免耕直播+秸秆还田);W_3M_2干物质向籽粒运转比例即收获指数最高,W_4M_4最低;各耕作方式下W_3M_2和W_1M_1籽粒产量最高,分别比对照增加23.90%和9.87%。因此在本试验条件下小麦深松+玉米免耕直播+秸秆还田(W_3M_2)耕作方式下更有效延长叶片功能期,提高后期叶片生理活性,促进干物质向籽粒运转,增产效果显著。本研究可为华北麦-玉两熟农区合理安排周年耕作措施提供理论依据。
英文摘要	In order to explore the most suitable tillage managements to reach high and stable yield in summer maize in Shandong province,a semi-humid and drought-prone area of the North China,with the traditional tillage (rotary tillage at wheat season + direct seeding maize + no straw returning) as control,the effects of tillage managements (i. e. no tillage,subsoiling tillage,deep tillage) during wheat-maize whole season on the ear leaf senescence,accumulation and translocation of dry matter and grain yield of summer maize were studied. It was found that W_3M_2 (Sub soiling tillage at wheat season + Direct seeding at maize season + no straw returning) not only significantly increased SOD activity and soluble protein content of ear leaf,but also decreased the content of MAD and delayed the ear leaf senescence. Both W_4M_4 (Deep tillage at wheat season + Deep tillage at maize season + straw returning) and W_1M_1 (Rotary tillage in wheat season + Rotary tillage in apart maize season + straw returning) recorded the highest dry matter production and followed by W_3M_2 and W_3M_3 (Sub soiling tillage at wheat season + Sub soiling tillage at apart maize season + straw returning), while CK and W_1M_2 (No-tillage at wheat season + Direct seeding at maize season + straw returning) recorded the lowest value. The highest and lowest allocation proportion of dry matter to grain (harvest index) was recorded in W_3M_2 and W_4M_4, respectively. The grain yield of W_3M_2 and W_1M_1 were the highest,with the increase of 23.90% and 9.87% compared with CK respectively. In the whole,W_3M_2 could effectively maintain physiological function of leaf,even at late grain filling stage,and accelerate the allocation of dry matter to grain,which causes a significant increase in grain yield. The results would give some suggestion for adopting an appropriate tillage and residue management for the two rotation cycle of wheat - maize system in North China.
