中文摘要	田间试验系统地比较了新冬20/沈玉2002不同套种模式（522模式与952模式）及521模式下保麦10号/蠡玉35、保麦10号/登海3672、新冬20/蠡玉35的产量、叶面积指数、光合势及干物质积累等性状的差异。结果表明，522模式新冬20/沈玉2002周年产量（17838．2 kg·hm~(-2)）较952模式（16550．9 kg·hm~(-2)）增产7．8％，其中，冬小麦增产18．4％。521模式保麦10号/蠡玉35、保麦10号/登海3672、新冬20/蠡玉35周年产量为19905．0～20751．0 kg·hm~(-2)，其中，冬小麦产量为9740～10275 kg·hm~(-2)、夏玉米产量为9630～10211．0 kg·hm~(-2)；冬小麦孕穗期和开花期叶面积指数分别为6．0、5．0左右，返青至成熟的总光合势290．2～324．310~4·m~2·d·hm~(-2)；夏玉米生育期111 d，大喇叭口期至吐丝后20 d的叶面积指数均保持在4左右，生育期间总光合势233．1～257．510~4·m~2·d·hm~(-2)，冬小麦和玉米总光合势为523．3～581．8*10~4·m~2·d·hm~(-2)；总干物质量38569．1～40487．0 kg· hm~(-2)；冬小麦产量的边际效应为85．7％～112．9％。521模式比952模式大幅度增产，是小麦行数和边行数及边际产量增大的结果，并将夏玉米播期提至麦收前15 d左右，延长玉米生育期（达110 d左右），优化株行配置使玉米增产显著，实现全年超高产。521模式同时充分利用了冬小麦边际补偿效应和玉米时间补偿效应，较952模式易获得周年超高产。并对超高产栽培技术进行了讨论。
英文摘要	Under field conditions,two inter-planting patterns,522 patternand952 pattern,of Xindong20 and Shenyu2002 were compared,and Baomai10 and Liyu35,Baomai10 and Denghai3672,Xindong20 and Liyu35,were compared with521 inter-planting patternmainly for the yield,leaf area,photosynthetic potential and dry matter accu-mulation.The results showed that the annual yield was increased for the 522 pattern(17 838.2 kg·hm~(-2))of Xin-dong20 and Shenyu2002 by 7 .8%,as compared with the952 pattern(yield 16 550 .9 kg·hm~(-2)).For winter wheat, the yield increased by 18 .4%.The annualproduction of521 patternof Baomai10 and Liyu35,Baomai10 and Deng-hai3672,Xindong20 and Liyu35 were 19 905 .0~20 75 1 .0 kg·hm~(-2),while for winter wheat yield were 9 740~10 275 kg·hm~(-2),and corn yield were 9 630 kg·hm~(-2)~10 21 1 .0 kg·hm~(-2) .Leaf area index of winter wheat were 6 .0 and 5 .0 at booting and flowering stage,respectively .The photosynthetic potential ranged from 290 .2 10~4·m~2·d·hm~(-2) to 324 .3 10~4·m~2·d·hm~(-2) between turning green and mature stage .The growth stage of summer corn was 1 1 1 days,the leaf area index maintained at four from large bell stage to grain filling stage,while that of photosynthetic potential was 233 .1 10~4·m~2·d·hm~(-2)~257 .5 10~4·m~2·d·hm~(-2) .the total photosynthetic potential of wheat and corn was 523 .3 10~4· m~2·d·hm~(-2) and 581 .8 10~4·m~2·d·hm~(-2),respectively.Total dry matter was 38 569 .1 ~40 487 .0 kg·hm~(-2) . Marginal effect of winter-wheat yield was 85 .7%~1 12 .9%.521 pattern of winter-wheat was outperform than952 pat-ternbecause of it increased rows and boundary rows and boundary yield which led to marginal effect .Meanwhile,sum-mer corn was planted at fifteen days after before wheat harvest,therefore extending growth period to nearly 1 10 days .In conclusion,the521 patternhas advantages of marginal compensation and growth period extension over the 952 pat-tern.
