摘  要：
研究在河套平原灌区开展定点试验,对比分析耕作方式与秸秆还田对玉米光合物质生产和产量的作用效果。结果表明:深松+翻耕+秸秆还田(SPR)、深松+翻耕(SP)、翻耕+秸秆还田(PR)、深松(S)、翻耕(P)均较浅旋(RT)能够显著提高玉米干物质积累量、叶面积指数、叶面积持续期、净同化速率、玉米产量。各处理间影响力表现为:SPR>SP>PR>S>P>RT。其中,SPR处理影响效果最显著,较RT干物质积累量最高增加45.52%,叶面积指数最多增加55.80%,叶面积持续期延迟,净同化率增加,玉米产量增加23.15%。

摘  要：
The experiment was carried out in Hetao plain irrigation area, and the effects of tillage and straw returning on photosynthetic material production and yield were compared. The results showed that subsoiling + plowing + straw returning to field(SPR), subsoiling + plowing(SP),plowing + straw returning to field(PR), subsoiling(S)and plowing(P)were all better than shallow rotary(RT),which could significantly increase the dry matter accumulation, leaf area index, leaf area duration, net assimilation rate and maize yield. The impact of each treatment were as follows: SPR>SP>PR>S>P>RT. Among them, the effect of SPR treatment was the most significant, the dry matter accumulation SPR treatment than RT increased by 45.52%, leaf area index increased by 50.80%, leaf area duration increased by 33.87%, net assimilation rate increased,corn yield increased by 23.15%.
