大垄深耕整秆还田对郑单958生育性状及产量的影响

Effects of Straw Deep Returning with Double Lines Width Ridge on Growth and Yield of Compact Corn

以耐密玉米郑单958为试材,设24、18、12、6、0t/hm2(CK)的5种用量整秆深还,探讨了对耐密玉米的叶面积、叶绿素含量、单株干物重和产量影响。结果表明:12t/hm2处理的玉米叶面积、叶绿素含量、干物质积累高于对照和其他处理,产量最高达12 756kg/hm2。

Using the compact corn as the material, this trial set the dosage for returning crop stocks to the deep field with 24t/hm^2, 18t/hm^2,12t/hm^2 ,6t/hm^2 ,0t/hm^2 （CK） ,investigating its effect on compact corn with the leaf area, chlorophyll content, dry weight and yield of every plant. The results were as follows：The chlorophyll content, dry matter accumulation, leaf area of compact corn under the treatment with 12t/hm^2 were the others at the jointing, heading and grain filling among all the treatments. stages, and harvested a yield of 12 756kg/hm^2 highest compared to , which was the bestamong all the treatments.
