| 摘 要： | 研究了多雨年间不同熟期品种四密25与郑单958在覆膜条件下干物质积累与分配及产量的关系。结果表明:覆膜条件下干物质积累高于露地条件下干物质积累;品种间茎、叶、鞘等玉米器官干物质转移量与转移率存在差异,转移率四密25>郑单958,转移量郑单958>四密25;覆膜条件下玉米产量高于露地栽培产量,而且郑单958>四密25。中熟品种产量受覆膜影响小,晚熟品种覆膜增产潜力大。 |
| 关 键 词： | 玉米 寒地覆膜 干物质积累 产量 |

| Abstract: | Two maize varieties with different growth durations were studied under conditions with different cultivation techniques in rainy year.The results indicated that the polythene mulching could improve the yield and dry matter accumulation.The transfer rate and the transfer quantity were different in different organs between different varieties.The transfer rate of Simi25 was higher than that of Zhengdan958.The transfer quantity of Zhengdan958 was higher than that of Simi25.There was a little effect on the yield of medium variety in the condition of polythene mulching.The yield potential of late variety was high in the condition of polythene mulching. |
| Keywords: | Maize Polythene mulching in cold region Dry matter accumulation Yield |
