| 摘 要： | 在大田条件下,研究了常规、覆膜、覆草不同种植模式、不同氮素水平对玉米幼苗某些生理特性及产量的影响。结果表明,不同种植模式明显影响了幼苗干物质的积累,无论施肥与否,覆膜种植模式下,玉米生物量最高。生理指标测定结果显示,覆膜种植叶片叶绿素含量最高,光合速率最高,但蒸腾速率最小。叶片耐脱水力测定结果表明,叶片耐脱水力均随施肥量的增加而增强;在相同氮素水平下,覆膜种植的叶片耐脱水力最强,其次是覆草,而常规种植最弱。不论施肥与否,覆膜种植条件下玉米产量最高,其次是覆草,常规种植产量最低。

| Abstract: | A field experiment was carried out on cultivated loessial soil in semiarid areas. The corn(Zea mays L) Shaandan 902 used as a indicating crop to study the effect of plastic muchling, straw mulching and traditional culture on the physiological charicteristucs. The results showed that plastic film mulching significatly increaseed the photosynthesis rate, the content of chlorophyll and water capacity of leaf, but the transpiration rate decreased. Du to the reasons listed above, the accumulation of dry matter was greater in plastic film mulching, and after harversting,the yield was also greater than others. |
