| 摘 要： | 通过传统耕作、生物炭翻耕覆盖、地膜免耕覆盖、地膜翻耕覆盖、留茬覆盖和条带覆盖处理方式,分析不同耕作和覆盖方式对玉米长势及光合特性的影响。结果表明,地膜覆盖可通过提高地温明显缩短玉米出苗期,地膜翻耕和生物炭处理对玉米的生长均起到促进作用,影响期分别为苗期和拔节期。对比传统耕作,秸秆整秆覆盖和地膜覆盖在免耕条件下不利于植株生长。拔节期不同处理玉米净光合速率与气孔导度、蒸腾速率均呈正相关,生物炭处理净光合速率最高。

| Abstract: | The experiment analyzed the effects of maize growth and photosynthetic characteristics by the different tillage and mulching methods, such as the conventional tillage, the biological carbon over tillage, the plastic film mulching, turning over the soil with plastic film mulching, the straw stubble with straw mulching and the straw mulching. The result showed that the plastic film mulching could significantly shorten the emergence period of maize by increasing the soil temperature. Turning over the soil with plastic film mulching and the biological carbon over tillage could produce big cross crops, and the impact periods were seedling stage and jointing stage, respectively; contrast with conventional tillage, the straw mulching and the plastic film mulching were not conducive to maize growth when the land had not been turned on. Under different experimental treatments conditions, the net photosynthetic rate of maize, transpiration rate of maize and transpiration rate of maize were positively correlated during jointing stage. The net photosynthetic rate of biological carbon treatment was the best. |
