间作紫云英对退化土壤中猕猴桃生长的影响

Effect of Milk Vetch Intercropping on Growth of Kiwifruit in Degraded Soil

  • 摘要: 为研究间作绿肥对退化土壤中猕猴桃生长的影响,试验以东红猕猴桃为材料,研究了间作紫云英后退化土壤中猕猴桃成活率、茎叶生长情况以及叶绿素含量变化等。结果发现,与对照组相比,紫云英间作的试验组猕猴桃长势良好,株高、株径、叶片数、叶面积和单叶重均显著提高,但叶绿素含量并未发生明显改变。此外,间作紫云英后猕猴桃光系统Ⅱ(Photosystems,PSⅡ)实际光合效率和光合电子传递速率有所提高,但效果不明显。表明间作紫云英能够有效促进退化土壤中猕猴桃的生长。

     

    Abstract: Effect of intercropping vegetation with target plants on remedying a degraded plantation was studied. The Donghong kiwifruit plants were interplanted with milk vetch in this experiment to determine the survival rate, stem and leaf growth and chlorophyll content of the plants on a land with degraded soil. The results showed that the kiwifruit plants grew better with interplanted milk vetch. A significantly increased height, girth, leaf count, area and weight of the plants were observed in comparison to those without the intercropping. There was no significant difference on the chlorophyll content. And, the efficiency and electron transport rate of the plant photosynthesis increased slightly but not significantly. It appeared that the growth of kiwifruit in a degraded soil could be improved by intercropping with milk vetch in the field.
