The Effect of Adding Willow Leaves on Photosynthesis and Fluorescence of Strawberry under Continuous Cropping

摘要：

　　The paper focuses on the photosynthetic physiological mechanism of relieving strawberry continuous cropping obstruction by adding different levels of willow leaves (0 g·kg-1,2.5 g·kg-1,5 g·kg -l,10 g·kg-1,20 g·kg-1) in strawberry continuous cropping soil.The results showed that the content of various components chlorophyll in continuous cropping strawberry leaves increased obviously.At the same time,other photosynthetic physiological parameters Pn,Gs and Ci went up,too.According to this research,the treatment with willow leaves 5 g· kg-1 showed a better improvement than other treatments.All above proved that adding willow leaves could increase the activities of PS Ⅰ and PS Ⅱ in continuous cropping strawberry leaves.However,when increasing the mass ratio of willow leaves to a fixed level,the improvement of Photosystem function didnt increase as well.The conclusion is that adding willow leaves in continuous cropping strawberry soil had a definite function to reduce the continuous cropping obstacles of strawberry.Treatment Ⅱwith mass ratio 5 g·kg-1 had the best defense effect to the damage of photosystem in strawberry leaves.
