Effects of Fertilization on Chlorophyll Content and Photosynthetic Physiology of Alnus Cremastogyne
In order to investigate the effect of fertilization on the seedling growth of Alnus Cremastogyne,using one year old seedling of Alnus Cremastogyne as research object,the orthogonal and combinative test with three factors (nitrogen fertilizer,phosphate fertilizer,potash fertilizer) was made,the indexes change of tree seedling total chlorophyll content,photosynthetic physiology were determined.Results showed that the effect of fertilization on the seedling total chlorophyll content,photosynthetic physiology of Alnus Cremastogyne were different,the optimum combination for total chlorophyll content increased,the photosynthetic rate was shown to be N:P 0 ~0.2:1 ~0.4.
