Abstract

Through pot experiment with single factor randomized block design，this paper studied the effect of fertilization in different times on canopy development and photosynthesis of Phyllostachys pubescens，the size，weight，and distribution of leaves as well as their photosynthetic characteristics from leaf-expansion to maturity were studied. Treatments were as follows：fertilization during leaf-expansion period，fertilization during green-leaf period，and no fertilizer（ck）. Results showed that individual leaf area，thousand-leaf weight，and leaf distribution were relatively stable with little influence from fertilization. Fertilization during leaf-expansion compared to the green leaf period significantly increased leaf number，leaf weight per plant，and leaf area index. Fertilization during leaf-expansion also significantly increased the total weight of leaves corresponding to each branch. The 14th to the 17th branches had the largest number of leaves in the canopy with fertilization increasing the weight of each branch but not changing the center of the canopy. After June when individual leaf area was stable，chlorophyll concentration（SPAD value） and the photosynthesis rate of the leaf per unit area during leaf-expansion were significantly higher than the green leaf period and ck. Thus，for production，the bamboo forest should be fertilized in the leaf-expansion period. ［Ch，6 fig. 1 tab. 16 ref.］
