摘要: 为了揭示施肥对毛竹Phyllostachys pubescens林冠结构和光合能力的影响规律，研究了不同施肥处理下3年生毛竹从展叶到绿叶期的叶片大小、质量、分布状态和光合特性。结果表明：毛竹单叶面积、千叶质量和叶片分布受施肥的影响较小，是较为稳定的指标；展叶期施肥处理（处理1）能显著增加单株立竹的叶片数量，到7月底，其单株立竹叶片总质量和叶面积指数分别比绿叶期施肥（处理2）提高14.8％和13.7％，比不施肥（对照）提高27.6％和24.5％；冠层14 ～ 17档是单枝叶片数量最多的区域，施肥能增加各枝盘叶片的质量，但对林冠重心的分布无影响；单叶叶面积稳定后（6月），处理1的叶绿素测定值和光合速率显著高于处理2和对照，而处理2与对照间无显著差异。展叶期施肥通过叶片数量、叶面积指数和光合捕光色素含量的提高，增强了毛竹林光合能力。因此，建议在实际生产中于毛竹展叶期进行土壤养分补充。图6表1参16

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.］
