修剪施肥对油茶叶绿素含量及光合速率的影响
Effect of Pruning and Fertilization on Chlorophyll Photosynthetic Rate of Camellia oleifera
摘要
Abstract
This paper studied the effect of pruning and fertilization on the growth and photosynthesis of Camellia oleifera taking juvenile forest as an objective in Tangwan town Jiangxi Province. The results showed that pruning increased the height of juvenile tree trunk and crown, and the transverse and vertical diameter of tree crown were promoted to a large extent. In addition, the growths of spring shoot, content of chlorophyll and photosynthesis rate were also increased by the treatment of shaping and pruning. The fertilization treatment of 3, 4, 5, 6, 7, 8 significantly promoted the growth of Camellia oleifera. The treatment of 1, 2, 6, 8, 9 accelerated the growth of spring shoot and the treatment of 7, 4, 1, 8, 9 apparently increased the content of chlorophyll in leaves. The photosynthesis rate increased with the increase of pruning intensity. Therefore, moderate pruning intensity in Spring and Summer combined with the control of crown form was effective to promote the growth of juvenile tree.关键词
