黄竹生物学特性的研究

本文对滇南地区广泛分布的重要竹种黄竹(Dendrocalamus membranaceus)的生物学特性进行了探讨,总结报道了其地理分布、生态习性、生长发育规律及生物量变化等方面的研究成果。研究表明:黄竹是一种热带北缘分布的阳性竹种,喜光而不耐荫蔽;7月上旬开始发笋,8月上旬为发笋盛期;9月为生长旺季,平均日高生长可达0.31m。

A STUDY ON THE BIOLOGICAL CHARACTERISTICS OF DENDROCALAMUS MEMBRANACEUS MUNRO

This paper reports the biological characteristics of the bamboo (Dendrocalamus membranaceus Munro) which is widely distributed in the South of Yunnan by summarizing its geogrophical distribution, ecological habits, growth and biomass. The observation shows that this bamboo is a heliophilous plant distributed in the northern edge of the tropies. It starts shooting in early July, shoots in larger quantities in August, and reaches it: climax in September. The average growth rate is 0.31 m. per day during the period.
