摘要: 在福建省永安市上坪乡龙共村设立5个毛竹纯林样地,从2001—2005年连续5a观察不同年份晚秋、冬季降雨量对冬笋生产量、个体数量、形态发育以及经营效益的影响。结果表明:晚秋、冬季降雨量在70mm以下,冬笋的个体都较小,形态偏向鼠嘴型,产量低;晚秋、冬季降雨量大于200mm,冬笋的个体发育好,形态上鼠嘴型比例少,产量大。该研究可为改善竹林水分条件、人工喷灌装置的投资与提高经营效益提供参考。

Abstract: Five permenant standard plots of phyllostachys pubeslens are established in the Ronggong village of Shangping township and the changing of the winter-bamboo-shoot’s quantity, individual and morphological growth in the different years and rainfall from the years of 2001 to 2005 are observed. The results indicated that the individual of the winter-bamboo-shoot is smaller and the morphology is more “rat-mouth” shaped,with the rainfall of 70mm.The study will provide a theory reference for production and practice in improving the moistural conditions of phyllostachys pubeslens stands and increasing the benefits.

Key words: phyllostachys pubeslens, winter-bamboo-shoot, rainfall, Yong’an City
