毛竹笋用林三笋高产高效技术研究

本文研究表明：毛竹笋用林三笋高产高效经营具有很高的经济效益，经13户示范户1.64/hm^2样地1998-1999年的统计，平均产笋57 705kg/hm^2，产竹材14 954kg/hm^2，平均产值103 177.71元/hm^2。其中冬笋2192kg，产值18 697.76元；春笋50 095kg，产值63 620.65元；鞭笋5 418kg，产值20 859.3元。最高产量可达97 219kg/hm^2，最高产值1 705 559.03元/hm^2，冬笋最高产量达9 767kg/hm^2，产值达83 312.51元/hm^2，春笋最高产量达84 462kg/hm^2，产值达107 266.41元/hm^2，鞭笋最高产量达11 528kg/hm^2，产值达44 382.8元。其竹林结构立竹株数3150株/hm^2，以1-3届竹为主，平均胸径9cm左右，竹鞭分布均匀，以1-6年生鞭为主，经营技术措施调整产笋结构，着重提高冬笋鞭笋的产量。

Research of High-productive and High-effectiveTechnology on Bamboo Shoots and Bamboo Forest

Research shows that high productive and high effective management of bamboo shoots and bamboo forest has high economic efficiency. After the survey of 1.64hm2 sample earth from 13 families from 1998 to 1999 equally produce bamboo shoots 57705kg/hm 2, bamboo 14954kg/hm 2, output value 103177.71 yuan/hm 2, among which winter bamboo shoots is 2192kg, 18697.76yuan; spring bamboo shoots 50095kg, 6320.65yuan; rhizome bamboo shoots 5418kg, 20859.3 yuan. Highest output can reach 97219kg/hm 2, highest output value 1705559.03 yuan/hm 2; winter bamboo shoots 9767kg/hm 2, 83312.51yuan/hm 2; spring bamboo shoots 84462kg/hm 2, 107266.41yuan/hm 2; rhizome bamboo shoots 11528kg/hm 2, 44382.8 yuan/hm 2. The number of bamboo is 3150 per hm 2, among which, the main parts are 1-3 years, average diameter is near 9cm, and rhizome distributes evenly, mainly 1 6 years' rhizome, manage technical measures to adjust bamboo structure in order to raise output of winter bamboo shoots and rhizome bamboo shoots.
