野生绿菇林间管理增产技术研究

Study on Forest Management Technology for Increasing Yield of Wild Fruit-body of Russula Virescens

摘要:

根据绿菇的生物学及生态学特性,本研究采取一系列的林间管理措施进行对比试验.结果表明:清除林下杂灌草、疏伐/间伐、林地覆草、人工开沟、林间施肥等林间管理措施均可以显著增加绿菇的自然产量,包括自然出菇数及个体均重.各种处理中,个体数均增加60.0%以上,而个体均重的增加以施肥处理效果最佳,达到24.1%.文章最后还对野生绿菇的增产提出其它的管理建议.

Abstract:

Based on the biological and ecological characteristics of Russula virescens, several forest management measures were taken comparing with the test in order to increase the fruitbody production of this species in the field. The result showed that techniques including cleaning, thinning, mulching, trenching and fertilizing could significantly increase the yield of the wild fruitbodies in terms of the numbers and the individual average weight, which increased over 60. 0%, while the effect performed the best with fertilization solution and rached 24.1% among various treatments when increased the individual average weight. Other suggestions were proposed at the end for increasing the yield.
