摘要
针对我省刺梨资源不清,影响刺梨产品进一步开发的现状,本文在调查研究的基础上,提出了生态立地分类抽样和简单随机抽样两种调查方法。同时,提出了以丛数、丛高或冠幅为计量单位,通过各种数学模型估测刺梨产量的计量方法。
According to the situation that Rosa roxburghii resources in Guizhou Province is not clear and this illegibility has affected further exploitation of Rosa roxburghii products This paper based on investigation and research proposes two methods for surveying Rosa roxburghii, one being ecological habitat classifying sampling and another being simple random sampling. The paper also proposes mathematical models for measuring Rosa roxburghii yield based on cluster number, cluster height, or crown width.
