鉴于目前沙棘刺测定方法多,不尽统一,对各种方法的准确性与可靠性也缺乏分析讨论,本文首先分析讨论了沙棘棘刺密度的概念,利用5龄沙棘棘刺的实测数据相关分析法分析了3种现行常用的测算法的准确程度。结果发现单位长度2年生枝系上的刺数能很准确地代表整株沙棘的棘刺密度。 In view of the current seabuckthorn determination methods are not uniform, the accuracy and reliability of various methods are also lack of analysis and discussion, the paper first analyzed and discussed the concept of seabuckthorn thorns density, the use of 5-year-old seabuckthorn measured data correlation analysis The accuracy of the three commonly used algorithms. The results showed that the number of thorns on two-year-old branches per unit length could accurately represent the thorn density of whole seabuckthorn.
