沙棘是雌雄异株树种。为了提高沙棘浆果产量,抚育改造好成林,使雌雄株比例适当;为了采集穗条进行无性繁殖以及开展沙棘生物学特性研究,均需进行雌雄株鉴别。从外观上鉴别沙棘雌雄株,必须在生殖期内进行,而且要经过细致观察才能找出其细微差别。根据我们观察并参考国内外资料,现将中国沙棘(亚种)雌雄鉴别方法介绍如下: (一) 生长期外观鉴别雄株:①雌雄混生的沙棘林中,一般雄株高大、直立、生长旺盛,叶色浓绿,枝叶繁茂。②2—3年生枝上宿存有黑灰色短簇0.5—1厘米长花序梗。
Seabuckthorn is a dioecious tree species. In order to improve the yield of seabuckthorn berries, tending to transform into a good forest, so that the ratio of male and female plants appropriate; in order to collect culms for vegetative propagation and to carry out the biological characteristics of seabuckthorn, male and female plants need to be identified. Seen from the appearance of male and female plants seabuckthorn, must be carried out during the reproductive period, but also through careful observation to find out the nuances. According to our observation and reference to domestic and foreign information, now male and female Chinese sea buckthorn (subspecies) identification methods are described below: (a) the appearance of the male plant growth and identification: ① male and female mixed seabuckthorn forest, the general male tall, erect, vigorous growth Leaf color green, lush foliage. ② 2 - 3-year-old branch has dark gray short tufts 0.5-1 cm long peduncles.
