不同种源梭梭栽培试验与生长特性研究

The studies on Cultivation Experiment and Growth Character for Different species of Haloxylon ammodendron

从不同种源梭梭种子特性、育苗以及生长表现等方面出发,对不同种源梭梭种子千粒质量、发芽率、发芽势及出苗率、保苗率等指标进行了测定,同时对1～2年生梭梭苗木的生长量与生物量进行了观测,研究了不同种源梭梭在种子和苗木生长方面的差异及不同种源梭梭的年生长规律。最后综合各项指标选择出了2个优良的梭梭种源,它们分别为阿拉善右旗种源、民勤种源。

Based on the seed character,breeding,growth performance and so on,thousand seeds weight,germinative rate,germinative energy,rate of seedling and survival rate were determined for different seed sources of Haloxylon ammodendron,and incre-ment and biomass of one to two years old Haloxylon ammodendron were also determined,the difference of seeds and seedling growth and growth laws of different seed source of Haloxylon ammodendron were studied in this paper.Finally according to various compre-hensive indexes,Alashan Haloxylon ammodendron and Minqin Haloxylon ammodendron were considered as the best seed sources.
