摘要
松柏柽柳是盐碱地重要的造林树种。筛选出适宜松柏柽柳生长的容器苗类型,能够提高苗木质量,缩短育苗周期。通过不同苗龄与不同容器规格的组合筛选,得出容器规格与成活率及生长量均呈负一元二次函数关系。容器规格为Φ40 cm~Φ45 cm,苗龄为1.8 a^2.2 a(1+1,1+1.5)的容器苗为松柏柽柳适宜的苗木类型。
Tamarix is an important afforestation tree in saline-alkali soil. To improve the quality of seedlings and shorten growing-seedling period,suitable seedling type of tamarix container seedlings should be selected. Results showed that the relationship between container size and survival rate and growth was negative unitary and hypo-two function through combinations screening of different seedling age and container size. Suitable seedling type of tamarix container seedlings were:container size Φ40 cm ~ Φ45 cm,seedling age 1. 8 a ~ 2. 2 a( 1 + 1,1 + 1. 5).
