摘要: 对凉山州8个县(局)苗圃的14个树种苗木分别进行小样方随机抽样,调查苗木生长及根系现状,在各样方苗木性状精度检验的基础上,采用x±s划分苗木等级,确定各树种的分级标准。其中主要树种1年生华山松Ⅰ级苗苗高9cm,地径0.23cm,Ⅱ级苗苗高范围在9~7cm,地径范围在0.23~0.20cm。3年生云杉Ⅰ级苗苗高37cm,地径0.86cm,Ⅱ级苗苗高范围37~32cm,地径范围0.86~0.63cm。

Abstract: With the random sampling method, the seedling of 14 tree species in 8 counties in Liangshan district of Sichuan province were investigated, and the grow th fact of seedling and root properties of seedlings were studied. Based on seedling properties and precision test of the different samples, the degree of seedling was classified according to the method of x±s, and the final standard of seedlings was proposed. For enample, the ground diameter and height of the first-grade seedlings for one-year-old Pinus armandi are 0.38 cm and 9 cm respectively, and those of the second-grade seedlings are 0.23~0.20 cm and 9~7 cm respectively. The ground diameter and height of the first-grade seedlings of three-year-old Picea asperata are 0.86 cm and 36 cm, and those of the second-grade seedling are 0.86~0.63 cm and 37~32 cm respectively.

Key words: seedling, standard degree of seedling, Liangshan district
