樟子松是我国北方地区主要速生用材、防护和绿化的优良树种之一,树干通直,材质良好,用途广泛。但樟子松裸根苗根系纤细,易于风干,根系断伤后不易形成新根,影响造林成活。容器苗造林可弥补上述不足,大大提高造林成活率。一、容器苗培育 1、选苗。选一年生苗木作为待装苗,起苗前浇水,随装随起。苗木要求:苗高大于8cm,无断头、多头苗,根系完整。 2、做杯。采用可降解的塑料杯,规格:上口直
Pinus sylvestris is one of the best tree species for protection and afforestation in northern China. Its trunk is straight and has good material and wide range of uses. However, the root system of Pinus sylvestris var. Mongolica is slender and easy to be air-dried. It is not easy to form new roots after broken roots, which affects the afforestation survival. Container seedling afforestation can make up for the above shortcomings, greatly improving the survival rate of afforestation. First, container seedling cultivation 1, the election seedlings. Select the annual seedlings to be installed seedlings, seedlings before watering, with the installation. Seedling requirements: seedling height greater than 8cm, no breakage, multi-head seedlings, root system integrity. 2, do the cup. Using biodegradable plastic cups, specifications: straight mouth up
