采用容器苗造林是目前各项工程造林正在推广的一项造林技术。容器苗培育技术倍受育苗户的关注,现将培育容器苗的九项主要技术措施归纳总结如下: 一、容器的尺寸。选用大小合适的容器,可为种苗根系提供充足的空间,并为养分保留一定的空间,以便生产出优质苗木。一般生产上选用的容器体积应为250~2500立方厘米(P0.25~2.5升),使用时可根据树种生长快慢及培养苗木的大小而定。选用时应注意,如果选用的容器较小,则达不到最佳的根芽比率,且大大地增加管护难度。容器的尺寸也不能太大,否则会导致根系过大,影响栽植效果,有可能导致栽植后死亡,并增加了不必要的生产和运输成本。因此选用好容器可以降低育苗成本,提高造林成活率。二、容器填充物。使用的土壤应包括粗粒和土壤微
Afforestation using container seedlings is an afforestation technique that is being popularized in various afforestation projects. Container seedling cultivation techniques are much concerned with nursery households, and now nine main technical measures to cultivate container seedlings are summarized as follows: First, the size of the container. Choosing the right size container provides plenty of room for seedling roots and reserves some space for nutrients to produce good seedlings. The volume of containers used in general production should be 250 to 2500 cm3 (P0.25 to 2.5 liters), depending on the growth rate of the tree species and the size of the nursery stock when used. Selection should be noted that if the use of smaller containers, you can not reach the best ratio of root buds, and greatly increase the difficulty of management and protection. The size of the container can not be too large, otherwise it will lead to the root system is too large, affecting the planting effect, may lead to death after planting, and increased unnecessary production and transportation costs. So choose a good container can reduce the cost of nursery, improve survival rate of afforestation. Second, the container filling. Soil used should include coarse grains and soil micro
