摘要
[目的]探讨藏柏轻基质容器苗生长与水肥处理的关系。[方法]对藏柏一年生轻基质容器苗进行不同的水肥处理,在生长季结束后调查地径和苗高。[结果]藏柏容器苗地径和苗高生长量分别随施肥量和浇水次数增多而增大;A1B1组合(1 d 1次,施肥0.1 g),地径平均生长量最大;A1B2组合(1 d 1次,施肥0.2 g),苗高平均生长量最大。[结论]水分为藏柏轻基质容器苗生长的限制因子。
[Objective] The aim was to discuss the relationship between the seedlings growth of Cupressus torulosa in containers with light medium and the irrigation and fertilizer treatments.[Method]One-year-old seedlings of Cupressus torulosa in containers with light medium were treated by different irrigation and fertilizer treatments,the height and basal diameter of seedlings were measured after the growing season.[Result] The value of seedlings height and basal diameter rose with the increase of the weight of fertilizer and watering frequency respectively;value of seedling height reached the maximum when watering once each day and fertilized 0.1 g,namely A1B2 combination,and so did the value of basal diameter as watering once ten days and fertilized 0.2 g,namely A1B2 combination.[Conclusion] Water is the limiting factor for seedlings growth of Cupressus torulosa in containers with light medium.
