梭梭容器育苗施肥试验研究

Experiment of Fertilization for Raising Seedlings of Haloxylon ammodendron in Container

梭梭容器苗培育是实现快速和抗旱造林的重要物质基础。而梭梭容器苗培育过程中 ,掌握适宜的追肥种类和追肥时期是合理追肥的关键。根据试验结果适宜的种类应为含氮量稍高 ,含磷、钾稍低的混合肥 ;浓度应控制在 2 0 0 ppm～ 60 0 ppm之间 ;追肥时间应在播后半个月和播后

Raising seedling of Haloxylon ammodendron in container is important basis for rapid and droughtresistant afforestation. During the progress of raising seedling of Haloxylon ammodendron in container, it's the key for rational additional fertilizer to grasp suitable kind and time of additional fertilizer. Based on the experiments, the suitable kind of additional fertilizer is combined fertilizer with high content of nitrogen and low phosphonium and potassium with consistency between 200 ppm and 600 ppm. The time for additional fertilizer should be at fifteen days and sixty days after sowing.
