黄花槐、香椿抚育管理试验初报

Experiment on Tending of Sophora xanthoantha and Toona sinersis

结合退耕还林工作,在重庆市涪陵区南陀镇对几个树种进行了护岸林造林试验,其中造林效果较好的2个树种———黄花槐[Sophora xanthoantha]和香椿[Toona sinensis(A.Juss.)Roem)采取不同的抚育管理措施,1 a后测定地径和苗高生长情况。结果表明:在三峡库区砂质土中造林,初期应采取适当的抚育措施是必要的,施肥与浇水措施应结合使用;对于苗木的地径生长,农家肥的效果好于化肥;而对苗高的生长,化肥的效果又好于农家肥;保水剂PK3005KL与农家肥搭配使用时,表现出了减效作用。

The results have shown that it is necessary to take proper tending measures in the seedling stage, if plantation is made in sand soil of Three-gorges Reservoir region. After fertilizer application, water should be supplied to seedlings. For the growth of seedlings＇ diameter, manure is better than chemical fertilizer. But for the growth of seedlings＇ height, chemical fertilizer is better. If the waterprotectant PK3005KL is used with manure together, the effect will decrease.
