施肥对三种樟科植物容器苗生长的影响

Effects of Fertilization on the Growth of Three Lauraceae Seedlings in Containers

采用正交实验设计,研究了氮(N)肥、磷(P)肥、钾(K)肥施肥处理对闽楠、浙江楠和浙江樟3种樟科植物容器苗苗高和地径的影响。结果表明:闽楠、浙江楠、浙江樟各施肥处理间苗高差异不显著(P>0.05);而各苗木地径差异显著(P<0.05):对于闽楠P肥的影响最大,其次为N肥和K肥;对于浙江楠N肥的影响最大,其次为K肥和P肥;对于浙江樟K肥的影响最大,其次为P肥和N肥。在培育过程中,容器基质的理化性质对苗木的生长具有重要的影响。

Using an orthogonal experimental design, the paper made a study of the influences of different fertilization processes on the height and stem diameter growth of Phoebe bournei, Phoebe chekiangensis and Cinnamomum chekiangense contained seedlings. The results showed that different fertilization processes make no difference to their seedling height but a remarkable difference to their stem diameter; that among the influences of the three fertilizers. nitrogenous plays a major role in Phoebe chekiangensis, next comes potassium and then phosphate;phosphate plays a major role in Phoebe bournei, next comes nitrogenous and then potassium; potassium plays a major role in Cinnamornum chekiangense, next comes nitrogenous and then potassium. In the course of cultivating contained seedlings, some physical and chemical indexes in the culture media have important effect to the growth of contained seedlings.
