氮浓度和pH值对云杉幼苗生长的影响

The Influences on the Growth of Picea Aspoerata Seedlings of Nitrogen Concentration and pH value

通过分析3种氮浓度及3个不同pH值基质下云杉幼苗根茎生长量的差异,通过实验表明:不同的氮浓度及不同的pH值及二者间的交互作用对云杉幼苗的萌发和幼苗的生长存在一定的影响。其中pH值对云杉种子及幼苗生长的影响作用最大。

After analysing the influence on the growth of root and stem of three different nitrogen concentration and PH matrixes , we concluded that the notrogen concentration and pH value and their interaction have influences on the germination of seeds and the growth of Picea aspoerata seedling. Among them, pH value has more influence on the germination of seeds and growth of seedlings of Picea aspoerata than the other two factors.
