不同肥料对杉木幼苗生长的影响

Effects of Different Fertilizers on the Growth of Cunninghamia lanceolata Seedlings

本文研究探索施加饼肥、复合肥、有机肥对杉木幼苗生长的影响。结果表明,(1)在株高方面,饼肥处理的杉木幼苗株高与复合肥、有机肥差异显著,与对照组差异极显著;(2)在分枝方面,饼肥处理的杉木幼苗分枝数量最多(3)在主根长方面,饼肥处理的杉木幼苗主根长与复合肥、有机肥处理的有显著差异,与对照组有极显著差异;(4)在茎与根干重、鲜重方面,饼肥处理的杉木幼苗茎与根干重、鲜重均最大,与复合肥处理的有显著差异,与有机肥处理和对照组有极显著差异。

In this paper,a study was made on the effects of cake fertilizer,compound fertilizer and organic fertilizer on the growth of Cunninghamia lanceolata seedlings.The results showed that:1.the heights of the seedlings treated with cake fertilizer were significantly larger than those treated with compound fertilizer or organic fertilizer and extremely significantly larger than those of the control group;2.the branching number of the seedlings treated with cake fertilizer were the biggest;3.the taproots of the seedlings treated with cake fertilizer were significantly longer than those treated with compound fertilizer or organic fertilizer and extremely significantly longer than those of the control group;4.the dry weight and fresh weight of the stem and root of the seedlings treated with cake fertilizer were the biggest,significantly different from those treated with compound fertilizer and extremely significantly different from those treated with organic fertilizer.
