| 摘 要： | 采用随机完全区组设计，对不同施肥条件下三色堇有机基质穴盘苗的根冠比和壮苗指数进行了较系统的研究。施用氮肥后，与对照相比，三色堇穴盘苗根冠比和壮苗指数显著变小。4 g/L和8 g/L的氮肥施用量对三色堇穴盘苗根冠比的影响没有显著的差异。4 g/L和8 g/L的氮肥施用量对地下部都产生了胁迫作用，两水平施肥量对根系的抑制程度大致相等。磷钾肥对三色堇幼苗根冠比的影响没有规律性且不显著，但磷钾肥使三色堇穴盘苗的壮苗指数有一定程度的降低。与对照相比，微肥施用后各苗龄在施肥后显著增加了三色堇穴盘苗的根冠比值，但对三色堇穴盘苗的壮苗指数却无明显影响。

| Abstract: | Root shoot ratio and healthy index of pumpkin plug seedling in different fertilizer application standard was systemic studied by randomized complete-block design. Root shoot ratio and healthy index of Pansy plug seedling was significantly smaller compared with the control by the application of nitrogen fertilizer.5 g/L and 10 g/L of nitrogen fertilizer have no significant difference impact on the root shoot ratio of Pansy plug seedling.5 g/L and 10 g/L of nitrogen fertilizer produced a coercive effect on th... |
