南果梨专用肥对其产量和品质的影响

The Effects of Special-compound Fertilizer for Pyrus ussuriensis Maxim.nanguo on its Yield and Quality

以6-10a生南果梨树为试材，于2006年在鞍山千山区绿色果品有限公司果园基地进行为期1a的有关南果梨专用肥的应用研究，取得了明显的效果。结果表明：不同的南果梨专用肥施用量对南果梨的产量和品质都有显著的影响；在一定施肥量范围内，随南果梨专用肥施用量的增加，产量和品质有明显提高；根据回归方程求得施用南果梨专用肥11．82kg／株时，南果梨产量达到最高，营养品质和外观品质最佳；如继续增加施用量，其产量和品质则会降低。
