不同氮磷钾配比对中华猕猴桃果实产量及品质的影响

连续3 a(2008～2010年)研究了不同氮、磷、钾配比对中华猕猴桃果实产量及品质的影响,以期为制定科学的栽培技术和管理措施提供参考,并为猕猴桃合理施肥提供理论依据.结果表明:9个处理的效果都明显优于对照,其中N∶P2O5∶K2O比例以10∶ 9.4∶10的效果最好,其次是N∶P2Q∶K2O比例为10∶7.2∶10,说明适当增加钾肥施用量有利于猕猴桃的营养生长和提高果实产量和品质,而在氮磷钾肥比例中以较高的磷比例有利于提高果实的产量和品质,以较低的磷比例有利于植株的营养生长;不同施肥时期对猕猴桃植株营养生长和产量和品质等方面的影响效果不同,在4个处理中,以5月中旬施肥的效果最好,有利于树体枝蔓的伸长生长、加粗生长和提高果实产量和品质;建议在考虑猕猴桃壮果肥时,以选择N∶P205∶K2O比例为10∶9.4∶10的复合肥效果好;施肥时期选择为5月中旬,同时结合树势强弱情况加强根外追肥效果会更好.

Influence of Different NPK Ratio on Fruit Yields and Quality of the China Kiwi

In order to provide theoretical basis for rational fertilization kiwi fruit,and for formulating scientific cultivation technique and management measures to provide the reference.Three consecutive years(2008~2010)for different fertilizer that influenced on Chinese kiwi fruit yields and quality were studied.The results showed that the kiwi of plant nutrition that influenced to grow and produce quality had significiant,nine processing effects were obviously superior to that of the control processing effect,whi...
