【摘要】 苹果梨园施肥试验结果表明,施肥是改进苹果梨果实品质的主要措施,有机肥与化肥配合施用效果大于二者分别单施,以有机肥与N、P、K化肥配施效果最明显,比其它施肥方式总糖、还原糖、蔗糖、蛋白质、脂肪、维生素C、总酸分别提高5.5%～32.1%、5.4%～32.2%、6.9%～30.6%、5.2%～44.2%、16.3%～51.0%、6.5%～19.9%、1.4%～12.0%。有机肥的作用是提供了N、P、K营养元素,有机肥与N、P、K之间存在明显交互效应。更多还原

【Abstract】 The results of spreading fertilizer to apple-pear orchard showed that fertilizer application was the key measure to improve apple-pear quality,the combined fertilization was better than the single fertilization.The combined fertilization of organic fertilizers and N,P and K chemical fertilizers showed the best performance,and it could improve the total sugar contents 5.5%-32.1%,protein 5.2%-44.2%,fat 16.3%-51.0%,vitamin C 6.5%-19.9%,and total acid 1.4%-12.0%.The reason why organic fertilizer could improve apple-pear quality was that it took along with some nutrition elements including N,P and K.There were apparent positive effects among organic fertilizer,N,P and K.更多还原
