| 摘 要： | 以平邑甜茶(MalushupehensisRehd.)当年生实生苗为试材,探讨了有机物料和氮肥对苹果生物学效应的影响,并对相关指标进行了灰色关联和通径分析。结果表明,6%有机物料+100,200mg/kg氮肥和3%有机物料+200mg/kg氮肥处理中植株生长及生理的综合指标较好,说明有机物料和氮素化肥结合施用对植株生长发育有重要作用,在生产上可以使用茎粗和生长量作为平邑甜茶实生苗品质的评判指标。 |

| Abstract: | Biological effects of the application of nitrogen and organic materials were analyzed with Malus hupehensis Rehd.seedlings as materials.Related indexes were evaluated through gray coefficient analysis and path analysis.The results showed that the treatment with 6% organic fertilizer+100,200 mg/kg N fertilizer and 3% organic fertilizer+200 mg/kg N fertilizer were better,and proved the importance of combination of organic materials with N.The diameter of stalk and growth can be used as quality evaluation index of Malus hapehensis Rehd.seedlings. |
| Keywords: | Malus hupehensis Rehd nitrogen organic materials biological effect gray coefficient analysis |
