| 摘 要： | 研究了不同氮素营养水平,按照每月氮肥施用量设6个水平,分别为纯氮10,40,80,140,200,300 mg·株-1对切花月季‘Black Beauty’品质的影响.结果发现,80～ 140 mg·株-1的氮素水平有利于月季品质的提高,10或300 mg·株-1的氮素营养均造成品质下降.月季品质与氮肥施用量呈显著的二次函数关系,可以此作为数学模型用于月季定量化施肥与品质预测.

| Abstract: | Container-grown cut rose ’Black Beauty’ was irrigated 100 mL every three days with complete nutrient solutions containing nitrogen at 10,40,80,140,200,300 mg perliter and its growth and cut flower quality was investigated in this paper.Better quality was consistently observed when roses plants receiving 80~140 mg perliter nitrogen.Quadratic relationship between the cut flower quality and nitrogen fertilizer rates was also observed and this relationship as mathematical models was applied on quantitative fertilization and quality predictions for rose.The effects of nitrogen nutrient on the cut flowers quality were comprehensively evaluated by fuzzy mathematics through their formation. |
