| 摘 要： | 研究不同氮素营养水平对切花月季产量的影响,结果表明,氮素对切花月季生产有显著影响。月施氮量为140mg/株时,‘Black Beauty’获得最高产量,其单株年产量达22.20枝,年产量可达320～344枝/m2。氮素水平过高或过低,均严重影响月季生产。适宜的氮肥水平可促进月季侧芽与水枝的萌发与成花,使得养分吸收与光合作用增强,从而促进月季的生长发育,提高产量。

| Abstract: | Container-grown rose ‘Black Beauty’ was irrigated 100mL every three days with complete nutrient solutions containing nitrogen at 10,40,80,140,200 and 300 mg/liter and its quality was investigated in this paper.The results show that nitrogen has significant effect on the cut rose production.Best quality was consistently observed when roses plants receiving 140 mg /liter nitrogen.For ‘Black Beauty’ the annual flower yield was 22.20 per plant and 320～344 per square meter.Otherwise poor quality was observed.Appropriate nitrogen level promoted the cut rose with auxiliary buds sprouting rates and the number of basal shoots,made nutrient absorption and photosynthesis enhancement,promoted the cut rose growth,increase output. |
