| 摘 要： | 以切花菊品种神马为材料，研究了控释肥对菊花有效养分的利用率以及生长和观赏品质的影响，结果表明，控释肥处理生长季土壤有效养分浓度变化与菊花生长需肥规律基本一致，而普通复合肥处理土壤养分浓度早期过高，中后期偏低。同一施肥水平条件下，控释肥处理的植株比普通复合肥处理的植株高，叶片数多，叶绿素含量高，花朵鲜重和干重增加。控释肥处理的叶片氮、磷、钾含量比普通复合肥处理显著增加。说明控释肥可以提高有效养分利用率，并提高观赏品质。 |
| 关 键 词： | 菊花 控释肥 普通复合肥 生长 观赏品质 |

| Abstract: | The effects of controlled release fertilizer(CRF) on the available nutrient utilization rate,growth and ornamental quality of chrysanthemum were studied with Dendrandema grandiflora Shenma as material.The results showed that the changes of soil available nutrient concentration of CRF application treatments were similar with the nutrient uptake trend during chrysanthemum growth,while that of the common compound fertilizer(CCF) application treatments were too high at early stage and too low at middle and later stage.At the same fertilization level,the plant height,leaf number,chlorophyll content and fresh and dry flower weight of chrysanthemum treated with CRF were higher than those of CCF treatments.The contents of N,P and K of chrysanthemum plants treated with CRF were significantly more than those treated with CCF.In a word,CRF could increase the available nutrient utilization rate and the ornamental quality of chrysanthemum. |
