不同营养组合和施肥量对切花百合光合特性及干物质含量的影响

Effect of Nutrient Combinations and Fertilizing Amount on the Photosynthetic Characteristics and Dry Matter of Cut-flower Lily

以OT系百合品种‘Manissa’为试材,研究了进口花多多肥的不同营养组合A、B组及自配的分析纯复合肥C组配方与施用量对其切花植株叶绿素含量、光合特性、干物质积累等品质的影响,以期对切花百合进行科学精准施肥提供参考。结果表明:百合肥料的施用量≥7.5g/株时的光合能力及干物质累积量均优于不施肥的对照和施用量较少的2.5g/株的处理组,且花多多组合A组在7.5g/株时,干物质累积达到最大值。而在施肥量12.5g/株的情况下,自配的分析纯C组和花多多B组明显优于A组,且C组对百合‘Manissa’品质的改善效果最佳,B组次之。

Taking the cut-flower of OT type Lily＇ Manissa＇ as test material, under different level of fertilization, the effects of quality at different nutrient combinations A, B that were from imported fertilizer Hua Duoduo and C from AR （analytical regent） chemicals on the plant of chlorophyll content, photosynthetic characteristics and amount of dry matter in the experiment were studied-so as to fertilize the Lily more scientifically and accurately. The results showed that the photosynthetic ability and the amount of dry matter accumulation of 7. 5 g/ plant and 12. 5 g/plant treatments were obviously superior to the control group CK and 2. 5 g/ plant treatment groups. Under 7. 5 g/ plant treatments, the dry matter accumulation of group A was higher than the other two groups and got the maximum benefit with low input as well. Under 12.5 g/plant treatments .the group C and B were better than the group A in the photosynthetic ability and accumulated quantity of dry mattervand group C had the best effect on the improvement of lily cut flower followed by group B.
