| 中文摘要: |
| 为了解5-氨基乙酰丙酸(ALA)在蔬菜上的应用效果,日光温室田间试验ALA叶面喷施和土壤表面喷施以及ALA+N叶面施用对油麦菜生长发育、产量和品质的影响。结果表明:ALA以及ALA+N叶面施用和土壤表面喷施均明显提高了油麦菜的光合速率、叶绿素含量和产量,并改善了油麦菜品质;与对照相比,外源ALA各处理光合速率和产量均达到极显著水平(P<0.01),其中ALA+N叶面施用效果最佳,光合速率和产量分别提高34.7%和41.6%;外源ALA对油麦菜叶绿素含量和品质也有明显地提高和改善,并且ALA+N效果最为明显,叶面喷施和土壤喷施ALA次之,但它们三者之间差异不显著。 |
| 英文摘要: |
| The field experiment was carried out at sunlight greenhouse to study the effect of 5－amino levulinic acid （ALA） and5－amino levu linic acid＋N （ALA＋N） on the growth yield and quality of leaf-used lettuce． The results showed that ALA and ALA＋N enh anced the photosynthesis chlorophyll yield of leaf-used lettuce and improved the quality of leaf-used lettuce．ALA and ALA＋N of all the treatments were significantly better than the control（P＜0．01） in the photosynthesis and yield of leaf-used lettuce ALA＋N treatment was the best in all the treatments the photosynthesis and yield of leaf －used lettuce increased by 34．7％ and 41．6％．ALA and ALA＋N improved the content of chlorophyll and quality of leaf-used lettuce there was the most significant increase the content of chlorophyll and quality of leaf-used lettuce compared to the control．The study indicated that the application of ALA and ALA＋N increased the yield and quality of leaf-used lettuce and there was no significant difference among them． |
