| [目的]为外源5-氨基乙酰丙酸(ALA)在日光温室蔬菜上的应用提供科学依据.[方法]研究了不同浓度ALA处理对日光温室番茄生产的影响.[结果]ALA以及ALA+N叶面施用均明显提高了番茄植株株高、叶绿素相对含量和果实产量,并改善了番茄果实品质;与对照相比,外源ALA各处理植株株高、叶绿素相对含量和单株生物产量均有明显提高,其中D处理(ALA1号肥料第1次2 kg/hm2,第2～4次1 kg/hm2)效果最佳,植株株高、叶绿素相对含量及单株生物产量分别提高27.18%,17.75%和13.93%;外源ALA对番茄果实产量和品质也有明显的提高和改善作用,其中处理B(ALA1号肥料第1次0.5 kg/hm2,第2～4次0.3 kg/hm2)对果实产量效果最明显,处理E(ALA3号肥料第1次2.5 kg/hm2,第2～4次1.5 kg/hm2)对果实品质效果最佳.[结论]处理E(ALA3号肥料第1次2.5 kg/hm2,第2～4次1.5 kg/hm2)既有利于番茄生长发育,又能增加产量并改善品质,为最佳的ALA施用量及方法. |

| Abstract: |
| 【Objective】 Scientific foundation was provided for the application of exogenous ALA (5-aminolevulinic acid) in the greenhouse vegetables.【Method】 Effects of ALA application on the growth,yield and quality of the tomato in the greenhouse were studied.【Result】 The results showed that ALA and ALA+Nenhanced the plant height,chlorophyll,yield of the tomato and improved the quality of the fruit.ALA and ALA+N of all the treatments were significantly better than the control in plant height,chlorophyll,biologic yield of the tomato.The D treatment was the best of all the treatments.The plant height,chlorophyll,biologic yield of the tomato were increased by 27.18%,17.75% and 13.93%.ALA and ALA+N improved the mean yield and quality of the tomato.There was the most significant increase in the mean yield and quality of the tomato compared with the control.The B treatment was the best one for the mean yield and the E treatment was the best one for the quality of the tomato.【Conclusion】 Comprehensive analysis of the effects of ALA application on the growth,the yield,and the quality indicated that the E treatment (ALA+N) should be 2.5 kg/hm2for the first time,1.5 kg/hm2 for the second to the forth time. |
