| 中文摘要: |
| 在太行山山前平原日光温室覆膜滴灌条件下，采用￠20 cm标准蒸发皿的水面蒸发量为控制灌溉参量，研究了不同蒸发皿系数（Kcp=0.4，0.6，0.8和1.0）的灌水量对早春茬口普通番茄（Lycopersicon esculentum Mill.var. commune Bailey）生长的影响。试验结果表明：番茄的株高、叶面积和叶绿素都随着灌水量的提高趋于增加；灌水量越大，产量越高，但灌溉水利用效率随之下降；番茄果实的Vc含量随灌水量的增加而降低；番茄果实的可溶性糖含量与灌水量的多少没有关系。综合考虑番茄产量、品质和灌溉水利用效率，早春茬口日光温室覆膜滴灌条件下，番茄的蒸发皿系数采用0.8较为适宜。 |

| Based on the irrigation interval of 2 days, this study was conducted to evaluate the effects of different pan coefficient (Kcp=0.4，0.6，0.8和1.0）on the growth and irrigation water use efficiency of tomato under mulch drip irrigation in solar greenhouse in 2010. Irrigation amount were detemined by water surface evaporation(Ep) measured by a standard 0.2 m diameter pan. The results showed that the plant height，LAI and SPAD reading of tomatoes all increased with the increasing of irrigation amount. The higher irrigation amount lead to the increase of fruit yields, but the highest irrigation water use efficiency were a
chieved with the pan coefficient of 0.4. The content of the vitamin C decreased with the increasing of irrrigation amount. The sugar content of the fruit had nothing to do with the irrigation amount. From the viewpoint of high yield, good fruit quality and water saving, the pan coefficient of 0.8 should be suggested as a guideline to irrigate tomatoes in solar greenhouse. |
