| 摘 要： | 利用埋在滴头正下方0.2 m深度的真空表负压计,通过控制土壤基质势下限（-10 kPa,S1;-20 kPa,S2;-30 kPa,S3;-40 kPa,S4）,研究在太行山山前平原日光温室覆膜滴灌条件下土壤基质势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：番茄的叶面积和叶绿素随土壤基质势的提高趋于增加;土壤基质势越高,产量越高;土壤基质势-30kPa时,灌溉水利用效率最高;番茄果实的Vc含量随土壤基质势的降级而降低;番茄果实的可溶性糖含量与土壤基质势的变化梯度没有关系。综合考虑番茄产量、品质和灌溉水利用效率,日光温室覆膜滴灌条件下,早春茬口番茄的土壤基质势控制在-20~-30 kPa最为适宜。

| Abstract: | By presetting threshold of soil matric potential(-10 kPa,S1;-20 kPa,S2;-30 kPa,S3;-40 kPa,S4)to control the timing of the irrigation cycle with vacuum tensiometers buried at 20cm depth under emitters,field experiments are carried out to investigate the effect of soil matric potential on the growth of tomatoes under mulch drip irrigation in solar greenhouses in 2010.The results show that the plant height and LAI of tomatoes increase with the increase in soil matric potential.The higher soil matric potential ... |
