摘  要：
以番茄品种中杂9号(晚熟品种)和中杂109(早熟品种)为试材,研究了珍珠岩+蛭石和草炭+蛭石(体积比均为2∶1)2种基质及其结合浇灌营养液对番茄穴盘幼苗生长发育、根际EC值和pH值的影响。结果表明,与基质草炭+蛭石相比,珍珠岩+蛭石营养条件较差,不利于番茄穴盘幼苗的生长。而珍珠岩+蛭石+营养液(ZZS)条件下培育的中杂109番茄穴盘幼苗壮苗指数(0.044 4)、G值(0.026 6)、花蕾长度(0.94cm)、叶片叶绿素含量(1.303mg/g),分别高出草炭+蛭石+营养液(CZS)培育的穴盘幼苗33.7%、35.0%、9.3%、2.0%,根际EC值(0.45mS/cm)和pH值(7.10)亦适合番茄幼苗生长。ZZS比CZS更有利于增加中杂9号和中杂109番茄幼苗的株高和茎粗。因此,以珍珠岩+蛭石(2∶1)基质配比结合浇灌营养液更有利于培育番茄穴盘壮苗。

摘  要：
Two tomato varieties,Zhongza 9 and Zhongza 109 with late-maturing and early-maturing,respectively,were used to investigate the influence of two substrates(perlite+vermiculite,2∶1;turf+vermiculite,2∶1)and irrigating nutrient solution on sound seedling index,G value,bud length,chlorophyll content and EC,pH under tomato plug technology.The results showed that perlite+vermiculite(ZZB) had a poor nutritional condition and was not helpful to growth and development of the tomato plug seedlings compared to turf+vermiculite(CZB).the sound seedling index(0.044 4),G value(0.026 6),bud length(0.94 cm),chlorophyll content(1.303 mg/g) of Zhongza 109 tomato plug seedlings under the perlite+vermiculite and irrigating nutrient solution(ZZS) were respectively 33.7%,35.0%,9.3%,2.0% higher than those of Zhongza 109 tomato plug seedlings under the turf+vermiculite and irrigating nutrient solution(CZS).The plant height and stem diameter of tomato plug seedlings under perlite+vermiculite and irrigating nutrient solution were higher than those of tomato plug seedlings under turf+vermiculite and irrigating.EC(0.45 mS/cm) and pH(7.10) of seedlings rhizosphere under ZZS were more suitable for the tomato plug seedlings growth and development compared with those under CZS.So perlite+vermiculite and irrigating nutrient solution were better for culturing the high-quality plug seedlings.
