摘　　要：以黄瓜品种津研4号为试材,采用基质栽培,研究了7种微生物制剂对黄瓜幼苗生长、叶绿素含量及净光合速率的影响,筛选出具有明显促长效果的生物制剂,并测试了其对黄瓜枯萎病的防病效果。研究表明,每4L基质中添加创博微生物菌剂10mL(稀释600倍液)或"爸爱我"(Bio)生物有机肥30g对黄瓜促长防病效果较好,定植后植株的抗病能力明显高于对照,相对防效分别为14.5%和27.4%。为促进有机基质栽培黄瓜植株生长、防止枯萎病的发生,可在4L有机育苗基质中添加30g"爸爱我"(Bio)生物有机肥。A matrix cultivation was conducted to study the effects of 7 different species and concentrations of microbiological preparation on biomass, chlorophyll content and net photosynthetic rate of ＇Jinyan No.4＇ cucumber （ Cucumis sativus L. ）. Bioinass with remarkable growth promoting effect was screened out and their resistance to cucumber Fusarium wilt was tested. The result indicated that treatments with Ba （ bio-organic fertilizer ） and Y （ Chuang Bo microbial agents ） performed better, and the best processing concentration for Chuang Bo is adding 10 mL diluted 600 times, and for Ba is adding 30 g per nursery substrate of one plug （ 4 L ）. The plant resistance with Chuang Bo and Ba is higher than that of the control. The relative anti-effect is 14.5% and 27.4%, respectively. Under the condition of protected cultivation, for promoting cucumber growth and resistance to Fusarium wilt, we would suggest to use bio-organic fertilizer and add 30 g Bio per nursery substrate of one plug （ 4 L ）.
