黄瓜防病促长型微生物制剂的筛选与利用

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4 L 基质中添加创博微生物菌剂10 mL（稀释600 倍液）或“爸爱我”（Bio）生物有机肥30 g 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4 L 有机育苗基质中添加30 g“ 爸爱我”（Bio）生物有机肥。

Screening and Utilization of Microbiological Preparation to Promote Cucumber Growth and Resistance

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．）．Biomass 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）
