三种有益微生物混合发酵液对辣椒幼苗生长的影响

采用放线菌、光合细菌、酵母菌3种有益微生物的液态混合发酵液，经稀释不同浓度后作为育苗的播种底水进行辣椒穴盘育苗试验，研究了稀释不同倍数的混合发酵液对辣椒苗期形态指标、干物质和生理指标的影响。结果表明，稀释50倍的混合菌发酵液能明显促进辣椒幼苗的生长，增加幼苗地上部和地下部的鲜重和干重，提高幼苗叶片的可溶性糖含量和根系活力，当混合菌发酵液稀释150倍时，对辣椒幼苗形态指标、干重、鲜重和生理指标的影响不大。

Effect of the fermentation broth of three kinds of beneficial microorganism on the seedling growth of pepper

In this experiment of Pepper Plug-seedling, the compound fermentation broth of Actionomycetes, PSB (Photosynthetic Bacteria) and Yeast agent, which diluted to different concentrations, was used as sowing bottom water, to study the effect of the compound fermentation broth to physiological and morphological index, dry materials of seedling stage. The result showed that the compound fermentation broth diluted 50 times obviously promoted growth, increased the fresh＆dry biomass of aboveground and underground, improved the soluble carbohydrase content and the root activity of pepper seedlings. However, the effects of fermentation broth diluted 150 times to physiological and morphological index, fresh＆dry biomass of seedlings were not obviously.
