摘要
本文对生产菌肥的磷细菌和钾细菌进行了混合培养，设计了三因素随机区组试验，探讨混合菌肥的最佳生产工艺，并对实验结果进行了方差分析。结果表明磷细菌和钾细菌可以混合培养，各处理结果经ＬＳＲ测验，主效Ａ因素（混合比例）中Ａ４水平、Ｂ因素（培养基配方）中Ｂ２水平和ｃ因素（培养时间）中Ｃ５水平显著高于同组中的其它水平。Ａ４Ｂ２Ｇ５显著高于其它处理组合。；ＳＳＲ０．０１＝３．９８；ＬＳＲ０．０１，２６７＝１７．８７），Ａ因素显著水平顺序为Ａ４＞Ａ２＞Ａ５＞Ａ１＞Ａ３。但Ａ因素在方差分析中显著程度远远小于Ｃ，因此施用菌肥时当土壤缺磷大于缺钾，选Ａ４；当缺磷小于缺钾时选Ａ２。Ｂ因素即本文所用的三种培养基对细菌生长总数影响显著，Ｂ２培养基中菌数极显著地高于Ｂ３和Ｂ１培养基（Ｐ＝３；Ｘ—１１７２．７５＝４２．６１；ＳＳＲ０．０１＝３．８０；ＬＳＲ０．０１；２６７＝２２．０３３，其显著水平顺序为Ｂ２＞Ｂ３＞Ｂ１，且豆粕粉为农副产品，价廉易得，所以选择Ｂ２。表２三因素试验的方差分析Ｔａｂｌｅ２Ｔｈｒｅｅｆａｃｔｏｒａｎａｌｙｓｉｓｏｆｖａｒｉａｎｃｅ方差分析中培养时间是极其显著的因素，其中Ｃ５极显著高于其它处理（Ｐ＝６；Ｘ—４２０２?
In this paper, we studied the mixed culture of potassium bacteria and phosphorus bacteria which are used to produce bacterial fertilizer. We also designeed the three-factor randomized block experiment and discussed the optimal production technology for the mixed The results show that mixed culture is possible for the potassium bacteria and phosphorus bacteria. By means of the LSR test, we found that the level of A4IS HIGHEST ANONG A factors (propriton of mixture),the level of B2 is highest among B factors (ligredient of culture medium)and the level of C5 of culture medium)and the level of C5 is highest among C factors (culture time). A4B2C5 is most remarkable, when the three factors were taken together.
