摘　　要：以"紫京城茄"为试材,研究不同水平(每667m2 0.5、1、2、4kg)的微生物解磷菌肥对大棚茄子生长的影响.结果表明:增施微生物解磷菌肥可以提高茄子对有效磷的利用,随着微生物解磷菌肥施用量的增加,茄子的株高、茎粗、叶绿素质量分数、根系活力、产量、土壤有效磷质量分数均显著增加,当施用量达到每667m2 1kg时,各项指标达到最高值,随后趋于稳定.This experiment used 'Zi Jing Cheng Qie' as the material to research the different concentration of phosphorus-dissolving microbe fertilizer(0.5,1,2,4 kg/(667 m2))on eggplant in the vinyl tunnel.The results showed that,increasing phosphorus-dissolving microbes fertilizer application amount could advance utilization of available phosphorus to the eggplant plants.With the increase of phosphorus-dissolving microbes fertilizer application amount,the plant height,thickness,quality fraction of chlororphyll,root vigor,and yield of eggplant as well as quality fraction of available phosphorus in soil were noticeable increased,and came to a head when phosphorus-dissolving microbes fertilizer application amount was 1 kg/(667 m2),then went to the trend of stabilization.
