摘要
温室土壤的盐碱化问题已经比较严重 ,也日益引起人们的关注。如何改良温室土壤已成为迫切的问题。该文在塑料大棚连作土壤中施用稻草及稻草配合 EM菌、乐土菌 ,进行了它们对温室土壤的改良效果试验。试验结果表明 :3种处理下 ,土壤全盐含量 (EC值 )均下降 ,微生物区系得到明显改善 ,黄瓜枯萎病减轻 ,促进了黄瓜生长发育 ,达到了缓解大棚土壤连作障碍的目的。特别是稻草 + EM菌处理黄瓜产量达到了极显著水平。
The experiment of straw, EM(effective micro organism) and beneficial Actin omycetes added to straw in greenhouse was conducted. The results suggested that EC value was decreased, micro organism community was improved obviously; the rate of withering was reduced; the growth of cucumber was promoted, the obstruction of plastic house soil was released under three treatments. Especially, at the treatment of EM added to straw, cucumber yields increased significantly.
