- 摘 要：常施用化肥既影响蔬菜品质，又会对土壤造成危害,现以印度梨形孢为试材，以莴苣为研究对象，在莴苣幼苗期加入印度梨形孢（Piriformospora indica ）菌剂组，以不施加任何肥料为对照（CK），研究了生物菌剂印度梨形孢对莴苣的增产提质作用，以期为莴苣高产高质栽培以及新型菌肥的开发研制提供理论依据。结果表明：施加印度梨形孢的莴苣株高较对照组提高13.7%，叶鲜重较对照提高61.9%，茎粗较对照组提高12.5%，茎鲜重较对照提高53.2%，根鲜重较对照组提高15.1%；品质指标中施加印度梨形孢的莴苣茎和叶中蛋白质含量分别较对照提高90.0%和15.6%，茎和叶中还原性糖含量较对照分别提高30.4%和72.9%，茎和叶中维生素C含量分别较对照提高59.5%和73.6%；建议农民在莴苣种植的苗期施加印度梨形孢菌剂，可显著提高莴苣的产量和品质。

- Abstract:Chemical fertilizers often affect the vegetable quality and do harm to the soil.In order to settle this problem，the research of the effect of P.indica on lactuca ，s yield and quality were studied，this study could provide theoretical basis for high-yield cultivation of lactuca and development of new bacterial fertilizer.Taking P.indica as material,and taking Lactuca satira as reasearch object,no fertilizer treatment as control (CK)，and application of P.indica at seedling stage.The results showed that the P.indica had significant influence on yield of lactuca.Plant height was increased by 13.7%，stem thickness was increased by 12.5%，root fresh weight was increased by 15.1%，stem fresh weight was increased by 53.2%，and leaf fresh weight was increased by 61.9% compared with CK.The results also showed that P.indica not only could promote yield，but also could increased quality.The content of proton was increased by 83.33% and 12.25% in stem and leaf respectively.In addition，the content of soluble sugar was increased by 27.53% and 15.24% in stem and leaf respectively.The vitamin C content was increased by 59.5% and 73.6% compared with CK in stem and leaf respectively.All above results showed that P.indica had a very marked effect on yield and quality of lactuca.It was the best to fertilize in seedling stage.
