摘  要：
为明确印度梨形孢菌液在油菜上的最佳施用时期,研究了在油菜不同生育时期(苗期、蕾期、花期、荚期)施用印度梨形孢菌液对油菜的增产作用及其机制。结果表明:与CK(不施加印度梨形孢菌液)相比,苗期施用印度梨形孢菌液能显著提高油菜的根质量;花期、荚期施加印度梨形孢菌液可显著提高油菜的千粒质量和单株产量,其中单株产量比CK分别增加27.43%、27.95%。各时期施加印度梨形孢菌液均能提高油菜的实际产量,其中荚期加菌处理的实际产量最高,达3 004.65 kg/hm2,较CK增产37.30%,增加经济效益2 448.90元/hm2。生理指标测定结果表明,施用印度梨形孢菌液可以降低MDA含量,提高POD、SOD活性,进而提高油菜的抗逆性,促进油菜产量的提高。

摘  要：
To illuminate the best date of fertilizing Piriformospora indica into rape field,the yield increasing effect of Piriformospora indica on rape and its mechanisms were studied at different periods of rape( seedling,bud,flowering,pod stages). The results showed that Piriformospora indica could improve significantly the weight of rape roots at seedling stage of rape compared with CK( no Piriformospora indica). Piriformospora indica could significantly increase the thousand grain weight and yield of rape per plant at flowering and pod stages. The output per plant increased 27. 43% and 27. 95% respectively at the two stages compared with CK.The fertilization of Piriformospora indica could improve the actual production at each period of rape,but fertilization at the pod stage was better than at other stages,with the actual production reaching 3 004. 65 kg / ha,increased by 37. 30% compared with CK,and the economic income increasing 2 448. 90 RMB / ha. The test results of related physiological indexes showed that Piriformospora indica could decrease the content of MDA and increase the activities of POD and SOD in rape,which indicated that Piriformospora indica might increase the resistance of rape,and promote rape yield enhancement.
