【摘要】 生物试验研究表明，50μg／g的维生素B1、B2和B6混合液及20μg／g鸟囊素、阿魏酸、香草酸、水杨酸和苯甲酸单独浸种或混合浸种可促进小麦早分蘖、多分蘖，提高小麦成穗率和产量；扬花期叶面喷施，可提高旗叶的过氧化物酶活性，降低丙二醛的积累，延缓叶片衰老，提高光合效率。更多还原

【Abstract】 Through soil culture experiment,it is demonstrated that soaking wheat seeds with mixture (50μg/g) of vitamin B1,B2 and B6,allantion,ferulic acid,vanillic acid,sylisylic acid,and benzoic acid only or mixture (20μg/g) could promote wheat tiller, increase number of spike and yield,spraying with the active material could enhance DOPactivity and decrease content of MDA in flag leaf,delay senility,enhance net photosynthesis rate.更多还原
