【摘要】 试验研究了5种2∶18系列的钼磷酸稀土盐对黄瓜和番茄上2种病原真菌的抑制作用。结果表明:钼磷酸稀土盐对供试的黄瓜黑星病菌(Cladosporiumcucumerinum)均有一定程度的抑制作用,抑制强度因杂多酸稀土盐的不同结构以及黄瓜黑星病菌(Cladosporiumcucumerinum)的生理生化的特性不同而有较大的差异。其中铈钼磷酸和镨钼磷酸稀土盐对真菌抑制效果显著,钕钼磷酸对真菌抑制作用也较明显。对保护地番茄的叶霉病(Cladosporiumfulvum)喷洒试验表明:杂多酸稀土盐对该菌有抑制作用,且效果明显。更多还原

【Abstract】 The inhibition of 2∶18 series molybdophosphate lanthanides（Ce,Pr,Nd,La,Gd） salts to fungi on cucumber and tomato was studied.The effects of these heterozygous acid rare earth salts to Cladosporium cucumerinum were determined in the PAD vitro. The results showed that the Cladosporium cucumerium tested was inhibited by these heterozygous acid rare earth salts.The antifungal　activity varied greatly with the differences of the structure of these heterozygous acid rare earth salts and the biochemical and biology properties of Cladosporium cucumerinum. The effect of Ce₂P₂Mo₁₈ and Pr₂P₂Mo₁₈ was obvious and that of Nd₂P₂Mo₁₈ was slightly obvious.The following spraying test on tomato Cladosporium fulvum in the protection conditions showed that some heterozygous acid rare earth salts can inhibit Cladosporium fulvum and the effect is good.更多还原
