三种新型叶面喷施剂对油菜菠菜和雪里蕻生长发育的影响

比较了多收宝、绿迪乐、肥田灵三种新型叶面喷施剂对菠菜、油菜和雪里蕻的增产效果，对蔬菜中绿素含量及叶片解剖结构进行了分析，并对其作用机理进行了初步探讨。结果表明，使用三种喷施剂后，三种蔬菜的产量均明显增加，蔬菜叶的叶绿素含量增高，但绿迪乐可以使蔬菜叶中绿素a/b值降低，使叶肉海绵组织增厚，肥田灵对蔬菜叶叶绿素a/b值没有影响，使叶肉栅栏组织增厚；多收宝使蔬菜叶叶绿素a/b值提高，使总叶片厚度及栅栏组织增加。这说明，这三种叶面喷施剂的作用机理不同。

Effects of Three New Spraying Solutions on the Growth and Development of Rape Spinach and Potherb Mustard

The improving effects of three new spraying solutions(Ludile\,Feitianling and Duoshoubao)on the output of Rape,Spinach and Potherb mustard were studied,respectively.The chlorophy11 content and the anatomical structure of the vegetable leaves were determined and the improving mechanism of them were analyzed.The results showed the output of vegetables treated with these three spraying solutions and the chlorophy11 content were apparent increased.Using Ludile decreased the chlorophy11 a/b ratio,but Duoshoubao increased it.Furthermore,the anatomical structures of mesophy11 tissue showed using Ludile increased the thickness of the spongy tissue,however,Feitianling increased the thickness of the palisade tissue.Using Duoshoubal increased the thickness of total mesophy11 tissue and the palisade tissue.So the improving mechanisms of these three spraying solutions were different.
