摘要
膨润土是以蒙脱石为主要成分的粘土岩,具有很多优良特性。本项试验采用膨润土和苗圃土壤混合、膨润土与肥料(化肥)混合,配制不同的生长基质,探讨膨润土对红丁香苗木生长的影响。测定结果表明,向土壤中加入适当的膨润土,能够促进植物的生长。但是,加入膨润土的比例不宜超过20%以上。膨润土与矿质化肥混合使用,对红丁香的生长没有明显的变化规律。配制不同的生长基质对红丁香粗蛋白和叶绿素含量有一定的影响。其中,较好的处理组合是100 g膨润土填加5 g肥料和10 g肥料。
The influence of bentonite on growth of Syringa villosa Vahl is discussed by mixing bentonite with soil and fertilizer to make up the different growth mediums. The result shows that it can mixing suitable amount of bentonite with the proportion of bentonite not over 20%. promote the growth of plants by It can＇t change the growth of Syringa villosa Vahl to mix bentonite with mineral chemical fertilizer. To make up different growth mediums can influence on coarse protein and chlorophyll ofSyringa villosa Vahl, which better combination is to mix 100 g bentonite with 5 g and 10 g fertilizer.
