硅是地壳中最丰富的矿质元素之一,其含量约27.6%,为一般岩石的主要成份,但大部份不能迅速地为作物吸收利用。由于成土因素的不同,各种土壤类型的含硅量差异很大。现在,有越来越多的证据说明,某些土壤是缺硅的,特别是高度风化和高度淋溶的热带、亚热
Silicon is one of the most abundant mineral elements in the earth’s crust. Its content is about 27.6%, which is the main component of the general rock. However, most of it can not be rapidly utilized for crops. Due to the different soil forming factors, the content of silicon in various soil types varies greatly. Now there is growing evidence that some soils are silicon-deficient, especially highly weathered and highly leached tropical,
