硅是土壤矿物质中含量最多的元素之一，而土壤溶液中能供给植物吸收利用的硅素却很少，且不同成土母质的土壤差别很大。１９９５～１９９７年我们在棉花上进行了高效硅肥应用效果研究，探讨棉花施用高效硅肥的增产效应，为大面积推广应用提供科学依据。１试验基本情况试验... Silicon is one of the most abundant elements in soil minerals. However, the amount of silicon that can be supplied and utilized by plants in soil solution is very small, and the soil of different soil-parent materials varies greatly. From 1995 to 1997, we studied the application effect of high-efficient silicon fertilizer on cotton and explored the yield-increasing effect of high-efficiency silicon fertilizer applied to cotton, providing a scientific basis for large-scale popularization and application. 1 test the basic situation test ...
