辽宁不同类型水稻土供硅能力及硅肥肥效试验结果表明 ,采用pH4醋酸缓冲液法测定的土壤有效硅含量能够反映非碱性水稻土的硅素肥力水平 ,但不能够反映碱性水稻土的硅素肥力水平 ,碱性水稻土测定结果高 ,但硅素肥力水平低。施用硅肥能够增加植株体内硅的含量 ,改善水稻的生长状况 ,提高水稻的产量 ,增产幅度最高可达 3 0 .1%。
The results of silicon fertilization and fertilization experiments on different types of paddy soils in Liaoning Province show that the available silicon content measured by pH4 acetate buffer method can reflect the fertility level of silicon in non-alkaline paddy soil, but can not reflect the content of silicon in alkaline paddy soil Fertility level, alkaline paddy soil determination results are high, but the low level of silicon fertility. The application of silicon fertilizer can increase the content of silicon in plants, improve the growth status of rice and increase the yield of rice, up to 30.1%.
