摘要
通过对土壤氮素、磷素、钾素在人工草地放牧系统中循环特征的分析 ,探讨了南方人工放牧草地氮素、磷素、钾素及硼、锌、钼、硫等营养元素的需求状况、肥料种类及用量、具体施肥时间与方法 。
Based on the analysis of characteristics on nitrogen cycle,phosphorous cycle and potassium cycle in grazing system of artificial grassland,nutrient elements requirement,forms of fertilizer,fertilizer rates,concrete fertilizer time and method of nitrogen,phosphorous,potassium,boron,zinc,molybdenum and sulfur in soil in grazing system of artificial grassland in southern China were discussed.Meanwhile,biological measures and comprehensive measures to increase soil fertility in grazing system of artificial grassland in southern China were pointed out.
