文摘内容 During 1991-1995,the growth responses of young slash pine to N,P and K fertilizers and rational rate and ration of fertilizer in yellow-red soil at Fengshushan Forest Farm Jiangxi Province were studied.N fertilizer decreased the growth of slash pine,while P no only significanlty improved the increment of bottom diameter,height and crown diameter,but also caused earlier canopy closure of the stand.It also had a sustainable effect in the next two years.Slash pine had the most significant response to the treatment of 200 kg P2O5 ha^-1 ,in which tree height,bottom diameter and crown diameter(EW and SN) were increased by 22%,35%,20% and 18% i 1994,21%,25%,10% and 10% in 1995,respectively,compared to the control.Although there was no remarkable response to K fertilizer,good growth response to the application of 100 kg P2O5 plus 100 kg K2O ha^-1 existed and tree hieght ,bottom diameter and rown diameter(EW and SN ) were increased by 31%,14%,23% and 21%,respectively,in 1993 ,compared to the control。
