| Abstract: | A fertilization experiment was conducted in Jatropha curcas plantation in 1997.Fifteen treatments with different combinations of fertilizers and a control(without fertilization) were set up.The annual growth of tree height,diameter at breast height,fruit yield per tree,and soil nutrients were analyzed in order to study the effect of fertilization on the growth and soil fertility of J.curcas plantation.Results show that fertilization has certain effects on tree height,ground diameter,and fruit yield of J.curcas.Compared with the control,the tree height of J.curcas in the treatment 12,13,and 14 increased by 44.44%,71.11% and 43.33%,and the ground diameter increased by 55.29%,65.88% and 21.17%,respectively.The fruit yields of J.curcas in the treatment 13 and 14 were 2.67 kg and 2.85 kg higher than that in the control.The mixed fertilizer of potassium and phosphorus exhibited the most obvious effect on the soil pH,followed by the compound fertilizer and potassium fertilizer.The contents of soil organic matter,total nitrogen,total phosphorus,effective nitrogen and effective phosphorus in all the treatments increased after fertilization compared with the control.Soil microorganism quantity in the treatment 13 increased after fertilization,and the total amount of microbes reached 27.86×107 individuals per gram. |
