摘要：以1997年种植的麻疯树人工林为研究对象,对该林分所在的林地进行施肥试验,设置了15个施肥与对照相比,树高分别增加44.44%、71.11%和43.33%,地径分别增加55.29%、65.88%和21.17%;处理13、处理14使麻疯树产果量比对照增产2.67kg和2.85kg;从土壤pH值变化分析,钾、磷混合肥对麻疯树林地酸碱度影响最明显,其次是复合肥,最差是施K肥。施肥后,各施肥处理土壤有机质、全N、全P、有效N和有效P的质量分数均较对照增加,处理13与施肥前相比,土壤微生物数量呈现增长趋势,微生物总数达到了27.86×107个.g-1。
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 tile ground diameter increased by 55.29%, 65.88% and 21.17%, re- spectively. 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 27.86×10^7 individuals per gram.
