| 摘 要： | 在福建省上杭县进行的火炬松施肥试验表明,造林时施肥当年就有明显肥效,单施磷肥高生长增加22%—38%,地径增加28%—41%;单株理想的施肥量为71g过磷酸钙,氮磷配合的肥料效果最佳,高生长增加81%,地径增加80%;火炬松造林当年不必施钾肥。

| Abstract: | The trial of loblolly pine (Pinus taeda L.) fertilization was con-ducted in Shanghang County, Fujian Province. The results showed that therewere significant fertilizer effects in the first year when the trees were planted andfertilized. Single phosphorus improved the loblolly pine height and ground diam-eter growth with 22--38% and 28--41% increment over the control respectivelyand the rational fertilization amount for each tree was 71g of calcium superphos-phate. The fertilization effects of the combination of phosphorus with nitrogenwere optimum with 81% increment of height growth and 80% increment ofground diameter growth over the control. It was not necessary to apply potassi-um for loblolly pine in the first year at planting. |
