摘要：１９９２～１９９５年试验结果表明，在江西省分宜县页岩坡积物发育的红壤上，湿地松幼林施用Ｎ、Ｐ、Ｋ肥及其配合，使树高、胸径、蓄积等总生长量分别达到３．７２～４．０３ｍ、７．２０～７．９３ｃｍ、２７．６５０～３４．１５８ｍ３／ｈｍ２，较对照显著增长５．１％～１３．８％、７．０％～１７．８％、１５．２％～４２．４％。在各种施肥处理中，以Ｐ２Ｋ１配合的效果最佳；单施Ｎ、Ｐ、Ｋ肥均有效，但不同剂量间无明显差异。Ｐ肥的肥效与施肥时间有关，Ｐ肥对高、径的连年生长效应持续到第３年，对蓄积指标则持续到第４年仍显著；单施Ｎ、Ｋ肥对生长的明显影响主要表现在施肥当年，次年略有后效。
The fertilization trial of Pinus elliottii plantation was established on the red soilo developed from slope deposit of shale in Fenyi County,Jiangxi Province. During the first four years(1992～1995)investigation show that:1. The effectiveness of N、P、K or its combined application was tangible in this young plantation. The total growth of height (H) ,diameter breast high( DBH )、volume increment of whole woods ( V ) of treatment plots amounted to 3.72～4.03 m,7.20～7.93 cm,27.650～34.158 m 3/hm 2,which were 5.1%～13.8%,7.0%～17.8%,15.2%～42.4% over check(CK)plots respectively. 2.The effect of P 2K 1 combined application was the best,but had no significant difference compared with the effect of NP 2、P 1K 1、NP 2K 1 and single N、P、K application. There was no obvious difference between various N、P、K level treatments. The effect of P partition into two times a half per time was better than once. The total growth of V was 1.092～9.942 m 3/hm 2 which was higher than the latter. The obvious response of these treatments for the current annual increment lasted to the third year for H,DBH ,and to the fourth year for V . The obvious effect of N、K for the growth was only in the fertilization year. 3.Final results show that according to the response of young slash pine plantation to fertilization,100 kg/hm 2 of P 2O 5 partition into two times fertilization or as once basal fertilization is enough in the soil type of this test.
