摘要：１９９１～１９９５年试验结果表明，在江西分宜花岗岩残积物发育的黄红壤上，杉木幼林施Ｎ、Ｐ、Ｋ及配合处理，使树高、胸径、蓄积总生长量指标分别达到５．６７～６．５９ｍ、８．３５～９．２８ｃｍ、６７．９２２～９６．４１７ｍ３／ｈｍ２，较对照增长５．６％～２０．２％、７．４％～１７．５％、２１．６％～５６．２％。在各种施肥处理中，以５０ｋｇ／ｈｍ２Ｐ２Ｏ５的效果最佳，其连年生长量效应显著持续到第５年；将同等剂量的Ｎ分两次各半施用，其连年生长效应在第５年时才有显著表现；Ｋ的连年生长效应仅表现在低剂量分两次隔年施用上；试验未看出Ｎ、Ｐ。
This paper reports the results of a five year research on current annual increment response to fertilization in young Cunninghamia lanceolata plantation on the yellow red earth developed from granite in Fenyi County of Jiangxi Province.The effectiveness of N,P,K and 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 5.67～6.59 m,8.35～9.28 cm,67.922～96.417 m 3/hm 2,which were 5.6%～20.2%,7.4%～17.5%,21.6%～56.2% over check(CK) plots respectively.And the current annual increment response was analyzed.The effect of 50 kg/hm 2 P 2O 5 (Calcium magnesium phosphate) as half the amount as basal fertilization and the other half as top dressing at the third year time or once basal was the best,it′s current annual increment response was obvious in the first year of planting and lasted to the fifth year.The effect of the same application amount of N(Urea) as half the amount for top dressing for two times was better than that of once.The response of K (Potassium chloride) application appeared when it′s applied with lower amount for two times in two years.There was no obvious interaction response of the application of N,P,K.
