为探讨氮、磷、钾肥不同配比、不同施用量对栗树及栗瘿蜂的影响,在宽甸县大西岔镇进行了栗树施肥试验,结果表明：春施氮、磷、钾肥虽能增强树势、提高产量,但使栗瘿蜂数量上升,且施肥效益不高。对密度为4 m×5 m,树龄为15~20 a 的实生栗树而言,有栗瘿蜂的栗园不易氮、磷、钾肥的配合使用。
為探討氮、燐、鉀肥不同配比、不同施用量對慄樹及慄癭蜂的影響,在寬甸縣大西岔鎮進行瞭慄樹施肥試驗,結果錶明：春施氮、燐、鉀肥雖能增彊樹勢、提高產量,但使慄癭蜂數量上升,且施肥效益不高。對密度為4 m×5 m,樹齡為15~20 a 的實生慄樹而言,有慄癭蜂的慄園不易氮、燐、鉀肥的配閤使用。

In order to investigate the effects of different ratio & fertilizer on NPK fertilizer on Castanea spp.and Dryocosmus kuriphilus ,fertilizer experiments of Castanea spp.were conducted in Daxicha Town of Kuandian County.Result shows that applying N,P and K in spring,although energy enhanced vigor,increase production, but make Dryocosmus kuriphilus increase in the number and fertilizer efficiency is not high.So the density of 4 m × 5 m,1 5-20 a age of Castanea spp.in terms of seedling chestnut;N,P,K fertilizer is not suitable to be used in Castanea spp.orchard.
