摘　　要：文章以铁岭地区平榛为试材进行经营密度及施肥试验。密度试验发现不同经营密度间榛林的产量差异显著,结果表明：2年生榛林最适密度为20~25株.m-2;3年生榛林最适密度为15~20株.m-2。施肥试验发现榛林从1年生开始就应该进行施肥,施肥种类、数量及二者的交互作用对2~3年生榛林产量影响差异显著,结果表明：在铁岭地区,2年生榛林施用尿素＋二胺225 kg.hm-2效果最佳;3年生榛林施用尿素375 kg·hm-2效果最佳;不同地区施肥种类和数量也有差异。Taking C.hcterophylla of Tieling region as materials,density fertilization test were conducted.Density test shows that differences among different densities of C.heterophylla were significant.Result shows that： optimum density of 2-year-old C.hcterophylla is 20-25 plants·m-2;optimum density of 3-year-old C.hcterophylla is 15-20 plants·m-2.Result in fertilization experiment shows that C.hcterophylla should be fertilized since 1 year old;fertilizer type,quantity their interaction have significant effects on yield of 2-3-year-old C.hcterophylla;in Tieling region,the optimal fertilizer result for 2-year-old C.hcterophylla is： urea ＋225 kg·hm-2 diamine;the optimal fertilizer result for 3-year-old C.hcterophylla is 375 kg·hm-2 urea;ways of fertilization are different in different regions.
