| 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...

| Abstract: | 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. |
