摘 要:为探索氮磷钾等不同肥料组合对七叶莲幼林生长及经济效益的影响,选用N、P、K、NP、NK、KP、NPK、羊粪、阿维菌素9个施肥处理,以不施肥处理(CK)为对照,开展七叶莲幼林施肥试验。3 a的试验结果表明:不同施肥处理对七叶莲幼林的地径、树高、生物量的生长影响极显著。经多因素综合评价,最佳的施肥组合是NP处理(尿素75 g·株^(-1)+过磷酸钙75g·株^(-1)),3年生幼苗平均高度达到164 cm,地径2.28 cm,萌枝数量2.88枝·株^(-1),地上部分鲜重1211 g·株^(-1);综合评价排名第1,综合评价值为0.5799;年收益是38119.5元·hm^(-2)。可推荐作为七叶莲苗木培育和造林后幼树施肥上使用。To explorethe effect of different fertilizer combinations on the growth and economic effeciency in the young Schefflera venulosa plantation,we designed the nine fertilization levels for the fertilization experiment including N,P,K,NP,NK,KP,NPK,sheep dung,abamectin and no fertilization as a comparison.The experiment time is three years.The results showed that different fertilization had a significant effect on the growth of the ground diameter,tree height and biomass.The multi-factor comprehensive evaluation indicated that the best fertilization combination is NP(urea 75 g·individual^(-1)+calcium superphosphate 75 g·individual^(-1)).The average height of seedling,ground diameter,branch number,fresh above-biomass were up to 164 cm,2.28 cm,2.88 branches and 1211g,respectively.Comprehensive evaluation ranked first and comprehensive evaluation value was 0.5799.The annual income is38119.5 yuan·hm^(-2).The fertilization can be recommended to be used as seedling cultivation and fertilization of Schefflera venulosa plantation.
