| 摘 要： | 于2005~2006年采用“311-A”最优混合设计施肥对大叶栎幼苗进行了盆栽施肥试验研究。分析了氮、磷、钾肥施用量与大叶栎幼苗叶片营养元素氮、磷、钾含量相关性,建立了大叶栎生物量与氮、磷、钾肥施用量的回归方程模型,对模型进行最佳施肥配比分析。结果表明,大叶栎苗期叶片营养元素含量与氮、磷、钾肥都具相关性,总体上呈正相关关系;其中钾肥呈极显著相关。不同施肥配比对大叶栎幼苗生物量的影响有显著差异。施肥方案最佳配比为处理⑧,即:N0.899 8P2.206 8K1.084 8(g/盆),按此配比施肥,当年幼苗平均生物量最高达19.72 g/盆,比最低的处理高出15.47 g/盆。

| Abstract: | In the study in 2005～2006,"311-A" optimal mixed design fertilization on the leaf of Castanopsis fissa was adopted in the pot fertilization experiment.The relativity of dosage of N,P,K fertilizers and content of N,P,K nutritive element in the leaf of Castanopsis fissa seedling was analyzed.The regression equation model of biomass of Griffith oak and dosage of N,P,K fertilizer was established,with which the optimal fertilization matching was analyzed.The result showed that the nutritive element contents in leaf of Castanopsis fissa in seedling stage had positive correlation to N,P, K fertilizer as a whole,and that to K fertilizer was extremely remarkable.The effects of different fertilization matching on biomass of Griffith oak seedling were significantly different.The optimal fertilization matching was treatment No.8(N0.899 8,P2.206 8,K1.084 8 g/pot).Fertilizing according to the matching,the average optimal biomass of seedling in that year was up to 19.72 g,being 15.47 g higher than the worst treatment. |
