| 摘 要： | 为探究不同施肥处理对油茶生长及土壤肥力的影响,连续3年在广西柳州市对5年生油茶人工林进行施肥试验研究。结果表明,施肥后,处理Ⅱ的树高、地径和冠幅的增长量明显高于其它处理,即有机—无机复混肥料直接施入油茶林地最有利于营养生长,而处理CK(不施肥)各项生长指标的增长量最低。不同施肥处理对油茶林地土壤养分各指标的影响差异较大,经灰色关联度法分析得出土壤综合肥力的高低顺序,其中处理Ⅲ(即无纺布包装有机—无机复混肥)施肥后对油茶林地土壤综合肥力的提高最显著,其次为处理Ⅰ(即有机栽培肥料),不施肥处理CK的土壤综合肥力则显著降低,土壤质量退化严重。

| Abstract: | In order to explore the effects of different fertilizers on growth and soil fertility of Camellia oleifera,five-year-old Camellia oleifera plantation was studied in Liuzhou City of Guangxi for three consecutive years.The results showed that the growth of tree height,ground diameter and crown of treatment II was significantly higher than that of other treatments.The organic-inorganic compound fertilizer applied directly to Camellia oleifera forest was the most beneficial to vegetative growth,while the growth index of CK was the lowest.The effects of different fertilizers on the soil nutrient indexes of Camellia oleifera forest were quite different.The sequence of soil comprehensive fertility was obtained by the analysis ofcorrelation degree,among which treatment III(non-woven packaging organic-inorganic compound fertilizer)increased the soil comprehensive fertility of Camellia oleifera forest most significantly after fertilization,followed by treatment I(organic cultivation fertilizer),but soil comprehensive fertility of CK decreased significantly without fertilization,and soil quality deteriorated seriously. |
