摘要
探究不同肥料类型对油茶树体生长、果实养分含量及其油茶产量的影响,从而选择最佳肥料应用于农林施肥,为提高经济效益奠定基础。本试验设置4个处理,即每年每株施用复合肥、油茶专用复合肥和油茶专用有机肥(0.2 kg、0.3 kg、1 kg)以及空白对照来开展施肥试验。并测定了不同的油茶树体指标、油茶果实养分及油茶果实产量指标来比较和分析不同处理间的差异。研究结果表明:对于油茶树体指标而言,在4个处理中,油茶专用复合肥对油茶树体生长的促进作用最佳;对于油茶果实养分含量而言,施用油茶专用有机肥具有显著促进果实养分含量累积的作用。对于油茶产量而言,油茶专用有机肥比其他处理更能促进果实产量。油茶树体指标、油茶果实养分指标及油茶产量指标间有及其密切的相关性。本试验结果表明:施用油茶专用有机肥在油茶生产与经营上最为有效。
To explore the different fertilizer types on Camellia oleifera body growth, fruit nutrient content and the impact of oil-tea production, so as to select the best fertilizer to guide forestry fertilization lay a foundation for improving the economic benefit.This test set up four processing, the annual application of a compound fertilizer, organic fertilizer for special compound fertilizer and differential（0.2 kg, 0.3 kg and 1 kg） and ck to fertilization experiment. And the determination of different index, fruit nutrient and differential fruit production index to compare and analyze the differences between different processing.The results show that for Camellia oleifera body index, in four processing, camellia has the best effect on the growth of the special compound fertilizer on Camellia oleifera; For camellia fruit nutrient content, the application of differential special organic fertilizer significantly promote the fruit nutrient content accumulation effect.For oil-tea production, oil-tea special organic fertilizer can promote fruit yields more than other treatment. Camellia oleifera body index, index of fruit nutrients and differential output index has and the close correlation between.The experimental results show that the application of differential special organic fertilizer is most effective in oil-tea production and management.
