摘 要:研究羊粪对香榧(Torreya grandis cv. Merrillii)幼林根径、新梢生长的影响,以种植6年的香榧幼林为研究对象,以羊粪、高塔硝硫基复合肥为试验材料,分别观测榧树生长的变化。结果表明:施肥后榧树的生长量与不施肥对照之间达到极显著差异(P-value<0.01),不同肥料之间,施羊粪的树高、根径、冠幅、新梢长度和新梢基径分别比施高塔硝硫基复合肥增加20.11%、10.32%、29.48%,20.09%、12.12%。而且,2种肥料的施肥成本差不多,为此,羊粪这种肥料值得在香榧的培育经营中推广应用。

Abstract:The effects of sheep manure on root diameter and shoot growth of young Torreya grandis were studied. The young Torreya grandis plantation planted for 6 years was used as the research object, and sheep dung and nitrate-sulfur compound fertilizer were used as experimental materials to observe the changes of Torreya grandis growth. The results showed that there was a significant difference between the growth of Torreya grandis after fertilization and the control without fertilization (P-value<0.01). Among different fertilizers, the tree height, root diameter, crown width, new shoot length and new shoot base diameter of sheep dung application were increased compared with those of nitro-sulfur compound fertilizer application 20.11%、10.32%、29.48%,20.09%、12.12%. Moreover, the costs of the two fertilizers were similar, so sheep dung was worth popularizing and applying in the cultivation and management of Torreya grandis.

香榧(Torreya grandis cv. Merrillii)為榧树(Torreya grandis)中的一个品种,是我国(浙江)[1-2]特有的珍稀经济树种,是世界上重要的果材兼用型油料干果树种,兼有美味干果、木本油料、保健食品及园林绿化等功能[3]。为提高单位产量和质量,有关专业人士开展了各种类型肥料试验,戴文圣等[4]提出以复合肥为主,王珍等[5]研究的结果是菜饼肥效果最好,韩宁林等[6]研究,施用猪栏肥对生长结实有利,周智峰等[7]研究,施用菜饼肥和沼液(沼渣)成本适中且效果好。翁永发等研究了解磷菌、混合菌处理可促进容器苗生长[8],但施用羊粪是否会影响香榧林的正常生长方面尚未涉及。所以,本研究试图通过对香榧幼林,开展施用羊粪、高塔硝硫基复合肥和不施肥的比较试验,分析树高、根径、冠径和新梢生长等指标,旨在为广大农户选择适用香榧幼林生长的、经济实惠的农家有机肥,在香榧林丰产栽培中推广应用。
