【摘要】 以黄心土、废菌棒和泥炭按不同比例混合作基质,以无纺布袋和塑料育苗杯为容器,并加入一定量的缓释肥,用2年生榧树Torreya grandis实生苗作砧木嫁接细榧Torreya grandis‘Xifei’穗条后再培育1 a的小苗为材料,设置基质配方、缓释肥用量、容器种类及摆放方式3因素各3水平对其进行培育试验。结果表明,香榧苗木培育时采用无纺布容器袋比塑料杯容器袋时成活率高36.0%。苗木新梢长度受3个因素的影响中,以容器种类及摆放方式的影响最大,其次是基质配比,再次是缓释肥用量,但都没有达到显著水平;而基径的生长受容器种类及摆放方式的影响也是最大,其次是缓释肥用量,再次是基质配比,3因素对苗木地径生长的影响都达到显著水平(P<0.05)。所育苗木综合质量评价以基质配比黄心土:废菌棒:泥炭为2:1:1、无纺布容器袋高位摆放、缓释肥用量30 g·株-1为最佳方案。更多还原

【Abstract】 Experiments were conducted on container seedling cultivation of Torreya grandis ‘Xifei’ in Songyang of Zhejiang province with different substrates, different containers and different quantity of slow release of fertilizer. 1-year seedlings were T. grandis ‘Xifei’ as scion grafted on 2-year T. grandis as stock. One year later, determinations demonstrated that survival rate of seedlings in non-woven bag was 36% higher than that in plastic cup. New shoot growth of seedlings was influenced by moisture content of soil>substrate>slow release fertilizer. Ground diameter increment of seedlings was significantly affected by moisture content of soil>slow release fertilizer>substrate. Comprehensive evaluation on seedling quality resulted that the best substrate was sub top soil: waste mushroom stick: peat = 2: 1: 1, with non-woven bag as container, and 30 g slow release fertilizer each seedling.更多还原
