摘要
通过苗圃中不同断根方式、不同基质填充、不同施肥方式三个对比试验,研究更好的乌桕容器苗全冠移栽方法,为大规格全冠苗移栽提供技术支持。断根实验为从休眠前到萌芽后做不同时间不同断根次数的对比,结果表明,不同断根方式对生长势影响最为显著,多次、休眠期断根组远好于单次、萌芽期断根组;基质实验为园土、泥炭、中粗砂、发酵木屑作不同配比的对比。结果表明,不同容器基质对生长势影响比较显著,兼顾养分与透气性的基质表现更好;施肥实验为同等总养分含量的有机肥、缓释肥、复合肥作对比,结果表明,不同施肥方式对生长势影响不显著,用复合肥在生长期薄肥勤施的组别表现略好。
This article conducts three comparative experiments on different root cutting methods,different substrate filling,and different fertilization methods in nurseries to study better methods for transplanting Sapium sebiferum container seedlings,providing technical support for the transplantation of large-sized full crown seedlings.The root cutting experiment compared different time and times of root cutting from before dormancy to after sprouting.The results showed that different root cutting methods had the most significant impact on growth potential,and the multiple and dormant root cutting groups were much better than the single and sprouting root cutting groups;The substrate experiment compared different ratios of garden soil,peat,medium coarse sand,and fermented wood chips.The results showed that different container substrates had a significant impact on growth potential,and the substrate that balanced nutrients and permeability performed better;The fertilization experiment compared organic fertilizer,slow-release fertilizer,and compound fertilizer with the same total nutrient content.The results showed that different fertilization methods had no significant impact on growth potential,while the group using compound fertilizer with thin and frequent application during the growth period performed slightly better.
