目的:研究啤酒污泥堆肥在苹果上的最佳施用方式及其增产机理。方法:采用盆栽试验方法,探讨啤酒污泥堆肥与土壤混合(H)、堆肥覆盖土壤表面(F)、混合+覆盖(HF)3种施用方式对苹果苗生长、叶片生理特性以及根系形态的影响。结果:啤酒污泥堆肥不同施用方式均能显著促进苹果苗的生长,H与HF处理在提高苹果苗干径、苗枝径、单叶片叶面积和单株叶面积方面效果更显著;不同施用方式下叶片叶绿
Objective: To study the best application mode of beer sludge compost on apple and its mechanism of increase yield. Methods: Pot experiments were conducted to study the effects of three types of application modes of beer sludge composting and soil mixing (H), compost covering soil surface (F), mixed + covering (HF) on the growth of apple seedlings, physiological characteristics of leaves and root morphology . Results: Different application modes of beer sludge compost could significantly promote the growth of apple seedlings. H and HF treatments were more effective in improving stem diameter, shoot diameter, single leaf area and single leaf area of apple seedlings. Different application methods Leaves under the leaves green
