摘要: [目的]研究旨在通过验证食用菌菌渣做为育苗基质用于替代不可再生的草炭资源的可行性,促进产业和环境的可持续发展。[方法]采用A(商用育苗基质)、B(草炭:优质黄土:珍珠岩=1:1:1)、C(食用菌菌渣:珍珠岩:优质黄土=1:1:1)、D(食用菌菌渣:优质黄土:珍珠岩:复合肥=1:1:1:0.005)、E(优质黄土:火土灰=1:1)等五种不同配比育苗基质分别采用穴盘、漂浮及潮汐式育苗三种方式对辣椒出苗率、幼苗株高和茎粗、幼苗的整齐度、幼苗的真叶数、幼苗的根冠鲜重比、壮苗指数及定植后缓苗期等几个方面进行考察。[结果]结果表明育苗基质A效果最为理想。除基质E外,其余基质均可满足生产需求。基质C、D与基质B差异不显著,但存在管理较繁复问题。育苗基质E在出苗率及壮苗指数与其他育苗基质存在显著性差异。不同育苗方式对比,潮汐式育苗整体优于另两种育苗方式,漂浮育苗存在定植后缓苗期较长,育苗期间存在部分黄化现象,穴盘育苗相较于漂浮和潮汐育苗具有单位面积播种株数少,株间差异较大,同时存在管理较为繁复问题。[结论]食用菌菌渣用作育苗基质具有一定可行性,但存在一些问题,需要采取相应措施降低其不利因素。

Abstract: The research aims to verify the feasibility of using edible fungus residue as a seedling substrate to replace non- renewable peat resources, and promote the sustainable development of the industry and environment. Effects of five different ratios of seedling substrates, commercial seedling substrate(A), grass charcoal: high-quality loess: perlite= 1:1:1(B), edible fungus residue: perlite: high-quality loess= 1:1:1(C), edible fungus residue: high-quality loess: perlite: compound fertilizer= 1:1:1:0.005(D), and high-quality loess: fire-ash ash= 1:1(E), and three seedling culture modes, plug seedling, floating seedling, and tidal seedlings, on seedling rate, seedling height and stem diameter, seedling uniformity, seedling true leaf number, seedling root and shoot fresh weight ratio, seedling index, and recover period after planting were investigated. Results indicated that seedling substrate A was the best one. Except for substrate E, the other substrates could meet the production demand. The differences between substrate C, D and B were not significant, but the production management was more complicated. The seedling substrate E had the greatest impact on seedling rate and seedling index. Comparing the results from different seedling culture modes, the tidal seedling cultivation was better than the other two seedling culture modes. The floating seedling had a longer recover period after planting, and there was also partial yellowing phenomenon during seedling cultivation. The plug seedling culture mode had the problems of small number of sowing plants per unit area, large difference between plants, and complicated management. Edible fungus residue has certain feasibility as a seedling substrate, but corresponding measures are needed to tackle the problems to reduce the disadvantages.
