摘要
从基质的容重、吸水保水性能、pH值、C/N比及基质在不同pH园试营养液中的缓冲性能和离子交换特性等方面研究了无土栽培基质稻谷壳灰、锯木屑、棉籽壳理化性质及其应用;并分析了各种基质用于无土栽培中存在的问题,提出了相应的克服措施;同时还指出利用栽培过食用菌后残留的培养基等废物作为无土栽培基质是发展我国无土栽培的一条途径。
The physicochemical characteristics of soilless substrates, i.e. carbonized rice hull, sawdust, shiitake-grown sawdust, cotton seed coat, and straw mushroom-grown cotton seed coat (SMCSC) were studied in the following aspects: volume weight, water-absorbing quality, water-retaining capacity, pH value, C/N ratio, and ion exchange quality. The physicochemical characteristics of substrates such as sawdust and cotton seed coat were greatly improved after growing edible fungi. The problems arid the overcoming methods in the use of these substrates for soilless culture were also discussed.
