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 effects of substrate weight, water absorption and water retention capacity, pH, C / N ratio, buffer properties and ion exchange characteristics of substrate in different pH nutrient solutions were studied. Soilless culture substrate rice hull ash, sawdust, cotton seed hulls Physical and chemical properties and their applications; and analyzed the problems of various substrates used in soilless culture, put forward corresponding measures to overcome; at the same time, pointed out that the wastes used as soilless culture substrates A Way to Develop Soilless Culture in China.
