为减少花卉无土栽培对泥炭资源的依赖和降低生产成本,研究了以锯末、玉米秆和小麦秆为主要成分的混配基质在一品红无土栽培中的应用效果。结果表明,2份玉米秆粉∶1份锯末∶1份珍珠岩和1份小麦秆粉∶2份锯末∶1份珍珠岩两种混配基质的各项理化指标均在无土栽培基质的理想范围内,用其栽培的一品红根系生长健壮,生长发育综合表现优于对照,可替代泥炭作为一品红的无土栽培基质。
In order to reduce the dependence of peat resources on flower soilless culture and reduce the production cost, the application effect of mixed substrate with sawdust, corn stalks and wheat straw as main components in Euphorbiae soilless culture was studied. The results showed that 2 corn stalks: 1 sawdust: 1 perlite and 1 wheat stalk powder: 2 sawdust: 1 perlite two kinds of mixed matrix physical and chemical indicators are ideal in soilless culture substrate Within the range, the root system of its cultivated poinsettia grew robustly, the overall performance of growth and development was better than that of the control, which could replace peat as the soilless culture substrate of poinsettia.
