西北苗木网2011-10-11日信息: 无土栽培手艺要点--非论采取何种类型的无土栽培，几个最根基的环节必需把握，无土栽培时营养液必需消融在水中，然后供给植物根系。基质栽培时，营养液浇在基质中，尔后被作物根系接收。所以对水质、营养液和所用的基质的理化性状，必需有所领会。
Northwest seedling network information on October 11, 2011: key points of soilless cultivation technology -- regardless of what type of soilless cultivation is adopted, several most basic links must be grasped. During soilless cultivation, nutrient solution must be melted in water and then supplied to plant roots. During substrate cultivation, nutrient solution is poured into the substrate and then received by crop roots. Therefore, we must understand the physical and chemical properties of water quality, nutrient solution and substrate.
