《无土栽培学》试题库 一、名词解释 1.??????? 无土栽培技术/Soilless culture / hydroponics is the planting method with nutrient solution other than natural soil, to provide nutrients, water and oxygen. 2.??????? 表观吸收成分组成浓度/Apparent absorption constitute concentration is the ratio of the amount of nutrient absorption (n, mmol) to the amount of water consumption (w, L). 3.??????? 营养液配方/Nutrient formulation The kinds and amounts of chemical compounds are specified in the solution with a given volume. 4.??????? 营养液剂量/Stock of formula The concentration of nutrient solution is made up according to the stipulated amount of the formulation. 5.??????? 工作营养液、栽培营养液/ Cultural nutrient Solution is the solution that plants grown in directly, unit of its concentration is gram per liter or microgram per liter. 6.??????? 营养液的溶解氧/Dissolved O2 7.??????? 固体基质的缓冲作用/Buffering effect of solid medium 8.??????? 活性基质/Active medium, such as 9.??????? 惰性基质/Inactive medium, such as 10.??? 复合基质/Mixed medium is the medium mixed with two or more than two media according to the proportion. 11.??? 水培技术/Water culture is the true hydroponics by definition that parts of plant roots are immerged in a liquid medium (nutrient solution), and another parts of roots are suspended over nutrient solution. 水培是指植物部分根系悬挂生长在营养液中，而另一部分根系裸露在潮湿空气中的一类无土栽培方法。 Solution culture is the method of planting that allows parts of the roots suspending over the layer of nutrient solution, and parts of roots immerging in nutrient solution. 深液流水培技术/Deep flow technique (DFT) is a water cultural technique in which plants are grown with their root systems contained in a trough through which a deep nutrient solution is continuously circulated. 深液流水培技术(Deep Flow Technique, DFT)：指营养液液层较深、植物由定植板或定植网框悬挂在营养液液面上方，而根系从定植板或定植网框伸入到营养液中生长的技术。也称深水培技术； 13.??? 浮板毛管水培技术/Floating capillary hydroponics (FCH) 浮板毛管水培技术(Floating Capillary Hydroponics，FCH)是浙江省农科院园艺所“ 东南沿海地区无土栽培研究中心”于1991年研制成功一种新型无土栽培系统。 具有成本低、投资少、管理方便、节能、实用等特点。该系统适应性广，适宜我国南北方各气候生态类型应用。 目前FCH已
