流液蔬菜栽培又称第三代蔬菜液培。它克服了原来液体培养中水培液不能自控流动、自调浓度和酸碱度等缺点而逐渐成为一种能自够大规模生产的新技术,并为蔬菜基地的工厂化创造了条件。一、流液栽培装置的结构为了能使培养液流动就要制造具有一定倾斜度的培养槽,作物的根系自由地展开在槽内,培养液自上而下流过蔬菜、瓜果类作物的根部,然后自根际流出,通过回流又进入贮水槽内。一般不会发生长时间滞留的现象。槽的宽度因作物的种类而异,通常种植番茄和黄瓜要求糟宽一点,大约需要30cm
Flowing vegetable cultivation, also known as the third generation of liquid culture. It overcomes the original liquid culture can not be self-controlled flow of hydroponics, self-adjusting the concentration and pH and other shortcomings and gradually become a new technology that can be large-scale production, and to create the conditions for the plant base of the vegetable. First, the structure of the liquid culture device in order to make the flow of the culture fluid will have to produce a certain inclination of the cultivation tank, the root system of crops in the free expansion of the tank, the culture liquid from top to bottom through the roots of vegetables, fruits and crops , Then outflow from the rhizosphere and back into the sump again. Generally does not occur long stay phenomenon. The width of the trough varies depending on the type of crop. It is usually required to plant tomatoes and cucumbers a little wider, requiring about 30 cm
