液化栽培技术就是把作物的根系置于盛有培养液的水槽内,从而吸收各种养分,并且依赖于培养液中的氧气进行呼吸,使作物生长发育。作物进行液化栽培时,如果培养液中的含氧量不够,可通入细管子,进行循环喷雾,增大培养液内的含氧量。因此,也可以称之为喷雾液化栽培技术。利用这种栽培技术时,水槽的下半部分盛入培养液,作物的根系悬垂于水槽内。根系的 Liquefying cultivation technology is to place the root of the crop in the tank containing the culture solution to absorb various nutrients and rely on the oxygen in the culture solution to breathe and grow the crop. Crop liquefaction cultivation, if the culture fluid oxygen content is not enough, can pass thin tubes, spray circulation, increase the oxygen content of the culture medium. Therefore, it can also be called spray liquefaction cultivation techniques. When using this cultivation technique, the lower part of the sink contains culture medium and the root of the crop hangs in the sink. Root system
