水培花卉是用非固体介质（水或水中加入适量的植物营养液）在栽培观赏植物。目前家庭水培花卉多为静止水栽培，溶解氧低于1mg/l，花卉是在缺氧的器皿中勉强维持生命。随着夏季气温升高植物生理代谢旺盛，微生物大量繁殖，耗氧量剧增，溶解氧不断减少，水质恶化，对水培花卉的生长形成诸多不利因素，可能引起根系腐烂，枝叶萎焉，甚至使植株花卉夭折。因此，夏季除预防酷暑高温，提高营养液含氧量是确保水培花卉安全度夏之关键。

1、增加更换营养液的次数更换营养液是增加溶解氧的最简易的方法。经测量，新鲜营养液溶解氧含量较原液增加70%-90%，能及时改善花卉生理缺氧的状况。已长出水生根的花卉3-5天最多不超过7天换一次营养液为宜。更换营养液时注意新液与原液的温差不应过大，温差太大可能引起花卉根系生理紊乱。换液时应该耐心地用清水冲洗根系，剔除枯萎根、腐烂根，将老化根截短促生新根。营养液若突然变的混浊，或有蚊虫卵块，应该即刻更换新的营养液。
2、振动增氧器皿较小的水培花卉，只要根系清晰无损伤，营养液透彻，可以用振动法增氧，操作方法是一手固定花卉，另一只手把握器皿，轻轻摇动10余次，摇动后的营养液溶解氧含量量能够提高30%以上。营养液混浊、根系发育不良的水培花卉不宜采用振动增氧的方法，必须彻底更换营养液。
