The virus-free tube plantlets of potato （Favorita） were used as test material. A total of 3 treatments were designed, including traditional hydroponics （CK）, installing heaters （T1） and in- stalling heaters and thermal insulation device （T2）. The results showed in the Chengdu Plain in low-temperature winter, the installing of heaters and covering of thermal insulation device could maintain the hydroponic water temperature at 15-22 ~C. The potato seedlings grown in heaters and thermal insulation device-installed seedbed rooted 6.4 d earlier and emerged 13 d earlier compared to that in tradi- tional seedbed. The growth of potato seedlings grown in heaters and thermal insu- lation device-installed seedbed was more robust. Their root length, stem diameter, plant height, leaf number and fresh weight were all higher than that of traditional potato seedlings. The tuber number per plant in T1 group reached 1.7 and in T2 group reached 3.57 42 d after the cutting of hydroponic seedlings, while then the plantlets in CK group just turned into the aeroponics stage. Therefore, heating hy- droponics is conducive to advancing the cutting of virus-free seedlings and breeding robust water-cultured seedlings. Moreover, the fruiting of aeroponics seedlings is al- so advanced. The heating hydroponics plays an important role in actual production.展开更多
