| 摘 要： | 为研究名贵兰花的水培技术，促进水培兰花的生产与消费，以兰科卡特兰为试材，从卡特兰水生根系诱导，营养液培养，筛选出水培卡特兰诱导根系的最适宜的NAA浓度和营养液配方，在培养的过程中，防治根腐烂和水藻的生成。结果表明，低浓度NAA（5mg/L）对诱导水生根系具有促进作用；KC营养液是水培卡特兰较好的营养液；加强根部通气有利于防止卡特兰根系的腐烂，在培养过程中添加2～3滴含氯霉素的滴眼液有助于防止藻类的生长。

| Abstract: | In this paper Cattleya hybrida was used as the main test material to study the technology of hydroponic culture. With different concentrations of 1-naphthlcetic acid (NAA) treatment to induce aquatic root system, the aim was to choose the best concentration of NAA. After the water-cultivated-root growed, different nutrient solutions (clear water, 1/4MS, Hoagland solution and the KC nutrition) were used to culture the plantlet of Cattleya hybrida in order to find suitable nutrient solutions to promote Cattleya hybrida growth and development. During the culture of Cattleya hybrida, the other aim was how to prevent root rot of Cattleya hybrida. The results showed that lower concentrations NAA could promote water-cultivated-root to grow, the best concentration of NAA was 5mg/L for the induction of root. The reasons causing root rot were that plants could not inhale enough oxygen, the NAA concentration was too higher, or the algae growth. Not using Pharmacy, reducing the concentration of NAA, or changing water usually would prevent root rot. KC nutrition was a better nutrition for Cattleya hybrida. |
