不同处理对红掌水生根系的诱导效果研究

目的]探寻诱导红掌(Anthurium andraeanum)水生根的最佳方法。方法]采用不同方法浸泡、覆盖红掌根系。结果]用清水培养烂根少,发根快,但是叶片失绿,老叶枯萎;单纯用营养液培养,根系腐烂严重,但叶片浓绿、长势良好;综合叶片和根系的生长情况,在清水中加入碎花泥覆盖根系,并适时滴加营养液,能减轻根系腐烂,并有效地改善叶片的营养,保持株型。结论]该研究可为红掌生产提供技术参考。

Effect of Different Treatments on Induction of Water Root System of Anthurium andraeanum

Objective ] The study aimed to obtain the optimum method to induct water root system of Anthurium andraeanum. Method] Dif- ferent methods were adopted to soak or cover the root system of A. andraeanum. Result] The results showed that it reduced root rotting when A. andraeanum was cultured in water, but it led to chlorosis. It caused the root rot grave that cultured with nutrient solution, but the leaves were green and growing well. Comprehensive analyzing the growth of root and leaf, culturing with water and using fragment of phenol aldehyde foam to cover the root, and adding nutrient solution regularly, can reduce the root rot and effectively improve the nutrition of leaves. Conclu- sion] The study can provide teehniea reference for production of A. andraeanum.
