不同生长状况的卡特兰植株营养元素研究
The Nutrient Elements of Different Growth Conditions of Cattleya hybrida
摘要
Abstract
To discuss the reasons of poor growth of Cattleya hybrida, the nutrient elements contents of its leaves and pseudobulbs on different growth conditions were studied, the pH and EC values of leaching solution of cultivation substrate were also detected. The results showed that the contents of K, Ca, Mg, Mn, Zn, Fe, Cu and Mo in poor growth plants were increased significantly with higher pH and EC values of the leaching solution. It was indicated that salt accumulation might be the main reason of poor growth. Therefore, industrial cultivation of C. hybrida was suggested to apply loose substrate, fertilization should not be too much or too thick, and more rain water was recommended.关键词
