【Abstract】 Heavenly bamboo seedling was treated with different nutrient solutions and the results showed that it was impossible to increase the growing speed of heavenly bamboo seedling the activity of nitrate reductase and root tip, the contents of chlorophyll,soluble sugar and protein and the water contents of leaf after stressing through the different treatments. The treatment B can distinctively increase the contents of chlorophyll, the activity of nitrate reductase and root tip and the water contents of leaf.
