Abstract:

Root shoot ratio and healthy index of pumpkin plug seedling in different fertilizer application standard was systemic studied by randomized complete-block design. Root shoot ratio and healthy index of Pansy plug seedling was significantly smaller compared with the control by the application of nitrogen fertilizer.5g/L and 10 g/L of nitrogen fertilizer have no significant difference impact on the root shoot ratio of Pansy plug seedling.5g/L and 10g/L of nitrogen fertilizer produced a coercive effect on the root of Pansy plug seedling ,the inhibition of two levels to the root is approximately equal. Phosphorus and Potassium without a regular and significant effect on the rootshoot ratio of Pansy plug seedling, but to make healthy index of Pansy plug seedling has a certain degree of reduction. Compared with the control ,the root shoot ratio of Pansy plug seedling increased significantly in all seedling age by Microelement fertilizer application, but has no significant effect on healthy index of Pansy plug seedling.
