Effects of Fertilization on Bed Seedling of Juglans mandshurica

Objective ] Effects of fertilization on bed seedling of Juglans mandshurica were studied , which were achieved the purpose of cultiva- ting high quality seedling. Method] This paper studied the effects of different fertilizer type and rate on stem, root growth and other characteris- tics in bed seedling of J. man＆hurica. Result ] The results showed that the seedling height, ground diameter, main root length, lateral root number and other characteristics were higher than other treatments, when the urea 15 g/m2 and potassium dihydrogen phosphate 15 g,/m2 were applied. This fertilization was conducive to the cultivation of high quality seedling. Conclusion] The overall quality of the seedlings can be opti- mal when the urea 15 g/m2 and potassium dihy-drogen phosphate 15 g/m2 were applied.
