Researching on the Nutrition Element Content Changes of Vernicia montana Seed and Seedling in Seed Soaking Times

This paper took Vernicia montana seedlings as research objects, and compared with nutrient elements in different disposing methods through field experiments and analyses in door. The results showed that: After soaking of V. montana seeds, P, Mg, Mn, Cu, Zn content of all the tissues were increased, and the N, K, Ca, Fe, Al, S nutrient content showed a trend of decrease. Among of them, the rate of change of P, K, Mg, Cu, Zn was more than 10%. The major nutrient elements such as C, N, P, and K showed wide change range. Seed soaking or not, N and P content decreased first and then increased, while K content showed a different trend, which was increased first and then decreased.
