Effects of Soaking Time and Seeding Densities on Germination and Growth of Semiliquidmbar cathayensis

To improve the quality of Semiliquidmbar cathayensis seedlings, the effects of soaking time and seeding density were studied on seed germination and seedling growth. A total of 5 kinds of immersion time were set in 0 h, 12 h, 24 h, 48 h, and 60 h to observe the germination rate and germination potential of the field garden. A total of 4 different seeding density were set with 280 plants·m^-2, 66 plants·m^-2, 44 plants·m^-2 and 33 plants·m^-2 to Measure seedling height, ground diameter, main root length, primary lateral root number and biomass of annual seedlings. The results showed that the suitable soaking time of seeds was 48 h, combined with the best quality and quantity of seedlings, and the suitable seeding density was 44 plants·m^-2.
