The Effects of Biological Agents on Survival, Biomass and Foliar Nutrient Concentrations of Mongolian Pine (Pinus sylvestris var. mongolica) Seedlings Planted on Keerqin Sandy Lands, China

Abstract:

Abstract: The experiments were conducted by planting in the field of 2 year-old Mongolian Pine (Pinus sylvstris var. mongolica) seedlings processed with Pt mycorrhizal agents, ABT rooting powder, HRC water-absorbing agent and GRR plant development and growth regulator. The results were as follows: (1) Pt₃ and ABT had significantly increased survival rates of seedlings, which were 29.3%, 23.6% and 9.4% higher than that of controlled seedlings, respectively.; (2) Pt₃ and ABT had enhanced the growth of the fine root(<2mm), which were 34.72 and 15.18 cm longer than that of controlled seedlings; the regression analysis had showed that fine roots quantity was positively related to seedling survival rate; (3) The growth indexes of the average individuals with Pt₃, ABT and HRC were higher than those of untreated seedlings; (4) Pt₃ and ABT also effectively promoted the absorption of main nutrients such as N, P, and K in the needle of seedling.
