基肥对白桦(Betula platyphylla)幼苗生长影响的研究
Effect of Base Fertilizer on the Growth of ContainerSeedling of White Birth(Betula Platyphylla)
摘要
Abstract
In order to determine the base fertilizer for container seedling of white birch(Betula platyphylla Suk),the optimal formula was constructed applying the method of orthogonal test design by fertilizing experiments of adding different dose of urea(N),calcium superphosphate(P),and potassium sulfate(K)to seeding matrix.The responses of annual seedling height(H),root-collar diameter(D)and aboveground biomass(B)to additive amount of N,P and K fertilizer were different.With the additive amount of N and K increasing,H was in a parabolic dune with an initial increasing trend and followed by a decreasing trend.With the P increasing,the amount of H showed an S type curve with initial increasing and later following by a constant trend.The optimal formula of N,P and K for container seedling height growth was 1.3104,0.3294 and 0.7604 g·stem-1,respectively.With the element of N,P and K increasing,the D presented an S type curve trend of initial increase followed by a constant.The optimal formula of N,P and K for container seedling diameter growth was 1.9656,0.8470 and 0.7604 g·stem-1,respectively.The changing trend of B was the initial increase followed by a constant with N increasing.But as P and K increase,the changing tendency of B showed the parabolic types of the initial increase followed by a decrease.The optimal formula of N,P and K for container seedling B growth was 1.9656,0.3294 and 0.7604 g·stem-1,respectively.In summary,the optimal formula of N,P and K for container seedling was 1.3104,0.3294 and 0.7604 g·stem-1,respectively.关键词
