摘 要:为了解决白桦容器育苗中的基质底肥问题,采用正交试验设计方法,通过増施不同剂量的尿素(N)、过磷酸钙(P)和硫酸钾(K)基肥试验,筛选适宜的白桦容器育苗基质增施基肥方案.当年生白桦播种苗苗高(H)、地径(D)和地上生物量(B)对増施N、P和K的反應均不相同.随着N和K的增加,H表现出初始增加随后降低的抛物线式变化趋势,而随着P增加,H表现出初始增加随后稳定的S型曲线变化趋势;适宜H增长的N、P、K配方分别为1.310 4、0.329 4、0.760 4 g/株.随着N、P和K的增加,D均表现出初始增加随后稳定的S型曲线变化趋势;适宜D增长的N、P和K配方分别为1.965 6、0.847 0和0.760 4 g/株.随着N增加,B表现出初始增加随后稳定的S型曲线变化趋势,而随着P和K增加,B表现出初始增加随后降低的抛物线式变化趋势;适宜B增长的N、P、K配方为1.9656、0.3294和0.7604g/株.综合来看,白桦容器育苗时可在育苗基质中添加N、P和K分别为1.310 4、0.329 4和0.760 4 g/株.

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.
