本文通过不同施肥量对毛白杨苗期生长的相关关系,系统地研究了施肥与其整体生物量,施肥与苗木各生长指标关系,以及它们之间生物量幂函数的关系,并通过回归的方程的运算,得出它们之间相应的计算公式。为培育毛白杨壮苗的合理施肥,提供了新的途径和方法,同时也为毛白杨苗木生产标准化,提供了理论根据。
In this paper, the relationship between fertilization and its total biomass, fertilization and growth index of seedlings was systematically studied through the relationship between the different fertilization rates and the growth of Populus tomentosa. The relationship between biomass power function and the relationship between fertilization and biomass power function was studied systematically. Computing, draw the corresponding formula between them. In order to cultivate Populus tomentosa seedlings fertilization, provide a new way and method, but also for poplar seedling production standardization, provides a theoretical basis.
