Study on the changes of seedling biomass of Introduction Fast-growing Poplar

摘要

With the introduction of four poplar varieties as the research object, in the growth period, the density of 30cm x 40cm biomass of seedlings were studied. The biomass of different organs of different varieties at seedling stage in different periods of change process, it can be seen that different varieties of the same organ is not the same in different periods of change, To estimate the biomass of each type during different periods, it can play a guiding role on nursery stock production.
