Abstract
|
|
|
|
With the cultivated mulberry plant which feeds silkworm on its leaves in sericulture, the measuring methods of biomass of terrestrial organs were compared and the annual net productivity was estimated. The measurement of the standing crops by means of allometric method on basis of relation between the parameter D^2_30H, square of the diameter of the branch on 30㎝ high above ground(D^2_30) multiplied by its height(H), and the amount of leaves(W_L) or of branch(W_s) was more accurate than other methods on basis of correlation between a character of the branch such as H, D_30 or D^2_30 and W_L or W_s. The estimate of value of the net productivity of terrestrial parts of mulberry was 9.06-12.54 ton/ha·year, which was similar to that obtained from secondary forests in cool temperate zone.
