摘要

PROBLEM TO BE SOLVED: To provide biodegradable multi-films for agriculture with excellent convenience of disposal without imparting a dirty impression in disposal aspects; and to provide disposal methods of used biodegradable multi-film for agriculture.SOLUTION: A biodegradable multi-film for agriculture of the present invention has biodegradability, has a colored layer which is colored in blackish brown, and, preferably, has the average transmittance in the visible light range from 400 nm to 700 nm of 35% or less. In the disposal method of a used biodegradable multi-film for agriculture of the present invention, when disposed after multi-cultivation using a biodegradable multi-film for agriculture having biodegradability at the time of spreading on the field and having a colored layer colored in blackish brown, in the state that the biodegradable multi-film for agriculture is crushed into small pieces 1 and dispersed in a soil 2, the small pieces 1 of the biodegradable multi-film for agriculture dispersed throughout the field is difficult to visually distinguish from the soil 2.SELECTED DRAWING: Figure 1
