After evaporation), germination is smoothly performed in rice a3 'disposed at a uniform interval on the paddy field b'.
- the splitting step (S4 ') is a step in which the germinated rice (a3') is split, and the rice (a3 ') previously germinated in the rice germination step (S3') is continuously divided to grow.
- the rice wave biodegradation mulching film decomposition step (S5 ') is a step in which the rice wave biodegradation mulching film (a') placed on the rice paddy bottom (b ') is naturally decomposed and extinguished.
- the film (a ') is formed of a chemical synthetic biodegradable plastic as the main material as described above, it is excellent in tensile strength, moisture resistance, and biodegradability, so that it is approximately 70 days in a state of being unfolded on the paddy field (b').
- the decomposition starts by microorganisms. Around 120 days, that is, 90% or more of biodegradation is completed before harvesting in earnest.
- the advantage is that it does not cause problems due to vinyl collection or problems caused by environmental pollution.
- rice (a3 ') is not decomposed until the split is completed in earnest, it is possible to prevent unnecessary weeds from growing on the paddy field (b'), and thus it is necessary to separate the time required for separate weeding operations. The effect can be eliminated.
