ABSTRACT:
In water deficit area, judicious use of water is essential for increasing
area under crop production with limited water supply. Film Mulching has been
advocated as an effective means for conserving soil moisture in rice
production. The effects of high density polyethylene (HDPE) film on increasing
rice production, controlling weeds and residue amount of plastic were studied
under five treatments, including 5, 10, 15 and 20 μm thickness as well as bare
cultivation (CK). The results indicated that the HDPE film mulching mode had
significant effects on weed control, soil temperature, soil moisture,
photosynthetic rate, seedling biomass, yield and residues of plastic film.
Combined with economic effect, it showed that the HDPE film of 10 μm is the
best option for rice production.
