ABSTRACT:
The invention relates to polymeric mulch sheets and mulch films for use in agriculture. These filter out a large part of the solar radiation which promotes photosynthesis and plant development, and transmits enough solar radiation so as to heat the soil beneath such films. The sheets or films have a green color and transmit about 15-30 percent of the energy in the green range, and a large percentage of the energy in the 730 to 1100 nm range. Such mulch films substantially reduce weed growth. The invention further relates to a method of plant cultivation where the plants are cultivated, using sheets or films according to the invention.
