Plastic sheet for soil mulching on cotton.

摘要

Plastic sheet for soil mulching on cotton. The plastic sheet intended for floor covering for growing cotton, obtainable by blown cylindrical or linear mold and during the production process itself are made on the same a number of determinants cuts longitudinal openings (3), in combination with excellent elasticity and strength of the material in the sheet (1) is made, enables automatic control of soil aeration covering said sheet (1), and that when this heated by heat effect, the openings (3) expands increasing amplitude and hence increasing ventilation of the covered area, while when the sheet (1) is contracted by the cold, the openings (3) decrease in amplitude, thereby decreasing the ventilation area or floor (4) covered.
