Abstract

Método de protección de cultivos caracterizado porque comprende la absorción de las radiaciones infrarrojas de la gama de longitud de onda comprendida entre 5 y 15 micras, mediante una película de poliolefina obtenida mediante una mezcla de una poliolefina obtenida mediante una mezcla de una poliolefina a una temperatura superior a su temperatura su fusión con una caolinita esencialmente deshidratada mediante calcinación de un aluminio-silicato hidratado, y porque la caolinita mezcla con la poliolefina está en una proporción de 1 al 15% en peso de dicha poliolefina, conteniendo dicha caolinita del 51 al 57% en peso aproximadamente de sílice, del 40 al 46% en peso de alumina y menos del 3% de impureza.
