A METHOD FOR APPLYING PLASTIC SOIL MULCH

摘要

The present invention provides a novel method for applying liquid plasticpolymers to soil surfaces in order to form a continuous membrane film for soilmulch. The method related to in the present invention comprises: a) smoothingand saturating the soil surface, b) coating the said soil with plastic coatsby spraying an appropriate polymer formulation for forming said plastic coatson said soil by spraying means, wherein the polymer formulation is applied inat least two coats, first a basic coat consisting of a diluted formulation ofthe polymer and successively other coats consisting up to 40 % polymer andwherein the spraying means are comprised of a sprayer unit consisting of aboom whose spraying line is mounted with flat fan nozzles placed at shortdistances apart. The plastic mulch produced by the method of the presentinvention is useful particularly for enhancing crop production, disinfestationof soil by solarization and prevention of soil erosion.
