The invention provides a PE mulching film, which comprises a PE film body, which comprises an upper layer, an intermediate layer and a lower layer arranged in turn from top to bottom, and also includes a PE nucleating agent layer and an infrared absorption layer. The PE nucleating agent layer is arranged on the upper surface of the upper layer, and the infrared absorption layer is arranged on the lower surface of the lower layer.Through the application of theThe lower surface is respectively provided with PE nucleating agent layer and infrared absorption layer,PE nucleating agent layer can increase the transmittance of visible light,In this way, the sunlight can effectively pass through the PE film and reach the surface to provide the temperature needed for the growth of crops,At the same time, the infrared absorption layer can absorb the infrared radiation lost from the ground surface,in other words,Through the coordination of PE nucleating agent layer and infrared absorption layer, the results show that the method is simple and effective,Thus, the PE mulching film can achieve better insulation effect,secondly,Through the setting of three layers of PE film body, it can keep good heat preservation effect while taking into account the tensile and toughness properties,At the same time, it can slow down the diffusion of heat.本發明提供了一種PE地膜，包括PE膜本體，PE膜本體包括從上而下依次設置的上層、中間層和下層，還包括PE成核劑層和紅外吸收層，PE成核劑層設置於上層的上表面，紅外吸收層設置於下層的下表面。通過在PE膜本體的上、下表面分別設置PE成核劑層和紅外吸收層，PE成核劑層可以增加可見光的透光率，從而使太陽光有效的透過PE地膜而達到地表給農作物提供生長所需的溫度，同時紅外吸收層可以將地表散失的紅外熱輻射進行吸收，也就是說，通過PE成核劑層和紅外吸收層的協調作用，從而使PE地膜能夠實現較好的保溫效果，其次，通過PE地膜本體三層的設置可以使PE地膜保持較好的保溫效果的同時兼顧拉伸及韌性性能，同時可以減緩熱量的擴散。
