Abstract:: The film covering the soil surface increases the soil water content, but sometimes it also hinders the runoff into soil. We have carried out this research in order to study the effect on distribution of soil water and heat for different materials. Results show that water-permeability film has the efficient to increase the soil moisture and temperature during the corn growth period, but that was less than the ordinary film, the soil temperature were 1.09℃ and 2.59℃ more than that of bare land and straw mulch, respectively, but it was 1.55℃ less than ordinary film mulch. The water consumption of water-permeability film mulch was 26.7 mm less than ordinary film mulch. And the moisture of soil covered with water-permeability film was uniformly distributed during the dry season. Corn water use efficiency of the soil covered water-permeability film increased by 8.17 kg/(hm²·mm), 4.50 kg/(hm²·mm), and 3.71 kg/(hm²·mm) than those of the bare land, straw mulch, and ordinary film mulch, respectively.
