[Objective] The objective of the study is to investigate the effect of the liquid film mulching in ridge and furrow planting conditions in order to provide theoretical support for the selection of the high-yield planting pattern in dry land. [Methods] Liquid film and plastic film mulching were applied in field plot conditions compared with no-film mulching planting in different tillage conditions. [Results] Compared to no-film mulching, the covered planting in ridge and furrow planting conditions increased markedly soil moisture in 0 to 40 cm profile, and increased soil temperature in 5 cm, 10 cm profile in the early stage of maize growth, and covered planting promoted the early stage growth of maize, increased the maize yield remarkably and improved the water use efficiency(WUE)(p<0.05). With the extension of covering time, the effects of harvesting water and keeping warm in plastic film mulching and liquid film mulching conditions weakened gradually. In the condition of less precipitation in pre-experiment, the collection of rain of furrow cultivation was not obvious, but warming effect was obvious. [Conclusion] The effects of the liquid film mulching planting were poorer than the plastic film mulching planting, and were superior to the no-film mulching planting in terms of harvesting water, keeping warm and increasing production. Considered the problem of “white pollution” of plastic film mulching planting, the liquid film mulching in furrow and ridge planting conditions is an ideal dry land covering cultivation technique.
