Abstract: In order to avoid the reduction of spring maize output caused by low temperature and drought in cold region and explore the suitable film mulching modes, field experiments were conducted from 2012 to 2013 to study the effects of eight plastic film mulching modes on soil moisture, soil temperature and maize yield. The results showed that the film mulching mode of ridge height 5-10 cm and mulching width 50-70 cm could increase soil moisture and keep soil temperature, which could increase the average temperature by 1.5-2.3℃in 0-5 cm soil layer and advance maize tasseling by 6-7 d compared with non-film mulching treatment. The yield of ridge height 10 cm and mulching width 50- 70 cm was significantly higher than that of non- film mulching treatment, and it had no significant difference with the full film mulching on double ridges and flat planting of wide film mulching. The yield of mulching width 50 cm and 70 cm and ridge height 10 cm were 17.9%, 17.1% and 15.6% higher than that of non-film mulching treatment in 2012, and they were 15.5%, 6.4% and 18.2% higher than that of non-film mulching treatment in 2013. On comprehensive consideration of soil moisture, soil temperature and spring maize yield, the plastic film mulching mode of ridge height 5-10 cm and mulching width 50-70 cm was the suitable mulching mode for spring maize planting in this region.
