Abstract: Soil moisture and temperature during different growth period of maize with the full plasticfilm mulching on double ridges with furrow(T1),flat film(T2)and open flat(not covered,CK)was compared,the effects of T1 on soil moisture and temperature in dry farming maize was studied through field experiment.The results showed that the average moisture of 0-200cm soil layer in T1,during the whole growth period,was higher 1.0 percentage points and 0.9 percentage points than that of T2 and CK,and 0.9 percentage points and 1.5 percentage points than that of T2 and CK from emergence to silking stage.Among the treatments,the maximum difference of the average moisture of 0-200cm soil layer occurred at seven leaf stage,and that of T1 was higher 1.4 percentage points and 2.6 percentage points than that of T2 and CK.The minimum difference occurred at jointing stage,and that of T1 was higher 0.4 percentage points and 0.3 percentage points than that of T2 and CK.The average moisture in 0-40cm of each layer in T1 was higher 1 percentage points and 1.7 percentage points than that of T2 and CK,with peak value 1.2 percentage points and 2.2 percentage points in 0-20cm.In addition,that of T1 was higher 0.9 percentage points and 1.3 percentage points than that of T2 and CK in 30-40cm,that of T1 was higher 0.7 percentage points than that of T2 and lower 1.0 percentage points than that of CK in 80-200cm.The average temperature in 0-40cm of each layer during the whole growth period in T1 was higher 0.7℃ and 2.7℃ than that of T2 and CK,with peak value 0.6℃ and 5.1℃ at seedling stage.The results indicated that the mode of full plasticfilm mulching on double ridges with furrow could improve soil moisture and temperature obviously,which was high efficiency planting mode in dry farming maize area.

Key words: Dryland maize, Full plastic film mulching on double ridges with furrow, Plastic film mulching mode, Soil moisture, Soil temperature
