摘　　要：A feld study was set up to compare dry matter accumulation and grain yield of 3 different types of flm mulching, namely FFC （full flm muched on tiny ridges covered with soil）, PFC （full flm muched covered with soil）, and PF （full flm muched with no cover）. The experiment was laid out in a complete random design with 3 replications at north-west （34°40′N, 105°06′E） of China. This study determined that （1） flm mulching treatment increased leaf area and dry matter accumulation of oil fax in semi-arid areas; （2） accu-mulation of dry matter under PFC treatment was markedly higher than other treatments except anthesis stage; （3） average grain yield of oil fax under flm mulching treatment was 52.67%-60.33% higher than fat plot without mulched or ridge （CK） treatment; （4） grain yield of oil fax was substantially correlated with plant height, grain number and 1,000 kernels weight. This study demonstrated that flm mulching has signifcant effects on crop grain yield improvement in the northwest of China.A field study was set up to compare dry matter accumulation and grain yield of 3 different types of film mulching, namely FFC(full film muched on tiny ridges covered with soil), PFC(full film muched covered with soil), and PF(full film muched with no cover).
