Abstract: In order to discuss peanut cultivation patterns under mulched drip irrigation in Xinjiang areas.A new peanut cultivar Huayu 36 was used as testing material and was planted in 2015. Based on the methods of field experiments and laboratory analysis,we analyzed the effects of two cultivation patterns,including uncovering plastic film(UPF)and mulching plastic film(MPF)on growth development,dry matter accumulation dynamic changes and pod yield of peanut. The results showed that there were some differences among the main agronomic traits,the dry and fresh weight dynamic changes per organ and the total pod yield for Huayu 36 under UPF and MPF pattern,but the differences were not significant. Compared with MPF pattern,UPF pattern contributes to enhance the main stem height,lateral branch length,branch number,main stem green leaves number and main stem nodes number of peanut and so on. Meanwhile,in earlier stage of UPF,the fresh weight and dry matter weight of roots,stems and leaves were higher than MPF's,but the dry matter weight of pods were lower than MPF's,and in the condition of UPF, the pod yield cut down 871.3 kg/hma,the yield reduction rate was 8.1%. Therefore,under the premise of considering environmental protection and peanut planting benefit,UPF is a feasible cultivation pattern,this pattern not only better utilize positive effect in earlier stage of plastic film,but also enhance the recycling rate of plastic film residue and increase the added value of peanut straws to some extent.
