Abstract：Under field cultivation and spring sowing conditions , the experiments were carried out to study the plant traits, dry matter accumulation dynamics and pod maturity and plumpness under film mulching and open field planting patterns .The results showed that , compared with open field cultivation , the main steam height, lateral branch length, number of leaves on main steam and leaf area index under film mulching treat-ment were significantly increased at pot -setting stage .Meanwhile , the dry matter accumulation of whole plant and pod under film mulching treatment were significantly increased at yield -forming stage , which could pro-mote pod development , ahead of rapid accumulation period for one week , and the period of whole plant was basically the same as that of the pod .Film mulching cultivation increased the number of pod per plant , 100-pod weight , harvest index , kernel percent , pod and kernel maturity and plumpness , and the yield increased by 25.22%.Comprehensive evaluation showed that , film mulching cultivation could coordinate the vegetative and reproductive growth of peanut , and increase pod yield mainly through increasing 100-pod weight , pod and kernel maturity and plumpness .
