在春播大田栽培条件下，对比研究了花生覆膜和露地种植方式的植株性状、干物质积累变化动态和荚果的成熟饱满度。结果表明：与露地栽培相比，覆膜栽培花生结荚期的主茎高、侧枝长、主茎绿叶数和叶面积指数显著增加；同时覆膜栽培花生显著增加产量形成期整株和荚果的干物质积累，可促进荚果发育，快速积累期可提前1周左右，荚果干重与整株干重的快速增长期基本一致；覆膜栽培提高花生的单株结果数、百果重、收获指数、出仁率、荚果和籽仁成熟饱满度，增产25．22％。研究认为，覆膜可协调花生营养生长和生殖生长，主要通过增加百果重、荚果及籽仁成熟饱满度提高产量。

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 .
