摘要: 对地膜穴播、膜侧沟播、露地条播冬小麦主要农艺性状、下一代幼苗性状的研究,结果表明:地膜覆盖栽培可使单株分蘖数,穗粒数,穗粒重,单产增加,但分蘖成穗率,根/冠比小,基部节间延长,抗倒伏性降低;灌浆早、灌浆速率快,种子成熟早、种子生命力旺盛,下一代幼苗期单株干重、耐寒、耐旱、耐高温能力较强。

Abstract: The main agricultural characters of winter wheats and the coming generation were studied by planting in drilling ,bunch planting with plastic film and gouge planting with plastic film. The results indicated that planting by plastic film may lead to higher tillering ,grain numbers /ear,grain weight/ear and the increase of yield of per unit area,but the rate of spike-bearing of tillering,root-shoot ratio were lowered,as well as the lodge-resistant character due to the longer distance betweet plote.The seeds ripen ahead and activity of the seeds are stronger because grain-filling is earlier and the rate of grain-filling is quicker. The dry weight of per individual are higher,and cold ,drought and high temperature resistance are stronger.
