针对西辽河平原年降水量少、季节分布不均、特别是玉米生产中春旱严重等问题，以郑单958和北育288为试材，研究4种不同覆膜方式对春玉米农艺性状和产量的影响.结果表明，全膜覆盖提高了玉米株高、茎粗、穗长和穗粗，百粒重增加，进而提高产量.郑单958和北育288全膜覆盖处理的产量比不覆膜处理分别增产22.77%和17.34%.

In order to meet of water requirement of maize at the situation of limited and unevenly distributed rainfall in Liaohe plain, specially the problem of serious spring drought during the growing period of maize, the Zhengdan 958 and Beiyu 288 were used as the test material, studied the effects of four different plastic-film mulching modes on agronomic traits and yield of spring maize, The results showed that, The treatment of full plastic-film mulching modes increase plant height, stem perimeter, ear length, ear width and 100-grain weight, increased yield. The yield of Zhengdan 958 and Beiyu 288 of full plastic-film mulching modes increased respectively by 22.77% and 17.34%, compared to the treatment of non-plastic-film mulching modes.
