中文摘要:
      为比较秋季覆膜与春季覆膜的保墒增产效果,在辽宁西部的建平县坡耕地上布置试验,对春季覆膜、秋季覆膜旱地农田土壤墒情及春玉米产量差异进行了比较研究。结果表明:与不覆膜相比,春季覆膜、秋季覆膜处理春播前0~15 cm土层土壤墒情增加;秋季覆膜、春季覆膜和未覆膜(对照)处理产量分别为5814.6 kg/hm2、4997.33 kg/hm2和4069.46 kg/hm2,秋季覆膜、春季覆膜比对照增产30.01%和18.57%,水分利用效率提高了18.45%和29.43%。
英文摘要:
      In order to make clear the effects of plastic film-mulching in autumn and in early spring on soil water content and spring maize yield of dryland in western Liaoning,field plot experiments were conducted in Jianping Country of Liaoning Province.The results showed that plastic film-mulching in early spring and in autumn before sowing could improve the water-holding capability of soil in the depth of 15 cm.The average yield of spring maize with plastic-film mulching in autumn and in early spring and traditional cultivation was 5 814.6 kg/hm2,4 997.33 kg/hm2 and 4 069.46 kg/hm2.Compared to the traditional cultivation,plastic film-mulching in early spring and in autumn could increase the average yield by 30.01% and 18.57% and increase water use efficiency by 18.45% and 29.43% respectively.
