摘 要:采用大田随机区组试验设计研究了地膜、纸膜、麦秸、油菜壳、青草五种不同覆盖物覆盖对旱作水稻田间生态环境及产量的影响。结果表明:油菜壳、麦秸、青草覆盖处理具有良好的隔热、吸水、保水作用,增加土壤的含水量,促进旱作水稻生长,有很好的增产效果,较对照分别增产1035.5kg/hm2、918.8 kg/hm2、566.9 kg/hm2,增幅为19.7%、17.5%、10.8%,增产达极显著水平;地膜覆盖具有增温、保水效果,较对照增产377.9kg/hm2,增幅为7.2%,增产达显著水平;纸膜覆盖处理较对照增产不显著。By using block design the effects of the plastic film, the paper, the wheat straw, the rape shell and the grass coverings on the ecological environment and yield of rice cultivated in aerobic soil were studied. The results obtained showed that the ability of heat insulation and absorbing water and water maintenance Rape shell were effectively increasedby, the content of soil water was increased, the growth of rice cultivated in aerobic soil was accelerated and the yield was significantly increased where treatment was covered by the plastic film, the paper, the wheat straw, the rape shell and the grass ,the yield was increased by 1035.5kg/hm^2 ,918.8 kg/hm^2 ,566.9 kg/hm^2 ,the percentage was increased by 19.7% ,17.5% ,10.8%. The yield of plastic film covered treatment increased by 377.9kg/hm^2, the by percentage 7.2%. The effect of paper covered was not significant.
