摘　　要：研究超薄生物降解地膜应用于有机水稻生产,生物降解地膜的降解特性及其对稻田杂草、用水量、水稻产量和经济效益的影响。结果表明,黑色生物降解地膜(QTH)可以有效地保温保墒,并有效抑制杂草;同时,显著地提高了水稻的结实率、糙米率和精米率,使产量提高了14%,蛋白质含量提高了9.38%。This paper studied the application of ultra-thin biodegradable mulch film to organic rice production,the degradation characteristics of biodegradable mulch film and its effects on weeds,water consumption,rice yield and economic benefits in rice field.The result showed that the black biodegradable mulch could effectively maintain heat and moisture,and effectively inhibit weeds.At the same time,the rice seed setting rate,brown rice rate and white rice rate were significantly improved.Rice yield increased by 14%and protein content by 9.38%.
