摘　　要：以泰花8号为试验材料,分别设置JM1(0.01 mm强化耐厚膜)、JM2(0.01 mm PPC膜)、JM3(0.01 mm PLA膜)、JM4(0.008 mm PLA膜)、JM5(0.006 mm PLA膜)、JM6(0.01 mm PBAT膜)和CK1(普通白膜)、CK2(普通黑膜)、CK3(露地栽培)处理,研究生物降解膜对花生产量以及收获后田间土壤污染的影响。结果表明:花生收获前,JM2、JM4、JM5和JM6膜型自然降解均达4级(70%)以上,而JM1、CK1和CK2在土壤中仍保持完好。CK1、CK2、JM1对花生生育促进和增产效果均最好,JM3和JM2稍次。通过对JM2、JM3、JM6和CK3土壤样品进行全元素检测和热裂解分析,检测结果中重金属元素均处于安全范围内,且JM2、JM3、JM6土壤样品中主要成分均为CO2。The effects of biodegradable plastic mulching on peanut yield and soil pollution after crop harvest were studied.Taking Taihua-8 as the experimental material,different types of mulch as:0.01 mm enhanced thick film(JM1),0.01 mm PPC black degradation film(JM2),0.01 mm PLA film(JM3),0.008 mm PLA film(JM4),0.006 mm PLA film(JM5),0.01 mm PBAT biodegradation film(JM6),common white film(CK1)、common black film(CK2),and open culture(CK3)were respectively treated.The results showed that under natural condition,the degradation of JM2、JM4、JM5 and JM6 were all reached grade IV(70%)before peanut harvest,while JM1,CK1 and CK2 were still intact in the soil.CK1,CK2,JM1 had the best effect on peanut growth and yield,JM2 and JM3 were slightly inferior.Through the total elements detection and pyrolysis analysis on JM2,JM3,JM6 and CK3 soil samples,the heavy metal elements were in the safe range,and the main components of JM2,JM3 and JM6 in soil samples were CO2.
