| 摘 要： | 地膜残留对农田土壤安全和作物产量具有极大的威胁,掌握作物农田地膜残留特征可为采取高效治理措施提供重要依据。本文选取新源县主要覆膜田制种玉米田,并选取覆膜0-5年、6-10年、11-15年和16-20年地块进行地膜残留取样。结果表明：随着覆膜年限的增加,新源县制种玉米田残膜含量呈显著增加趋势,覆膜16-20年最大,可达83 kg/hm2。对比各土层残膜占比,上层(0-10cm)土层一直最高,中层(10-20cm)土层次之,下层(0-10cm)土层最低。

| Abstract: | Plastic film residue is a great threat to farmland soil safety and crop yield. Mastering the characteristics of plastic film residue in different crops can provide an important basis for taking effective control measures. In this paper, the main plastic film mulched corn fields in Xinyuan county were selected, and the plastic film mulched plots of 0-5 years, 6-10 years, 11-15 years and 16-20 years were selected for plastic film residue sampling. The results showed that: with the increase of film mulching years, the residual film content of seed production maize field in Xinyuan county showed a significant increase trend, and the maximum was 83 kg / hm2 in 16-20 years. The proportion of residual film in the upper layer (0-10cm) was the highest, the middle layer (10-20cm) was the highest, and the lower layer (0-10cm) was the lowest. |
