摘要
为明确设施农业土壤农膜残留特征,采用大田监测的方法调查了扬州市广陵区6个设施农业监测点土壤中的农膜残留量。结果表明:2018年、2019年、2020年、2021年广陵区土壤农膜残留量平均值依次为1.635、2.010、1.005、0.600 kg/hm^(2),变化区间依次为0.240~3.315、0.525~6.570、0.585~1.365、0.390~0.810 kg/hm^(2)。其中,种植西瓜的土壤4年农膜残留量依次为1.575、1.620、1.575、1.425 kg/hm^(2),种植番茄的土壤4年农膜残留量依次为3.315、1.230、1.200、1.305 kg/hm^(2),种植茄子的土壤4年农膜残留量依次为0.150、0.750、0.660、1.875 kg/hm^(2)。可知,广陵区设施农业土壤的农膜残留量总体较少,需要从宣传引导、技术支撑、政府管理等途径强化农膜残留管理。
In order to clarify the characteristics of agricultural film residues in soil of facility agriculture,a field monitoring method was used to investigate the amount of agricultural film residues in soil of 6 facility agriculture monitoring points in Guangling District,Yangzhou City.The results showed that the average amount of agricultural film residues in soil in Guangling District in 2018,2019,2020,and 2021 was 1.635,2.010,1.005,0.600 kg/hm^(2),with variation intervals of 0.240-3.315,0.525-6.570,0.585-1.365,0.390-0.810 kg/hm^(2),respectively.Among them,the agricultural film residues of 4 years in the soil planted with watermelon was 1.575,1.620,1.575,1.425 kg/hm^(2),respectively.The agricultural film residues of 4 years in the soil planted with tomato was 3.315,1.230,1.200,1.305 kg/hm^(2),respectively.The agricultural film residues of 4 years in the soil planted with eggplant was 0.150,0.750,0.660,1.875 kg/hm^(2),respectively.It could be seen that the total amount of agricultural film residues in the agricultural soil of Guangling District was relatively small,and it was necessary to strengthen the management of agricultural film residues through publicity and guidance,technical support,government management,et al.
