摘要
在葡萄埋土防寒区,采用可降解液态膜喷施葡萄园土壤及葡萄枝条的方式代替传统埋土防寒。在保障葡萄植株安全越冬以及预防倒春寒的同时,通过检测葡萄果实、枝条及土壤中的污染物残留,探究可降解液态膜对葡萄植株及土壤的污染情况。结果表明,可降解液态膜在越冬前喷施在土壤和植株上,可在180 d内自然降解;对重金属含量的检测显示,连续5年冬季使用及春季短期使用可降解液态膜的土壤中,砷、铬、镉、铅和镍的含量均低于国家标准,且短期内可降解液态膜的使用显著降低了土壤中的铬、铅和镍的含量;连续5年冬季使用可降解液态膜地块种植的葡萄果实中未检出镉、铅,春季使用可降解液态膜的葡萄枝条中镉、铅的含量与对照无明显差别;可降解液态膜的使用同样无苯并[α]芘污染风险。以上结果表明,田间正常使用可降解液态膜不具有砷、铬、镉、铅、镍和苯并[α]芘污染的风险。
In the cold area of grapevine buried soil,the Biodegradable liquid film(BLF)was applied to the vineyard soil and vine branches instead of the traditional buried soil for cold protection.By detecting the residue of pollutants in grape fruits,branches and soil,the pollutant residuces of BLF on grapevine plants and soil were investigated.The results showed that BLF was sprayed on soil and plants in winter,which could be basically degraded naturally within 180 days;The test of heavy metal content showed that the content of arsenic,chromium,cadmium,lead and nickel in soil using BLF for five consecutive years in winter and for a short period in spring were lower than the national standard,and the use of BLF significantly reduced the content of chromium,lead,and nickel in soil in the short term;cadmium and lead were not detected in grape fruits using BLF for five consecutive years in winter,and there was no significant difference in the content of cadmium and lead in grape branches using BLF inspring compared to the control;the use of BLF was also without the risk of benzene[α]pyrene pollution.The above results indicate that the field use of BLF does not have the risk of contamination by arsenic,chromium,cadmium,lead,nickel and benzo[α]pyrene.
