摘  要：
采用盆栽试验,模拟除草剂土壤残留环境,研究土壤中异噁草松残留对甜菜生长的影响,阐明利用生物炭降低残留药害、促进甜菜生长的作用。结果表明:土壤中异噁草松残留达到0.12 mg·kg-1,甜菜生长受抑制,并随残留量增加而逐渐加重;当土壤中异噁草松浓度大于0.48 mg·kg-1,幼苗初期生长受重度药害抑制率达100%;施入一定量生物炭后,幼苗受药害症状普遍减轻或不受药害,植株生长旺盛,根冠比增加,根系形态结构改善,含糖量平均增加1.10%,与未施炭处理差异显著。试验结果表明,土壤中施入一定量的生物炭,能够降低除草剂残留对甜菜生长的抑制作用,对甜菜生长有明显的促进作用。

摘  要：
Effects of biological carbon(bio-char)on sugar beet growth were studied by pot experiments simulating long residual herbicide residues in soil environment. The results showed that the safety threshold of sugar beet growth with clomazone residual was 0.12 mg·kg-1, and beyond this value, sugar beet growth was in inhibition with clomazone residues increased gradually; Early seedling growth under severe phyto-toxicity inhibition rate reached 100% when clomazone concentration was greater than 0.48 mg·kg-1; Seedlings subjected to injury sym-ptoms generally reduced to no phytotoxicity after put into a certain amount of bio-car in soil, the plant growth and root shoot ratio increased. Sugar beet root tuber yield and total sugar yield were influenced after applying carbon, sugar content increased 1.10%, which showed significant difference compared with CK. It explained that the bio-char could promote the growth of sugar beet. Applying biochar to soil could reduce the biological hazardous taken by clomazone residues within certain scope.
