摘要
以亚麻品种内亚9号为材料,在浏阳市永和镇佳成村污染土壤上种植亚麻,探讨土壤重金属镉对亚麻生长的影响。结果表明,不同地点土壤镉浓度不同,对亚麻的生长(农艺性状及产量)产生了不同影响,在田块11土壤镉含量达8.95 mg/kg的情况下,亚麻原茎产量和种子产量仍分别达4228.45 kg/hm^(2)和456.27 kg/hm^(2),表明亚麻对高浓度Cd耐受性较强。土壤重金属镉含量与亚麻原茎产量、种子产量的相关系数分别为-0.15328、-0.15167,存在一定的负相关性,但相关性不显著。综上,浏阳市永和镇佳成村亚麻种植基地土壤中的重金属镉影响了亚麻的生长,使其产生5种不同的生长类型。
By planting flax in contaminated soil in Jiacheng Village,Yonghe Town,Liuyang City,the effects of soil heavy metal cadmium on flax growth were explored using the flax variety Neiya No.9 as material.The results showed that,in the case of soil cadmium content of 8.95 mg/kg in field 11,the stem yield and seed yield of flax still reached 4228.45 kg/hm^(2)and 456.27 kg/hm^(2),respectively,indicating that flax had strong tolerance to high concentrations of cadmium.Different soil cadmium concentrations in different locations had different effects on the growth(agronomic traits and yield)of flax.the correlation coefficients between soil heavy metal cadmium content and stem yield and seed yield of flax were-0.15328 and-0.15167,respectively.There was a certain negative correlation,but the correlation was not significant.In summary,the soil heavy metal cadmium in the flax planting base in Jiacheng Village,Yonghe Town,Liuyang City,affected the growth of flax,resulting in 5 different growth types.
