摘要
以吉林省中部地区水稻土为试验土壤,通过不同施锌量的盆栽试验,研究了锌在水稻各生育时期不同器官的运转规律。结果表明,各器官含锌量均随施锌水平的提高而增加,施锌可以改变同一生育时期锌在各器官的分配比例,锌在各器官的积累存在明显的相关性,成熟期锌在植株体内的分布由高到低依次为:根、叶、茎、穗、稻谷、糙米、颖壳。
The distribution regulation of zinc content in various organs at different growth stages of rice was investigated in pot culture with paddy soil in the middle area of Jilin province.The result showed that zinc content in various organs increased with the zinc treatment increased.The distribution rate of zinc in the organs could be changed by zinc treatment at the same growth stage,and zinc accumulation in the organs had significantly correlation.The distribution regulation of zinc content at mature stage was root,leaf,stem,ear,rice,brown rice,rice shell.
