| 摘 要： | 以叶面施硒和土壤施硒2 种方式处理芹菜品种.结果表明:低浓度的硒能够促进植物的生长发育,芹菜产量提高,硒浓度较高时,产量降低.芹菜含硒量随着硒处理浓度的增大而提高,但无机硒转化为有机硒的比率下降.从获得生物产量和高硒产品的目的出发,芹菜的补硒技术叶面喷施浓度为<60 mg/L,土壤施用硒肥为0.01 g/m2(即0.1 kg/hm2).

| Abstract: | Celery was conducted using two methods of putting sodium selenite in soil and on celery leaf.The results showed that selenium at low concentration can promote plant growth,and yield of celery was increased.But athigh concentration it could lead an decrease.selenium contents in celery was increased with anincreasing concentration of sodium selenite.But the efficiency of transforming selenium into organ slowed down.In order to get a high biological yield and a high selenium production,it could be concluded th... |
