Abstract:
Using tomato、carrot and garlic as materials,the yield and selenium,inorganic selenium and organic selenium contens were measured by praying different Na2SeO3 on tomato,carrot and garlic leaves.The results showed that the organic selenium conversion rate reduced as the selenium mass concentration raises.When spray 100 mg/L Na2SeO3 selenium on the tomato,carrot,garlic the organic selenium enrichment were 7.83 times,8.53 times,2.85 times of the control respectively,tomato’s selenium enrichment was the highest.But when spray 500 mg/L Na2SeO3 selenium on garlic leaves,its organic selenium enrichment was 4.70 times of the control,and under such condition the garlic had the highest ability of selenium enrichment.The yield of tomato and carrot could be raised when they were sprayed ≤1.0 mg/L Na2SeO3 times of the control and so did the garlic when it was sprayed ≤10 mg/L Na2SeO3,when the Na2SeO3 mass concentration raises the yield and organic selenium content of the three vegetables would reduce.According to the experiment results,the yield of tomato and carrot could be raised if they were sprayed Na2SeO3 0.5～1.0 mg/L and so did the garlic if the selenium mass concentration ≤10 mg/L.
