摘要
以番茄、胡萝卜、大蒜为试材，研究了叶面喷施不同质量浓度的Na2SeO3对不同蔬菜硒富集及产量的影响。结果表明：叶面喷施硒可以显著提高各蔬菜中全硒、无机硒和有机硒的含量，有机硒转化率随着施硒质量浓度的提高而降低；番茄、胡萝卜和大蒜均喷施质量浓度为100mg／L Na2SeO3时，有机硒的富集分别为对照的7．83、8．53、2．85倍，胡萝卜富硒最高，但当大蒜喷施质量浓度为500mg／LNa2SeO3时，有机硒的富集为对照的4．70倍，大蒜富硒能力强；番茄和胡萝卜在Na2SeO3质量浓度≤1．0mg／L 时和大蒜在Na2SeO3质量浓度≤10mg／I。时，其产量有所增加，当喷施的Na2SeO3质量浓度提高时，各蔬菜产量均有所降低；番茄和胡萝卜叶面喷施硒质量浓度在0．5-1．0mg／L区间，大蒜叶面喷施硒质量浓度≤10mg／L较为适宜，可以有效提高蔬菜有机硒含量和产量。
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 Na2 SeO3 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 ≤l. 0 mg/ L Na2SeO3 times of the control and so did the garlic when it was sprayed ≤10 mg/L Na2SeO3 ,when the Na2 SeO3 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.
