几种蔬菜不同水平硒肥试验

The trial of vegetable cultivation by different levels of selenium fertilization

【目的】试探几种蔬菜富硒效果,为富硒蔬菜生产提供参考依据。【方法】以本地区域日常食用的几种蔬菜为材料,采用根外追肥——叶面喷施的方式,进行不同水平的硒肥试验。【结果】所有喷施硒肥处理的蔬菜植株硒含量均比对照有不同程度的提高,提高倍数为8至32倍之间;用"康熙宝"30ml/45kg、40ml/45kg喷两次或用"有机硒素"200g/60kg喷一次都能生产富硒蔬菜,效果比较明显。【结论】添加外源硒肥"康熙宝"或"有机硒素"可以有效地改善蔬菜的品质、提高蔬菜有机硒的含量,生产出富硒蔬菜。

【 Objective】 Conduct the trial of vegetable cultivation by different levels of selenium fertilization, provide a reference basis for selenium - rich vegetables production.【 Method】 Applying the material ofseveral kinds of vegetables daily consumption in local area, adopt the way of top dressing-sprayileaf, the trial of different levels of selenium fertilization was carried out .【 Results】 The selenium al vegetables spraying selenium fertilizer has improved in diferent levels compared witli control group, the ratio improvement are between 8 to 32 times;spray twice of “ Kang Xibao” 30 spray once of the “ organic selenium element” 200 g/60 kg can produce selenium-rich vegetables with obvious effect.【 Conclusion 】 Adding exogenous selenium fertilizer “ Kang Xibao” or “ organic selenium element” can effectively improve the quality, organic selenium content of vegetables, producrich vegetables.
