一种烟草重金属降解用叶面肥

Leaf surface fertilizer for degrading tobacco heavy metal

Abstract

The invention discloses a leaf surface fertilizer for degrading tobacco heavy metal. The leaf surface fertilizer for degrading tobacco heavy metal is prepared by mixing the following components by weight percent: 30-50 percent of fulvic acid, 5-10 percent of phosphate fertilizer, 10-15 percent of potassic fertilizer, 6-18 percent of trace element fertilizer, 2-5 percent of cytex and the balance of water. According to the leaf surface fertilizer for degrading tobacco heavy metal, the use level of the trace elements necessary for tobacco growth as well as phosphorus and potassium is increased, and the activity of the necessary trace elements as well as phosphorus and potassium is strengthened under the action of the fulvic acid and the cytex; in addition, by utilizing the principle that the activity of the elements necessary for tobacco growth is stronger than that of heavy metal elements, heavy metal in the tobacco is replaced by the necessary trace elements as well as phosphorus and potassium, therefore, the absorption of heavy metal by the tobacco is weakened, and the function of reducing heavy metal pollution of the tobacco is achieved.
本发明公开了一种烟草重金属降解用叶面肥,是由以下重量百分比的组分混合而成:黄腐酸30-50%,磷肥5-10%,钾肥10-15%,微量元素肥6-18%,海藻素2-5%,余量为水。本发明的烟草重金属降解用叶面肥,加大烟草生长必须微量元素及磷钾的用量,在黄腐酸和海藻素的作用下,强化必须微量元素和磷钾的活性,同时利用烟草必须生长元素的活性强于重金属元素的原理,使必须微量元素和磷钾替换烟草中的重金属,削弱烟草对重金属的吸收,起到降低烟草重金属污染的作用。
