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.
Description
Technical field
The present invention relates to grow tobacco a heavy metal degraded and use foliage fertilizer.
Background technology
Heavy metal is meant that density is greater than 4 (g/cm
3) metal, exist with compound form in that occurring in nature is many, along with exploitation, smelting, processing and commercial make of the mankind, make many heavy metals as in entering atmosphere, water body or the soil such as lead, cadmium, mercury to heavy metal, cause serious heavy metal contamination.Tobacco is a kind of special tobacco product, and the various metallic elements (comprising heavy metal element) that in the back tobacco of self burning, contain can get into human body with main flume, and the excessive heavy metal that contains in the tobacco can direct influence the health of human body.Main sources of heavy metal is the soil in its growing environment in the tobacco; The tobacco long term growth is in the heavy metal soil of high density; Its normal growth can receive the influence of heavy metal, and heavy metal can obtain enrichment in tobacco, makes tobacco itself become source of heavy metal pollution.
Heavy metal contamination is different with other pollution, and heavy metal itself is difficult to be degraded, and be difficult to from soil, remove fully, so the difficulty of governance of heavy metal pollution of soil is bigger.The measure that solves tobacco heavy metal contamination at present mainly is the processing to the soil that receives heavy metal contamination; For example adopt the Agro-ecological Engineering measure; Receiving special plant and the mikrobe of breeding on the soil of heavy metal contamination; Through these special plants and mikrobe siphons away or the soil of degrading in heavy metal, thereby reach the purpose that purifies soil, but this method treatment time long, take effect slow; Can let the soil of handling can't carry out the plantation of tobacco in a long time, the utility value of soil is affected.Someone proposes to adopt physics, physical and chemical principle to administer heavy-metal contaminated soil; Like isolation method, washing out method, thermal treatment, electrochemical process etc.; Solution heavy metal pollution of soil problem that can be quick, thorough, stable; But the disposable input of this method is high, and does not have investment repayment, is difficult in the daily operation and applies.
Summary of the invention
The purpose of this invention is to provide a kind of foliage fertilizer, lower the content of heavy metal in tobacco, reduce the influence of heavy metal, improve the quality of tobacco tobacco to heavy metal degraded in the tobacco.
In order to realize above purpose, the technical scheme that the present invention adopted is: foliage fertilizer is used in grow tobacco a heavy metal degraded, is to be mixed by following components in weight percentage: xanthohumic acid 30-50%; Phosphate fertilizer 5-10%, potash fertilizer 10-15%, trace element fertilizer 6-18%; Seaweeds 2-5%, surplus is a water.
Said trace element fertilizer comprises manganese fertilizer, zinc fertilizer, copper fertilizer, fertiliser containing magnesium, iron fertilizer, molydbenum fertilizer, and it accounts for the 1-3% of foliage fertilizer gross weight respectively.
Tobacco heavy metal of the present invention degraded is to be pulverized by each component to be mixed and made into foliage fertilizer, and dilution is 500 times during use, at the nursery stage of tobacco, a phase--the ripening stage is taked foliage-spray in group, avoids spraying with Louing and respraying with once in 10-15 days.
Foliage fertilizer is used in tobacco heavy metal degraded of the present invention; Strengthen the consumption of necessary trace element of tobacco growing and phosphorus potassium, under the effect of xanthohumic acid and seaweeds, strengthen the activity of necessary trace element and phosphorus potassium; Utilize activity that tobacco must growth elements to be better than the principle of heavy metal element simultaneously; Make the heavy metal in necessary trace element and the phosphorus potassium replacement tobacco, weaken the absorption of tobacco, play the effect that reduces tobacco heavy metal contamination heavy metal.
Foliage fertilizer is used in tobacco heavy metal degraded of the present invention; Wherein potash fertilizer, phosphate fertilizer can adopt the tobacco producer's routine to select; For example potash fertilizer can be selected Repone K, vitriolate of tartar, potassium magnesium salts or compound potassium nitrate fertilizer, potassium hydrogen phosphate composite fertilizer for use; Phosphate fertilizer can be selected fishbone powder, superphosphate of lime, fused(calcium magnesium)phosphate or potassium hydrogen phosphate composite fertilizer, ammonium hydrogen phosphate composite fertilizer etc. for use, carries out cubage as single phosphorus, potash fertilizer respectively when adopting composite fertilizer.Wherein trace element fertilizer can carry out the routine selection according to concrete tobacco varieties.
