The leaf surface control agent comprises one or more of 2.5 mmol/L tetraethoxysilane, 2.5 mmol/L sodium silicate, 0.1 wt% to 0.3 wt% monopotassium phosphate, 100 mumol/L to 400 mumol/L zinc sulfate and 100 mumol/L to 200 mumol/L ferric sulfate and further comprises 0.1 wt% to 0.2 wt% glycine, 0.1 wt% to 0.2 wt% alanine and 0.5 wt% EM fungicide. By the adoption of the leaf surface control agent, Cadmium is effectively prevented from being absorbed and transferred to the edible portions of the vegetables, the damage to growth of the vegetables of Cadmium is reduced, the yield of the vegetables is greatly increased, and the quality of the vegetables is greatly improved.
Description
Technical field
The present invention relates to the foliar nutrient of vegetables, particularly control the foliar nutrient of cadmium pollution.
Background technology
Cadmium (Cadmium, Cd) extensively exists at nature, is a kind of heave metals trace elements.In Cd, Hg, As, Cr, Pb five heavy metal species pollutents, Cd is listed in first place, and in the dangerous chemicals of 12 kinds of global meanings of tool that propose in United Nations Environment Programme (UNEP), Cd is listed in first place.Cd in soil is mainly derived from the mankind's activity, and the waste water,waste gas and industrial residue being produced as mining, smelting, plating and basic chemical industry industry, containing using of chemical fertilizer, agricultural chemicals and the agricultural mud of Cd.In the vegetable soil of suburb, vegetables Cd contamination phenomenon all exists in China big and medium-sized cities, and trend is on the rise.China is subject to nearly 2,000 ten thousand hm of cultivated area of the heavy metal contaminations such as Cd at present
2, account for 1/5 of total area under cultivation.The increase of Cd content in soil, has a strong impact on production and the edible safety of farm crop.Vegetables are class crops of easy enrichment Cd.Luo Xiaomei etc. (2003) show the analysis and research of heavy metal element in the edible portion of 152 samples of 9 of In Chengdu kinds of vegetables, in the vegetable sample detecting, the exceeding standard rate of cadmium is that regulation Cadmium in Vegetables the highest Permissible limit standard in 29.4%(standard GB/T l5201-94 is 0.05 mg/kg).Ding Aifang etc. (2003) measure the green vegetables of planting on the scattered vegetable field soil of In The Suburbs of Nanjing, and detected result shows that the variation range of cadmium content in leaf is 0.39 ~ 0.73 mg/kg, and cadmium content all exceedes national food hygienic standard.Cd has become the Main Heavy Metal of China vegetables at present, is also one of principal element of restriction China's vegetables quality and Development of Non-polluted Vegetables product simultaneously.The long-term edible high vegetables of Cd that contain, can have a strong impact on HUMAN HEALTH by food chain, even cause canceration.
The improvement of Cd Pollution in Soil comprises engineering method, phytoremediation and agronomy regulation method etc.Engineering method is cost costliness not only, also can spoiled soil structure and soil microorganisms environment, also easily initiation " secondary pollution ".Heavy metal-polluted soil phytoremediation and agronomy regulation technology have obtained in recent years investigator and have paid attention to especially.But most heavy metal super-enriched plants that nature is found have certain limitation in practice, as long in growth cycle, biomass is few, plant is short and small, thus limit the development of plant soil restoration heavy metal contamination.And utilize competitive positively charged ion and Cd
2+the agronomy regulation technology of antagonistic effect, have and check the absorption of Cd and be transported to vegetables edible part, reduce vegetables edible part Cd content, improve effect of quality of vegetable.This technology is because production technique is simple, and raw material sources are extensive, easy to use, and the effect that reduces Cd content in vegetables edible part is remarkable, and prospect is widely used.
Summary of the invention
the object of the present invention is to provide a kind of vegetables heavy metal Cd content that reduces, promote vegetable growth, strengthen the blade face control agent of vegetable disease-resistant, drought resisting, the ability such as cold-resistant.This invention utilizes competitive positively charged ion (Zn, Fe, Si) and Cd
2+antagonistic effect and the adsorption precipitation effect of phosphoric acid salt to Cd, there is the murder by poisoning of the heavy metal Cd of reduction to vegetable growth, improve vegetable crop, check the absorption of Cd and transport in vegetables edible part, improve effect of quality of agricultural product.Be particularly useful for leaf vegetables and melon-fruit-like vegetable.
The object of the invention is to realize by following measures:
The blade face control agent that vegetables heavy metal Cd is polluted, comprises 2.5 mmolL
