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.At Cd, Hg, As, Cr, Pb five in heavy metal species pollutent, Cd is listed in first place, and in the dangerous chemicals of the 12 kinds of global meanings of tool proposed in United Nations Environment Programme (UNEP), Cd is listed in first place.Cd in soil is mainly derived from the activity of the mankind, as mining, smelt, plating and basic chemical industry industry the waste water,waste gas and industrial residue that produces, containing using of the chemical fertilizer of Cd, agricultural chemicals and agricultural sludge.In the vegetable soil of suburb, vegetables Cd contamination phenomenon all exists in China big and medium-sized cities, and be on the rise trend.Current China is by nearly 2,000 ten thousand hm of cultivated area of the heavy metal contaminations such as Cd
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 9 of In Chengdu kinds of vegetables 152 samples, in the vegetable sample detected, the exceeding standard rate of cadmium is the 29.4%(standard GB/T l5201-94 the highest Permissible limit standard of regulation Cadmium in Vegetables is 0.05mg/kg).Ding Aifang etc. (2003) measure the green vegetables that the scattered vegetable field soil of In The Suburbs of Nanjing is planted, and detected result shows that the variation range of cadmium content in leaf is 0.39 ~ 0.73mg/kg, and cadmium content all exceedes national food hygienic standard.Current Cd has become the Main Heavy Metal of China vegetables, is also one of principal element of restriction China's vegetables quality and Development of Non-polluted Vegetables product simultaneously.The long-term edible vegetables high containing Cd, 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 intensive 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 obtain investigator in recent years and pay attention to especially.But most heavy metal super-enriched plants that nature finds 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, there is the absorption of checking Cd and be transported to vegetables edible part, reducing vegetables edible part Cd content, improve effect of quality of vegetable.This technology due to production technique simple, raw material sources are extensive, easy to use, and the effect reducing Cd content in vegetables edible part is remarkable, and be widely used prospect.
Summary of the invention
The object of the present invention is to provide and a kind of reduce vegetables heavy metal Cd content, 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 phosphoric acid salt to the adsorption precipitation effect of Cd, have and reduce heavy metal Cd to the murder by poisoning of 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 be realized by following measures:
The blade face control agent that vegetables heavy metal Cd is polluted, comprises 2.5mmolL
