Abstract
The present invention relates to a method for preparing leaf fertilizer for reducing residual pesticide and promoting plant growth. The method comprises the following steps that firstly, after monosaccharide, sugar alcohol and sugar derivatives or oligosaccharide and other saccharide are dissolved in water, and rare earth nitrate for agriculture use or rare earth previously dissolved by dilute acid is added to the solution, wherein the adding amount of the rare earth accounts for 0.4% to 30.8% of the saccharide; then, a reaction is carried out to a mixed solution of the saccharide and the rare earth for twenty-four hours at a temperature of 10 DEG C to 40 DEG C, a pH value of the reaction liquid is regulated to 4 to 7 so as to obtain liquid leaf fertilizer, and the liquid leaf fertilizer is further dried so as to obtain the solid leaf fertilizer, wherein the saccharide can be one kind of or a mixture of several kinds of monosaccharide, sugar alcohol and sugar derivatives or oligosaccharide, the content of the saccharide is controlled between 250g and 650g per mu, and the total rare earth content is controlled between 1g and 25g per mu. The degradation rate of organic phosphorus pesticide is more than 80% after the leaf fertilizer of the present invention is sprayed for several days, and a crop yield increase rate ranges from 3 to 20%. The present invention has the advantages of simple production process, easy acquirement of raw material, less investment, no pollution and requirement satisfaction for producing green food.
Description
Technical field
The present invention relates to the foliage fertilizer preparation method of the short plant growth of a kind of decreasing organic phosphorous pesticide residue.
Background technology
China has a large population in a small area, and how to guarantee that food quantity safety and quality safety are long-term and difficult task.With regard to plant-sourced food, no matter be large grain-production, or the production of vegetable and fruit, their growth busy season is also mostly to be that the busy season takes place in insect pest.Present stage, the peasant also needed to use the chemical pesticide control insect pest in order to improve their output and quality.Along with the complete prohibition use and the pyrethroid pesticide of organochlorine pesticide easily makes insect develop immunity to drugs, organophosphorus pesticide has accounted for 70% of sterilant total amount at present.Long-term scale operation and use organophosphorus pesticide not only causes severe contamination to environment, residual in food and feed people and cultivated animals is also seriously influenced.And carry out research, the pollution-free food production base of transgenic pest-resistant, disease-resistant crop construction, biological pesticide and organophosphorus pesticide development of substitutes, set up the superseded use of Food Quality and Safety security system, food quality and safety (QS) market access mechanism and some organophosphorus pesticide or in food hygienic standard, reach not have to detect and all to need to require etc. very strong science and technology and funds support, apply from developing to as a kind of agricultural chemicals, need multi-disciplinary cooperations such as chemistry, agronomy, medical science and environment, go through more than ten years.According to the national conditions of China, present stage is the use of impossible total ban organophosphorus pesticide also.Therefore, can degrade and make organophosphorus pesticide in the object, the foliage fertilizer that can promote plant growth again is current and presses for from now on.
The foliage fertilizer of China's development at present is more, and its main purpose is to promote plant growth and improve quality.As a kind of solubility compound powder (ZL98103155.2) and a kind of efficient many bacterium energy foliage fertilizers and preparation method thereof patented products such as (ZL92109659.3) as fertile medicine, and existing promotion plant growth has the product for agriculture of decreasing organic phosphorous agricultural chemicals to have not yet to see patent report.
Summary of the invention
The a large amount of uses that The present invention be directed to present organophosphorus pesticide are developed a kind of organophosphorus pesticide degraded in the object that can promote to do to the present situation that food pollutes, and can improve the foliage fertilizer of crop yield again.
Preparation method of the present invention or technology: carbohydrate or sugar derivatives earlier with after the water dissolution, are added rare earth element, and re-adjustment reacting liquid pH value to 4～7 are filtered the back and are concentrated and just obtains liquid foliage fertilizer, further are drying to obtain solid-state foliage fertilizer.Carbohydrate wherein is monose, sugar alcohol and sugar derivatives or oligose, or appoint wherein a kind of, the also mixture that they can be formed in any ratio; Wherein rare earth element is agricultural rare earth nitrate, or uses diluted acid dissolved rare earth in advance.No matter be liquid foliage fertilizer or solid-state foliage fertilizer, every mu of contents of saccharide is controlled at 250g～650g in use; The rare earth element overall control is at 1g～25g.
Therefore, essence of the present invention is to utilize carbohydrate to be part and rare earth element ligand complex, the malt sugar of preparing soil mixture.Use this mixture on the crop that has sprayed organophosphorus pesticide organophosphorus pesticide degradation rate in a couple of days is reached more than 80%, the crop yield rate is 3～20%, and the crop yield probability is about 85%.And production technique of the present invention is simple, and raw material is easy to get, and less investment is pollution-free, meets the needs and the requirement of current and pollution-free food production from now on.
