Technical field
The present invention relates to a kind of fertilizer manufacture method, particularly relate to a kind of method of producing liquid zinc fertilizer.
Background technology
As everyone knows, fertilizer is the indispensable nutrient of agriculture production and plant absorbing, and plant need absorb various nutrients, needs to absorb nutrition such as protein, fat, trace element just as the people.Wherein, zinc fertilizer is exactly one of nutrient of plant needs.Zinc fertilizer in the market mainly is Zinc Sulphate Heptahydrate and a small amount of Zinc Sulphate Monohydrate, is solid, its solvability and unsatisfactory by the plant absorbing ability, and peasant Hua Liaoqian, it is little to produce effects, and adds that the zinc fertilizer of poor quality on the market is full of, and the phenomenon of cheating the farmers is of common occurrence.In addition, in state-owned soil more than 95% lack soluble Zn, how to develop best zinc fertilizer as soon as possible, the service agriculture, rural areas and farmers, build a harmonious society, must develop suitable best zinc fertilizer as soon as possible, this be we be engaged in agriculture the fertilizer research worker responsibility with the obligation.
Summary of the invention
The purpose of this invention is to provide a kind of technological specification, the method for producing liquid zinc fertilizer easy and simple to handle, free of contamination.
In order to achieve the above object, technical scheme of the present invention is achieved in that the method for producing liquid zinc fertilizer, it is solvent with water, dehydrated alcohol is an auxiliary agent, and zinc sulfate is solution, extracts by weight percentage, wherein water is 69.86%, dehydrated alcohol is 0.14%, zinc sulfate is 30%, and its total amount is 100%, and unit is gram; Aforementioned water, dehydrated alcohol, zinc sulfate are inserted in the reactor together, are that continuously stirring 3 to 4 hours leaves standstill the normal temperature state that is cooled under 30 ° to 70 ℃ the condition in temperature, take out in the reactor and are stirred material, are the liquid fertilizer of producing.
The method of producing liquid zinc fertilizer involved in the present invention is characterized in that, temperature is 50 ℃, and churning time is 3.5 hours.
The method of producing liquid zinc fertilizer that the present invention is alleged has technological specification, easy and simple to handle, non-environmental-pollution, is suitable for advantage such as modern industrialization batch process; The liquid zinc fertilizer that utilizes the present invention to produce, cheap, easy to use, need not the soil conversion energy and directly absorbed by plant, be used for the demand of plant to zinc, control plant zinc deficiency disease is played and shortly grow, takes root, fertile leaf, is good for the effect that stem, strong sprout, diseases prevention are degeneration-resistant, raise productivity and improve the quality.The alleged zinc fertilizer of the present invention is a liquid, is little yellow, and substantially tasteless can be widely used in fields such as agricultural, forestry, can convert water in 1: 200 ratio and be used for plant leaf surface and spray, and also can be used for seed dressing and drip irrigation.Produce liquid zinc fertilizer with the present invention, its every technical indicator all reaches or is better than specialized standard, and for example the accurate value of the content of zinc (Zn) is g/L 〉=100, and liquid zinc fertilizer zinc content of the present invention is more than 130; Harmful element arsenic (As), cadmium (Cd), chromium (Cr), plumbous (Pb) (all in element) percentage composition are far below the technological standard value.
Embodiment
Technical solution of the present invention is described in detail as follows in conjunction with the embodiments: water intaking (water quality should reach drinking water standard) is 69.86% respectively by weight percentage, and dehydrated alcohol is 0.14%, and zinc sulfate is 30%, and its total amount is 100%, and unit is gram; With total amount is 10 kilograms of (10,000 gram) preparations, 6986 grams of then fetching water, dehydrated alcohol 14 grams, zinc sulfate 3000 grams; Aforesaid water, dehydrated alcohol and zinc sulfate are inserted in the reactor together, are that continuously stirring left standstill the normal temperature state that is cooled to after 3.5 hours under 50 ℃ the condition in temperature, take out in the reactor and are stirred material, are the liquid zinc fertilizer of producing.If want practical application, can be by liquid zinc fertilizer: water=convert water preparation at 1: 200, can be directly used in plant leaf surface and spray, also can be used for seed dressing and drip irrigation.
