Description
Technical field
The invention belongs to pesticide production technology field, be specifically related to a kind of method of utilizing natural pond liquid to prepare agricultural chemicals.
Background technology
At present, agricultural chemicals is that one has bioactive chemical substance, and wherein most of kind has certain toxicity to people and animals.Under normal circumstances, people wait the harm of harmful organism for insect pests grass, and the applications of pesticide have been arrived in the middle of physical environment, although reached the object of wanting, have also brought pollution problem simultaneously.If environment and Pesticide Residues amount exceed standard, can cause detrimentally affect to the mankind, other biological body and even the whole ecosystem.
After agricultural chemicals enters natural ecological environment, can enter human body by approach such as respiratory tract, digestive tube, skins.If reagent toxicity is larger, just likely causes and acute poisoning or subacute poisoning even cause life danger.Although some medicament acute toxicities are little, if stable in properties is difficult for after using decomposing, disappearing, will remain in water, atmosphere, farm crop, agricultural-food or fishery products, livestock product, finally enter human body, cause chronic poisoning.Meanwhile, pesticidal contamination also can cause the poisoning even dead of other biological, to such an extent as to destroys the eubiosis, therefore must control the residual of agricultural chemicals and pollute, to reduce impact and the harm on human society.
Summary of the invention
The object of the invention is to for the deficiencies in the prior art, a kind of method of utilizing natural pond liquid to prepare agricultural chemicals is provided, the method technique is simple, and energy consumption is little, and the agricultural chemicals of preparing to people and animals, farm crop, ecotope without any polluting and harm.
To achieve these goals, the technical solution used in the present invention is as follows:
Utilize natural pond liquid to prepare a method for agricultural chemicals, comprise the following steps:
(1) caustic soda of 0.3～0.5% natural pond liquid weight is added in the liquid of natural pond to sealed fermenting 1 year;
(2) impurity screening obtains filtered liquid;
(3) spices of interpolation 0.6～1.0% filtered liquid weight;
(4) filter after stirring and obtain mixed solution;
(5) add successively after the dispersion agent and 0.5～0.6% solidifying agent of mixed solution weight 0.4～0.5%, mix and make finished product.
Further, described dispersion agent is Macrogol 200; Described solidifying agent is polyacrylamide.
Again further, described step (1) is fermented in the liquid pool of natural pond, and step (2) is at filter vat inner filtration, and step (3), step (4) and step (5) all complete in receiver.
Further, described finished product effective K content is that 908mg/kg, available phosphorus contents are that 20.6mg/kg, total nitrogen content are that 18mg/kg, quick-acting copper content are that 0.206mg/kg, quick-acting iron level are that 0.025mg/kg, quick-acting manganese content are that 0.404mg/kg, quick-acting zinc content are that 0.207mg/kg, organic content account for 0.082%, and pH value is 7.87.
Preferred as one, described natural pond liquid pool is to adopt hollow brick and fine sand to be built into the cylindrical well pond of high 25m, radius 20m; Described filter vat is to adopt hollow brick and fine sand to be built into the square groove of long 20m, wide 3m, high 2.5m, in filter vat, on the limit of long 10m, is provided with filtering net and this filtering net is from coarse to fine is arranged in order every 2m place; Described receiver is to adopt hollow brick and fine sand to be built into the cylindrical tank of high 3m, radius 2.5m.
Mechanism of the present invention is: under anaerobic environment, natural pond liquid fermented material redox potential is lower, and reducing substances is more, after contacting, has physiology to take the effect of oxygen and degrease by force with insect.Secondly, owing to containing NH in the liquid of natural pond
4 +-N, NH
4 +-N has inhibition pathogen growth, poisons polypide intestines parietal cell, causes body function disorder, plays disease-resistant, insect-prevention effect.After being sprayed onto on plant leaf surface, a part of NH
4 +-N is absorbed by plant, takes food the NH being absorbed by plant when crop pests rests on plant surface
4 +-N can enter in polypide, dissolves and is absorbed intoxicating position by intestines parietal cell, thereby cause that insect is poisoned to death in intestinal juice.Another part NH in the liquid of natural pond
4 +-N rests on plant surface.Due to NH
4 +the molten boiling point of-N is lower, has part NH
4 +-N evaporates into gas after being sprayed to plant surface, in respiratory system enters the body of insect, causes insect death.
The present invention compared with prior art, has the following advantages and beneficial effect:
(1) agricultural chemicals that prepared by the present invention, not only contain the trace elements such as the macronutrients such as potassium, phosphorus, nitrogen and the copper that crop growth is played an important role, iron, manganese, zinc, also contain abundant amino acid (as Isoleucine, phenylalanine, α-amino-isovaleric acid etc.), and growth hormone, VITAMIN, Nucleotide etc., be conducive to the growth of plant.
(2) agricultural chemicals that prepared by the present invention, raw material is mainly people, animal class ight soil, the resistates of the organism such as plant residue after anaerobically fermenting, cost is very low; The people, animal class that the preparation of this agricultural chemicals not only can be processed contaminate environment just, plant residue etc., and the agricultural chemicals of preparing is safe and efficient non-harmful biological pesticide, this is that the chemical agent of killing disease and pest and the synthetic medicament on existing market, sold can not be compared.
(3) agricultural chemicals that prepared by the present invention does not add any hormone, nontoxic, harmless, pollution-free, has cold-resistant, the drought resisting of the farm crop of enhancing, the anti-several functions such as saline and alkaline, pest-resistant.
(4) natural pond of the present invention liquid raw material filters and separates etc. through multi-level, whole production process is all to carry out under normal temperature state by the method for physics, filtering objectionable constituent in the liquid of natural pond make the effective ingredient of natural pond liquid obtain abundant reservation and any variation does not occur, and in preparation process, add spices, effectively remove the peculiar smell in the liquid of natural pond, so make prepared agricultural chemicals quality obtain greatly improving.
(5) agricultural chemicals that the present invention prepares is nontoxic to people and animals, to the not broken ring of the Nature, free from environmental pollution, can be widely used in sterilization, the desinsection of various farm crop, fruit tree, vegetables and flowers and remove the evil, can replace chemistry, the chemical industry synthetic pesticide of domestic current use.
(6) raw material sources of the present invention are extensive, and manufacture craft is simple, and energy consumption is little, and preparation cost is cheap.
