A kind of novel green chemical fertilizer
Technical field
The present invention relates to a kind of vegetable fertilizer, especially a kind of a kind of novel green chemical fertilizer that sprays on farm crop, fruits and vegetables, cash crop blade face.
Background technology
Fertilizer provides the necessary nutritive element of plant-growth, improves soil regime, improves the important substance of crop yield.Since the fifties, also increasing to the demand of farm crop along with the continuous growth of population, only depend on traditional organic fertilizer to be difficult to keep the demand of soil, chemical fertilizer more and more comes into operation.According to statistics, from the fifties to the nineties, the usage quantity of whole world chemical fertilizer has increased about ten times, and grain yield has increased about three times.Take China as example, China is large agricultural country, and to account for the arable land in the world 7%, the keeping amount accounts for the population in the world 22%, and this has the effect of giving the credit to greatly chemical fertilizer.
Since the fifties, also increasing to the demand of farm crop along with the continuous growth of population, only depend on traditional organic fertilizer to be difficult to keep the demand of soil, chemical fertilizer more and more comes into operation.Chemical fertilizer refers to take mineral, air, water as raw material the fertilizer be processed into through chemistry or mechanical method, and it is to grow up on the basis of Natural fertilizers.The result of tool Food and Argriculture OrganizationFAO investigation shows that the average effect of increasing production of chemical fertilizer is 40--60%, and China recent years shows that to the monitoring result of soil fertility chemical fertilizer is to the contribution rate whole nation average out to 57.8% of agricultural-food.
Compare with traditional organic fertilizer, the characteristics such as chemical fertilizer has component content high, and is soluble in water, easily utilized by plant absorbing, and effect is rapid, reasonably using for the fertility that improves soil, the output that increases the farm crop unit surface has important effect.Development along with scientific-technical progress and chemical industry, the kind of chemical fertilizer, kind is more and more, common every kind of chemical fertilizer has it to use specific aim, time of application, method, dosage is also different. how correctly to select applicable chemical fertilizer, the accurate proportioning of how to carry out various fertilizer often becomes puzzlement user's subject matter, some chemical fertilizer is difficult to produce a desired effect because concentration is low when using, some chemical fertilizer then is owing to using excessive counter its evil that is subjected to of farm crop that makes, some chemical fertilizer causes nutriment unbalance owing to proportioning is unreasonable when using, also some chemical fertilizer can make soil be polluted, food, toxic ingredient increases in feed and the tap water, also can pollute environment, based on the problems referred to above, it is wide that users urgently wish to produce sphere of action, the novel green chemical fertilizer of environmental contamination reduction.
Summary of the invention
The object of the invention is to overcome the weak point of currently available products, and a kind of novel green chemical fertilizer is provided.
Technical scheme of the present invention is: the present invention is by being comprised of rhenium, compost, biomass ferment residue, tellurium mixing.
The mass content of described vegetable fertilizer is: rhenium 3.2%-14.8%, compost 4.3%-20%, biomass ferment residue 65-75%, tellurium 1.3%-1.8%.
Described compost is a kind of in the stalk stem of crop and the people and animals' fecaluria.
Described biomass ferment residue is a kind of in stalk and the vinasse.
Preparation method of the present invention is:
(1), the biomass of vinasse, stalk are regulated pH is 8.5~9.0, current potential for-185mv~-the 210mv condition carries out anaerobically fermenting, carries out sterilising treatment after the fermentation, obtains the biomass ferment residue;
(2), 1: 2~1: 3 mud of biological residue mass ratio is mixed static 1~2 day;
(3), in the middle of said mixture, add rare elements and trace element, can obtain Green Chemistry fertilizer.
The invention has the advantages that: (1) not only can the residual murder by poisoning of decomposing pesticide, and generation and the development that can alleviate disease and pest; (2) foliage-spray has not only been protected soil, and has greatly increased the absorption of plant leaf surface to nutrient, has promoted photosynthesis, has promoted plant growth, has shortened growth cycle; (3) adopt the present invention can produce the series product of different components and label, can use according to the gradation of crop different growing stages; (4), effectively reduce and make nitrate content in the object, nontoxic without hormone, nuisanceless; (5), effectively strengthen plant cold resistance, Freezing hardiness; (6), manufacture method is scientific and reasonable, technique is simple, easy handling.
Embodiment
Example 1:
(1), the biomass of vinasse, stalk are regulated pH is 8.5, current potential carries out anaerobically fermenting for-185mv condition, carries out sterilising treatment after the fermentation, obtains the biomass ferment residue;
(2), mix static 1 day producing 1: 2 mud of thing residue mass ratio;
(3), in the middle of said mixture, add rhenium and tellurium, can obtain Green Chemistry fertilizer.
Example 2:
(1), the biomass of vinasse, stalk are regulated pH is 8.8, current potential carries out anaerobically fermenting for-200mv condition, carries out sterilising treatment after the fermentation, obtains the biomass ferment residue;
(2), 1: 2.5 mud of biological residue mass ratio is mixed static 1.5 days;
(3), in the middle of said mixture, add rhenium and tellurium, can obtain Green Chemistry fertilizer.
Example 3:
(1), the biomass of vinasse, stalk are regulated pH is 9.0, current potential carries out anaerobically fermenting for-210mv condition, carries out sterilising treatment after the fermentation, obtains the biomass ferment residue;
(2), 1: 3 mud of biological residue mass ratio is mixed static 2 days;
(3), in the middle of said mixture, add rhenium and tellurium, can obtain Green Chemistry fertilizer.
