Description
Technical field
The present invention relates to agricultural fertilizer technical field, particularly a kind of paddy rice is special falls cadmium biological organic fertilizer and preparation method thereof.
Background technology
Paddy rice is the staple food crop of China, and be engaged in peasant household that rice does to produce close to 50% of peasant household's sum, the whole nation has the population of more than 60% to take rice as staple food.Except edible, rice also has multiple use.At present, directly edible rice accounts for 84%, and industrial, feed is with accounting for 10%, and its output height and quality are directly connected to the life of whole national economy and people and healthy.
Cadmium is a kind of trace heavy metals to the toxic effect of animals and plants, extremely strong to human toxicity, very easily be absorbed by the body, cadmium has high movability and low poisoning concentration, long half time, by the microbiological deterioration in soil, very easily can not be absorbed by plants and accumulates, it pollutes for irreversible process, can affect the yield and quality of crop after exceeding certain limit.
In recent years, due to the unreasonable discharge of Industrial " three Waste ", solid waste (especially municipal wastes) process be not good at, sewage irrigation, agricultural sludge and the fertilizer etc. used containing heavy metal element, result in heavy metal in soil cadmium content sharply to increase, cause farmland cadmium Cd to pollute day by day serious.When in the soil of paddy growth in cadmium pollution, cadmium accumulates in a large number in its root, stem, leaf and seed, has a strong impact on growing and rice quality of paddy rice, healthy through food chain enrichment harm animals and humans.
In order to reduce the impact of cadmium on rice growth and yield and quality, exploitation one both for paddy rice to nitrogen (N), phosphorus (P
2o
5), potassium (K
2o) demand characteristics (demand percentage is 1:0.5:1.3) of nutrient carries out scientific formula, effectively can reduce again the special fertilizer of paddy rice to Cd uptake and seem very necessary.
Summary of the invention
The technical problem to be solved in the present invention is: provide that a kind of specificity for paddy rice uptake characters is strong, fertilizer efficiency is high, can effectively stop paddy rice to Cd uptake, significantly improve that the paddy rice of yield and quality of rice is special falls cadmium biological organic fertilizer;
Another technical problem that the present invention will solve is: provide a kind of paddy rice the special preparation method falling cadmium biological organic fertilizer.
For solving the problems of the technologies described above, the technical solution used in the present invention is:
A kind of paddy rice is special falls cadmium biological organic fertilizer, is formed by the preparation of raw material of following weight part
Urea 1-3 diammonium phosphate 2-6
Potassium sulfate 1-3 trace element 0.5-1.5
Fowl and animal excrement 30-50 agricultural crop straw 20-40
Humic acids 10-30 biological bacteria 0.5-1.5
Described trace element is: the one in iron, manganese, zinc, silicon, two kinds, multiple or complete
Described fowl and animal excrement is: pig manure, cow dung or chicken manure;
Described agricultural crop straw is: straw, cigarette stalk or cornstalk;
Described biological bacteria is: the one in vinelandii, phosphate solubilizing bacteria, potassium solubilizing bacteria, genus bacillus, actinomycetes yeast, two kinds, multiple or whole.
Its preferred technical scheme one is formed by the preparation of raw material of following weight part:
Urea 2 diammonium phosphate 4
Potassium sulfate 2 trace element 1
Fowl and animal excrement 40 agricultural crop straw 20
Humic acids 30 biological bacteria 1
Its preferred technical scheme two is formed by the preparation of raw material of following weight part:
Urea 1 diammonium phosphate 6
Potassium sulfate 1 trace element 1.5
Fowl and animal excrement 30 agricultural crop straw 40
Humic acids 20 biological bacteria 0.5
Its preferred technical scheme three is formed by the preparation of raw material of following weight part:
Urea 3 diammonium phosphate 2
Potassium sulfate 3 trace element 0.5
Fowl and animal excrement 50 agricultural crop straw 30
Humic acids 10 biological bacteria 1.5
Prepare the special method of falling cadmium biological organic fertilizer of above-mentioned paddy rice, the steps include:
First, get urea, diammonium phosphate, potassium sulfate, trace element, fowl and animal excrement, agricultural crop straw, humic acids and biological bacteria by weight, for subsequent use respectively;
Secondly, by crops stalk crushing, mix with fowl and animal excrement for subsequent use, biological bacteria, humic acids, use fermentor tank quick fermentation to become thoroughly decomposed into the combination of biological organic functions amendment, for subsequent use;
3rd, urea for subsequent use, diammonium phosphate, potassium sulfate and trace element are mixed into inorganic nutrients optimization of C/C composites by proportioning fragmentation, for subsequent use;
4th, biological organic functions amendment combination for subsequent use and inorganic nutrients optimization of C/C composites are pulverized in proportion again, mix, the dry damping of high speed centrifugation, obtains compound, for subsequent use;
5th, compound is adopted the granulation of matrix composite technology multigraph press, through centrifugal drying, screening, obtain that paddy rice is special falls cadmium biological organic fertilizer.
The invention has the beneficial effects as follows:
A kind of paddy rice of the present invention is special falls cadmium biological organic fertilizer, adopts fowl and animal excrement, agricultural crop straw etc. organic as benchmark fertilizer, with the addition of inorganic fertilizer, trace element, humic acids and biological bacteria.Use that paddy rice of the present invention is special falls cadmium biological organic fertilizer, the specificity for paddy rice uptake characters is strong, fertilizer efficiency is high, and effectively can reduce the absorption of paddy rice to cadmium, rice yield can improve 5-10%, and the rice quality of production can reach green food requirement.
Cadmium principle falls in the present invention: main micro-fertilizer (iron, manganese, zinc, siliceous fertilizer) and the organic matter of using hinders cadmium.
1, cadmium principle falls in micro-fertilizer (iron, manganese, zinc, siliceous fertilizer): the absorption of crop to cadmium and the mineral element such as iron, zinc exists the common approach of part.When certain heavy metal content in soil is higher, comparatively serious to soil pollution time, can utilize another kind of to crop harm is comparatively light and concentration is low time to the favourable micro-antagonism of plant growth it.In research in the past, there is increasing evidence to show between cadmium and iron there is interaction, enriched iron fertilizer and significantly can reduce cadmium content in rice plant and rice and accumulation volume.The Cd accumulation that manganese effectively can control rice also early has report.Due to cadmium and zinc normally with and raw, be period element, have similar chemical property and geochemical behavior, thus zinc has the characteristic that antagonism cadmium is absorbed by plants.Silicon suppresses the toxic action of cadmium to be because silicon significantly can increase the adsorptive capacity of soil to cadmium, silicon can suppress cadmium to enter rice plant simultaneously, make it reduce in the distribution of rice root, blade, leaf sheath and accumulation, silicon suppresses cadmium to the murder by poisoning of rice plant Physiological and Biochemical Metabolism simultaneously.Therefore, cadmium pollution rice soil using micro-fertilizer (iron, zinc, manganese, siliceous fertilizer etc.), is one of effective measure reducing paddy rice cadmium poisoning and rice content.
2, cadmium principle falls in organic matter: in the soil of cadmium pollution, apply organic matter, can increase soil fertility on the one hand, and improvement soil property, can alleviate again the biological effectiveness of cadmium on the other hand preferably.Due to functional group a large amount of in organic matter existence and there is larger specific surface area, Cadmium in Soil ion and its formation cadmium organic complex can be promoted, increase soil to the adsorptive power of cadmium, improve soil to the resiliency of cadmium, thus minimizing paddy rice absorbs it, holds it back and enters food chain.Therefore, in cadmium pollution soil, apply organic matter is a kind of highly effective administering method.
