Abstract
The present invention relates to a method for enhancing bacterial activity of bio-fertilizer by using nuclear radiation technology, which is characterized in that Co60 rays are used as the radiation source so as to radiate a mixed liquor made of bio-fertilizer bacteria of azotobacteria, phosphorus bacteria and potassium bacteria. The dose rate of the radiation source is 10 to 40 (10<-2>GY/S), the total dose of the radiation source is 0.5 to 3.0 (10<2>GY), the radiation time of the radiation source is 5 to 8 (10<2> seconds), and the radiation distance of the radiation source is 1 to 1.5M. The present invention can reduce variation speed of the bacteria and enhance activity of nitrogenase so as to obviously enhance the quality of the bio-fertilizer.
Description
The invention belongs to a kind of method that improves bacterial activity of bio-fertilizer with nuclear radiation tech.
Bio-feritlizer utilizes the reciprocal alternate effect of beneficial microorganism and crop, can increase the content that soil absorbs nitrogen, improves Soil structure, keeps soil from packing together, and the growth of stimulating plant cell promotes various plant establishments, germination, premature ripening.But existing be used to inoculate the bacterial classification of making bio-feritlizer and be easy to morph, cause the activity of nitrogenase to reduce, and reduce the quality of bio-feritlizer.Therefore all need to upgrade every year with first class inoculum, do like this take a lot of work, time-consuming, deficiency in economic performance.Still lack the slow bacterial classification speed of mutation in a kind of court of a feudal ruler at present, improve active method.
The invention provides the method that a kind of nuclear radiation tech improves bacterial activity of bio-fertilizer, the slow biological fertilizer strain speed of mutation in the court of a feudal ruler improves bacterial activity easily, guarantees the quality of bio-feritlizer, increases economic efficiency.
Technical scheme of the present invention is:
Method with nuclear radiation tech raising bacterial activity of bio-fertilizer is characterized in that: as source of radiation, irradiation contains the biological fertilizer strain of vinelandii with the Co60 ray.
The dose rate of described source of radiation is 10～40 (10
-2GY/S).
The total dose of described source of radiation is 0.5～3.0 (10
2GY).
The radiated time of described source of radiation is 5～8 (10
2Second).
Described source of radiation is 1～1.5 meter to the irradiation distance of bacterial classification.
Described biological fertilizer strain is the mixed solution that vinelandii, phosphorus bacteria and potassium bacterium are made, wherein vinelandii: phosphorus bacteria: the potassium bacterium is 1～3: 5～8: 3～5.
The bacterial classification that uses the present invention to handle is inoculated the making bio-feritlizer, and the slow biological fertilizer strain speed of mutation in the court of a feudal ruler makes nitrogenase activity improve about 50% easily, measured through 5 years, bacterial strain behind the irradiation is active lasting, does not fall trend as follows, has guaranteed the quality of bio-feritlizer effectively.Bacterial activity comparison test result behind former bacterial classification and the application the inventive method irradiation is as follows:
| The irradiation bacterium numbering | Radiation dose rate 10 -2GY/S | Irradiation time 10 2S | Irradiation total dose 10 2GY | Bacterial activity molc 2h 4/ h. pipe |
| Former bacterial classification--irradiation bacterial classification 1-3A irradiation bacterial classification 1-3A irradiation bacterial classification 4-1D2 irradiation bacterial classification 4-1D2 irradiation bacterial classification 4-1D2 irradiation bacterial classification 4-1D2 irradiation bacterial classification 4-1D2 irradiation bacterial classification 4-1D2 | -- 39.60 39.60 11.64 11.64 11.64 11.64 11.64 11.64 | -- 7.08 7.08 5.40 5.40 5.40 5.40 5.40 5.40 | -- 2.804 2.804 0.629 0.629 0.629 0.629 0.629 0.629 | 1.185 1.815 1.960 2.070 1.845 1.440 1.875 1.845 1.965 |
Embodiments of the invention below are described in detail in detail:
With biological fertilizer strain vinelandii, phosphorus bacteria and potassium bacterium by proportioning 1～3: make mixed solution at 5～8: 3～5, puts into radiation field, uses Co
60Ray carries out irradiation as source of radiation, and the dose rate of used source of radiation is 10～40 (10
-2GY/S), the total dose of source of radiation is 0.5～3.0 (10
2GY), the radiated time of source of radiation is 5～8 (10
2Second), source of radiation is 1～1.5 meter to the irradiation distance of bacterial classification, makes bacterial classification absorb energy equably; Then the bacterial classification mixed solution is adsorbed on and forms the solid dry powder formulations on the organic fertilizer resource carriers such as furfural dregs, turfy soil, lime carbonate, calcium sulfate, add by any one fertilizer synergistic agent among urea, bicarbonate of ammonia, ammonium sulfate, Secondary ammonium phosphate, primary ammonium phosphate, calcium superphosphate, the potassium primary phosphate; Also can add additives such as rare earth, boric acid, Sodium Tetraborate, Sodium orthomolybdate, ammonium molybdate according to the characteristics of specific soil, through pulverize granulation, oven dry, bio-feritlizer, packing is dispatched from the factory at last.
