Crop nitrogenous fertilizer derives from chemical nitrogen fertilizer and biological nitrogen fixation, chemical nitrogen fertilizer is that tremendous contribution made by crop yield, but chemical nitrogen fertilizer production cost is high, utilization ratio is low, and constantly spoiled soil fertility and environmental ecology, one of obstacle becoming agricultural sustainable development.Biological nitrogen fixation is completely biological and microorganism is spontaneous carries out, and need not provide any energy and equipment, thus which reduce the consumption of the energy, non-pollutant discharge, be conducive to preserving the ecological environment.Meanwhile, owing to reducing and eliminating the input of chemical nitrogen, nitric acid and nitrous acid material in agricultural-food are significantly reduced, improves the quality of agricultural-food, reduce carcinogenic substance to the harm of the mankind.
Nitragin is the Main Bacteria fertilizer of plantation leguminous crop, because containing root nodule bacterium that are a large amount of, live body inside it, people claim it to be fertilizer of living.Nitragin came out in Europe early than 1896.Rihizobium japonicum is biological bacteria that is a kind of and soybean symbiosis, nitrogen supply soybean free in its fixed air, to meet the demand of soybean to nitrogen, is the good measure of soybean yield-increasing, joint fertilizer, decreasing pollution, is subject to the attention of researchist all over the world.Rihizobium japonicum is a kind of microbial preparation of work, the root nodule bacterium in root nodule and leguminous plants mutualism: the organism that leguminous plants is manufactured by photosynthesis, part supply root nodule bacterium; The ammonia that root nodule bacterium are manufactured by biological nitrogen fixation, then supply leguminous plants.The formation of soybean nodulation is that root nodule bacterium invade from root hair, are present in the parenchyma cell of root cortex because the root nodule bacterium in soil invade caused by root tissue.Root nodule bacterium are rapid fissiparity in tegumental cell, and the simultaneously stimulation that invades because of root nodule bacterium of tegumental cell, carry out cell fission, tegumental cell number increases, enlarged volume, and formation wart like structure is exactly root nodule.
Research shows, if do not have root nodule bacterium, will execute the nitrogenous fertilizer demand that 115 kilograms of urea could meet per mu yield 180 kilograms of soybean for every mu.Because soybean is satisfied the demand by the symbiotic nitrogen fixation of contained nitrogen and root nodule bacterium in absorption soil, fertilizer, so will note the relation handling both well when using chemical nitrogen fertilizer, if when fertilizer nitrogen amount of application is too much, root nodule number reduces, fixed nitrogen rate reduces, and can increase Soybean production cost.Phosphorus has the effect promoting that soybean nodulation is grown, and can reach the effect of " with phosphorus nitrogen pick-up ", at the Soybean Growth Characters initial stage, the function of phosphorus mainly promotes root growth, and before flowering, phosphorus can promote the growth of the nourishing bodys such as cauline leaf branch.Potassium can promote Soybean Seedlings Growth, makes stem stalk strong resistant to lodging.In addition, the effect of trace element zinc, iron, boron, magnesium, molybdenum etc. is also very important, and appropriate trace element can promote that soybean plant strain grows, and increases soybean yields, improves the quality of soybean.According to the study, often produce double centner soybean and be about absorbed nitrogen 7-9.5 kilogram, phosphorus 1.3-2.0 kilogram, potassium 2.0-3.7 kilogram, also have 1 kilogram, magnesium, sulphur 0.67 kilogram, the trace element of molybdenum 0.308 gram and some amount.
At present, Development of Green Food has become current new rural economy growth point, and Development of Green Food needs nuisanceless fertilizer and coordinates.Root nodule bacterium fertilizer can reduce leguminous crop nitrogen fertilizer amount, and the root nodule bacterium fertilizer produced in the market has three kinds:
(1) solid root nodule bacterium fertilizer: sorbent material mostly is the peat composed of rotten mosses is chocolate or brown powder shape solid, moistening loose, water content 20-35%, and generally every gram of microbial inoculum is containing viable count 1-2 hundred million, and miscellaneous bacteria number is less than 15%, pH6.0-7.5;
(2) liquid root nodule bacterium fertilizer: be as good as stink, every milliliter contains viable bacteria 5-10 hundred million, and miscellaneous bacteria number is less than 5%, pH5.5-7.0;
(3) freeze-dried vaccine formulation: do not add sorbent material is white powder, and bacteria containing amount is higher than peat composed of rotten mosses agent tens times, but application is little in production.
There is following defect in above-mentioned root nodule bacterium fertilizer:
(1) lack high-efficiency root-nodule bacteria strain, microorganism resource lacks, and the bacterial classification of a lot of producer is all utilizing same bacterial strain, and fertilizer variety is single; On the other hand, use that bacterial strain is improper also can bring potential safety hazard, the production bacterial classification of some producers does not just put into production through regular qualification, is also a kind of ill-considered behavior;
(2) production unit is outmoded, and many factories are formed by transformations such as defunct small-sized zymin factory, Gourmet Powder Factory, Citric Acid Plant, and inherently efficiency is low, energy consumption is high for its equipment, produces reluctantly, does not have long-range evolutionary operation(EVOP);
(3) technical matters falls behind, as long as some producer thinks there has been microorganism manure strain, has had corresponding substratum just can produce microbial fertilizer, lacks the monitoring in production process and detection means, the mode of production of the even still small workshop mode had.
