The present invention also provides this microbial fertilizer in preparation prevention rice pest, the application that purify water quality of paddy field, improves rice yield aspect simultaneously.
The present invention also aims to provide described microbial fertilizer to accelerate the application in rice stubble digest process in preparation.
The present invention also provides the using method of described microbial fertilizer, it is characterized in that adding in proportion described microbial fertilizer when rice seed soaking, nursery stage and vegetative period, harvesting aftertreatment rice stubble, in seed soaking, spray the use when filling with root.
Microbial fertilizer of the present invention provides a kind of can carry out after presoaking and germinating at rice paddy seed, can break fast seed dormancy, promote seed germination, strengthen seed resistance, for guaranteeing that full stand, strong sprout lay a solid foundation, for preventing and treating disease, suppressing the generation of insect pest, the resistance of raising crop etc. have played good effect, be the microbial fertilizer of an economical and effective well stimulation simultaneously.In rice field, apply after the present invention, can P and K decomposing fixed nitrogen, and change the trace element in soil, can produce various plants mediator agent, greatly change crop microcirculating state, promote the absorption of nutrient and conversion, strengthen photosynthesis, accelerate cell fission speed, accelerate cell and expand, promote growth, improve output, improve quality, there is sterilization simultaneously and press down worm effect, for common Achlya spp disease, bakanae disease, banded sclerotial blight, rice blast, all produce effect.Microbial fertilizer of the present invention, state of the art is reached advanced world standards, is by multiple beneficial living microorganism process scientific matching, is jointly composited, and has really reached pleiotropy, and unit living bacteria count is not less than 2,000,000,000/milliliter, considerably beyond national standard.
Useful technique effect and using method are embodied in following several aspect:
With after the present invention's seed soaking, can break fast seed dormancy, promote seed germination, strengthen seed resistance, guarantee that the neat seedling of seedling is strong, seedling rate is high; Effectively improve soil physical and chemical property, prevent soil belt poison, prevent and treat the generation of soil-borne disease, Achlya spp disease, bakanae disease, banded sclerotial blight, rice blast; Impel root growth, main root is sturdy, and fibrous root is many; Cold-resistant drought-resistance ability strengthens; Purify water, blue bath obviously tails off; Short control combination, steadily and surely grows paddy rice, strengthens photosynthesis, and short root increases tiller, makes the early growth and quick tiller of tillering, and reaches that seedling is strong, fringe is many, fringe is large, prevents remaining green when it is due to become yellow and ripe late-maturing and de-fertile early ageing; Improve output 17% left and right, improvement quality.
After becoming thoroughly decomposed with microbial fertilizer processing rice stubble of the present invention, can accelerate rice stubble decomposition rate, reduce obnoxious flavour and discharge, decompose paddy rice from poisonous substance matter, solve paddy rice continuous cropping; Increase soil beneficial microbe colony, suppress soil disease and occur, improve rice shoot survival rate, strong rice root; Purifying water body, reduces the harmful organism growths such as blue-green algae, builds ecological water body, creates paddy rice healthy growth environment; Improve utilization rate of fertilizer, promote paddy growth, increase rice yield, improve rice quality.

Experimental example 1: the application of microbial preparation of the present invention aspect paddy rice
Nan Mazhuan village, Lankao, Henan is the best place of rice cultivation always.2006, on the paddy rice of the Nan Ma of the present invention village, be widely used, and obtained unusual effect, be embodied in: soil has obtained improvement, seedling rate is high, Miao Qi, Miao Zhuan (as Fig. 2), well developed root system is (as Fig. 3-1, 3-2), striped blight and planthopper harm have effectively been controlled, make thousand seed weight increase 0.7g, the average yield per mu of control group is 396.65kg, and the average yield per mu of demonstration group is 466.55kg, than control group mu volume increase 69.9kg, output improves 17%, the omnidistance usage quantity that reduces by 30% fertilizer and pesticide, rice milling yield is high and rice matter is good, and purchasing in the hearing of rice bag ground price of Held in Beijing, won expert, professor's a consistent favorable comment!
Experimental example 2: the application of microbial preparation of the present invention aspect paddy rice
Big area blue-green alga bloom has been broken out in Nan Mazhuan paddy fields, Lankao, Henan in June, 2007, company to part peasant household paddy field application by throwing them after the present invention, make the blue-green algae in rice terrace controlled.Breaking out the rice terrace of blue-green algae and using in rice terrace of the present invention, choose at random the plot of a square metre, with grate, fish for the suspended biological (comprising blue-green algae) in water, after taking-up, be placed on after hanging drip-dry moisture in the string bag and weigh: using field of the present invention blue-green algae material is 0.305kg (mean value), do not use rice field of the present invention, field blue-green algae material 3.02kg, and used the whole atrophys of blue-green algae of the present invention, water quality limpid (as Fig. 4-1,4-2).
Experimental example 3: the application of microbial preparation of the present invention aspect paddy rice
2008, Jiangsu Province's Yancheng City, scientific research, popularization, master of instruction carry out the on-the-spot product of surveying to Xin Yang farm to using paddy rice of the present invention " Wu-Yu-Geng 3 ": under same medium soil fertility condition on the lower side, the in the situation that of 5 kilograms of tillering fertilizer and every mu of average Shaoshis of ear manuer, use after the comprehensive treating processs such as microbial inoculum is soaked seed, repair in seedbed, filling root, foliage-spray, do not use rice tillering of the present invention less, and cane have canescence mould; Use paddy rice figure the mean tillering rate of the present invention many compared with control group, and cane is sturdy, health (as Fig. 5-1,5-2).Use every mu of number of productive ear of the present invention to reach 23.09 ten thousand, than untapped, increased by 18.28%, every mu of per unit area yield is up to 678.54 kilograms, than untapped volume increase 15.47%.Expert conclusion: Rice Production is used this novel " microbial inoculum ", does not only increase user's cost, and drops into and reduce, and output increases, and abridged edition increases income significantly.
Experimental example 4: the application of microbial preparation of the present invention aspect paddy rice
Qiyang,hunan red soil experiment centre: sum up use paddy rice arrow leaf of the present invention large, photosynthetic strong, heading is neat, growing way is good, do not use paddy rice early ageing of the present invention serious, ear irregular, rice blast big area occurs, growing way weak (as Fig. 6-1,6-2).Use rice field of the present invention to promote the utilization ratio of soil phosphorus, potassium, significantly increased that paddy rice effective fringe, grain number per spike, the real grain of fringe are heavy, thousand seed weight, reduce paddy rice ghost rate, volume increase 10%-15%.
