Plant pathogen: Plant pathogen is to infect to parasitize plant and lead to infectious disease Biology.The mostly non-obligate parasite of heterotroph.It is not the decision to form plant disease though pathogen has pathogenecity Factor is less unique factor.It can cause to fall ill, it is mutual to further depend on host plant, pathogen and environmental condition three The result of effect.Known pathogenic object mainly has: fungi, a kind of important eukaryotic microorganisms.Generally branch or regardless of The filamentous of branch.Some have diaphragm in mycelia, and mycelia is divided into multiple cells;Without chloroplaset and chlorophyll, majority tool is thin Cell wall.Some fungies are unicellular, cell-free wall.It is all heterotroph, it is parasitic (being mostly facultative parasitism in addition to minority) or saprophytic.Have Two kinds of modess of reproduction of vegetative propagation and sexual propagation.Vegetative propagation mainly generate sporangiospore (the tool flagellum having, can move about, Claim zoospore) or conidium (the external spore generated from mycelium or on conidiophore that mycelium is differentiated to form Son), it is more typical with the latter.Zoogamy can produce various sexual spores, wherein there is the ovum for the formation that directly mates by gametocyst Spore and zygosperm have the basidiospore for generating the ascospore in ascus or being formed in load.The history of life of fungi wraps Include the alternation of generations process of asexual reproductive phase and sexual reproductive phase.The asexual spore that imperfect stage generates can continuous several times production It is raw, it is the cause of disease of plant disease epidemics;Perfect stage, which mostly occurs, infects the later period in disease fungus or after suspend mode, sexual spore Son only generates once, mostly the source of disease First aggression.Fungi can penetrate plant cuticula and epidermis and cause a disease.Nosomycosis is Most a kind of diseases, every kind of crop have several fungal diseases in plant disease, more up to tens kinds.It common are black powder Disease, rust, powdery mildew and downy mildew etc..But some fungies have antagonism to other pathogens;Some colonize in other cause of diseases On object or insect, there is certain influence to the growth and decline of pathogen in nature and pest.Bacterium, a kind of lesser protokaryon are unicellular micro- Biology.It can the types such as bulb separation bacterium, bacillus, spirillum.There are cell wall, no chlorophyll, heterotrophism is mostly saprophytic.Generally suffer from Raw position difference and number not equal flagellum, some also gemma and pod membrane.Observation and discriminating bacteria mostly use Gram's staining Method.Plant pathogenetic bacteria is Gram-negative mostly, brevibacterium, and bacterium is bred rapidly in a manner of fragmentation, stomata, skin from plant The nature aperture such as hole, nectary and wound invade host.Bacteriosis is mainly seen in high angiosperm, on cultivated plant compared with It is more.No matter field crop or fruit tree, vegetables have one or more of bacterial diseases, are more common in grass family, pulse family and Solanaceae especially Crop.Common disease has the bacterial leaf-blight of rice and cecospora spot, the ring rot of potato, Solanaceae and the blueness of other crops withered Disease, the soft rot of brassicaceous vegetable, the angular leaf spot of cotton and the canker of citrus etc..Bacterialo wilt disease and the pears fire of corn Epidemic disease often results in worldwide harm.Bacterium substance and mycoplasma, bacterium substance are that an analogy bacterium is simpler, can be carried out autonomous generation The known minimum prokaryotes thanked.Cell-free wall, cell outside only have the plasmalemma of unit membrane structure.Thallus is in irregular ball Shape, filiform, helical form or the variforms such as unsetting.Only in the special culture medium of complicated component, majority also needs supply outer Source cholesterol could be grown.Form, structure and the bacterium substance phase reacted with infect humans and animals to antibiotic of mycoplasma Together.Its thallus at least a certain stage twist, can be grown on artificial medium greatly.It has been found that nearly hundred kinds of plants can be by Mycoplasma colonizes in the screen casing of host plant bast and causes disease.Citrus ossifys germ and corn stunting disease pathogen etc. all It is this kind of pathogen.There are also some thallus not twist, cannot grow on artificial medium, there is no classificatory science life Name, and temporarily it is known as mycoplasma.Mulberry wasting disease, jujube witches broom, aster yellows pathogen all belong to such.Rickettsia-like organism or class Richettsia bacterium is a kind of pathogen parasitized in flora conduit or screen casing, there is smooth or undulatory cell wall, without thin Karyon.The bacterium of form Richettsia similar with structure or certain Corynebacteriums, but cannot be in the general culture medium of culture bacterium Upper growth.The rickettsia-like organism that some are colonized in conduit since 1978 is successively separately cultured success, wherein there is gram Negative bacteria and positive bacteria.But not yet cultivating can't successfully determine in classificatory status.Virus and viroid, in work Body cell endoparasitism proliferation does not have cyto-architectural life entity.One complete viremic individuals is known as virion or virion Son.It is made of a kind of nucleic acid and protein coat.There are also coatings outside plastochondria for some viruses.Virus is only under an electron microscope Just it is observed that their shape.The virion for infecting plant mainly has rod-shaped, linear and spherical 3 seed type.Its heredity What character and pathogenicity were determined by nucleic acid, most of viruses are ribonucleic acid (RNA) single-stranded structures, and minority is DNA (DNA) double-strand or single-stranded structure.Invade host plant living cells is viral nucleic acid, and it is thin that protein coat is then left on host Except born of the same parents.Matter and energy of the viral nucleic acid in host cell using cell is copied into novel nucleic acids, and encodes synthetic proteins Matter shell is then assembled into new virion.With the presence of the different plastochondria of the several characters of plant virus, when host's difference When, different plastochondrias can be proliferated as different strain or mutant, and the pathogenicity having nothing in common with each other passes virus mediator and antigenic characteristic, very It is also different to the plastochondria shape having.Virus is easy to mutate (natural mutation and induced mutations).Some virus contains several grains Body, only these types of plastochondria could show whole characters of the virus, have size if alfalfa mosaic virus not when existing simultaneously Deng 5 kinds of plastochondrias.Plant virus is the important pathogen object for being only second to fungi.Field crop and fruit tree, vegetables have several or several Ten kinds of virosis, some harmfulness are very big.The virosis outstanding for having Cereal and potato in production, the virosis of tobacco, The brassicaceous vegetables such as rape virosis, tomato and melon etc. virosis, citrus and the virosis of apple etc..Viroid is Some virulence factors for containing only infectivity low molecular weight rnase are nature simpler pathogens smaller than virus. Known viroid is the cyclic annular ribonucleic acid being covalently latched, and can replicate in plant soma and cause disease.Viroid with So-called " satellite virus " is different, and viroid is replicated in host cell does not need other viral assistance participations, and satellite virus Though ability reproducible proliferation also must be existed simultaneously in host cell with corresponding plant virus without protein coat.Line Worm, quantity is more, and distribution is wide, and the nematode for parasitizing plant has hundreds of, and almost every kind of crop has.Mostly cause harm below portion The root divided and storage organ, also there is stem of causing harm, (see the nemas) of Ye Hehua.In addition to above-mentioned 7 class, there are also some secondary Pathogen.Such as the streptomyces actinomyces in actinomycetes, plant root tuber, stem tuber disease can be caused, including potato tubers Shot hole etc..Red rust algae in algae can cause algae pinta on the blade of tea tree and many other evergreen trees.Minority tool flagellum Protozoan can also cause the tropical crops disease such as coffee and coconut.

Fermentation/microbial fermentation: microbial fermentation refers to using microorganism, and under appropriate conditions, raw material is passed through Specific metabolic pathway is converted into the process for the product that necessary for human is wanted.Microbial fermentation production level depends primarily on strain sheet The hereditary capacity and condition of culture of body.The application range medical industry of Fermentation Engineering, food industry, energy industry, chemical industry, Agricultural: plant modification gene;Biological nitrogen fixation;Engineering bacterium for killing insect biological pesticide;Microorganism nutriment.Environmental protection etc..Micro- life Object fermentation process requires to be divided into aerobic fermentation and anaerobic fermentation according to fermentation condition.Aerobic fermentation method has liquid surface culture hair Ferment, in porous or granular solids media surface top fermentation and logical oxygen submerged fermentation several method.Anaerobic fermentation is using obstructed The submerged fermentation of oxygen.Therefore, no matter it is aerobic can be realized by deep drainpipe with anaerobic fermentation, this culture has As soon as completing in the cylindrical fermentor of the high ratio of sizing, operating method can be divided into following several.Batch operation: substrate is primary It is packed into tank, inoculation is reacted under optimum conditions, by after a certain period of time, the whole is taken out.Semi-batch behaviour Make: also referred to as stream plus formula operation.Refer to and first a certain amount of substrate is packed into tank, inoculation starts reaction under optimum conditions.Reaction In the process, specific restricted substrate is sent into reactor, restricted concentration of substrate is in a certain range in tank to control, and reaction is eventually Only the whole is taken out.Batch operation repeatedly: taking out part reaction system after the completion of batch operation, remainder adds again Enter substrate, then is carried out by batch operation.Semi-batch operates repeatedly: after the completion of streaming computing, part reaction system is taken out, it is remaining Part rejoins a certain amount of substrate, then carries out by stream plus formula operation.
Continous way operation: after reaction starts, on the one hand substrate is continuously fed in reactor, while again reaction solution It continuously takes out, reaction process is made to be in stable state, reaction condition does not change over time.Batchwise is sent out in batches Ferment is also known as batch culture, and common batch fermentation process is using single tank deep layer batchwise in fermentation industry.Each point It criticizes fermentation process all to undergo inoculation, growth and breeding, thallus aging and then terminate to ferment, finally extracts product.This process exists Under the condition of certain culture solutions dominates, microorganism is experiencing by raw to a series of dead changes phases, in the process of each variation In restriction all by thallus self character, be also affected by the surrounding environment.Only correctly recognize and grasp a series of this variation Process is just conducive to control fermenting and producing.Fed-batch fermentation method, also known as semicontinuous fermentation or Semi-continuous cultivation refer to and are dividing During wholesale ferment, the cultural method of fresh culture is intermittently or continuously added.Compared with traditional batch fermentation, advantage exists In making to maintain very low substrate concentration in fermentation system.The advantages of low substrate concentration are as follows: 1. can remove and quickly utilize carbon source Reptation behavior, and cell concentration appropriate is maintained, make the contradiction that will not aggravate oxygen supply;2. culture medium is avoided to accumulate toxic metabolite Object.Continuous fermentation method, Continuous Fermentation Processes are when microculture is to logarithmic phase, in the fermenter on the one hand with certain speed On the other hand fermentation liquid is continuously discharged at a same speed again, makes by continuously stream plus fresh liquid culture medium The growth of microorganism and metabolic activity remain vigorous stable state in fermentor, and pH value, temperature, nutritional ingredient is dense Degree, dissolved oxygen etc. are all kept centainly, and are adjusted from exterior, are maintained thallus under consistent growth speed and are carried out continuously Growth and fermentation, thus * * improves the growth efficiency and utilization rate of equipment and installations of fermentation.It is open to continuously ferment, in open company In continuous fermentation system, the microbial cell in culture systems flows out, cell rate of outflow etc. together with the outflow of fermentation liquid In neoblast formation speed.Therefore in this case, cell concentration can be made to be in certain stable state.In addition, last outflow Fermentation liquid as part return (feedback) fermentor reused, then the device is called the circulatory system, and fermentation liquid does not repeat The device used is called the not circulatory system.It is closed to continuously ferment, in closed system of continuously fermenting, make with some way Cell is always held in bioreactor, and is continuously increased its quantity.Under the conditions of this, certain limiting factors are biological anti- It answers in device and changes, last most cells are dead.Therefore in such systems, it is impossible to maintain stable state.It is closed Continuously fermenting can be reequiped with open continuous fermentation device, as long as being recirculated using part thallus.Another method It is to be placed in equipment using spacer or filler, grows thallus above, it is thin without cell or institute's band when fermentation liquid flows out Born of the same parents are few.The application range of fermentation has: medical industry, food industry, energy industry, chemical industry, agricultural: plant modification base Cause;Biological nitrogen fixation;Engineering bacterium for killing insect biological pesticide;Microbiological feed.Environmental protection etc..
Agricultural organic waste-stalk resource: a kind of stalk being used as resource system.Chinese farming Object stalk annual output is about 700,000,000 t or so, is arranged first of the world.The stalk harvested every year removes 28,000,000 tons of stalks for being used for papermaking With the 2.13 hundred million t stalks as feed or feedstuff, makes fertile returning to the field and collect 1.089 hundred million t of loss, can be used as the energy and be subject to The stalk total amount utilized is 3.761 hundred million t (being shown in Table 1).
Although the stalk resource technology of China grows a lot, related work also achieves great success, total water Flat also very backward, there is also problems for stalk resource technology: (1) straw-returning.Agricultural machinery problem first, stalk also Tanaka's agricultural machinery be it is essential, crush and turn over and all use agricultural machinery, with the increase of crop-residue incorporation, China makes It is common de- to cut machine and rotary cultivator has been unable to meet the actual needs of straw-returning.Secondly for the stalk quantity of returning to the field, Also some problems are deposited.The suitable returning to the field amount (air dry weight) of rice, wheat stalk is advisable with 3000 ~ 4500 kilograms/hectare, corn Stalk is advisable with 4500 ~ 6000 kilograms/hectare;The plot of one Nian Yizuo and the high plot of fertility can also be appropriate high, and in water Field and the low plot of fertility will be lower, general annual per hectare 3000 ~ 4500kg of returning to the field stalk soil can be made to have Machine matter content not but not decline, can also improve year by year, but most of China rural area returning to the field amount does not all reach requirement also.Again, Applying the stalk amount of people and returning to the field mode in also Tanaka should make corresponding changes with the difference of crop and its plantation area.Such as: On the period of returning to the field, rice field is the sooner the better, if by rice straw heap it is ripe after again returning to the field it is more significant than direct returning to farmland effect;? In returning to the field method, the returning to the field of the dry crops such as corn, sorghum should be turned in returning to the field, to keep the stalk of high-moisture rotten rapidly Solution.Since carrying out Planter industry structure adjustment, traditional crop will change to industrial crops, and industrial crops want returning to the field technology Ask high, the rough returning to the field technology of use is not able to satisfy these requirements, so that agricultural crop straw is largely thrown aside in road And stream, or burn.Finally, be exactly field management not enough in place.There are many areas just no longer to manage after straw-returning, lacks The weary abundant decomposition of stalk for guaranteeing underground with reasonable measure in time, by crop utilization.Microorganism is in decomposing straw in order to prevent Nitrogen is striven with crop, should also supplement with a certain amount of instant nitrogenousfertilizer is applied, guarantee the fertility of soil full period;It, must note while returning to the field The prevention and treatment of meaning agricultural land, applies people Tanaka again, can prevent pest and disease damage in this way after thering is the stalk of disease crop to answer compost maturity Sprawling.(2) gasifying stalk.Existing pyrolytic gasification technology mostly uses air gas gas making method, and the calorific value brought about the desired sensation is lower (5000kJ/m3 or so), and there are also tar problems.In the process for promoting gasification central gas supply technology, due to Chinese countryside Economic base it is also very weak, self-raised fund is difficult, and many demonstration projects are out of service just because of tar blocks pipeline.Just For peasant, the level of operation and management is lower, and safety in production and safe handling consciousness are poor, and peasant holds always sight to gasification The attitude of prestige, this also influences the normal operation using effect of system.In addition, also having in terms of tar removing, operation steady in a long-term Wait improve.Particularly for rural area central gas supply system, the ratio between investments of gas holder and pipe network reaches 40% or more, improves cost, difficult In carrying out commercialized running, influence further to develop and promote.(3) straw feed is processed.China is in microorganism fungus kind and accordingly Zymotechnique on and fermented stalk feed to all lacking more careful in-depth study in terms of the nutritive validities of all kinds of domestic animals, and The field of research mostly concentrates on ruminant domestic animal.The appraisement system of a scientific unity is also lacked in research and practice, is evaluated Foundation be only limitted to the physics and chemical characteristic of feed product, have ignored its biological nature.(1) stalk stock keeping.It is Chinese annual raw 600,000,000 t stalks are also produced while producing 4.9 hundred million t of grain, a large amount of potato, taro rattan, climing and utilizable vegetation farming in addition Object is far longer than the forage yield in pastoral area, this is huge feed source.If wherein half is used for stock keeping, the production of meat product Amount will increase by 500.Therefore stalk stock keeping is a development trend in Chinese stalk resource.(2) stalk production degradable is fast Cutlery box.The mess-tin indices done using straw pulp of rice and wheat are good, cheap, and nontoxic, pollution-free in production process, former Expect from a wealth of sources.It can degrade quickly after being thrown away, can increase soil fertility, composing environment does not threaten;It is also released without poison gas when burning, Will not constitute a threat to air quality, quite be welcome by environmental protection administration.One apparatus for production line invests 1,500,000 yuan, produces 30,000 daily, often 1,080,000 yuan of annual return, period of recouping investments in equipment 1.5 years or so, existing social benefit had an economic benefit again, should be stalk money from now on One of the developing direction of source technology.(3) it is manufactured using stalk with feces of livestock and poultry aerobic compost or straw compost technology organic multiple Hefei, can proposed large-scale organic fertilizer factory, market prospects are quite wide.(4) condition quite mature in gasification technology Under, the research and development of efficient low-consume Gasification Technology are carried out, build large and medium-sized straw electric generation plant, economic benefit is not allow Doubt.(5) development and exploitation for accelerating agricultural machinery tool, further improve direct returning to farmland technology;It increases in straw-returning skill Art and its research dynamics of influence and regulation method to soil physical chemistry and biological property.(6) reinforce and University Scientific Research unit Cooperate research cooperation and study new technology, expands the approach of stalk resource, improve its utility value.Such as using biogas as the more of tie The road that kind is managed, preparation on a large scale introduce biogas slurry to the market.In short, agricultural straw resource technology is a synthesis Property, marginality science and technology.Various regions agricultural, agricultural machinery, the departments such as herding will reinforce
