Description
Technical field
The invention belongs to environmental protection technical field, relate to a kind of crab shell powder regulation and control matrix that adopts and promote Festuca Arundinacea floor space effectThe method of fruit.
Background technology
Urban lawn planting system is that the several functions such as collection ecological regulation and control, beautification of landscape, CRUX and entertainment areThe ecological engineering of one. It is the important component part of urban Compound greening system, is not only maintaining compound urban ecological systemBalance aspect plays an important role, and view and landscaping effect that it brings are other construction project of city and project instituteIrreplaceable. Why lawn is playing the part of important role in urban ecological system, has special ecology owing to itSystem service functions. The value of ecosystem service of turf establishment system is mainly: lawn plant can be effective by reducing groundRadiation and absorbing carbon dioxide, alleviate " urban heat island " effect; The oxygen that photosynthesis of plant discharges, can improve urban atmosphereQuality, Gas regulation humidity; Plant energy absorption and sorption and the pollutant of degrading in environment; Lawn also can be people's motion, stopsBreath, strolling about or have a rest and enjoying life provides activity space; The peculiar view in lawn and landscaping effect, bring beautiful impression.Now, turf establishment system construction has become one of the important content that must consider in modern city ecological construction, and lawn is greenChange area and quality and become the important objective standard of evaluating city environmental quality. In addition, turf establishment system is also to show nowFor a window of urban society's development level and economic strength, it is improving City Investment Environment, is attracting foreign investment, promoting tourismEtc. aspect all play an important role.
Turf establishment system construction present situation can be summarized as both at home and abroad: first, external per capita green grassland area is larger,Area as per capita in Washington is 45.7m2, human relations pier 30.4m2, may train rubbish 70.5m2, Warsaw 70.0m2, Moscow 44.0m2. Secondly, turf establishment had become a large efficient ecological industry of a lot of developed countries already, and output value growth rate is much larger than samePhase economic growth rate, if U.S.'s annual value of production is with 18% rapid growth; Lawn Industry is number two in U.S.'s crop industry, and itSame aviation, electronics etc. become one of country's ten large industries in the lump. Have, turf establishment industry has also driven machine-building, society's clothes againThe fast development of the related industries such as business.
Compared with advanced international standard, Chinese turf establishment system construction is all in planting scale, quality, management and research and development etc.There is gap in many-side.

Should say, the selection of turf establishment mode, is directly connected toThe success or failure of turf establishment. Certainly, turf establishment is Cheng Ping rapidly, and produces a desired effect, and also depends on to a great extentFeatures of Ecological Environment, and administrative skill level after Cheng Ping.
Although the advantage that lawn greening system has many worth people to speak approvingly of, this at all can not cover lawn greening and depositShortcoming, dependence on import as long-term in grass seeds, according to incompletely statistics, annual China import grass seeds quantity is up to more than 7000 tons;Therefore in this case, research and development improve turf establishment primary growth performance, promote the technology of lawn plant seed planting efficiency, willA very significant job.
On the other hand, China's crab resource is very abundant, probably has 600 kinds, is mainly divided into fresh water crab and sea crabs. Every year allThere is the low value sea crab of up to ten thousand tons to be processed to canned crab meat outlet, leave a large amount of processing pin material-crab shells. According to investigations, from 1997Year, Zhoushan, Zhejiang Province crab shell output annual mean was 33754t to 2002. At present, due to the utilization rate of technical problem crab shellNot high, except small part coarse crushing processes raw material as fish meal, also have part to produce for chitin, but due to production processEasily produce problem of environmental pollution, the chitin manufacturing enterprise in Zhoushan is forced to stop production. Abandoning in a large number of crab shell caused environmental pollutionWaste with resource.
In crab shell, contain protein, chitin, calcium carbonate, calcium phosphate, fat-soluble carotenoid, aromatic substance andThe Multiple components such as liposoluble vitamin (as VitAVitE). Tao Xueming etc. further analyze and show crab shell component, crabIn shell the content of calcium, phosphorus, iron be respectively 326,176,24mg/g, calcium-phosphorus ratio is 1.85:1, can be used as good mineral and mendsFill agent. Chitin is in current crab shell component, to be studied maximum a kind of materials. In the experiments such as Wang Chunwei, can see,Within the scope of 0%～0.25% chitosan concentration, the increase of the long and root personal attendant concentration of the weight in wet base of radish seedling, dry weight, bud and increasing, superCross this concentration range Growth of seedling on a declining curve. Yu Mingge etc. have also obtained similar conclusion: low concentration promotes growth, heightControl of the concentration growth. Through the shitosan winter wheat seed after treatment of suitable concentration, the GA in its endosperm3Content and AMSActivity significantly improves, and then affects the synthetic and relevant physiological biochemical reaction of induced enzyme in seed, and this is that it promotes growth of seedlingMechanism. Except chitin, in crab shell, also there is the materials such as calcium carbonate, Poonia and Bhumbla research are found, apply carbonic acidCalcium can make content of calcium and magnesium in barley (HordeurnvulgareL.) body, and Ca/Na ratio and output (dry weight) slightly increaseAdd.
