Description
Technical field
The invention belongs to the environmental ecology recovery technique fields of biological carbon and the tool micro- sheath algae of sheath, are related to biological carbon and combine tool sheath
The cultural method of micro- sheath algae desert crust forming agent.
Background technology
Biological carbon is biomass material (such as sawdust, stalk, animal waste) under conditions of anoxic or anaerobic, passes through heat
A kind of solid-state carbon rich material matter that chemical conversion obtains.It is numerous research shows that biological carbon is ideal soil conditioner, improving soil
Earth nutrient improves soil texture, improves soil water-retaining nutrition-retaining ability, improves edaphon abundance, diversity and improves group
Fall structure etc. significant effect.
Have the micro- sheath algae of sheath (Microcoleus vaginatus) be a kind of terrestrial filamentous cyanobacteria, extreme drought, high temperature,
Extremely strong adaptability is shown in the unfavorable habitats such as high salinity, high ultraviolet radioactive, is the most abundant advantage of Desert Area algae skinning
Pioneer in species and deserta During Succession plants a colony biology.The tool micro- sheath algae biological breadcrust of sheath restores in deserta
Have in initial period and reconstruction process and accelerates soil forming process, enhancing erosion-resisting characteristics, increase soil fertility, promote seed
Library is established and the remarkable effects such as colonization of vascular plant, is arid biogeographic zone desertification treatment, the good pioneer of soil remediation,
It is also the precondition of arid-desert areas vegetation succession.But tool the micro- sheath algae of sheath desert artificial infection formed biological breadcrust and
The environmental factors such as inoculum density, matrix nutrition, husky water content, temperature are closely related；One piece of complete skinning clear-cutting forestland time from
Several years to the more than ten years etc., the period was very long；And desert biological breadcrust can accelerate desertification process once being destroyed.Therefore
Being seeded in desert surface formation biological breadcrust using the tool micro- sheath algae of sheath also needs to seek new approaches and methods.
Currently, the sustainable approach that the mankind are still effective, simple and practicable without administering the green of arid biogeographic zone Desertification.
Traditional measure such as afforestation, straw checkerboard barrier sand-protecting barrier and clay sand-protecting barrier of checking winds and fixing drifting sand only has temporal effect in subrange, and
And time-consuming and laborious, inefficiency, non-permanent, the basic countermeasure for solving the problems, such as soil desertification.Biological carbon combines the tool micro- sheath algae of sheath can
Show to form new bio crust forming agent in desert, biological carbon therein provides carbon battalion for the growth and breeding for having the micro- sheath algae of sheath
Foster, moisture and good proliferation space keep its sand-fixing effect more preferable, more permanent and simple and practicable.Our research group's joints are beautiful
North Carolina State University of state has studied influence of biological carbon (rice hull carbon) addition to the micro- sheath algae growth of tool sheath, Yi Jigu for the first time
Husky effect.The result shows that when ratio of the biological carbon in sand is 2%, has the micro- sheath algae biomass (being indicated with Chlorophyll-a Content) of sheath
Maximum, sand-fixing effect is best, and the addition of biological carbon has been obviously promoted the formation of husky surface biological skinning under drought condition, is good
Soil Biological Crusts method.
Invention content
The purpose of the present invention is to provide the preparation method that a kind of biological carbon combines tool sheath micro- sheath algae desert crust forming agent, this hairs
