Description
Technical field
The present invention relates to a kind of soil improvement agent, particularly relate to a kind of modifying agent that is used for alkaline land soil.
Background technology
The saltings is meant that (particularly upper soll layer 0-20cm) contains soluble salts such as a large amount of sodium-chlor and yellow soda ash in the soil, has a strong impact on the growth of conduct.Natural condition such as the saltings is generally short of rain in the weather arid, steam output is big, physical features is low flat, ground water table is high, salinity is big and human activity influence formation down.Large-area saltings, China the Northeast pH value is more than 8.0, and present existing alkaline land improving technology has: 1, physically improved: as level land, in time loosen the soil, too high landform etc. to the soil; 2, hydro project improvement: supporting like irrigation and drainage, storage fresh water on saline, washing salinity by irrigation, measures such as underground salt discharge; 3, chemical modifying: the soil improvement agent that uses on the domestic and international market, solid-state and liquid state are arranged, selected material is conventional has gypsum, desulfurated plaster, flyash, sand, humic acids etc.The consumption that has is big, is not easy to construction and uses, and the cost that has is high, and fluent material has various acid and hydrogen salt, and wherein use cost and effect are the key points that influence is promoted.
Patent publication No. is CN102199061A; Open day is the patented claim of 2011.9.28, discloses a kind of mikrobe alkaline land modifying agent, is that core material combines solids such as brown coal powder, chimney soot to form again with subtilis, photosynthetic bacterium, yield increasing fungus, milk-acid bacteria etc.; Characteristics with safety and environmental protection; Can also use as the fertilizer of plant, but this modifying agent cost is higher, is difficult to apply.
The patent No. is that the patent of ZL00100436.0 discloses a kind of effectively alkaline land soil modifying agent of iron and phosphorus content that can activate in the soil; Hydrocerol A, wood acid, xanthohumic acid, FUMARIC ACID TECH GRADE, humic acid, tetra-sodium, oxysuccinic acid etc.; Action effect to soil is better, easy to use, cost is lower; But just reduce pH in soil with various acid, it falls, and salt removes the effect of alkali and thoroughness that soil is improved is still waiting further improvement.
The patent No. is that the patent of ZL01136114.x discloses a kind of soil efficient improver; Use high molecular weight water soluble polymer and solid acid to activate conventional sulphur, gypsum and the organic peat that can improve salinized soil; This modifying agent can effectively promote plant on the saltings, to grow; But this modifying agent is just improved soil from single angle, and the saltings is difficult to thorough improvement.
Summary of the invention
The technical problem that the present invention will solve provides that a kind of cost is low, instant effect, improve alkaline land modifying agent completely.
For reaching above-mentioned purpose, a kind of alkaline land modifying agent of the present invention, it comprises pulvis and aqua,
