The invention also relates to a preparation method and the application of the saline-alkali soil conditioner. The saline-alkali soil conditioner is prepared by blending the low-cost raw materials according to the specific proportion, is simple and convenient to use, and is capable of adjusting the pH of soil, increasing soil organic matters, promoting the formation of a soil aggregate structure and improving the permeability of the soil so as to comprehensively improve the saline-alkali soil from multiple points of view; therefore, the saline-alkali soil conditioner has wide popularization and application prospect.
Description
Technical field
The present invention relates to agricultural environment child care and recovery technique field, be specifically related to a kind of saline-alkali land soil conditioner.
Background technology
Salting of soil and Secondary Saline problem worldwide extensively exist, and have become the resource constraints of world's Irrigation farming Sustainable development.China's saltings area about 2,340 ten thousand hm
2, northwest, North China, West of The Northeast China and coastal region all have distribution, and type is various.Improvement, development and utilization saltings resource, can alleviate because population constantly increases the contradiction caused between population and soil, and to maintenance agricultural sustainable development, improve the ecological environment, thrust zone economy, society and Ecological Sustainable Development are significant.
At present, alkaline land improving is still a complicated engineering, and domestic and international Saline-alkali Field Control technical study is a lot, and waterways salt discharge is taked in varieties in saline-alkali areas, inland, causes polluting water source, downstream, causes soil, downstream secondary salinization; In biological modification measure, only focus on big area kind grass, still lack the functions such as forest ecology protection.And these methods are not that investment is excessive, take effect exactly slow.Using soil improvement agent is one not only economy but also method easily, and it can improve soil physical and chemical property, strengthens soil soil conservation water retention capacity, strengthen Trace Elements in Soil validity; Soil Microorganism and enzymic activity, suppression sex pheromone can also be improved simultaneously, strengthen plant resistance to environment stress etc.But in various soil improvement agent, the high cost of the macromolecular compound of synthetic and its latency environment Pollution risk existed and limit its widespread use; There is improved effect comprehensively or have the weak points such as negative impact in various degree in single soil improvement agent.
Summary of the invention
The object of this invention is to provide a kind of fill a prescription simple, cost is low, instant effect and comprehensively improve the modifying agent of alkaline land soil performance.Described modifying agent is mixed with specified proportion by desulfurated plaster, humic acid and citric acid three kinds of compositions.
Saline-alkali land soil conditioner of the present invention is applicable to saline-alkali soil, and the parameter of described alkaline land soil is preferably: pH value 10 ~ 12, electric conductivity 2000 ~ 3000us/cm; More preferably pH value 10.5 ~ 11.5, electric conductivity 2300 ~ 2700us/cm.
Specifically, saline-alkali land soil conditioner provided by the invention is grouped into by the one-tenth of following mass percentage: desulfurated plaster 45 ~ 65%, humic acid 25 ~ 35%, citric acid 5 ~ 30%.
Described modifying agent is preferably grouped into by the one-tenth of following mass percentage: desulfurated plaster 49 ~ 56%, humic acid 28 ~ 32%, citric acid 12 ~ 23%.
The described modifying agent further preferred one-tenth by following mass percentage is grouped into: desulfurated plaster 51 ~ 54%, humic acid 29 ~ 31%, citric acid 15 ~ 20%.
The present invention is found by a large amount of practical experience, by by desulfurated plaster, humic acid and citric acid three with specified proportion with the use of, can realize synergy, the over-all properties of alkaline land soil is significantly improved, is especially beneficial to the plantation of farm crop on soil.
Desulfurated plaster of the present invention selects fire coal or oilmill administering the industry byproduct obtained after contained sulfurous gas in flue gas.In the preferred described desulfurated plaster of the present invention, terra alba CaSO
42H
2content>=85% of O and H
2content≤12% of O.
Described humic acid can select the former powder of humic acid.Purity >=60% of preferred described humic acid and organic content >=70%.
The optional technical grade Citric Acid, usp, Anhydrous Powder of described citric acid.Purity >=80% of preferred described citric acid.
Present invention also offers the preparation method of described saline-alkali land soil conditioner; Be specially: get desulfurated plaster, humic acid and citric acid, cross 80 ~ 120 mesh sieves respectively, mix.
The present invention protects the application of described saline-alkali land soil conditioner further.
Described application method is specially: added in alkaline land soil by described modifying agent.The parameter of described alkaline land soil is preferably: pH value 10 ~ 12, electric conductivity 2000 ~ 3000us/cm; More preferably pH value 10.5 ~ 11.5, electric conductivity 2300 ~ 2700us/cm.
When practical application, in every mu of alkaline land soil, preferably add 1000 ~ 1100kg modifying agent.
The alkaline land soil adding described modifying agent may be used for Planting Crops.The present invention is by putting into practice discovery in a large number, planting vegetable in the alkaline land soil that with the addition of described modifying agent, the parameters such as the percentage of germination of vegetables, germinating energy, germination index, vitality index can be significantly improved, thus realize the successful plantation of vegetables in alkaline land soil.Vegetables of the present invention are preferably brassicaceous vegetable, as Chinese cabbage (Brassicarapapekinensis), Plantula Brassicae chinensis (BrassicacampestrisL.ssp.chinensisMakino), green vegetables (Brassicachinensisvarchinensis), rape (BrassicacampestrisL.), cabbage mustard (BrassicaalboglabraL.H.Bailey) etc.
Saline-alkali land soil conditioner provided by the invention is made up in specific proportions of desulfurated plaster, humic acid, citric acid three kinds of raw materials, following excellent effect can be realized: described saline-alkali land soil conditioner can strengthen soil calcium ion content, the sodium ion that displacement soil colloid adsorbs and magnesium ion, sodium hydrophilic colloid is made to become calcareous hydrophobic colloid, thus improve Soil structure and permeability, serve the effect of desalination and the suppression accumulation of salt in the surface soil, meanwhile, calcium can strengthen the drought-resistant ability of crop as a kind of nutritive element; Containing a large amount of organic in described saline-alkali land soil conditioner, physico-chemical property and the physical and mechanical properties of soil can be improved, promote that soil aggregate is formed, improve Soil ventilation performance, be conducive to the drip washing of salinity, meanwhile, organic matter has stronger absorption property and higher positively charged ion replacement ability, to Na
+, Cl
-have very strong adsorption, and an organic matter source that to be plant nutrient important, organic matter decomposition can provide comprehensive nutrient for plant growth, thus strengthens the ability that crop survives in adverse circumstance; Directly reduce saltings pH value containing acid mass-energy in described saline-alkali land soil conditioner, make it be more suitable for the growth demand of crop.Saline-alkali land soil conditioner provided by the invention, by changing soil pH, increasing the various the mechanism of improvement such as the soil organism, ion-exchange, have quick and continual and steady remarkable improved effect, and raw material sources is extensive, with low cost, environmental friendliness, non-secondary pollution, is easy to spread.
