Abstract
The invention relates to a preparation method of desertification land modified materials through steam shattering straws and solid state fermentation, which consists of the following steps, first, pretreatment is given to straws, thus obtaining the straw raw materials shattered by steam, after being shattered, straws are put together with wheat bran for solid state fermentation so as to produce functional materials with biological fertilizer and plant disease prevention and treatment, then the materials are remixed with degradable bacterial cellulose with strong water absorption. The products can improve the microstructure of soil, and reduce the using amount of active water retaining agent, the great amount of soil beneficial microorganism enriched has the functions of water storing, soil moisture conservation, and nutrient element slow releasing, etc., so the products are suitable for the mass application of the prevention and treatment of sand land, wherein, the organic content of the products is more than 60 percent, the content of humus is more than 15 percent, and the total number of effective living bacteria is more than 0.3 billion per gram.
Description
Technical field
The present invention relates to a kind of method for preparing sandy land improvement material, particularly a kind of method for preparing sandy land improvement material with the steam explosive-crushing straw solid state fermentation
Background technology
Desertification of land is one of current the most serious ecological environment problem of China, the sandy land area is 173.97 ten thousand square kilometres, account for 18.12% of area, administer and the dynamics that improves, still be in improvement now and desertify the stage at a stalemate though China recent years has strengthened sandy land.Adopting stalk to carry out sandy land improvement begins to use from the nineties in last century in China, the main way at initial stage is to similar abroad, many employing stalks bury to be made anti-sand-protecting barrier or covers sand prevention, but owing to can not tackle the problem at its root, this application mode can only be very limited assist measure.
Because drought and water shortage, vegetation deterioration, soil texture difference are the main drives of desertification of land, therefore, Chinese scholars is recognized moisture self-restraint ability is improved, improved to the soil texture and Vegetation Construction is the essential measure of control desertification of land, and carried out big quantity research, the focus of applied chemistry material improvement once becoming research around these aspects.But because cost is too high, and plant is limited to the specific absorption of a large amount of chemical improvement agents, and long-term application not only can polluted underground water, and can cause soil compaction, destroys ecotope.Therefore, stalk is administered with the effect that improves in desertification of land and is much accounted of gradually again.Studying from existing, is that the sandy land of main raw material is improved the test effect of material and is not less than chemical material with the stalk, compares with simple chemical material to have advantages such as starting material are easy to get, cost is low, the lasting period is long, multiple functional.
At present, most of sandy land improvement materials of China or modifying agent often simply adopt the physical method of mechanical disintegration when utilizing stalk as additive, because pre-treatment is simpler, the stack retting cycle is longer when carrying out compost, product quality is relatively poor, and also fertilizer efficiency is low behind the field.The method that has (CN1534006A) is though from improving the angle of soil fertility, do not have obviously to improve the water-retaining capacity of soil, and the product processing energy consumption is higher; Adopt straw to prepare the report (CN1498941A) of biological activity water conservation modifying agent in addition, but the preparation of its active water-absorbing material needs chemical acid alkali to handle, can produce to a certain degree pollution environment.In addition, because straw nutrition component content imbalance often needs additionally to add a certain proportion of mineral manure, organic nitrogen source, humic acid and scarce metallic compound (CN1257855A) when being used for land reclamation, fundamentally do not reduce product cost.
Summary of the invention
[purpose of the present invention] to utilize stalk to prepare sandy land improvement material pretreatment technology undesirable at existing, there is environmental pollution, and the course of processing needs the extra too high problem of application cost that compositions such as inorganic fertilizer, humic acid, nutrition cause of adding, provide a kind of steam explosive-crushing straw solid state fermentation to prepare the method for sandy land improvement material, handle by steam explosion and solid state fermentation, improve the quality and the characteristic of stalk, the effect that increases bio-feritlizer reduces the technical costs of desertification of land control to reduce the consumption and the environmental pollution of chemical fertilizer.
[thinking of the present invention] steam explosive-crushing straw solid state fermentation provided by the invention prepares the method for sandy land improvement material, utilize the stalk fibre characteristic to make the functional product that is similar to the chemical modifying material, utilize physics and biological process that stalk is handled, adopt steam explosion and solid state fermentation to improve the water-absorbent of material respectively, the content of humify and nutritive element, then with degradable strong absorptive material---bacteria cellulose forms preparation under certain processing condition, not only can improve soil microstructure, obviously improve the soil water storage ability, reduce the consumption of bioactive water retaining agent, and a large amount of soil beneficial microorganisms of enrichment have and retain and conserve soil moisture behind the solid state fermentation, functions such as nutritive element slowly-releasing are suitable for the large-scale application that sandy land is prevented and treated.
