Abstract
The invention relates to an aeolian sandy soil modifier. The modifier is prepared by mixing and fermenting cow droppings, corn straws, furfural residues, sheep droppings, CO(NH2)2 and NH4H2PO4 according to air drying weight proportion of 5500-6500:6000-7000:4500-5500:7000-8000:90-110:90-110. By using agricultural organic solid wastes, the invention effectively improves water retention and fertility preservation abilities of the aeolian sandy soil and increases organic matters and the contents of rapidly active N, P and K in the aeolian sandy soil.
Description
Technical field
The present invention relates to agricultural and use the soil field, relate in particular to aeolian sandy soil modifier.
Background technology
Sand soil is the soil that forms on wind-blown sand sexupara matter, and this class soil also is a kind of lithology soil.In China, sand soil mainly is distributed in northern semiarid and arid area.From the east to the west, have Hulun Buir, the western Liaohe River, rise in the lattice for a short time, hair crow element, Ku Buqi, cloth of ulan and, rise in the lattice, Padan Jilin, Qaidam, khoum tower lattice, Gu Erbantonggute and Plutarch draw sand soil areal concentrations such as agate is dried.The sand soil area, dry, the temperature difference is big, and the rock physics weathering is strong, constantly forms landwaste and sand grains.The rare sulphur of ground vegetation can not play the lining effect, and under frequent and powerful wind-force deflation, gravel is residual, and fine earth is raised afield, and sand grains then rolls on the face of land, bounds forward, so that quicksand spreads the formation sand soil.Sand soil can be divided into three phases substantially in formation and evolutionary process: 1. flow the sand soil stage.Only growing sparse psammophytic vegetation, plant of mobile sandy ground settled down difficulty, and soil development is not obvious, is in the initial period of soil-forming process.2. the semifixed sand soil stage.Along with plant continues to grow on the sand soil that flows, vegetation coverage increases, and the sandy ground surface is semifixed state, and landform slows down, and the sandy ground surface becomes tight, forms the thin layer skinning, and dyes the dead color that soil ulmin is arranged, the soil profile differentiation.3. fixing sand soil stage.Plant on the semifixed sand soil further develops, and the sand surface skining thickens, and the consolidation that becomes, and soil ulmin accumulation in top layer is strengthened, and soil body differentiation is obvious, and physics, chemical property also have significant change, and then are converted into fixedly sand soil.
At present, sand soil is educated grass, diversion by afforestation, envelope sand and is drawn sand, draws big vast warping, mode such as sand barrier is set prevents and treats, but because the inclined to one side sand of sand soil quality, a little less than water conservation, the fertilizer-preserving ability, organic and available N, P, K content are low, belong to low productive soil, therefore, how to make it become high production soil and carry out agricultural use and then become research tendency.
Summary of the invention
Technical problem to be solved by this invention provides a kind of aeolian sandy soil modifier that improves water conservation, fertilizer-preserving ability.
For addressing the above problem, a kind of aeolian sandy soil modifier of the present invention is characterized in that: this modifying agent is by cow dung, maize straw, furfural dregs, sheep excrement, CO (NH

The particle diameter of described cow dung, sheep excrement is 5～10mm.
The length of described maize straw is 10～20mm.
The particle diameter of described furfural dregs is 2～5mm.
The production method of aforesaid aeolian sandy soil modifier is characterized in that: obtain mixture after at first cow dung, maize straw, furfural dregs, sheep excrement being mixed by proportioning; In mixture, add CO (NH then respectively

4, and add water and make its water content reach 60～65%; Last mixing piles thick trapezoidal of 1.0～1.20m, and tipping gets final product for 3 times behind fermentation 15～20d.
The present invention compared with prior art has the following advantages:
1, owing to contains organic solid castoffs such as cow dung, maize straw, furfural dregs, sheep excrement among the present invention, and these organic solid castoffs contain organic 221.20～243.40g/kg, full N0.32～0.83%, full P0.15～0.40%, full K0.44～0.67%, and the agricultural organic solid castoff controlled contents standard that heavy metal element Hg, Cd, Cr, Pb content are all stipulated less than GB8172-87, therefore, not only can effectively improve water conservation, the fertilizer-preserving ability of sand soil, and increase the content of the organic and available N of sand soil, P, K.
2, the present invention is carried out after the mass analysis as can be seen, the present invention reaches the specification of quality (referring to table 1) of composite fertilizer.
