Description
Technical field
The present invention relates to soil structure improved addictive technical fields, more specifically to a kind of dust storm semiarid region farmland soil
Earth texture modifier.
Background technique
The water-retaining property and nutrient preserving capability of aeolian sandy soil are poor, and fertility is very low, and mechanical composition is thicker, be with fine sand and middle sand it is more, glue
Grain content only accounts for 2-10%, homogeneous, and physical clay (< O.Olmm) only accounts for 0.1-6.0%, and aeolian sandy soil is distributed in rainfall more
Measure less arid, semiarid zone.The humus content of the soil is low, and the nutrients such as N, P are barren, saturation moisture capacity and field capacity
Lower, therefore, improvement and desert improvement soil find a kind of economical and effective aeolian sandy soil modifying method, for improving middle-and-low-yielding fields
Grain yield, increase arable land, maintenance ecological environment and regional economic development are of great significance.
Currently, the modifying agent of aeolian sandy soil has very much, there are commonly peat, macromolecule organic materials etc..But it is specifically answering
There are still some problems in, and mainly have the following aspects: 1. peat are a kind of excellent soil conditioners, and peat structure is dredged
Pine, ventilating permeable is good, large specific surface area, color be black or brown, bulk density is small, absorption chelant ability it is strong, have it is stronger from
Sub- exchange capacity and salt balance control ability have the function of that stronger drought resisting, disease-resistant, low-temperature resistance, salt resistance are burst.Peat is rich in
The microelements such as a variety of nutrient elements such as nitrogen, phosphorus, potassium, organic matter and iron, manganese, copper；Protein and humic acid-state rich in
Amino acid.Many studies have shown that soil fertility, enhancing water retention property can be improved and increase plant life after peat applies aeolian sandy soil
Force of labor.But the quantity per capita of China's mud and charcoal be it is insufficient, in recent years, with the exhaustive exploitation to peat and to peat
The increase of consumption, leads to the rare of mud and charcoal, and China becomes peat importer from original simple peat exported country.2.
In recent years, more and more in research of the high-molecular organic material on aeolian sandy soil modifying, organic polymer can by physics or
Chemical action is incorporated on dust storm soil particle, so that fine dust storm soil particle is interconnected by these macromolecular chains, can be mentioned
The water holding capacity of high soil promotes plant growth.The concentration class and seepage of water of soil can be improved in polyacrylamide, prevents water and soil
It is lost.In US West, 20Rhm has been generalized to as soil conditioner using polyacrylamide2, polyacrylamide is a kind of high
The soil stabilizer of effect, the main problem for influencing its application is that price is too high, is not suitable for large-area applications.Meanwhile sewage treatment
Factory can generate a large amount of by-product during handling sewage --- and sludge, sludge contain a large amount of sex pheromones and organic nothing
Machine pollutant has foul odour.Also, China's sludge yield sharply increases, and if do not dealt carefully with, is easy to bring dirt to environment
Dye, endangers human health.On the other hand, how the nutrients such as sludge organic matter rich in, nitrogen, phosphorus, potassium and microelement, make
Beneficiating ingredient in sludge is used, and reaches sludge reduction, innoxious and recycling target, is one urgently to be resolved
The problem of.
In order to improve the above problem, Chinese Patent Application No. provides a kind of new dust storm land reform for CN201110039583.5
Good dose, with the aeolian sandy soil after method improvement of the invention, mechanical composition is improved, and soil clay particle content increases, and organic matter contains
Amount significantly improves, and the nutrient contents such as N, P, K significantly improve, and the soil weight is reduced, and porosity increases, and soil water storage is also
It improves.The advantageous effect of the invention includes after applying sludge, and Water and fertilizer retention ability of soil improves, and is conducive to plant growth, thus
Fixing soil reduces wind erosion, improves soil property.
The reclamation result of existing soil conditioner is poor, and water-stable aggregate content is few, erosion durability of soil energy
Difference causes soil texture stability poor, is easy to happen soil erosion.
Summary of the invention
