Description
Technical field
The present invention relates to a kind of methods of soil water sorption water conservation.
Background technique
China is the serious country of drought and water shortage, and freshwater resources occupancy volume per person is only the 1/4 of world average level,
109 are ranked in the world, are poorest one of 13 countries of global per capita water resource.On the whole, north of China is partially dry
Drought is continuous always to the North China Plain from Xinjiang, this northern partially arid feature is obvious.Arid is drop in a long time
Water wretched insufficiency causes soil water deficit due to evaporation, destroys normal crop growth, thus studies water suction, water conservation
The good organic fertilizer of property is the inevitable requirement of current social sustainable development.
The effect of biological organic fertilizer contains two aspect of degradation white pollution and water conservation getting fat.On the one hand, biological organic fertilizer
In there is adhesive, three-dimensional net structure can be formed with the protective layer of some strength in the soil, can absorb more than itself weight
The moisture of hundred times is measured, while can control the speed of release, largely keeps moisture and fertilizer, improves plant survival rate.
On the other hand, the microorganism in biological organic fertilizer is absorbed, is aoxidized, restored and is degraded to white pollution object in soil, drop
Toxicity that is low or eliminating pollutant in soil achievees the purpose that control and improves soil environment.Bakass M etc. uses high water absorption
Resin water conservation, promotes the growth of plant, realization is fixed the sand.CN104788619 discloses a kind of star-like netted organic-inorganic compoiste
Super strength water absorbent and preparation method thereof can prepare super strength water absorbent under normal temperature state, have and stablize excellent water absorbing and retaining properties
Can, there is good salt tolerance, can be used for arid/semiarid zone defend and control sand, agricultural planting crops etc..
Super absorbent resin is a kind of containing strongly hydrophilics groups such as carboxyl, hydroxyls, and water-soluble with certain degree of cross linking
The high molecular polymer of swollen type, it is nontoxic, harmless, pollution-free, water, water suction, recycling can be released repeatedly.Environmentally friendly high score
Sub- polymer-based material is the research hotspot in current biological degradation field.This research is by starch and polyvinyl alcohol, acrylic acid-grafted
It is copolymerized and forms polymer binder, while be cross-linked to form special network structure on surface, and by organic matter, microorganism
Cladding in the network architecture, has excellent water suction and water holding capacity, and easily biological-degradable in the soil, is effectively improved soil ring
Border.
