Description
Technical field
The present invention relates to field of crop production, especially a kind of water-loss reducer of soil and preparation method thereof.
Background technique
As changing the one kind for controlling water-saving material, water-loss reducer of soil is also known as super absorbent resin, it is intermolecular for cross-linked polymeric and
At reticular structure, containing very strong hydrophilic radical, it can absorb rapidly ten times, hundred times of sole mass by aquation
Even thousand times of moisture forms gel, and can absorb water repeatedly.Water-retaining agent can stable soil structure, reduce the soil weight,
Soil capillary moisture capacity is improved, moisturizes and infiltrates, the evaporation of soil moisture control reduces drought stress, promotes plant growth
Development.Synthetic resin, starch and cellulose family can be divided by raw material sources.The raw material sources of starch water-retaining agent are abundant,
Product water absorbent rate is high, but gel strength is low after absorbing water, long-term poor water retention property, in use vulnerable to microorganism decompositions such as bacteriums and
Lose water suction, water retention.Cellulose water retention agent water absorbent rate is lower, at the same also be easy by the decomposition of bacterium lose water suction,
The ability of water conservation.Currently, the main product of water-retaining agent is synthetic resin, with polyacrylate, hydrolysate polyacrylonitrile, vinegar
Based on vinyl acetate copolymer, modified poly ethylene alcohols, the most water-retaining agent water conservation duration are too short, can absorb water on surface but when
Between the long ability for just losing water suction and discharging water, cause to easily corrode plant root in soil moisture, in drought condition
Under easily cause soil hardening.In addition, the function of the water-retaining agent of the prior art is mainly retained, the work of nutrition is not had to farmland
With this is also one of its drawback.
