Description
Technical field
The present invention relates to a kind of Multiple-effect super absorbent resin fertilizer and preparation method thereof, agricultural, afforestation, urban landscaping, sandy land improvement and environmental improvement engineering, soil improvement engineering can be widely used in.
Background technology
China is the country of a serious water shortage, and urban population drinking-water is in existing more than 800 of the city of serious water shortage, in agriculture, the abnormal shortage of forestry water resources, particularly the Northwest, especially serious water shortage, Desertification is serious year by year, natural environment deterioration, dry, Dry land, underground water is day by day exhausted, rainfall amount reduces year by year, and soil water evaporation quantity strengthens year by year, and utilization rate of fertilizer reduces year by year, soil worsens, and irrigation cost strengthens year by year.Agroforestry are produced and are faced a severe test, the practical situation of comprehensive China, especially a kind of novel resisting drought saving water technology is needed, particularly in the midwestern arid area of China, the current saving water, resisting drought technology of China is as sprinkling irrigation, drip irrigation builds the large construction projects such as water channel, also have and adopt plastic sheeting for farm use to cover, collect the peasant household such as rainwater to have the ability unaided project, but above various water-saving technology in application more or less have certain drawback, Engineering Project is large, be difficult to realize as there is no the support of substantial contribution strength and government, simultaneously, also the waste that the loss of water causes is had, plastic sheeting for farm use water saving short period of time in crop growth period is used to play water-saving result, but on using, relate to the process problem in later stage, and there is pollution problem, so domestic agroforestry need of production uses the New Technique of Save on Water in Steam Electric of novel practical.
At present, the fertilizer that domestic farm crop use is substantially with mineral manure, the chemical fertilizer such as organic-inorganic compound fertilizer are main, and the application of humic acids and microbial fertilizer is not also widely used, moreover above each seed manure is all to use separately, fail to accomplish that the combination of available nutrient is collaborative to use, do not reach the optimization of result of use, a large amount of accumulation used continuously for many years in soil of mineral manure, cause a large amount of salinity to be retained in soil, make soil deterioration, occur hardening, active reduction, fertilizer efficiency utilization ratio reduces.Above each fertilizer all exists and does not possess water-absorbing-retaining drought resisting function in addition, the solution absorption of mineral manure, the activation of humic acids, the growth and breeding of microorganism fertilizer bacterial strain, all none be unable to do without a moistening stable environment, there is the abundant utilization absorbed by crops of the various available nutrient ability of moist environment, crop is in the state of a liquid manure nutritive equilibrium within whole vegetative period always.
In addition, though the agricultural high-absorbent resin of domestic use has certain soaking effect, but the rear polymer colloid of water suction is ventilative, bad hydraulic permeability, with soil granular in conjunction with poor, see photolysis, life cycle is short, is used alone because it is granular and consumption skewness in soil in addition, fall flat, be difficult to widely use.
