Description
Technical field
The present invention relates to slow release fertilizer technical field, particularly relate to a kind of slow release water-holding compound fertilizer material fertilizer and preparation method thereof.
Background technology
At present, China market agricultural fertilizer material, substantially there are three kinds: a kind of fertile for industrial chemicals, one is fertilizer, also having one is industrial chemicals and organic fertilizer mixing fertilizer
；The shortcoming of industrial chemicals: life-time service can cause soil soil property to harden, and affects plant growth, causes the progressively underproduction；The shortcoming of organic fertilizer is: needed for plant, nutrient is not enough, can not meet the demand of production estimation；Affect crop yield；The shortcoming that mixing is fertile: organic matter and full nutrient in fertilizer formula are conflicting, this is high, and that are low, such as organic too high levels, produce granule difficulty.Additionally; China's Arid&semi-arid area gross area accounts for the 50% of territory total area; China's agricultural is again to use water rich and influential family; Water Consumption in Agriculture exceedes the 70% of total water consumption; and production efficiency is the lowest; China's annual agricultural water breach is about at 30,000,000,000 m 3, and agricultural water crisis presents and constantly aggravates situation.Water-loss reducer of soil is used alone not only increases work number of times and cost, and because water-loss reducer of soil consumption is the most less, it is difficult to be fully contacted with fertilizer so that received moisture is difficult to and nutritional labeling generation reciprocal action, largely reduces effect of water-retaining agent.Additionally, the common fertilizer water solublity used at present is the highest, rate of release is very fast, and the release phase is shorter, and uses totally basal dressing techniques more, make fertilizer nutrient rate of release poor with crop regulation of fertilizer requirement synchronicity, fertilizer nutrient loss is very big, and fertilizer nutrient utilization is relatively low, though and split application method can improve crop different growing nutrient demand, but time-consuming, it is not suitable with the requirement of modern agriculture high-efficient development.And, the fertilizer efficiency height in being manured into soil is in close relations with soil water regime, and " with fertile water transfer, promoting fertilizer with water " is highly important rich water control technique in agricultural production.
Mulch film has the effects such as insulation, water conservation, frost protection to crop, the application of ground membrane technology improves and yield and the benefit adding crops greatly, but tradition mulch film is the macromolecular compound of a kind of synthetic, degradable the most hardly, after using, place to go is not comprehended soil environment is caused the biggest pollution, affects crop root growth, and the mulch film processed is because of moist, damaged, the most not reusable edible, only as garbage reclamation, work consuming is time-consuming.
Therefore, being modified fertilizer, improving fertilizer efficiency is to reduce fertilizer use, the effective way increased operation rate.Slow-release or control-release fertilizer is exactly one of effective measures improving chemical fertilizer utilization ratio such as at present, slow-release or control-release fertilizer can efficiently control the release of nutrient, extend fertilizer efficiency period, meets utilization rate that the whole period of duration of crop to the needs of fertilizer nutrient, can improve fertilizer to greatest extent, reduces the wasting of resources and environmental pollution, to promoting agriculture and forestry volume increase, increasing peasant income, agriculture and forestry sustainable development important role, it it is the important development direction of 21 century fertilizer industry.
Summary of the invention
