Background technology
Chemical fertilizer claims again chemical fertilizer, is a kind of fertilizer that contains the required nutritive element of one or more plant-growths that utilizes chemistry, physics or biological method manually to make; It generally can include major element as carbon, hydrogen, oxygen, nitrogen, phosphorus, potassium, calcium, magnesium, sulphur etc., or middle trace element is as boron, copper, iron, manganese, molybdenum, zinc, chlorine etc.; It generally take the form of inorganics as main, organism as urea etc. be auxiliary.
Chemical fertilizer the most traditional and the most with the longest history is exactly people and animals' ight soil, and such chemical fertilizer does not generally need through the artificial course of processing again, and its raw material sources are compared with horn of plenty; Therefore but because above-mentioned traditional chemical fertilizer is a kind of material of indefinite form, and there is special smell, beginning stepping down from the stage of history gradually in modern plants plantation and proportion of crop planting.
Existing the most general chemical fertilizer is generally by the solid chemical fertilizer formulation of artificial or the particulate state of making by the method for direct chemosynthesis or powdery by natural mineral matter or animal body.The more traditional chemical fertilizer of chemical fertilizer solid dosage of particulate state or powdery has accessibility in the use really, and its special odor that does not have traditional fertilizer to have; Therefore, the solid chemical fertilizer formulation of the particulate state of manually making or powdery is subject to vast agricultural user's favor soon, and Bing China is being used by large-area.
But general employing of the method for application of granular chemical fertilizer solid dosage spread fertilizer over the fields or ditch spread, the general employing of application process of the chemical fertilizer solid dosage of powdery sprays or rushes and execute; Above-mentioned several method of application generally need to repeatedly be carried out during plant or plant growth, and the chemical fertilizer solid of particulate state or powdery is after entering soil water pouring, and because its this body structure of formulation is looser, it can be dissolved in rapidly in soil; Once the excessive use of user, chemical fertilizer will reach rapidly the highest concentration in soil, makes root system of plant cell compared with easy dehydration, cause burning the generation of seedling phenomenon, thereby causes plant to reduce the utilization ratio of chemical fertilizer, and chemical fertilizer waste is comparatively serious.
In addition, the chemical fertilizer solid of particulate state or powdery is often just reached the maximum value of its concentration after water pouring in soil, at this moment plant or crop are not good to its assimilation effect, once and run into rainwater weather, be dissolved in chemical fertilizer too much in soil and often can under the factor effects such as rainwater, run off and enter in the surrounding environment such as river or lake; Owing to being mostly the elements such as nitrogen, phosphorus, potassium in chemical fertilizer, these materials are exactly eutrophication on the comparatively serious impact in river or lake, cause water body matter to be damaged.The chemical fertilizer dissolving in soil just because the factors such as rainwater run off, causes the fertilizer efficiency period of chemical fertilizer shorter when not by plant or Crop, will make like this user increase the application times of chemical fertilizer, thereby form vicious cycle.
