| titleOfInvention | A kind of charcoal base slow-release nitrogen fertilizer and preparation method thereof |
| abstract | The present invention relates to a kind of charcoal base slow-release nitrogen fertilizer and preparation method thereof, the charcoal base slow-release nitrogen fertilizer is made up of the component of following mass fraction：45 parts 55 parts of charcoal, 45 parts 55 parts of nitrogenous fertilizer.The preparation method comprises the following steps：Pulverization process is carried out to charcoal and nitrogenous fertilizer, and be well mixed the charcoal and nitrogenous fertilizer after pulverization process, it is heated to nitrogenous fertilizer fusing, and the nitrogenous fertilizer of the fusing is entered in the loose structure of charcoal under elevated pressure, granulation can obtain charcoal base slow-release nitrogen fertilizer after well mixed, wherein, the pressure of the pressurization is 0.1Mpa 0.15Mpa.Preparation method of the invention can make in the loose structure that fertilizer enters charcoal, with had good sustained release effect, slow-release time advantage long, simultaneously, realize recycling waste, avoid the pollution that coated fertilizer is produced to soil, can be applied to field crop, facilities vegetable, fruit tree etc. fertilising in, with good upgrading synergistic effect. |
