Technical Field
The invention relates to the technical field of fertilizers, in particular to an agricultural compound fertilizer and a preparation method thereof.
Background
In modern agricultural production, fertilizers have been used to a maximum extent in order to increase the yield of crops. At first, a single kind of fertilizer, such as urea, ammonium bicarbonate, ammonium nitrate, diammonium phosphate and the like, is used, and with the progress of technology, researches show that elements needed by crops in a growth cycle are diverse, elements needed by different species or different lands are different, and the effective period of the single kind of fertilizer is short, so that in use, the fertilizer is used as a base fertilizer and also needs to meet the growth needs of agricultural action through additional fertilization, which leads to the increase of the cost of agricultural production.
In order to adapt to the needs of different species or different lands and reduce the cost of agricultural production, compound fertilizer technology is developed, and the fertilizers in the current agricultural production are basically replaced by the compound fertilizers, mainly because the compound fertilizers comprise multiple elements which can provide the elements needed in the growth period for different species to the maximum extent possible.
However, the effective period of the compound fertilizer used at present is greatly improved compared with that of a single-element fertilizer, but the compound fertilizer still cannot be matched with the growth period of crops. And after the fertilizer is decomposed in a short time, crops cannot be fully and effectively utilized, redundant parts can form gas or run off along with rainwater after being decomposed under the action of various enzymes in the land and rainwater, a large amount of waste is caused, and meanwhile, the atmosphere and water sources are greatly polluted.
