Abstract
The present invention relates to a compound fertilizer and a preparation method thereof. The compound fertilizer comprises calcium superphosphate, potassium magnesium fertilizer, plant ash, ammonium bicarbonate, urea and a straw fermentation product. The compound fertilizer is prepared into two granular fertilizers, namely 100 parts of a compound fertilizer A and 100 parts of a compound fertilizer B. The 100 parts of the compound fertilizer A comprise 8-10 parts of calcium superphosphate, 2-3 parts of potassium magnesium fertilizer, 4-5 parts of plant ash and the straw fermentation product as the remainder. The 100 parts of the compound fertilizer B comprise 5-8 parts of ammonium bicarbonate, 3-5 parts of urea and the straw fermentation product as the remainder. The compound fertilizer A and the compound fertilizer B are both granular, wherein each of the two compound fertilizers is composed of an inner layer and an outer layer. The outer layers of the two compound fertilizers are prepared by the straw fermentation product, while the inner layers of the two compound fertilizers are prepared by calcium superphosphate, potassium magnesium fertilizer, plant ash, ammonium bicarbonate or urea. The compound fertilizer of the present invention can avoid the loss of fertilizer nutrients along with the irrigation. Furthermore, plantation nutrients are maintained, while the contamination of the downstream water quality is avoided at the same time.
