Abstract

The invention discloses an ammonium potassium phosphate composite water-soluble fertilizer which is prepared from the following components in parts by weight: 5-30 parts of nitrogen source, 10-20 parts of phosphorus source, 10-50 parts of potassium source and 4-20 parts of microelement mixture. The microelement mixture comprises nutrients of a sulfur source, a boron source, a zinc source and an iron source. The prepared fertilizer has the advantages of favorable solubility, high solution rate and no impurity, and is suitable for various trickle irrigation plants. According to the invention, the fertilizer can be properly and directly applied to the root system centralized layer in proper time, and is applied slightly and frequently, so that the fertilizer application is regular and positioned; and thus, the fertilizer can be conveniently absorbed by crops, thereby reducing the crop loss, fully displaying the fertilizer efficiency, improving the soil and obviously increasing the yield.

Description

technical field [0001] The invention relates to a compound fertilizer, in particular to a potassium ammonium phosphate compound water-soluble fertilizer, which belongs to the technical field of chemical industry. Background technique [0002] The advent of chemical fertilizers increased the yield of agricultural products. The main components of chemical fertilizers include nitrogen, phosphorus and potassium. [0003] Long-term use of this traditional chemical fertilizer has simple nutrients and poor crop growth. Soil absorbency is poor. In addition, the local environment of the soil becomes worse, the fertility decreases, and the soil compacts. The main disadvantages are also manifested as the reduction of available nutrients and the reduction of nitrogen fertilizer absorption. The fixation rate of phosphorus in the soil increases, and the utilization rate of phosphorus decreases. In addition, the drought resistance, heat resistance, and disease resistance of crops have...
