Abstract

The invention discloses a water-soluble macroelement liquid fertilizer. The water-soluble macroelement liquid fertilizer comprises components in parts by weight as follows: 20.0-25.0 parts of urea, 18.0-25.0 parts of monopotassium phosphate, 5.0-10.0 parts of potassium chloride, 25.0-35.0 parts of potassium nitrate, 0.6-0.75 parts of a dispersing agent, 0.6-0.75 parts of a surfactant, 0.3-0.45 parts of a suspending agent, 0.2-0.45 parts of a thickening agent and 15-20 parts of water. According to the water-soluble macroelement liquid fertilizer, the problem of stability of macroelements in a water system is solved, the fertilizer is long-acting, uniform, stable and applicable to various fertilizer application methods such as drip irrigation, sprinkling irrigation, foliage spraying and the like, both the water and the fertilizer are saved, and the absorption and utilization efficiency of the fertilizer is greatly improved.

Description

technical field [0001] The invention relates to the field of agricultural chemical fertilizers, in particular to a water-soluble fertilizer for macroelements in a full water solution. Background technique [0002] Water-soluble fertilizer with large amounts of elements is a water-soluble compound fertilizer that contains a large amount of nitrogen, phosphorus, and potassium and can be completely dissolved in water. It is a liquid or solid product that is dissolved or diluted in water and can be used for fertigation (including sprinkler irrigation, drip irrigation, etc.), foliar fertilization, soilless cultivation, soaking seeds and dipping roots, etc. The use of water-soluble fertilizers with a large number of elements not only saves water, but also saves fertilization, and the plants absorb quickly, the absorption utilization rate is high, the nutrition is comprehensive, and the effect is quick. [0003] The research on liquid fertilizers started relatively late in my coun...
