Abstract

The invention discloses a clear liquid type water-soluble fertilizer, which is prepared from the following raw materials by weight: 0.1-70 parts of a nitrogen source, 100-400 parts of phosphate, 300-400 parts of a potassium salt, 0.1-20 parts of a surfactant, 1-50 parts of a seaweed extraction liquid, 0.1-60 parts of an organic matter, 2-50 parts of trace elements, and 400-800 parts of water, wherein the nitrogen source is one or a plurality of materials selected from urea, a urea ammonium nitrate solution and a nitrogen solution, the phosphate is one or a plurality of materials selected from potassium dihydrogen phosphate, dipotassium hydrogen phosphate and ammonium polyphosphate, and the potassium salt is one or a plurality of materials selected from potassium dihydrogen phosphate, dipotassium hydrogen phosphate, potassium formate, potassium carbonate, potassium tripolyphosphate and potassium hydroxide. According to the present invention, the clear liquid type water-soluble fertilizer can solve the problem of low-temperature crystallization of the clear liquid type liquid fertilizer, is added with the organic matter and the seaweed extraction liquid so as to achieve long-lasting, uniform and stable effect, is suitable for drip irrigation, flush application, leaf spraying and other fertilizer application modes, and can improve the fertilizer utilization rate and save the cost.

Description

technical field [0001] The invention relates to the field of agricultural chemical fertilizers, in particular to a clear liquid type macroelement water-soluble fertilizer and a preparation method of the water-soluble fertilizer. Background technique [0002] With the rapid development of water-soluble fertilizers, large-scale mechanized planting management and fertilization of land, the state vigorously promotes the integration of water and fertilizer technology, and ordinary water-soluble fertilizers with a large number of elements can no longer meet the needs of planting. The emergence of concentrated liquid fertilizers solves the above problems, with less dosage, more concentrated ingredients, more convenient use, and a larger fertilization area, which is more in line with the future trend of agricultural development and market demand. [0003] Most of the existing concentrated liquid fertilizers are in the suspension form, which is a solid-liquid mixed state, such as Chi...
