The source of silicon in this type of fertilizer is mainly sodium silicate, and excessive sodium ions are harmful to soil and crops; nitrogen, phosphorus, potassium and silicon quaternary fertilizer and its preparation method (publication number CN101805219A) disclose a combination of silicon and potassium fertilizer, urea , potassium chloride, monoammonium phosphate, ammonium chloride, synthetic chlorine and sulfuric acid to produce nitrogen, phosphorus, potassium and silicon quaternary fertilizers. Due to the selection of too many materials, the PH value is unstable, and it is easy to cause the precipitation of some insoluble substances, and the content of active ingredients is low. , packaging, storage, and transportation costs are high

Abstract
The invention relates to a silicon-containing water-soluble fertilizer. The silicon-containing water-soluble fertilizer is characterized by comprising four main nutrient elements N, P, K and Si, wherein the four main nutrient elements N, P, K and Si are supplied by three substances including water-soluble silicate, poly-condensed potassium phosphate and ammonium polyphosphate. The silicon-containing water-soluble fertilizer can be produced into a solid fertilizer or a liquid fertilizer. The fertilizer with high content of effective elements has a function of obviously increasing the yield, the quality and the stress resistance of plants, and is applicable to food crops, vegetables, fruit trees and the like.
Description
technical field [0001] The invention relates to a silicon-containing water-soluble fertilizer. Background technique [0002] For a long time, people have believed that 16 elements such as nitrogen, phosphorus, potassium, carbon, hydrogen, oxygen, calcium, magnesium, copper, iron, zinc, boron, molybdenum, sulfur, and chlorine are essential elements for crop growth. In fact, in addition to the 16 nutrients mentioned above, plants absorb more silicon than nitrogen. Silicon plays an important role in building cell walls and forming epidermal tissues in plants. [0003] As early as 1926, agricultural researchers at the University of California in the United States began to study silicon fertilizers and affirmed the fertilizer efficiency of silicon. In 1935, Japan started the research on silicon fertilizer, and in 1954, it began to produce and apply it. In 1957, the Japan Silicon Fertilizer Association was established. In 1955, the Japanese government identified silicon fertiliz...
