Description
Technical field
The present invention relates to technical field of fertilizer, more particularly to a kind of liquid silicon fertilizer its production method.
Background technology
Siliceous fertilizer is a kind of new-type fertilizer, and the fourth-largest fertilizer unit after nitrogen, phosphorus, potassium element is classified as by international soil circle
Element, is mainly used in the happiness silicon crop such as paddy rice, wheat, corn, sugarcane.Wherein paddy rice have the title of silicic plant, and Applying silicon fertilizer can
With the accumulation for strengthening paddy disease-resistant ability, drought-resistant ability, neck hardness, photosynthesis, setting percentage and promoting dry, Jin Erzeng
Plus yield.According to the literature：After Applying silicon fertilizer, increasing production of rice 10%~20%, wheat increase yield 10%~15%, peanut yield increasing 15%~
35%, soybean yield-increasing 10%~20%, sugarcane production-increasing 10%~25%, corn yield increasing 12%~20%, vegetable increase production 12%~20% is economical
Benefit is considerable.
Although the content of silica accounts for the 50%~70% of soil weight in soil, the overwhelming majority is in crystalline state, no
Can be absorbed and used by plants.In recent years, as a large amount of of the chemical fertilizer such as nitrogen, phosphorus, potassium use, the effective silicon in soil and irrigation water contains
Amount declines year by year, causes some areas crop production reduction, and the scarce silicon area in country arable land is even more and has reached 50%, so applying siliceous fertilizer
Into volume increase important channel.But existing siliceous fertilizer its absorptivity, stability, fertilizer efficiency can not all meet market demands.Chinese invention is special
Sharp specification discloses a granted patent " one kind is containing silicon foliage fertilizer and preparation method thereof ", Patent No. " ZL98121697.8 "
