Description
Technical field
The present invention relates to siliceous fertilizer technical field, particularly relate to a kind of water conservation and loosen the soil controlled release siliceous fertilizer and preparation method thereof.
Background technology
Siliceous fertilizer is a kind of new-type fertilizer, is classified as the fourth-largest fertilizer unit after nitrogen, phosphorus, potassium element by international soil circle
Element.It is mainly used in the happiness silicon crops such as Oryza sativa L., Semen Tritici aestivi, Semen Maydis, Caulis Sacchari sinensis.Wherein Oryza sativa L. have the title of silicic plant, and Applying silicon fertilizer can
To strengthen paddy disease-resistant ability, drought-resistant ability, cervical region hardness, photosynthesis, setting percentage and the accumulation of promotion dry, Jin Erzeng
Add 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%, economical
Benefit is considerable.
Although, in soil, the content of silicon dioxide accounts for the 50%～70% of soil weight, but the overwhelming majority is crystalline state, no
Can be absorbed and used by plants.In recent years, along with a large amount of uses of the chemical fertilizer such as nitrogen, phosphorus, potassium, the effective silicon in soil and irrigation water contains
Amount declines year by year, causes some areas crop production reduction, domestic arable land to lack silicon area and has reached 50% especially.
Domestic siliceous fertilizer kind currently mainly has: blast furnace slag type siliceous fertilizer, silico-calcium magnesium types siliceous fertilizer, diatom soil type siliceous fertilizer etc..High
The granule solubility in citric acid siliceous fertilizer that slag type siliceous fertilizer simply processes mainly by the waste residue smelted iron or make steel, main component
It is calcium magnesium silicate ferro-aluminum etc., easily with substantial amounts of heavy metal (arsenic, cadmium, lead, chromium etc.) inside this waste residue, easily causes secondary
Heavy metal pollution；Cadmium pollution the most in all parts of the country and lead contamination are day by day serious, so the Ministry of Agriculture was the most also sent out before handle
The registration card of the slag type siliceous fertilizer put is being regained.Silico-calcium magnesium types siliceous fertilizer, diatom soil type siliceous fertilizer are all solubility in citric acid siliceous fertilizers, need a large amount of
Using, and belong to resource-type siliceous fertilizer, the heavy metal component/content of the inside is uncontrollable, also easily causes secondary heavy metal pollution,
