Abstract
A kind of water solubility iron fertilizer and preparation method thereof, ingredient is made by ferrous sulfate, urea and stabilizer are reacted in water, is a kind of water soluble fertilizer of supply plant divalent iron ion.Preparation method be in the reaction kettle with heating agitating device, using water as medium, under room temperature or heating, stirring condition, using ferrous sulfate as source of iron, with urea and stabilizer are reacted is made.The mode to plant leaf surface sprinkling, trickle irrigation root application can be used, ferro element is supplemented for plant.The present invention solve be dissolved in by source of iron of ferrous sulfate water using when, oxidizable divalent iron ion be trivalent iron ion, the problem of to lose fertilizer efficiency, cannot be absorbed and used by plants, have the advantages that using effect is good, price is low, it is simple for process, energy consumption less, without discharge.
Description
[Technical field]
The present invention set and it is a kind of spray suitable for plant leaf surface, fertigation, the water soluble fertilizer for supplying plant ferro element
And preparation method thereof.
[Background technology]
Iron is to plant to grow one of necessary nutrient, and synthesis, breathing and the redox that it participates in plant chlorophyll are anti-
Physiology courses should be waited, after plant iron deficiency, yellow leaf loses photosynthesis, and fruit quality declines, and yield reduces, and is planted when serious
Strain is withered.
Although iron is widely present in soil, but seldom for the ferrous iron that plant absorption utilizes, especially in arid
On semiarid calacareous soil, iron deficiency phenomenon is more serious.In recent years, due to the substantial increase of fertilizer mu dosage, seriously
Absorption of the plant to ferro element is influenced, various regions crop iron chlorosis phenomenon is in the trend that is on the rise.
The effect that plant iron deficiency is solved using agronomy and biotechnology is not still fairly obvious, is still correction plant using iron fertilizer
The common effective ways of iron deficiency, the common iron fertilizer kind in the country are mainly ferrous sulfate and compound with ferrous sulfate and some organic matters
Iron fertilizer, but such iron fertilizer is dissolved in water or imposes on after soil that ferrous iron is oxidizable to lose fertilizer efficiency for ferric iron.All kinds of chelated irons
Again due to complex process, price is high, is difficult to degrade, some kinds such as NaFeEDTA can become persistent pollutant after degradation, difficult
In promoting the use of a large area.
The present invention has at low cost, safety non-pollution by the common material composition in several farmlands, can in water in soil
Keep ferrous iron not oxidized under low concentration, the effective source of iron of effective supply plant.
[Invention content]
The object of the present invention is to provide a kind of water-soluble iron fertilizers that can be utilized for plant efficient.
Have that preparation process is simple, technological process is short it is a further object to provide one kind, content is high, cost
It is low, the preparation method of water solubility iron fertilizer easy to use.
It is a kind of water solubility iron fertilizer be with weight percent be following material composition (being accurate to 2 significant digits number):
Water 17.86%~58.82%: urea 11.54%~52.63%: ferrous sulfate 11.54%~52.63%: stablize
Agent 3.22%~21.42%
A kind of preparation method of water solubility iron fertilizer is first to be added water and urea in the reaction kettle of band stirring heating, stirring shape
Under state, keep temperature in the kettle at 20 DEG C~60 DEG C.Stabilizer, ferrous sulfate are added after urea is completely dissolved, it is straight to continue stirring
It is completely dissolved as uniform liquid to material, is made after filtering.
