Abstract
The invention relates to a microelement fertilizer for agricultural use. The microelement fertilizer is calcium hydrogen phosphate suspending agent which is sticky with high concentration. The compositions by mass percent of the microelement fertilizer are: 20 to 80 percent of raw calcium hydrogen phosphate powder, 1 to 7 percent of wetting agent, 2 to 10 percent of dispersant, 2 to 6 percent of antifreeze, 0.2 to 1.0 percent of defoaming agent, 0.1 to 0.8 percent of thickening agent, and 2.2 to 76.7 percent of water. The compositions are mixed evenly with high shear and are grinded to the fineness between 0.5 and 6 micron; the viscosity coefficient of the mixture is adjusted by the thickening agent to obtain the calcium hydrogen phosphate suspending agent. The microelement fertilizer is prepared through adopting the high-performance addition agent and advanced technology. The microelement fertilizer is characterized by high content of activity components, good dispersion performance and stable heat storing performance. In the application, the microelement fertilizer has the advantages of rapid calcium supplement speed, good effect, small dosage of the fertilizer and environmental protection.
Description
Technical field
This invention relates to a kind of agricultural trace element fertilizer, relates to secondary calcium phosphate suspension agent and composition thereof.
Technical background
In China's agricultural production, need to use multiple agricultural fertilizer.Wherein nitrogen, phosphorus, potassium are the maximum elements of crop demand, are called macroelement; Boron (B), manganese (Mn), zinc (Zn), copper (Cu), molybdenum (Mo), iron (Fe), chlorine (Cl) element crop requirement are little, are called trace element; Calcium (Ca), magnesium (Mg), sulphur (S) element requirement claim moderate-element between the centre.In the process of China's agriculture production, macroelement is by being replenished crop at a large amount of chemically composited fertilizer of soil application; Trace element also obtains peasant's attention, by application of organic fertilizers material or blade spraying trace element recombiner crop is replenished; Secondary nutrients has limited the further raising of crop yield and quality because wrong on the understanding or think little of lacks available moderate-element in the soil (mainly referring to calcium and magnesium).Wherein calcium deficiency to the plant growth influence obviously.The intravital calcium of plant has multiple function, as the regulatory function to biological membrane permeability.Calcium is also relevant with the formation of cell walls, owing to the middle lamella of cell walls is made up of Pectin calcium, so calcium is a kind of very important element that constitutes cell walls.During calcium deficiency, the formation of cell walls is hindered, and influences cell fission, or cell fission is incomplete, can not form new cell walls, syncyte can occur, so meristematic tissue is injured the earliest.Therefore during calcium deficiency, cell fission and growth all are suppressed, the tender organ of children (tip of a root, the stem end) necrosis (withered worry) of festering when serious.Calcium has certain effect to plant disease-resistant in addition, if the plant calcic is more abundant, then easily forms callus.
In present stage, China's plant husbandry is replenished the calcium based on lime, gypsum to fruit and vegetables, also uses phosphate fertilizer or the additional calcium of nitrogenous fertilizer such as fused(calcium magnesium)phosphate, calcium superphosphate, nitrocalcite simultaneously.Application process adopts the mode of soil application to use more.The soil application method is used when being applicable to the prevention calcium deficiency owing to absorbing slowly, absorbing incomplete reason.Too much can reduce the validity of micronutrient elements such as boron, zinc and cause soil compaction but use.When peasant household found the fruit tree and vegetable calcium deficiency, calcium deficiency had often arrived more serious degree, at this moment only carries out foliage applying and could effectively control the crop calcium deficiency.Foliage-spray nitrocalcite, calcium chloride can be replenished the calcium rapidly, but nitrocalcite, calcium chloride belong to acid inorganic chemical, and the active calcium ion content is low, and consumption is big, very easily produce the fertilizer evil.Therefore, need to seek more efficient, absorb fast, safety, and be applicable to the fertilizer agent of replenishing the calcium of crop Foliage Absorption.
Secondary calcium phosphate is a kind of Chemicals commonly used, is used for feedstuff industry, food service industry more.Secondary calcium phosphate is a kind of powdery solid, and the calcium content height also can replenish phosphorus simultaneously.But directly use, crop leaf is difficult for absorbing.It is crucial that secondary calcium phosphate is mixed with appropriate formulation.At present, prepare and use still unmanned report at the preparation of China's secondary calcium phosphate suspension agent.
Summary of the invention
Purpose of the present invention is exactly slowly, easily to produce environmental pollution or be difficult for shortcoming such as absorptions and a kind of high-content, environment-friendly type, the easy high secondary calcium phosphate suspension agent of absorption rate developed in order to overcome existing fruit tree and the vegetables technology medium velocity of replenishing the calcium.Suspension agent is the Water-borne modification formulation, has the low characteristics of environmental protection and cost concurrently, is a megatrend of present agricultural fertilizer formulations processing development.
The objective of the invention is to realize that by following technical scheme the effective ingredient of secondary calcium phosphate suspension agent is a secondary calcium phosphate, it is characterized in that said preparation is the sticky shape white liquid of high density.Its component content is by percentage to the quality:
The former powder of secondary calcium phosphate: 20%-80%
