Description
Technical field
The utility model relates to agricultural fertilizer and delays, releases control carrier, the particularly slow-release fertilizer dedicated particle of a kind of flowers.
Background technology
For a long time, at China's agriculture field, long-term existence and is used the low problem of straight fertilizer, a fertilizer and fertilizer nutrient utilization, according to the literature, the this season utilization ratio of nitrogenous fertilizer is about 30%-40%, the this season utilization ratio of phosphate fertilizer is 10%-25%, and the utilization ratio of potash fertilizer is 50%-60%, traces it to its cause, be the water-soluble height of common fertilizer, nutrients release block, release period is shorter, causes fertilizer nutrient release period, releasing degree and crop not to match caused to the absorption phase of nutrient and demand.
In recent years, domesticly have employed that number of mechanisms water-solublely to be delayed common fertilizer, controlled release controls, fertilizer product and poly-winter propylhomoserin resin are organically combined, using poly-winter propylhomoserin resin as the carrier delaying, release the release of control fertilizer nutrient, to the release of fertilizer nutrient effectively can be delayed, make the release period of fertilizer nutrient, burst size and crop substantially identical to the absorption phase of nutrient, demand, improve the utilization ratio of fertilizer nutrient, improve the usefulness such as soil moisture content, water-retentivity, reduce production cost, improve the earning rate of farm crop.
Poly-winter propylhomoserin resin, as one water suction, water-holding agent, is administered in soil and not only fully can absorbs irrigation water or natural precipitation water, prevent Water deep leaching and loss, improve the utilization ratio of water, and the formation of soil agreegate can be promoted, improve Pore structure in soil, prevent erosion.Therefore, poly-winter propylhomoserin resin is widely used in agricultural, field of forestry.But, soil water content and validity thereof are also depended in the performance of fertilizer efficiency, interaction is there is between water, fertilizer, therefore, research and development have the delaying of water retaining function, release the production practical problemss that control fertilizer is the urgent solution of needs, therefore, the research about poly-winter propylhomoserin resin fertilizer comes into one's own day by day.
Summary of the invention
The purpose of this utility model is to provide the slow-release fertilizer dedicated particle of a kind of flowers, to the release of fertilizer nutrient effectively can be delayed, make the release period of fertilizer nutrient, burst size and crop substantially identical to the absorption phase of nutrient, demand, improve the utilization ratio of fertilizer nutrient.
In order to realize above-mentioned target, the technical solution adopted in the utility model is: the slow-release fertilizer dedicated particle of a kind of flowers, comprise shell, middle layer and stratum nucleare, middle layer is combined with outside the stratum nucleare of described slow release fertilizer particle, shell is combined with outside middle layer, described stratum nucleare is for regulating oxidant layer, and described adjustment oxidant layer preferentially adopts and in the three-dimensional structure network of water-absorbing resin matrix, is combined with plant modifying agent and the adjustment oxidant layer that forms; Described middle layer composite fertilizer active layer, composite fertilizer's active layer that described composite fertilizer active layer preferentially adopts kilnitamin chelating medium trace element in humic acid soil matrix matter and forms; Described shell is slowly-releasing control layer, the slowly-releasing control layer that described slowly-releasing control layer preferentially adopts poly-winter propylhomoserin layer to form.
Described absorbent resin matrix is the superpolymer with three-dimensional net structure, and its water-retaining capacity can reach the hundred times even several thousand times of own wt, comprises the superpolymer such as sodium polyacrylate, polyvinyl alcohol.
Described plant modifying agent adopts the composition of Plant hormones regulators,gibberellins, Nafusaku.
Described chelating amino acids medium trace element adopts complex amino acid aqueous solution 50-60 part, moderate-element compound 30-40 part, and trace element 10 parts forms through chelating technique.Wherein, complex amino acid aqueous solution Determination of Free Amino Acids is >=29%, and the kind of described aminoacids complex is the composition of aspartic acid, Threonine, Serine, L-glutamic acid, glycine, propylhomoserin, phenylalanine, Methionin, arginine, Histidine, methionine(Met); Described moderate-element compound is the composition of calcium chloride, magnesium chloride, anhydrous magnesium sulfate, ammonium sulfate; Described trace element is the composition of boric acid, zinc sulfate, copper sulfate, ferrous sulfate, four water ammonium molybdates, manganous sulfate.
In described aminoacid chelating microelement solution, also can add and comprise nitrogen, phosphorus (P
2o
5), the basic fertilizer of potassium.
The beneficial effect that the utility model realizes: the release that effectively can delay fertilizer nutrient, make the release period of fertilizer nutrient, burst size and crop substantially identical to the absorption phase of nutrient, demand, improve the utilization ratio of fertilizer nutrient, improve the usefulness such as soil moisture content, water-retentivity, reduce production cost, improve the earning rate of flower crop, there is huge economic benefit, social benefit and environmental benefit, for developing water-saving planting and improving the ecological environment, tool is of great significance.
Accompanying drawing explanation
Fig. 1 is the structural representation of the slow-release fertilizer dedicated particle of a kind of flowers.
In figure, 1 is stratum nucleare, and 2 is middle layers, and 3 is shells.
Embodiment
Crop is because metallo-chelate quite stable to the reason that metallo-chelate especially easily absorbs.After in polydentate ligand, certain ligating atom is combined with central metal atom, the distance of remaining ligating atom and central atom reduces, and the probability that they are combined with central atom just increases.If wherein there is a coordinate bond to destroy, because other ligating atoms in polydentate ligand still with central atom bonding, the coordination be destroyed is good for more easily recover, the more, in part, available ligating atom just the more for the ligating atom in polydentate ligand, form chela ring just the more, the coordination that same part and central atom are formed is strong just the more, and the chance of part off center atom is just less, and inner complex is just more stable, therefore, crop especially easily absorbs metallo-chelate.
In sum, containing amino acid whose water-soluble fertilizer, utilize chelating amino acids plant nutrient, make inorganic elements become organic chelated state element, the absorption rate of nutritive element is improved further, show as with strong points, fertilizer efficiency is fast, and consumption is few, save manpower, increase yield significantly, and soil can be avoided the fixed action of some nutrient, economical and efficient.
Embodiment 1
Further understanding to do the utility model, now by reference to the accompanying drawings it being explained.
As shown in Figure 1, the slow-release fertilizer dedicated particle of a kind of flowers of the present utility model, comprise shell 3, middle layer 2 and stratum nucleare 1, middle layer 2 is combined with outside the stratum nucleare 1 of described slow release fertilizer particle, shell 3 is combined with outside middle layer 2, described stratum nucleare 1 is for regulating oxidant layer, and described adjustment oxidant layer preferentially adopts and in the three-dimensional structure network of water-absorbing resin matrix, is combined with plant modifying agent and the adjustment oxidant layer that forms; Described middle layer 2 composite fertilizer active layer, composite fertilizer's active layer that described composite fertilizer active layer preferentially adopts kilnitamin chelating medium trace element in humic acid soil matrix matter and forms; Described shell 3 is slowly-releasing control layer, the slowly-releasing control layer that described slowly-releasing control layer preferentially adopts poly-winter propylhomoserin layer to form.
