Abstract
The invention belongs to the technical field of pesticide fertilizers, and particularly relates to a pesticide fertilizer/slow-release fertilizer combined multifunctional bactericidal slow-release pesticide fertilizer and a preparation method thereof. The pesticide fertilizer is composed of a bactericide which is one or combination of more of tebuconazole, hexaconazole and prochloraz, a nitrification inhibitor, a urease inhibitor, a phosphorus activator, urea formaldehyde and a compound fertilizer. The preparation method comprises the following steps: preparing part of bactericide, the nitrogen fertilizer synergist, phosphorus activator and compound fertilizer into a middle (more) product; and coating the urea formaldehyde and rest of bactericide on the middle (more) product as a coating material. The bactericidal slow-release pesticide fertilizer has the advantages of long acting time, slow release, high utilization ratio, long pesticide/fertilizer acting time, energy saving and environment friendliness.
Description
Technical field: the technical field that the invention belongs to medicine fertilizer, particularly relates to fertile multifunctional sterilization slow releasing medicinal fertilizer combined with slow-release fertilizer of a kind of medicine and preparation method thereof.
Background technology: fertilizer is the valuable cargo of agriculture production, occupies the weight of more than 30% in many Factor for increasing outputs.China is fertiliser production and uses big country, and output and usage quantity all occupy first place in the world.But the kind of fertilizer and quality aspect need further raising, especially also has certain gap with in multi-functional in utilization ratio compared with advanced country.
Agricultural chemicals effectively can prevent and treat the disease of crop, worm, crop smothering, in agriculture production, also play very important effect.Along with the development of agricultural science and technology, can moistureproof disease, worm, crop smothering, the Multifunctional pesticide fertilizer of crop full nutrition can be provided again, be subject to chemical fertilizer industry and agriculture common concern and favor.
Mostly current existing technology is agricultural chemicals and chemical fertilizer to make various medicine fertilizer by after certain formula rate mixing through granulation; its fertilizer efficiency and drug effect phase only have 30 ~ 50 days; and general farm crop breeding times was at 90 ~ 120 days; crop all needs fertilizer supply within whole breeding time; also need the whole process protection of agricultural chemicals, exempt from the harm of disease, worm, grass.Because of the fertilizer efficiency of existing common drug fertilizer and the drug effect phase short, aborning will repeatedly dispenser and topdressing, the utilization ratio again because of medicine fertilizer is low, only has 30 ~ 40%, and its large portion enters air and water body because of the leaching loss of volatilization, causes the serious wasting of resources and environmental pollution.
Summary of the invention:
Goal of the invention: in order to solve above-mentioned shortcoming and defect part of the prior art, the present invention proposes a kind of long-acting, slowly-releasing, utilization ratio are high, drug effect, fertilizer efficiency period length, energy-saving and environmental protection, sterilization slow releasing medicinal fertile and preparation method thereof.
Technical scheme: the present invention solves by the following technical programs:
A kind of sterilization slow releasing medicinal fertilizer is characterized in that product effective constituent proportioning by ratio of weight and the number of copies:
Nitrification inhibitor: 0.1 ~ 1.0%;
Urease inhibitor: 0.05 ~ 0.5%;
Phosphorus element activator: 0.05 ~ 0.5%;
Slow release fertilizer coated fertilizer: 0.1 ~ 1.0%;
Sterilant: 0.15 ~ 1.5%;
Composite fertilizer: 95.5 ~ 99.55%.
Described nitropyridine or dimethyl pyrazole phosphoric acid salt are nitrification inhibitor; Quinhydrones or thiophosphoryl triamide are urease inhibitor; Ammonium lignosulphonate or sodium lignosulfonate are phosphorus element activator; Urea formaldehyde is slow release fertilizer and coated fertilizer; Tebuconazole, own azoles alcohol or prochloraz one or more combination are sterilant; Composite fertilizer is composite fertilizer, the special fertilizer of the compositions such as nitrogenous fertilizer, phosphate fertilizer and potash fertilizer.
A kind of preparation method of sterilization slow releasing medicinal fertilizer is specific as follows:
First by above-mentioned raw material nitrification inhibitor, urease inhibitor, phosphorus element activator, 2/3 sterilant and composite fertilizer, through pulverizing, mixing, granulation makes centre (core) product, again urea formaldehyde and the dilution of 1/3 sterilant blending water are adopted coating process, urea formaldehyde and part sterilant are evenly wrapped on the particle of above-mentioned centre (core) product, finally make the fertile product innovation of a kind of sterilization slow releasing medicinal.
Advantage and effect:
1, adopt nitrification inhibitor, urease inhibitor, phosphorus element activator, urea formaldehyde, sterilant, carry out scientific compatibility, organically combine, make it produce synergy, play best effect.
2, its preparation method first the sterilant of nitrification inhibitor, urease inhibitor, phosphorus element activator 2/3 and composite fertilizer is made intermediates (core of coated fertilizer).Adopt coating process with urea formaldehyde and 1/3 sterilant, dilute with water again, it is evenly wrapped on above-mentioned centre (core) product.Make fertilizer reach synchronous with the release of sterilant and the demand of crop, make crop within whole breeding time, have sufficient fertilizer supply and the protection of agricultural chemicals.
3, fully extend fertilizer efficiency period and the drug effect phase of medicine fertilizer, improve utilization ratio, reach disposable employed medicine fertile, save labour, reduce costs, Asia can saving resource, reduce environmental pollution.
4, effectively can to prevent and treat multiple diseases in the time of infertility as Powdery Mildew, leaf spot, banded sclerotial blight, rice blast, rust, head blight etc., control rate improves 10%; Utilization rate of nitrogen fertilizer improves 20%, and P use efficiency improves 10%, agricultural produce 10%.
Embodiment:
Embodiment 1: get raw material: nitropyridine 0.3kg; Thiophosphoryl triamide 0.2kg; Ammonium lignosulphonate 0.15kg; Urea formaldehyde (UF) 0.2kg; Tebuconazole 0.45kg; Composite fertilizer 98.7kg.
Preparation method: by above-mentioned weight by nitropyridine, thiophosphoryl triamide, ammonium lignosulphonate, 2/3 tebuconazole 0.3kg, and composite fertilizer pulverizes, mixing, granulation makes centre (core) product; Again by urea formaldehyde (UF) and 1/3 tebuconazole 0.15kg, dilute with water, coating of spraying, to make sterilization slow releasing medicinal fertile.
Embodiment 2: get raw material: dimethyl pyrazole phosphoric acid salt 0.6kg, quinhydrones 0.3kg; Sodium lignosulfonate 0.2kg; Urea formaldehyde (MU) 0.3kg; Own azoles alcohol 0.9kg; Composite fertilizer 97.7kg.
Preparation method: first by above-mentioned raw materials, centre (core) product is made in dimethyl pyrazole phosphoric acid salt, quinhydrones, sodium lignosulfonate, 2/3 own azoles alcohol 0.6kg, composite fertilizer's pulverizing, mixing, granulation.Sterilization slow releasing medicinal fertilizer is made again with urea formaldehyde and 1/3 own azoles alcohol 0.3kg, mixing, dilution spraying coating.
Implementation column 3: get starting material: nitropyridine 0.8kg; Thiophosphoryl triamide 0.4kg; Ammonium lignosulphonate 0.35kg; Urea formaldehyde (UF) 0.6kg; Prochloraz 1.2kg; Composite fertilizer 96.65kg.
