Abstract
The invention relates to a weeding slow-release pesticide fertilizer and a preparation method thereof, belonging to a pesticide fertilizer/slow-release fertilizer combined multifunctional weeding slow-release pesticide fertilizer. The slow-release fertilizer is composed of a nitrification inhibitor nitropyridine or dimethyl pyrazolyl phosphate or pentachlorophenol, a urease inhibitor thiophosphoryl triamide or hydroquinone, a phosphorus activator ammonium lignosulfonate or sodium lignosulfonate, urea formaldehyde (UF or MU), a weedicide composition (composed of pentachloroflumetsulam, bensulfuron methyl or pyrazosulfuron-ethyl or ethoxysulfuron, pretilachlor or butachlor or metolachlor, and mefenacet), and a compound fertilizer. The weeding slow-release pesticide fertilizer enables the release of the pesticide and fertilizer to be synchronous with the demands of the crops by using the slow release technique, sufficiently prolongs the pesticide effect and fertilizer efficiency period, enhances the utilization ratio, can satisfy the pesticide fertilizer supply for the whole crop breeding season by one application of the slow-release pesticide fertilizer, and ensures stable and high yield of the crops.
Description
Technical field: the technical field that the invention belongs to medicine fertilizer, particularly relates to fertile Multi-functional herbicidal power slow releasing medicinal fertilizer combined with slow-release fertilizer of a kind of medicine and preparation method thereof.
Background technology: the developing direction of fertilizer is high density, compound, multi-functional and long-acting slow-release high utilization rate; The developing direction of agricultural chemicals be anti-ly to cure the disease, worm, the efficient and low toxicity (to people and animals and environment) of crop smothering, wide spectrum, long-acting.Medicine fertilizer is the product that agricultural chemicals and chemical fertilizer combine, and can provide crop alimentary demand, can effectively prevent again curing the disease, worm, crop smothering.
What develop medicine fertilizer in the world the earliest is Japan, the Weed removal medicinal fertilizer containing pentachlorophenol (PCP) development and production in 1964; The U.S. and the USSR (Union of Soviet Socialist Republics) also Weed removal medicinal fertilizer of research and production containing prometryn subsequently.China starts the Developing Application of medicine fertilizer the eighties in eighties of last century, has the weeding wheatland medicine in Qinghai fertile; The herbicide urea in Zhejiang, Ningxia; Also have the Chinese Academy of Sciences south soil institute coating medicine fertilizer; The precious medicine of Huanglong of Central-South agriculture section is fertile; The Weed removal medicinal fertilizer for paddy rice in rural area, Guangxi and the Avrmectin medicine fertilizer of Fu Erwo and benzyl fourth Weed removal medicinal fertilizer for paddy rice etc.
After mostly current existing technology is agricultural chemicals and chemical fertilizer to mix by a certain percentage, make various medicine through granulation fertile, its Pesticides lasting period is short, and fertilizer efficiency period also only has 30 ~ 50 days; And crop generally needs the medicine phase and need the fertile phase all at 90 ~ 120 days.The common drug fertile lasting period is short, will repeatedly dispenser and topdressing in agriculture production; The utilization ratio of its agricultural chemicals and chemical fertilizer also only has 30 ~ 40%, and major part volatilization and leaching loss enter air and water body, cause the serious wasting of resources and environmental pollution.
Summary of the invention:
Goal of the invention: in order to solve the shortcoming and defect part of above-mentioned prior art, the present invention proposes a kind of weeding slow releasing medicinal fertile, that slow-release fertilizer is combined with medicine fertilizer, the fertile slow releasing of medicine can be made, drug effect, fertilizer efficiency period extend, and utilization ratio improves, and need fertile and need medicine to reach synchronous and coordinate with crop, can be disposable employed, the medicine of crop whole breeding time, fertile demand can be met.
Technical scheme: the present invention solves by the following technical programs:
A kind of weeding slow releasing medicinal is fertile, it is characterized in that: the effective constituent of this medicine fertilizer is made up of following component by ratio of weight and the number of copies:
Nitrification inhibitor: 0.1 ~ 0.5%;
Urease inhibitor: 0.05 ~ 0.3%;
Phosphorus element activator: 0.1 ~ 0.5%;
Urea formaldehyde: 0.1 ~ 1.0%;
Weedicide: 0.2 ~ 3.0%;
Composite fertilizer: 94.7 ~ 99.45%.
Described nitrification inhibitor is: nitropyridine (N-Serve) or dimethyl pyrazole phosphoric acid salt (DMPP) or pentachlorophenol (PCP); Urease inhibitor is: quinhydrones (HQ) or thiophosphoryl triamide (NBPT); Phosphorus element activator is: ammonium lignosulphonate or sodium lignosulfonate; Urea formaldehyde is poly-MU (UF) or methylene urea (MU); Weedicide is: pentachloro-sulphur grass amine, benbbensulfuronmethyl, pyrazosulfuronmethyl, ethoxysulfuron, two second sulphur are grand, the combination of the third careless amine, Butachlor technical 92, metolachlor or mefenacet; Composite fertilizer is by the fertile composite fertilizer's special fertilizer formed such as nitrogen, phosphorus, potassium.
The preparation method of weeding slow releasing medicinal fertilizer is: by a nitrification inhibitor for said ratio, urease inhibitor, phosphorus element activator, composite fertilizer and 2/3 weedicide through pulverizing, mixing, granulation makes intermediates (core); Again the weedicide blending water dilution of urea formaldehyde and 1/3 is adopted spraying film-coating technique, urea formaldehyde and part weedicide are wrapped on above-mentioned intermediates (core), final obtained weeding slow releasing medicinal is fertile.
Advantage and effect:
1, adopt nitrification inhibitor, urease inhibitor, phosphorus element activator, urea formaldehyde and weedicide carry out scientific compatibility, organically combine, make it produce synergy, send out and press best effect.
2, its preparation adopts multiple slow release method (adding inhibitor, urea formaldehyde and coating process) first intermediates (core) to be made by suppression, part weedicide and composite fertilizer; Be wrapped in above-mentioned core with urea formaldehyde and part weedicide again.Make the dissolving of its fertilizer and agricultural chemicals, release reaches synchronous with the demand of crop, and namely crop has sufficient fertilizer supply and agricultural chemicals protection in seedling stage, mid-term and later stage.
3, fully extend drug effect and the fertilizer efficiency period of medicine fertilizer, improve the utilization ratio of medicine fertilizer, reach agriculturally applied once, the crop whole breeding time of the demand to agricultural chemicals and fertilizer can be met, save labour, reduce costs, economize on resources, reduce environmental pollution.
4, the multiple weeds in paddy field can effectively be killed as barnyard grass, Semen Euphorbiae, Sha, grass, short, arrowhead, Herba Marsileae Quadrifoliae, Herba potamogetonis distincti etc.; Fertilizer nutrient is complete, and fertilizer is steady, guarantees stable and high yields.
Embodiment:
Embodiment 1: get raw material: nitropyridine 0.2kg; Thiophosphoryl triamide 0.15kg; Ammonium lignosulphonate 0.2kg; Urea formaldehyde 0.5kg (UF); Pentachloro-sulphur grass amine 1.2kg, composite fertilizer 97.75kg.
By above-mentioned weight by nitropyridine, thiophosphoryl triamide, ammonium lignosulphonate, 2/3 pentachloro-sulphur grass amine and composite fertilizer pulverize, and mixing granulation makes intermediates (core); Again urea formaldehyde (UF) and the mixing of 1/3 pentachloro-sulphur grass amine, dilution are sprayed into coating machine, finally make weeding slow releasing medicinal fertile.
