The invention provides a synergist using a 2-cyclopentenone-containing compound as a nitrogen-containing fertilizer. The synergist comprises the components by weight: 5-25 parts of benzoic acid, 3-20 parts of 2-cyclopentenone, 1-30 parts of dihydrojasmonone, 10-60 parts of glycerol and 20-55 parts of yeast liquid powder. The novel synergist is applied to the nitrogen-containing fertilizer, and the nitrogen-containing fertilizer can be prepared. The addition amount of the synergist in the nitrogen-containing fertilizer is 0.1-1% of the nitrogen content in the fertilizer. The preparation method comprises the following steps: a first method comprising the steps of spraying and wrapping the synergist on the surface layer of the fertilizer; a second method comprising the steps of mixing with a grain-level powdery nitrogen fertilizer, and granulating the nitrogen fertilizer to form a stable fertilizer; a third method comprising the steps of adding into a urea production system to form urea; and a fourth method comprising the steps of spraying and granulating ammonium phosphate. The synergist has a bidirectional regulation function, can inhibit hydrolysis of urea to play a role in urease inhibition, can delay conversion from ammonium nitrogen to nitrate nitrogen to play a role in nitrification inhibition, and also has the advantages of good action effect, environmental protection and the like.

The present invention discloses a magnesium and magnesium alloy surface cladding preparation method which comprises the following procedures: a) the surface is cleaned up; b) electrolyte for micro-arc oxidation is a water-based solution, wherein, the concentration of sodium fluoride is between 1 g / L and 40 g / L; the concentration of sodium phosphate is between 1 g / L and 100 g / L; the sodium fluoride and the sodium phosphate can be used separately or in a combined way, or sodium hydroxide with the concentration between 0.05 g / L and 10 g / L is further added to use; c) the surface is treated bychemical plating and / or d) electroplating; water cleaning is only required among the procedures. The invention based on the knowledge of the related mechanism of plating technology and micro-arc oxidation technology makes the best of the advantages in particular that the micro-arc oxidation ceramic film has the characteristics of corrosion resistance and porosity, and combines the surface ceramictechnology and the surface alloy technology organically and solves the problems of complex working procedures, high cost, large pollution, imperfect effect, etc., in the prior plating art. With the method provided by the invention, a cladding with uniformity, smoothness, a compact structure and excellent performance can be achieved.

The invention discloses a herbicide composition containing chamomile essential oil and pyrazosulfuron-methyl and its application, and belongs to the technical field of herbicides. The active ingredients of the herbicide composition include: chamomile essential oil and pyrazosulfuron-methyl. The invention provides The herbicide composition exhibits a good synergistic effect within a certain proportion range, the herbicidal effect of the composition is significantly improved compared with a single agent, the herbicide spectrum is expanded, and the amount of chemical herbicides is reduced at the same time, and the residue is reduced. The potential threat of pesticides to the environment has also been alleviated; the active components of the composition in the present invention are plant-derived non-toxic components and low-toxic pesticides, and along with the implementation of my country's measures to ban highly toxic and highly toxic pesticides, the compositions of the present invention will It has become one of the most suitable products to replace highly toxic pesticides and has broad application prospects.

The invention discloses a synergistic herbicidal composition and its preparation and application. The synergistic herbicidal composition consists of glufosinate-ammonium, 1,2,4-triazol-3-one, linalool and optional adjuvants. The herbicidal composition can promote the absorption and conduction of effective ingredients by weeds, so that the onset time is significantly shortened, the weeds are not easy to turn green after the onset of effects, the biological activity of glufosinate-ammonium for killing weeds is significantly improved, and at the same time resistance to weeds Grass has a good control effect. While increasing the herbicidal effect of glufosinate, it can reduce the unit dosage and use frequency of glufosinate, thereby reducing the pollution of glufosinate to the environment and slowing down the resistance of weeds to glufosinate. It is of great significance to the comprehensive management of weed resistance.

The invention provides a method for authentication processing in a broadband network, the core of which is: record the address information of the network terminal in the online state; when receiving the authentication request message of the network terminal, obtain the address of the network terminal sending the authentication request message information; match the acquired address information with the recorded address information, and determine the network terminal matching the recorded address information; according to the authentication request message of the network terminal matching the recorded address information, the network The terminal is authenticated. The present invention utilizes the authentication request message of the network terminal and the address information of the network terminal to ensure the real-time performance of the detection of the network terminal being hanged, to ensure that the normal network terminal can surf the Internet casually and normally, and to avoid forcing the normal network terminal to go offline The phenomenon of dispersing the processing load of network equipment; thereby achieving the purpose of improving the reliability of authentication processing, reducing the potential threat of network equipment, and reducing the potential cost of network equipment authentication processing.
