Immediately after the flowering season of peach trees, peach trees are prone to produce aphids, which affect the yield of their fruits. So, how to completely control peach aphids?
Four measures are recommended to strictly control peach tree mites:
1. Apply 40% omethoate to the drug, add 1 part of multi-functional plant synergist, add 2 parts of water, mix and mix into a liquid. Use a brush to apply a 10 cm wide medicine ring on the trunk. If the bark is rough, the old skin can be scraped off and then applied. After coating, wrap it in newspaper or plastic film.
Second, the peach tree trunk injection is to use the iron cone on the trunk to puncture the hole from the top to the bottom, deep into the xylem, and then inject 40% dimethoate with a No. 8 syringe, close the orifice, 95% after 2 to 3 days The above mites kill.
Third, spray agents can choose to use a lot of drugs, commonly used in production: 35% endosulfan 1500 times liquid; 50% sputum fog 3000 ~ 4000 times liquid; 50% phoxim 1500 times liquid; 40% Omethoate 1500 times solution; 50% malathion (marathon) emulsifiable concentrate 1000 times solution; 10% imidacloprid (pampoo) wettable powder 5000 times solution. In order to improve the control effect, a certain amount of spreading agent can be added to the liquid medicine, and several agents should be used alternately, and a single agent should be avoided as much as possible.
Fourth, the natural enemies of the protection of natural enemies, such as ladybugs, scorpion flies, grasshoppers, parasitic wasps, etc., have a strong inhibitory effect on aphids. Therefore, it is necessary to spray a broad spectrum of pesticides as little as possible and avoid spraying during periods of natural enemies to protect natural enemies and use natural enemies to eliminate mites. This is of great significance for protecting the ecological environment of the orchard and producing pollution-free green fruits.
Chopped Graphite/Graphite Electrode in different materials have different definition of graphite pieces, some data and literature is not very big graphite particles are called graphite pieces (such as Graphite Powder) some is graphite products have a certain size, for Graphite Broken into patches, we here say of graphite for a second, usually called graphite blocks. Graphite is produced from graphitization and machining process of graphite products. It is used as additive and conductive material in the manufacture of graphite waste in steel and foundry industries, and can also be processed according to customer's requirements. They are also widely used in electric arc furnaces (steelmaking) and electrochemical furnaces (metallurgical and chemical industries).
Main use of graphite
Graphite pieces due to its low ash content, conductive and heat conduction performance is good, so there are a wide range of USES, can be added to the formula of less ash or dust products, graphite broken broken into small particles commonly use. Ingredients to add a certain amount of graphite, the plastic paste after kneading, especially during extrusion can reduce the friction resistance paste to squeeze the mouthpiece, to improve the coefficient of pressure type. Graphite pieces of coal adsorption properties of asphalt is better, to join the carbon block can rise to reduce the "short" waste (i.e., the product after roasting top produce honeycomb structure), and can improve the thermal conductivity of the carbon block and alkali corrosion resistance. The electrode paste used in hermetically-sealed thermal furnace is added to a certain amount of graphite to increase the conductivity and thermal conductivity of the electrode paste and accelerate the sintering speed of electrode paste. When the graphite is ground into small particles or fine powder, it is also used as raw material for the production of graphite chemical equipment (such as graphite-resin tubes). The graphite can also be used as a carbon addition agent for the electric furnace.
Graphite classification
1. Raw and broken. It is a raw blank that is not qualified after molding.
2. Roasting is the cutting debris that is recovered after the roasting of raw billet and after inspection of unqualified waste and the processing of calcined products.
3. The graphite is broken, and it is inspected by the graphite-producing waste and the cutting debris produced by graphite products in the process of processing.
