Containerized Oxygen Generator
ETR can combine all parts of the oxygen generation system into a customized container, including air compressor, refrigerate air dryer, filters, buffer tanks and Oxygen Generator. Even the optional oxygen booster and cylinder filling station.
Compressed air is purified through the air dryer and filters to a certain level for main plant to work with. Air buffer is incorporated for smooth supply of compressed air thus to reduce fluctuation of compressed air source. The plant produces oxygen with PSA (pressure swing adsorption) technology, which is a time proven oxygen generation method. Oxygen of desired purity at 93%±3% is delivered to oxygen buffer tank for smooth supply of product gas. Oxygen in buffer tank is maintained at 4bar pressure.

First, before rodent extermination Second, seed disinfection seed disinfection is an effective measure to control and reduce rice-borne diseases (such as bakanae, rice blast, rice leaf spot, bacterial leaf blight, etc.). Specific methods: The new agent 25% Prochloraz (ie, Shi Baoke) EC 2000 ~ 3000 times soaking 2 ~ 3 days, pay attention to early hybrid seeds should be soaked intermittently, soaking time can be shortened to 1.5 ~ 2 days. After draining and draining, use 10% imidacloprid wettable powder (or 35% good Anwei dry seed dressing) for dressing (1 kg seeds per 10 g, which can effectively prevent the damage of rice seedlings in seedling stage) and sowing. If 80% of the "402" antibacterial agent is used, the dilution factor should be controlled between 1000 and 1500 times, that is, use 2 ml of "402" one and immerse seed with 2 to 3 kg of clear water.
Third, the use of strong nutrients specific methods of use: Each 20m2 seedbed using the city strong strong nutrient 1.5 kg plus 18.5 kilograms of dry fine soil, fully mixed and spread evenly on the surface of the bed soil, and then repeatedly rake In the soil depth of 2 to 3 cm, then soaked with water to sow and cover the soil.
Fourth, early rice weed control technology for weeds in drylands In recent years, the city has comprehensively promoted the use of early rice dry sowing techniques. According to the analysis of trampoline weeds in the past few years, weeds with weeding techniques that are properly applied to the weeds have been lightly damaged, and weeding or weeding techniques that are not in place with weeding techniques have been significantly affected, among which weeds, broken rice dumplings, The dominant species are crabgrass, brackgrass, and tendongrass, among which poisoned weeds are also the source of rice virus disease. To this end, special advice on secondary chemical weeding techniques is provided:
1 For weedy weeds in planned and planted beds, about 7 days before ploughing, 10% glyphosate 500 ml or 41% Roundup 200 ml is used. 25 kg of fine spray of clean water to eliminate old grass and reduce the host site of ash and rice blast, so as to prevent the virus disease in rice. Spray when selected sunny, better moist effect on the bed.
2 After sowing the cover soil, apply 10 ml of 36% Drought-Reducing Emulsion (or 40% Drought-Resistant Milk) every 60 m2, and apply 5 kg of water evenly to the surface of the cocoon. After the cover is covered, the seeds are sprayed again to prevent the occurrence of phytotoxicity. The boring machine should be fully moistened during application, so that the water can reach saturation, but water can not be accumulated. After spraying, it is covered with a double layer of plastic film to moisturize, insulate, and increase the drug. effect.
Plant Protection Technology During Spring Broadcasting
"Surprised" will come and the temperature will begin to pick up, and spring sowing and breeding will soon begin. In order to ensure the safety of cereals, cultivate good disease-free plants, and lay a strong foundation for high-yielding rice, we should focus on the following key points of plant protection technology:
