Question: Now that dry rice has two hearts and one heart, can we fight herbicide? If it can, what medicine? Answer: For dry-land rice planted by direct seeding, it is generally required that the soil is closed before seedlings after sowing. Commonly used drugs include butyl oxalate and pendimethalin. Generally, at the 2nd leaf stage of rice, the weeds in the field are almost equal, and when the grass age is below 4 leaf stage, the weeds are removed by using the stem and leaf treatment agent according to the grassy phase (type, amount of weeds). Dry rice fields usually have more crabgrass, goosegrass, millet, and valerian, and other broadleaf grasses and sedges. You can use Fumeishi's Han Qiuhao 10% Fazodicarb EC to control Qianqin, crabgrass, goosegrass, valerian, add azosulfuron-methyl, 2A, 4-chloro- broadleaf weeds and Sedge. Or use cyhalofop- butyl (thousands of gold, etc.) and penoxsulam (Opadry) to control a wide range of grass weeds and broadleaf weeds. Try to apply when the grass age is small. When the grass age is large, increase the dosage.
Oxygen Cylinder Filling System
With PSA principles, ETR Oxygen Cylinder Filling system can produce 93%±3% purity oxygen gas from compressed air directly. ETR oxygen cylinder filling system is consisted of Atlas screw air compressor, refrigerated air dryer, compressed air filter, air buffer tank, ETR Oxygen Plant, oxygen buffer tank, oxygen booster, cylinder filling station and HMI control cabinet.
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. With an oxygen booster, the oxygen pressure can be to 150bar and fill in cylinders.
