Onion rot causes and performance symptoms
Onion rot is mainly due to root rot, the function of absorbing water and nutrients gradually weakened, and finally the whole plant died. The main manifestation is that the whole plant leaves yellow and withered until the last occurrence of dead trees. Rotting root is a common phenomenon in the production process of green onions, which, once it occurs, leads to a large reduction in production. The main reasons for this phenomenon are the following: 1. The heavy scorpion is the key factor causing the rot of the scallion roots. Due to the continuous cultivation for many years, the pathogenic bacteria in the soil increased, and the diseases of the heavy scorpion were unavoidable, which could easily cause the rot of the onion roots. 2. The roots are damaged. 3. Watering onion water pollution. 4. Herbicide damage. 5. Water accumulation roots. Onion leaves have low water transpiration, weak water absorption capacity in roots, less water consumption, and less moisture. If the water is flooded during the growing period, it will make the green onion fields accumulate disasters and produce roots, dry tips, yellow leaves and dead seedlings. Â Needle Tube
Syringes can also call Disposable Medical Supplies, Disposable Syringe With Needle and Plastic Needle Tube such as some scientific instruments in chromatography to inject through the rubber septum. Injecting gas into a blood vessel will cause an air embolism. The way to remove air from the syringe to avoid embolism is to turn the syringe upside down, tap it lightly, and squeeze out a little bit of fluid before injecting into the bloodstream.
In some cases where accuracy is not the primary concern of germs, such as quantitative chemical analysis, glass syringes are still used due to the small error of the glass syringe and the smooth movement of the push rod.
You can also inject some of the juices into meat with a syringe to improve taste and texture while cooking, or into pastries when baking. Syringes can also fill ink cartridges with ink.
