1. Increase ground temperature
Before entering the greening period, garlic should mainly raise the ground temperature. The cover on the film, such as leaves, crop straws, dead garlic leaves or dust, should be removed as soon as possible to increase the light transmittance and increase the ground temperature. The damaged mulch should be repaired in time to enhance the effect of heat preservation and warming, and promote the early greening of the mulch garlic.
2. Fertilizer and water management
After entering the "Jiaozhe" solar term, choose 3 to 5 days of sunny morning watering and topdressing, combined with watering acres to apply 20 kg of nitrogen fertilizer and 15 kg of potassium fertilizer. In case of special drought, you can water once in late March. In principle, do not water too early, otherwise it will easily cause disease or secondary growth of garlic. After each watering, it should be cultivated in time to increase the ground temperature and keep the roots and seedlings. Before and after the Ching Ming Festival, if there are yellow tips on the leaves, the second top dressing should be carried out in a timely manner, mainly with quick-acting nitrogen fertilizer, the use amount per mu is 20 kg, and the number of watering times should be increased in time. Promote plant growth.
3. Prevention and treatment of diseases
The low temperature in spring is prone to cold spring weather, which affects the normal growth of garlic. After the garlic enters the greening period at the end of March, the leaves can be sprayed with "Bihu" or brassinolide on the sunny afternoon to improve its resistance to adversity. Leaf blight and gray mold are common diseases of garlic in spring. In the early stage of the disease, small white dots appear on the leaf tip of garlic or light brown long oval spots on the surface of the leaf. When the disease is severe, the leaf dies, the base rots, and the garlic plant falls. When the diseased plant rate reaches 15%, use 50% Carbendazim 800 times solution or 20% Fenrusting 2000 times solution for spray control.

 Injection Device
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.
