Can dry water be closed after live blocking?
Wu Ronglang, Huaiyin District, Huai'an City: After the sowing of dry direct seeded rice fields, a soil-enclosing agent was applied. Now that the soil is dry, can it not be filled with water?
Answer: You can irrigate water, but you should speed up irrigation to ensure that the surface is not long-term accumulation of water, otherwise it may produce phytotoxicity. In particular, in the field where oxadiachlor is applied, it is better not to inject water in the emergence stage of rice when the soil moisture satisfies rice emergence.
High Flow Nasal Cannula(HFNC) oxygen therapy is a form of non –invasive respiratory support, which comprises an air oxygen blender, an active humidifier, a single heated circuit and a nasal cannula. It delivers adequately heated and humidified medical gas up to 10-60L/min, and is considered to have a number of physiological effects: reduction of anatomical dead space, PEEP effect, constant fraction of inspired oxygen and good humidification.
It is widely used in RICU and ICU.
