In the early stage of wheat seeding and emergence, if the wheat seedlings with the lack of seedlings are found, the following methods can be adopted: replanting in time. In order to ensure the whole seedlings, the wheat seedlings should be inspected in time after the emergence of the seedlings, and the wheat fields with abnormal seedlings and broken strips should be robbed in the early stage of emergence, and the seeds of the same variety should be used for replanting. Shifting and absorbing. In the wheat trifoliate stage, the whole field is better than the seedlings, and only a few places lacking the nest and the seedlings of the wheat field can be transplanted in the Honda to replenish the soil, and the root water is transplanted after transplanting to replenish the seedlings. When transplanting, it is necessary to put on the water without under pressure, bury it and cover it, and then properly apply fertilizer to reduce the seedlings. Drought hydration. For the lack of seedlings due to drought, it should be timely watered to make up, once a day, even for 3-5 days, to promote normal growth of wheat seedlings, seedlings and more. For improper injury to the seedlings, it should be replenished with 2-3 times of water, and then soiled after watering. Topdressing promotes strength. For the wheat field where the emergence of each nest is relatively uniform, but the basic seedlings are insufficient, it is possible to take the quick-acting nitrogen fertilizer during the emergence to the three-leaf stage, and apply the seedling fertilizer early. It can promote early tillering, strong growth, optimize individuals, achieve winter and early development, and win high yields. Get rid of the soil. If the seedling is too deep to cause lack of seedlings, part of the soil can be removed, and then irrigation and cultivating can be combined to improve the soil ventilation and promote lateral root development. Control pests and diseases. The pests and diseases that often occur before winter in wheat are mainly root diseases and underground pests. It is necessary to take timely prevention and control measures to eliminate pests and diseases, and let the thin wheat seedlings turn into strong seedlings as soon as possible. Avoid salt damage. In the case of wheat fields lacking seedlings due to salt damage, the soil should be ploughed in time to reduce evaporation on the ground and avoid salt return. Take the salt washing or salting method to reduce the salt content of the soil.

• Warmed humidified air is better than cold, dry gases even in short cases.
When a patient`s trachea is intubated or a supraglottic airway device is placed in situ, the normal warming, humidifying and filtering functions of the upper airways are bypassed. Hence, gas delivered to the patient needs to be artificially conditioned to replace these lost functions Heat and moisture exchangers (HMEs) are intended to conserve a portion of the patient`s exhaled heat and moisture, and condition inspired gas by warming and humidifying it. Breathing system filters are intended to reduce the transmission of microbes and other particulate matter in breathing systems.
Devices that contain both filters and HME are called Heat Moisture Exchanger Filters (HMEFs). It is not ideal to distinguish these two common filters with "static" and "folds", because these two types of filters rely on electrostatic charge to a certain extent to keep the particles in the filter material, two types All materials can be folded. The main difference between the two types is the density of the fibers. For "electrostatic" filter materials, the density of the fibers is relatively low, and the electrostatic charge (fiber or triboelectric charge) on the fibers is high. For "pleated" filters, the density of the fibers is high: this leads to increased resistance to gas flow; the pleated material increases the surface area, thereby reducing the resistance. This type of filter is also called "hydrophobic" (because the surface of the filter material repels water) or "mechanical". In this review, the terms "electrostatic" and "pleat" will be used to distinguish these two types of filters.

Why use Heat Moisture Exchanger Filters (HMEF)
• HMEF is passive humidification with bacterial/viral filtration efficiency.
Gases emerging from Anesthesia machine are dry and room temperature (cold)
• Tracheal intubation or use of laryngeal mask airway bypasses upper airway modifying pattern
of heat and moisture exchange, lungs need 37° & 100% relative humidity.
• Cilia can stop beating with impaired mucocilliary function includes sputum retention &
increased risk of infection .
Used in anesthesia and respiratory system, our B/V Filter is designed for the
protection of the patient, hospital personnel and the equipment from
potential microbial contamination.
Features:
Lightweight reduces torque on tracheal connection.
ISO connectors allow for safe and secure connections.
Gas sampling port with cap for easy, safe monitoring of expired gases.
