Pumpkins bloom a lot, but they are often not fruitful, resulting in low yields of pumpkins. The reason is mainly caused by insufficient sunlight, excessive nitrogen fertilizer, and insufficient pollination. The following methods are recommended to allow pumpkins to sit more:
Method 1: When the pumpkin vine grows to 2 meters, the main vine growth point is removed, so that the main vine grows 3 to 4 vines, and the flowering and cascading.
Method 2: Support the scaffolding for the pumpkin. When the pumpkin vine grows to 2 meters, the vine is placed on the shed, which can improve the light transmission and ventilation conditions, reduce the pests and diseases, and thus increase the sitting rate by more than 40%.
Method 3: Prevent the pumpkin from growing. If the pumpkin melon grows long, it will cause fewer melons. For example, if a crack is cut 30 cm from the root on the vine, the block charcoal can suppress the length. At the same time, we must pay attention to controlling the amount of nitrogen fertilizer applied and increasing the application of phosphorus and potassium fertilizer.
Method 4: Auxiliary pollination of pumpkin. First, the female flowers that are open to pollination are covered with melon leaves to prevent rainwater from invading. At 9 o'clock the next morning, the male flowers on the different plants are taken over the female flowers, and then removed after 3 days.
Method 5: On the melons that have been flowering, remove the leaves and old yellow leaves in time, and remove 30% of the male flowers.

• 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.
