Three measures to prevent tomato rot
Shading should be moderate to avoid insufficient lighting In order to reduce the temperature of the shed, many sheds are covered with sunshade nets, but many vegetable farmers do not control the sunshade nets. The sunshade nets cover all day, resulting in less light, less light, and the incidence of rot disease. high. It is recommended to cover the shade net only at noon on sunny days, and remove it in the evening and rainy days to ensure the time and light intensity of the tomato. Rational fertilization to avoid imbalance of nitrogen and potassium When the tomato fruit enters the color-changing period, the nitrogen nutrient level in the plant is too high, which will affect the formation of lycopene, resulting in uneven color change and formation of tendon. In order to prevent premature aging of tomato in summer, many vegetable farmers are less likely to have nitrogen fertilizer, and the chance of producing rot fruit is greater. Therefore, when the tomato fruit is expanded, the high-potassium water-soluble fertilizer can be appropriately increased to reduce the application of the high-nitrogen fertilizer. It can also be sprayed with potassium dihydrogen phosphate 200-300 times to quickly replenish nutrients and reduce the chance of fruit rot in the later stage. Raise the root system to avoid affecting the absorption of water and fertilizer At present, the temperature is higher and the amount of water evaporation is larger. Some vegetable farmers over-watering in order to promote the rapid growth of tomato, resulting in root injury, which leads to a decrease in the ability of roots to absorb water and nutrients, and promotes the occurrence of tendon rot. It is recommended that vegetable farmers water water reasonably to avoid over-slipping water after pouring over water. When watering, avoid high temperature period, and combine watering to apply functional products to maintain root system. Disclaimer: Some articles on this website are transferred from the Internet.

• 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.
