Common potassium has a difference
Potassium sulfate is white or light yellow crystal, soluble in water and has low moisture absorption. As basal fertilizer, top dressing can be applied to all types of crops, especially avoid chlorine and potassium crops, the application should be properly concentrated.
Potassium nitrate white powder or crystal, soluble in water, low hygroscopicity.
Potassium dihydrogen phosphate is colorless to white crystalline or crystalline powder, soluble in water and stable in air. At present, it is mostly used for soaking and top dressing.
Biopotash can be used for seed dressing, rooting, and application to the soil. Application of bacteria is actually inoculated to the roots of crops, so that silicate bacteria release potassium, phosphorus, silicon, iron and other elements in the soil around the roots for root absorption and utilization.
Potash application note
Potassium fertilizer for soil application should first be placed in areas with severe potassium deficiency. From the soil texture, the content of available potassium in sandy soil is often low, and potassium fertilizer should be added. The content of available potassium in clay soil is often high, and it can be applied less or not. Potassium sulfate can be applied to soils that lack potassium and sulfur, and potassium chloride cannot be applied to saline soils.
Due to the application of crops in rainy areas or areas with good irrigation and drainage conditions, potassium chloride can be applied to most crops. For a few economic crops to improve quality, potassium chloride should not be used.
Rational use of potassium sulphate for tobacco, sugar crops and fruit trees is preferred. Due to the high cost of potassium sulphate, potassium sulphate can be used in high-efficiency and economic crop fields. Generally, in addition to a few chlorine-sensitive crops, field crops should use less expensive chlorine. Potassium.
Potash fertilizer is good
When the potassium-needling crop is in a fast growing period, it is best to spray on the foliage. When the crop roots develop, it is best to apply them deeply. Commonly used conservation tillage leaves more crop residues on the surface of the soil, which also leads to higher concentrations of potassium that accumulate on the soil surface and cannot penetrate deep into the soil. When soil moisture is good, these potassium can infiltrate smoothly, but when the soil is dry, it will limit the absorption of potassium. Since the crop is rooted deeper below the soil containing the most potassium in order to obtain enough water, this misalignment can lead to potassium deficiency in the crop. In this case, deep application of potash can significantly increase the availability of potassium.
The location of other nutrients also determines how much potassium is accessible to the roots of the crop. Nitrogen and phosphorus can stimulate crop root branching, and where these nutrient concentrations are higher, the proportion of roots will be higher. Applying potash fertilizer with nitrogen fertilizer and phosphate fertilizer in the same ditch can increase the chance of root contact with potassium.

Most endotracheal tubes today are made of polyvinyl chloride, but special tubes made of silicone rubber, latex rubber, or stainless steel are also widely used. Most tubes have an inflatable cuff that seals the trachea and bronchial tree to prevent air leaks and inhalation of stomach contents, blood, secretions and other fluids. Catheters without a capsule may also be used, but their use is mainly limited to pediatric patients (in young children, the cricoid cartilage is the narrowest part of the pediatric airway and usually provides an adequate seal for mechanical ventilation).
Types of endotracheal intubation include oral or nasal, with or without a capsule, prefabricated (e.g., RAE (Ring, Adair, and Elwyn) tubes), reinforced tubes, and double-lumen endobronchial tubes. For human use, tube ID sizes range from 2 to 10.5 mm. Sizes are chosen based on the patient's body size, with smaller sizes used for pediatric and neonatal patients. Tubes larger than 6 mm in diameter usually have inflatable cuff. Originally made of red rubber, most modern tubes are made of polyvinyl chloride. Those placed in the laser field could be flexible metals. Robertshaw (and others) developed a double-lumen endobronchial catheter for thoracic surgery. These allow ventilation from one lung while the other collapses, making surgery easier. After the surgery, the deflated lung is re-inflated to examine the fistula (tears). Another type of endotracheal tube has a small second luminal opening above the inflatable cuff that can be used for aspiration in the nasopharyngeal area and above the cuff to aid in extubation (removal). This allows the aspiration of secretions located above the cuff, which helps reduce the risk of chest infection in patients with prolonged intubation.
