Bitter gourd has good soil looseness and good permeability. The sandy soil with deep soil layer and rich organic matter is most suitable. The cultivation of bitter gourd on sandy loam soil, due to good permeability, rapid growth of seedlings, strong early growth, but relatively easy to decline, low yield, it should be added enough organic fertilizer. Cultivation of bitter gourd in sticky soil, seedling growth is slow, the soil is easy to compact, and permeability is poor. Therefore, it is necessary to increase organic fertilizer to improve the soil structure, and pay attention to cultivating soil to improve soil permeability. Bitter gourds require fertile soil. The physical and chemical properties of the soil determine the fertility of the soil, and the physical and chemical properties are related to the organic matter. Soil organic matter is the most active part of the soil and the basis for soil fertility. Soil organic matter is less than 20 cm in the topsoil, generally 0.2% to 0.3%, and the optimum content is 5% to 7%. The high temperature in the south, the decomposition of organic matter is fast, and the content of organic matter is low. When the soil organic matter content is below 15%, with the increase of organic matter content, the yield of crops also increases. Therefore, in addition to the application of fertilizer, organic fertilizers should also improve the physical and chemical properties of the soil and increase the role of water-stable aggregate structure in the soil. At present, the promotion of plastic film mulching cultivation is also one of the measures to improve soil physical and chemical properties, and the effect of increasing production is quite obvious. Bare gourd cultivation is also preferred for mulching, because mulching improves the conditions of water, heat, and gas in the soil, and the basal fertilizer is more abundant, which promotes the development of the root system, plant growth is strong, and the yield and quality are high. improve. Bitter gourd should be cultivated in slightly acidic soil, soil PH value of 6-6.8, peracid or over-alkali are not conducive to the growth and development of bitter gourd.

Why invasive blood pressure monitoring is needed?
Arterial blood pressure is most accurately measured invasively through an arterial line. Invasive arterial pressure
measurement with intravascular cannula involves direct measurement of arterial pressure by placing a cannula needle in an
artery (usually radial, femoral, dorsalis pedis or brachial).
The cannula must be connected to a sterile, fluid-filled system, which is connected to an electronic pressure transducer. This
invasive technique is regularly employed in human and veterinary intensive care medicine, anesthesiology and for research
purposes.
IBP (Invasive Blood Pressure)provides various clinical values. In surgical applications, the blood pressure is continuously and
accurately measured, allowing medical staff to react to changes faster. For example, if Anesthesia is given to the patient, the
continuous monitoring can confirm it has not caused an adverse effect to the blood pressure. During certain operations,
maintaining blood pressure in a very narrow range is critical; IBP creates the capability to monitor and maintain pressures. IBP
also plays a critical role in situations where blood pressure is expected to fluctuate rapidly. By continuously monitoring the
pressure, medical staff can be more timely and accurate in their reactions.
When to use:
NIBP(Non-Invasive Blood Pressure) is not possible to use or when greater accuracy is required.
Blood pressure must be maintained in very narrow range for a period of time.
Blood pressure is expected to fluctuate significantly.
Continuous blood analysis is required.
