Control measures of low light in greenhouse tomato

Prevention measures are mainly to improve lighting conditions in the shed as much as possible. When planting, increase the row spacing and reduce shading between the plants; keep the shed membrane clean and prevent the membrane surface from attaching water droplets and dirt; when the external temperature reaches 15°C in the late and mid-tomato period, properly expose some of the shed film. Let the sun shine directly into the shed. According to another test, a polyester aluminum film is used to splice a reflective screen that is 2 meters wide and 3 meters long. It is hung on the upper end of a post in a plastic greenhouse (greenhouse) and hangs down to the ground to add 40% to 43% light to the ground. Temperature increased by 3 °C ~ 4 °C, ground temperature increased by 1.8 °C ~ 2.9 °C, tomato yield increased 41.8% ~ 58.1%, and to improve the quality of the fruit; laying silver gray film or aluminum foil, but also increase the light intensity between plants, the tomato coloring Good, and can prevent premature aging of the lower leaves.

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.
