Tomato calcium supplement measures

Calcium-deficient tomatoes usually have short plants, water-stained light yellow-brown to dark green-brown spots on the navel of the fruit, uneven surface, and necrosis of diseased tissue (ie, umbilical rot). During the period of fruit expansion and maturity, if the calcium supply is insufficient, fruit cracking will occur, resulting in poor coloration and loss of luster. So how should tomatoes supplement calcium scientifically?

Spray 0.3%-0.5% calcium nitrate aqueous solution, or 0.1%-0.2% calcium chloride aqueous solution, or 400-500 times active calcium aqueous solution, or 600-800 times fluid calcium aqueous solution on the leaf surface, usually sprayed once every 7-10 days, Spray 2-3 times continuously to get a good calcium supplement effect. The ripening period of tomato fruit is the best time to supplement calcium.

In addition, using superphosphate or calcium-magnesium-phosphate fertilizer as base fertilizer, 80-100 kg per mu, can significantly increase the calcium content of the soil. Adding retorted human, livestock and poultry manure and biological bacterial fertilizer can make the soil The content of active calcium is significantly increased, which is beneficial to the absorption and utilization of tomato roots and avoids calcium deficiency during tomato growth and development. If the tomato is planted in acid soil, when planting tomatoes on the ground, spread 50-60 kg of hydrated lime powder per acre to neutralize the acidity of the soil, increase the calcium in the soil, and ensure that there is sufficient calcium for the growth of tomatoes. need.

Radial Artery Compression Devices

Radial artery compression devices, also known as radial artery compression devices or wristbands, are used to achieve hemostasis after a transradial cardiac catheterization procedure. The device is applied to the wrist and inflated to compress the radial artery, which is the artery that supplies blood to the hand and fingers. This compression helps to prevent bleeding and hematoma formation at the site of the catheterization.
Radial artery compression devices are preferred over traditional compression methods such as manual compression because they are more effective, comfortable for the patient, and allow for earlier ambulation and discharge. They also reduce the risk of complications such as radial artery occlusion and nerve injury.
In addition to cardiac catheterization procedures, radial artery compression devices may also be used after other procedures that involve the radial artery, such as transradial access for arterial blood gas analysis or for the placement of intra-arterial lines.
