Cultivating kidney beans involves careful selection of high-quality varieties, such as May Fresh, Red-billed Swift, 28-2, August, Panxiang, Jiangsu Maohong, and Zhejiang 512. These varieties are known for their yield and adaptability to different growing conditions. The optimal sowing period is between late April and mid-July, or from late June to early November, depending on the region and climate.
For planting density, the 28-2 variety should be planted in rows spaced 1.3–1.4 meters apart with two rows per bed. Each hole should have three plants, spaced 20–23 cm apart, resulting in about 140,000–160,000 plants per acre. However, for later-maturing varieties like August, which tend to produce more foliage and branching, it's better to increase the spacing to 30–33 cm, planting two per hole, with around 7,000–8,000 seedlings per acre. When vines start to grow, they should be supported using a herringbone trellis system to ensure even distribution of stems.
Fertilizer management plays a key role in the growth of kidney beans. During the seedling stage, apply 3–5 kg of urea per acre. After flowering and pod formation, use 6–10 kg of nitrogen fertilizer, 1–4 kg of phosphate, and 2–4 kg of potash, split into 2–3 applications along with irrigation. To enhance yield during harvest, spray 1–2% potassium dihydrogen phosphate every five days. After 25–30 days of harvesting, apply quick-release organic fertilizer or NPK compound fertilizer (30–50 kg per mu) either at the edge of the trench or directly on the soil surface. Watering should be carefully managed to prevent leggy growth before flowering. In non-mulched fields, regular weeding and loosening of the soil is essential. If there's no rain after flowering, water once every five days to maintain moisture.
Pest control is crucial, especially for aphids, bean pods, cowpea mycoticosis, and cowpea rust. Regular monitoring and timely treatment are necessary to avoid crop damage. For dwarf beans, after deep soil preparation, apply 30–50 kg of phosphate fertilizer, 10 kg of compound fertilizer, and 15 kg of potassium fertilizer per acre. Mix thoroughly and create raised beds 1.8–2.0 m wide with 20–25 cm spacing and 30 cm depth.
Autumn sowing for dwarf beans should occur between mid-July and early August. Choose suitable dwarf varieties and allow seeds to sun-dry for one or two days before planting. Harvest can begin approximately 60 days after sowing. Plant spacing should be 30–35 cm, with 1–2 seeds per hole, yielding around 2 kg per mu. Ensure the soil isn't too deep when planting, and water lightly after sowing if needed.
Fertilizer application for kidney beans includes watering with 10% manure or 3–5 kg of urea after the second pair of true leaves appear. When the plant starts to vine, use a ternary compound fertilizer solution. Apply 6–9 kg of fertilizer per acre, keeping nitrogen levels under control. At the time of flowering, apply two doses of compound fertilizer, each 12–15 kg.
During the flowering phase, spray 1,500 times diluted farmer flowering essence or 5–25 mg/L gibberellin solution to promote flowering and improve pod setting. During the blooming period, applying 5–25 mg/L B-Naphthalene Acetate or 0.3% potassium dihydrogen phosphate can help reduce flower drop.
Harvesting should be done promptly, typically 10–15 days after flowering, to ensure quality and maximize yield. Proper timing and technique are essential for successful kidney bean cultivation.
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.
