Cultivation of kidney beans involves careful selection of high-quality varieties such as May Fresh, Red-billed Swift, 28-2, August, Pan-xiang, Jiangsu Maohong, and Zhejiang 512. These varieties are known for their adaptability and yield potential. The best time for sowing is from late April to mid-July for direct seeding or transplanting, while the nursery transplant period can extend until early November.
For optimal growth, proper planting density is essential. For varieties like 28-2, a spacing of 1.3–1.4 meters wide with two rows per bed is recommended. Each hole should contain three plants, spaced 20–23 cm apart, resulting in approximately 140,000–160,000 plants per acre. However, for later-maturing varieties such as August, which have more foliage and vigorous branching, it's better to increase the spacing to 30–33 cm per hole, planting two plants per hole, with a total of 70,000–80,000 seedlings per acre. As the vines grow, they should be supported with a herringbone trellis system to ensure even spread and good air circulation.
Fertilization plays a key role in the growth cycle. During the seedling stage, apply 3–5 kg of urea per acre. After flowering and pod formation, use 6–10 kg of nitrogen, 1–4 kg of phosphate, and 2–4 kg of potash, divided into 2–3 applications with irrigation. To enhance yield and quality, spray 1–2% potassium dihydrogen phosphate every five days during the harvesting period. After 25–30 days of harvest, apply a quick-release organic fertilizer or NPK compound fertilizer at 30–50 kg per mu. This can be applied along the edges of the furrows or directly on the soil surface.
Water management is crucial. Avoid overwatering before flowering to prevent leggy growth. In non-mulched fields, regular weeding and loosening of the soil are necessary. If no rain occurs after flowering, water every five days to maintain moisture.
Pest control is also important. Regular monitoring and treatment of aphids, bean pods, cowpea mycoticosis, and cowpea rust are essential to protect the crop.
For dwarf bean composting, 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 with a width of 1.8–2.0 meters and a depth of 30 cm. Sow dwarf bean varieties between mid-July and early August, after sun-drying the seeds for a day or two. Harvest begins around 60 days after sowing, with a plant spacing of 30–35 cm and 1–2 seeds per hole, yielding about 2 kg per mu.
During the growing phase, apply 10% manure or 3–5 kg of urea after the second pair of true leaves appear. When the plants start to vine, use a ternary compound fertilizer, applying 6–9 kg per acre and carefully controlling nitrogen levels. At the beginning of flowering, apply two doses of compound fertilizer, each at 12–15 kg per acre.
To promote flowering and reduce flower drop, spray a 1500-times diluted solution of flower-promoting essence or 5–25 mg/L gibberellin before flowering. During the flowering stage, using 5–25 mg/L B-Naphthalene Acetate or 0.3% potassium dihydrogen phosphate foliar spray can help prevent premature flower fall.
Harvesting should be timely, typically 10–15 days after flowering, depending on the variety and growing conditions. Regular monitoring ensures that the beans are harvested at peak quality.
Disposable Endo Linear Cutting Stapler
An abdominal surgery disposable endo linear cutter is a surgical instrument used for cutting and stapling tissues during abdominal surgeries. It is a disposable device that is used once and then discarded. The endo linear cutter is designed to make precise cuts and staple the tissue together at the same time, reducing the risk of bleeding and improving the healing process. It is commonly used in procedures such as gastric bypass, colon resection, and other gastrointestinal surgeries. The device comes in different sizes and lengths, depending on the specific surgical procedure.
Advantage
1. Reduced risk of infection: Disposable internal cutting linear cutters are sterile and are used only once, minimizing the risk of infection.
2. Consistency: Since disposable cutters are manufactured under strict quality control measures, they offer consistent performance.
3. Convenience: Disposable cutters are easy to use and do not require any special maintenance or cleaning after use.
4. Cost-effective: Disposable cutters are often more cost-effective than reusable cutters, as they eliminate the need for expensive sterilization and maintenance procedures.
5. Improved patient safety: Disposable cutters reduce the risk of cross-contamination and infection, thus improving patient safety.
