Field Management of Fresh Edible Beans

Fresh edible soybeans are a highly nutritious and versatile vegetable variety that can be quickly frozen to maintain their freshness. This crop has become increasingly popular in the annual supply market due to its high economic value, with farmers often earning two to four times more than they would from mature soybeans. Proper field management is essential for maximizing yield and quality. Here are the key practices to follow: 1. **Scientific Fertilization** Fresh soybeans require a balanced and timely fertilizer application. They are particularly sensitive to nitrogen, so it's important to apply fertilizers in stages. Start with a base fertilizer of 30–40 kg of compound fertilizer or 800–1000 kg of organic manure per acre. During the seedling stage, apply 10–12 kg of urea to promote strong growth. At the flowering stage, which is critical for pod development, apply 5–10 kg of urea and 5–10 kg of potassium chloride. This helps ensure healthy blossoms and better yields. 2. **Effective Weeding** Weed control is crucial during the early growth stages. At the 3- to 4-leaf stage, use a high-efficiency herbicide like glyphosate at a rate of 40 ml diluted in water. For broadleaf weeds, combine spraying with manual soil loosening around the plants to improve root aeration and reduce competition for nutrients. 3. **Timely Pest Control** During the flowering period, monitor for pests such as bean borers and aphids. To manage bean borers, apply 50% phoxim EC diluted at 1000 times. For aphid control, use 10% imidacloprid wettable powder mixed at 50 times. In addition, proper drainage and earthing up should be carried out to prevent waterlogging and support plant stability. By following these management practices, farmers can significantly improve the productivity and profitability of fresh edible soybean cultivation. With careful attention to fertilization, weed control, and pest management, this crop can thrive and deliver excellent returns in both quality and quantity.

Orthopedic External Fixator

Orthopedic external fixation system

The screw orthopedic is inserted into the bone near the fracture, and the fracture is fixed with an external fixator assembled by a chuck and a nail rod.

Indications

open fracture, nonunion, closed fracture with extensive soft tissue injury, fracture with multiple trauma, osteotomy and correction.

The use of orthopaedic external fixators is currently a superior fracture fixation technique, filling the gap between cast and internal fixation. At the same time, orthopedic external fixator has the characteristics of simple fixation method, stable, reliable and effective, and does not limit the joint movement, can be early ambulation advantages. It can reduce the time for the operator and is more friendly to the user. The external fixator was used together with the bone traction needle. In terms of the classification of orthopedic external fixators, it is mainly divided into four types: orthofix type external fixation, ilizarov type external fixation, ao synthes type external fixation,combined external fixator and common external fixators.

The external fixators in orthopaedics was used for reduction (shortening and overlapping displacement were corrected first, then lateral and angular displacement were corrected, and finally rotational and separation displacement were corrected; If closed reduction is difficult, open reduction can be considered, but the separation of soft tissue and peeling of periosteum should be minimized.

The selection of the insertion site.According to the anatomical characteristics of the soft tissue at the insertion plane, the important nerves, vessels and tendons should be avoided; The ideal entry point is the part of the bone close to the subcutaneous, in a word, generally choose the skin and bone between the muscle soft tissue is the weakest point into the needle. The installation shall facilitate observation and control of soft tissue damage, and permit any surgery that may be required, such as repair and reconstruction, dressing change, skin grafting, or bone grafting." According to the location of the bone, different diameters of the threaded needle were selected. Removal was performed after completion of late treatment.
