Apple staged fruit thinning method

Fruit thinning is the second key practice used to regulate the economic yield of apple trees following the initial step of blossom thinning. Its purpose is similar to that of blossom thinning: it involves removing excess fruits that exceed the tree's capacity, ensuring that the tree's fruit production aligns with its nutrient supply and demand. This process helps enhance fruit size, improve fruit shape index, promote better color development, and ensure consistent yields over multiple seasons. Manual fruit thinning typically starts one week after flowering and should be completed within 20 days post-flowering. The process is usually carried out in two stages. The first stage, known as early fruit thinning, occurs 6 to 10 days after flowering. At this time, the focus is on removing dense or crowded fruits within the inflorescence. The second stage, often referred to as "setting fruit," takes place 10 to 20 days after flowering—just before the apples are bagged. During this phase, extra, deformed, small, or misshapen fruits are removed to ensure only the healthiest ones remain. There are several methods for setting fruit, including thinning by branch, by leaf count, or by distance. Thinning by distance is particularly simple and effective. When done this way, one fruit is left every 30 to 50 cm along the unbranched or hanging branches. This method ensures even distribution and avoids over-crowding, which can lead to smaller, lower-quality fruit. Proper timing and technique are essential to maximize the benefits of fruit thinning and support long-term orchard productivity.

Hip Joint

In hip joint replacement surgery, can be broadly divided into two kinds,cemented artificial hip and cementless artificial hip, due to the selection of different materials, the price is also very different.
Generally , the cemented type is suitable for osteoporosis, poor bone conditions, 65 to 70 years of age and older patients. The use of bone cement for artificial hip joints allows for early mobility, which is also suitable for older patients. In addition, elderly patients are generally less active, artificial joint wear is also light, replacement of an artificial joint can be, generally need less revision. The price of bone cement type artificial joint is low.
Cementless type is also known as biological fixation type, suitable for young and middle-aged patients with good bone conditions, such artificial joints have micropores or biological coating materials on the surface, bone can grow into it to achieve the role of fixing artificial joints, so it is often called biological fixation type. Cementless artificial hip joints allow their bones to slowly grow together with the artificial joint to achieve a fixed role.

Total cementless hip system indications

1.The main purpose of total hip replacement is to relieve hip pain,and the second is to improve hip function. The main indication for total hip arthroplasty is hip pain caused by hip lesion over 60 years old,which can not be used for other operations but only for head and neck resection.

2.Replacement surgery may be considered in patients over 45 years of age with subluxation of the hip,traumatic arthritis, pain, or loss of function.Due to the insufficient depth of the acetabulum,the upper margin of the acetabulum is inclined, which affects the stability of the acetabulum cup,and the acetabulum should be deepened or covered.

3.Indications of the need for replacement include hip pain due to loosening of the prosthesis,stem fracture,prosthesis dislocation, manual reduction failure,central dislocation caused by acetabulum wear caused by prosthesis and pain.
