How to promote citrus fruit expansion in autumn
Strengthen fertilization In order to achieve the balance of citrus vegetative growth and reproductive growth, it is necessary to fertilize the trees and coordinate nutrition. For trees with large trees, more fruits, and weak vegetative growth, re-apply strong fruit fertilizer and a reasonable combination of nitrogen, phosphorus, and potassium fertilizers to fully meet the nutrient needs of fruit expansion and new shoot growth. For young trees with less fruit and vigorous growth, apply less fertilizer appropriately, especially control the amount of nitrogen fertilizer to prevent excessive growth and improve quality. Insist on the combination of ground fertilization and foliar fertilization. In the late stage of fruit expansion, spray 0.2% to 0.3% potassium dihydrogen phosphate or compound fertilizer or 20% plant ash extract and 1% superphosphate extract, 0.03% to 0.05% nitric acid. Rare earth can not only promote fruit swelling, but also promote coloring, sweeten and ripen early, improve quality and improve storage durability.
Scientific drought resistance September is the peak period for citrus fruit swelling and autumn shoot growth. Therefore, strengthening drought prevention is the key. Orange orchards with conditions must be irrigated in time; mountain orange orchards should be covered with grass to keep moisture and drought prevention; strengthen cultivating loose soil to protect moisture To prevent soil compaction and reduce water evaporation. Spray water on leaves in dry weather to increase air humidity.
Strengthen the prevention and control of pests and diseases During the swelling period of citrus fruits, the main pests are anthracnose, resin disease, rust ticks, red spiders, scale insects, and fruit suckers. The prevention and control should be strengthened in time to prevent fruit dropping and field disease before harvest, and improve the commodity rate and storability of the fruit.

The foot and ankle locking plate is a special-shaped plate specially developed for calcaneal and ankle fractures, which is in line with the anatomical structure of the calcaneal and ankle joints.
During the postoperative treatment process, it can reduce the stimulation of surrounding tissues and promote bone healing.
The calcaneus is the largest of the seven tarsal bones and is located on the lower back of the foot, forming the heel. Calcaneal fractures are relatively rare, accounting for 1% to 2% of all fractures, but are important because they can lead to long-term disability. The most common mechanism of severe calcaneal fractures is axial loading of the foot after a fall from height. Calcaneal fractures can be classified into extra-articular and intra-articular fractures. Extra-articular fractures are generally easier to assess and treat. Patients with calcaneal fractures often have multiple comorbid injuries, and it is important to consider this possibility when evaluating patients.
The ankle joint is composed of the articular surface of the tibia, the lower end of the fibula, and the talar trochlea, so it is also called the talar calf joint. Ankle fractures, including fractures of the medial malleolus, lateral malleolus, posterior malleolus, or fractures of varying degrees occurring simultaneously, are due to greater violence to the medial and lateral malleolus. At the same time of both ankle fractures, the talus directly impinges posteriorly or impinges on the tibia when displaced by external rotation. Fracture of the posterior malleolus due to the posterior margin.
Foot Mini Locking Plate is composed of 2.7mm series of mini locking plate, covering a variety of plate types, widely used in trauma fixation and orthopedic surgery of the forefoot. Anatomical design of bone plate to reduce the need for shaping.
