Preventing soil erosion For slope or sandy orchards, grass root vegetation can be used to increase soil fixing capacity, which can effectively prevent and reduce soil erosion and nutrient loss.
Compared with clear farming orchards, the organic content of raw grass orchards increases year by year. The longer the time of planting grass, the higher the organic content.
Adjusting the soil temperature to warm up in winter, warm up in early spring, and cool down in summer heat can provide a comfortable environment for the growth of fruit tree roots.
Adjusting the soil moisture orchard grass can improve the utilization rate of water by fruit trees. Moisture retention in the dry season increases the soil water volume. In the rainy season, grass is used to absorb excess water, which effectively maintains the demand for water in the growing season of fruit trees.
Improve the utilization of nutrients in the soil. The elements such as nitrogen, phosphorus, and potassium in the soil are absorbed and transformed by grass, which can provide convenient conditions for the orchard root absorption.
Increasing the number of natural enemies of pests and changing the orchard's microclimate orchard grass can use natural enemies to prevent pests, reduce the number of medications, and reduce pesticide residues.
In the choice of grass species, there are many types to choose from, here are the following two recommended for everyone.
Old rapeseed. The root system is developed, the leaves and stems are thick, and the water storage is large. The stems and leaves after cutting are particularly prone to rot and ripening. It is a very good organic fertilizer, and the underground rhizomes will also rot quickly within a month, forming a space in the root system. Deepen the roots of the tree. It can be sown in May and September every year, with 0.25 kg of seeds per mu. When the rape grows to 30 centimeters high, when it is bolted, the buds are converged, and the flowers are not blooming, they are promptly cut and covered in situ.
White clover. Leguminous perennial herb, resistant to trampling. Strong regenerative ability, short main roots, well developed lateral roots, multiple rhizobia on the roots, strong nitrogen fixation ability, can effectively inhibit the growth of weeds after sprouting, can be sown every spring and autumn, 0.5-1 kg per mu, suitable for shallow sowing Mowing 2 ~ 4 times according to the growth of the grass, leaving 3 ~ 6 cm of stubble when cutting, the cut grass is covered under the tree tray, and after 4 years, use autumn tillage to deepen the fertilizer.

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.
