The low-temperature, high-humidity, and low-light environment in front of the greenhouse is not conducive to the growth of vegetables, but it is very suitable for the growth and reproduction of pathogenic bacteria, which also makes the front of the shed a plot with high incidence of vegetable diseases. For example, downy mildew, vine blight, bacterial angular spot disease, brown spot disease... all easily occur in front of the shed and spread from it. So, how to improve the low temperature and high humidity environment in front of the shed so that the vegetables on the front face of the shed can thrive? Dehumidification blocks disease breeding "space" Vegetable farmers have never had a better way to deal with the lowering of the humidity of the front face, but some good practices of vegetable farmers are worth learning from. The front face is equipped with a moisture-retaining film. The ground film is vertically suspended on the front face to prevent moisture. The upper part of the ground film should be connected with steel wire, and the lower part should be compacted with soil to form a relatively closed environment. Use clamps to clamp and level, so that the dew drops on the canopy film can flow down to prevent water accumulation on the water retaining film. The installed windshield film should have a space of 10-20 cm from the shed film, and do not stick to the shed film. The front face is equipped with a water guide. The water guide can be PVC or a waste hose, or it can be a "V"-shaped groove commonly used in farms for drinking water for poultry. Regardless of which type is used, the principle is to collect the dripping water in a centralized manner and then drain it away. For the under-dug greenhouse, curing the front face and covering with a film is the most ideal choice. On the one hand, it reduces the humidity of the front face, and on the other hand prevents the water dripping from the membrane from eroding the soil, causing the front face to collapse and causing unnecessary vegetables. Impact. Before covering the front face, repair and level it, and then cover it with a thin film or black film. This will not only make the water droplets on the front face flow into the soil smoothly, but also prevent the growth of weeds on the front face and become a disease base . In addition, laying crushed straws, such as corn stover, wheat bran, and wheat stalks on the front face, can also prevent the front face from getting too wet. Insulation creates an "environment" suitable for greenhouse vegetables The windshield film on the front face not only reduces the humidity, but also reduces heat loss and increases the temperature in the shed. The layer of non-woven fabric or old straw curtain that is added when the non-woven fabric is added to the shed is covered under the insulation quilt, which can greatly enhance the thermal insulation effect of the front face of the greenhouse. The non-woven fabric is soft and the height should be higher than the front face when used. First, tie the non-woven fabric to the laminating rope, and then put the heat preservation down. The height of the old grass curtain covering the old grass curtain should be lower than the height of the front face of the shed, and it should be set to more than 1/2 of the height of the front face, so that when the roller shutter machine reaches the front face, there is a large drop from the ground. The curtain rod will quickly fall to the bottom of the front face. If it is the same height as the front face, the old grass curtain will easily be overwhelmed or propped up, and it will not be able to keep warm. Setting up a straw reactor The straw reactor can increase the ground temperature, ensure good root growth, and promote healthy plant growth. Replenish light to promote "unobstructed" breathing of vegetables For the under-dug greenhouse, the plants within one or two meters of the front face are less exposed to sunlight. If the nearby sheds are denser, the higher the front neighboring sheds will increase the shade here. Conditional vegetable growers can individually install a certain number of fill-in lights on the front face, and individually "turn on a small stove" for the plants near the front face. Some vegetable farmers increase the light by installing reflective screens near the first column on the front face of the shed or wrapping reflective screens on the columns. The effect is also good.

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.
