Rice smut disease occurs in all rice areas. The diseased rice ear, the empty rate increased, the 1000-grain weight decreased, the broken rice increased, affecting the yield (general production 5% -10%) and quality, a large number of people have a certain impact on human health. Symptoms of rice were mainly susceptible to disease at the heading and flowering stage, and the pathogens affected the upper grain of the ear. Onset granules revealed a yellowish-green, small sclerotia at the joints of the glume. The sclerotia encased the whole glume after swelling. The sclerotium was dark green and had a smooth surface. Finally, it was cracked and black-green powder was scattered. Incidence conditions (1) in the rice break, heading, flowering period of rain and sunshine, high relative humidity is very conducive to the incidence of rice smut disease. The bacteria developed well at a temperature of 24-32°C, and the optimum temperature was 28°C. Below 12°C, no growth occurs above 36°C. (2) The incidence of different rice varieties varies greatly. Generally, spike-type or late-maturing varieties are more susceptible to disease incidence, while those with early spike-type spikes have a lower incidence. (3) The incidence of different fertilization methods is different. Under the same amount of fertilization, the condition is aggravated with the increase of the amount of panicle fertilizer. In addition, partial application of nitrogen fertilizer, deep-water irrigation, field water layer dry too late after the onset of weight. Control measures (1) Choose disease-resistant varieties and establish disease-free seed fields. (2) Improve the cultivation measures, make reasonable fertilization, increase phosphorus and potassium fertilizers, prevent late application of nitrogen fertilizer, excessive, excessive panicle fertilizer, water layer too deep. Promote sparse planting, seedling growth, and improve ventilation and light transmission conditions. Do a good job in autumn, and bury the pathogen in the soil. (3) Seed disinfection with 50% carbendazim 1000 times soaking for 48-72 hours. In the 7-10 days before rice heading, with 6% meloxone powder 1.5-2 kg per mu or 150 g DT fungicide, 50 kg water spray, the control effect is very good.
Foot And Ankle Locking Plate
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.
