Why is the shed rock ginger frequently suffering from bacterial diseases?

“Recently, the bacterial disease of ginger planted in my arch shed has been serious, but the ginger planted in the open air has suffered less. You have to look at what causes this.” said Wang Wang, a farmer in Mingdu Town, Pingdu City, told reporters. . At the same time, when the reporter interviewed Dongxia Township in Qingzhou City, many vegetable farmers also reported that the occurrence of bacterial diseases in the arched shed ginger was heavier.
Through investigations, it was found that when many vegetable growers planted ginger in the shed, because the ginger sprouts unevenly, the vigorously grown ginger has begun to enter the “three strands” stage, and some of the ginger’s first ginger buds also grow less. As a result, vegetable growers promoted the rapid growth of ginger shoots that had just grown by using a method that promoted temperature and promoted growth. When the temperature in the tent reached about 40°C, it had not been cooled. When reporters asked the vegetable farmers why the temperature in the shed was so high, many vegetable farmers told reporters that during the day, the temperature in the shed was much higher than the ground temperature, because the water evaporates quickly, the watering of the vegetable farmers is frequent, and the soil moisture is large. When the temperature in the arch shed reaches about 40°C, the temperature of the surface is about 30°C, and the temperature of the soil where the root grows is less than 25°C. Therefore, the elevation of the temperature is required to increase the temperature of the ground and promote ginger. The growth of roots, which is precisely this kind of management method, leads to improper control of the environment inside the arch shed, which causes a high-temperature and high-humidity environment in the shed, resulting in a serious bacterial disease of ginger.
Without ventilation, the temperature inside the shed is high and the humidity is high. Although it will be beneficial to the elevation of the ground temperature and promote the growth of newly grown ginger, it is not conducive to the growth of the grown ginger seedlings, which will not only cause the growth of ginger stems. It is slender, and the resistance is reduced, and it is easy to make the growing point injured at high temperature, thus providing conditions for the bacteria to invade the ginger under hot and humid conditions, resulting in serious bacterial diseases. In the prevention and treatment of bacterial diseases, vegetable farmers only paid attention to drug control, but they did not create suitable environmental conditions for the growth of ginger. This is precisely why the prevention and control effects of the vegetable farmers are still poor after preventive treatment.
Studies have shown that ginger is most suitable for growth at temperatures of 20-28°C, and plants are robust and resistant to disease. Therefore, Jiangnong should control the temperature in the shed below 28°C by releasing the air in time and covering the shade net or using a cooling agent. It seems that ginger sprouts grow slowly, but the ginger shoots grow thick. At the same time, after the hot and humid gas in the shed is removed, the temperature in the shed is low, and no roasted seedling phenomenon will occur, which is also not conducive to the bacterial disease invading the ginger. In this way, vegetable growers can only receive good control effects when they use Yezizole, DT, agricultural streptomycin or other copper preparations to prevent bacterial diseases.

Dust removal plays an important role in the treatment of air pollution. With the continuous development of industry, the quantity of particulate pollutants discharged is increasing, the concentration of dust in the atmosphere is increasing, and the dust is more and more harmful to people's living environment and human health. Higher requirements for the performance and reliability of dust removal equipment are put forward.

 The traditional dust collector has been difficult to meet the requirements of high standard discharge and superior economic performance. The dust collector device is divided into mechanical dedusting device, electric dust precipitator, wet dedusting device and filter dust-removing device.

 With the rapid development of energy and chemical industry and the deterioration of environment, a higher requirement for liquid cleanliness is put forward, and the petrochemical filtration device will be applied more widely in this field. The separation of solid impurity particles and the recovery of adsorbent and catalyst in gas phase and liquid phase in energy chemical industry. By filtering the solid impurity in the material to prevent the impurity particles entering into the device, the equipment, the pipe fittings are damaged or clogged, so as to ensure that the production medium meets the requirements of the process design and the normal and stable operation of the production device. Protect the safe operation and life cycle of the production plant.

 The filter device can be divided into two types according to its structure: pipeline filter device and device filter device. It can be divided into: sulfur recovery and filtration unit (rich and poor liquid filter device, amine liquid filter unit, solvent collection filter unit,) hydrofining filter unit, hydrogen production filter unit, hydrocracking filter unit, catalytic filter unit and so on.
