How to prevent celery soft rot?

The methods to prevent celery soft rot are as follows:

1. Rotation. The soft rot of celery is mainly spread through the soil, etc. It is easy to accumulate a large number of germs in the soil of the heavy soil. Therefore, it should be rotated for more than two years, and a new high-fat film can be sprayed evenly on the ground to keep warm, moisturize, prevent disease and deworm. . Filter plant respiratory impurities, prevent pollution, and inhibit viral infection.

2. Cultivation management. Since soft rot is first invaded from the wound of the plant, plant wounds are one of the important factors in the pathogenesis. For this reason, in various operations such as planting, cultivating, weeding, etc., root damage or wounds should be avoided. The planting should not be too deep, the soil should not be too high, so as to avoid the petiole buried in the soil; timely drainage after the rain; the diseased plants were found to be cleared in time, and the general guards were sprayed for disinfection and sterilization.

3. Chemical control. At the beginning of the disease, new high-fat membranes are sprayed with targeted insecticides, sprayed once every 7 to 10 days, and sprayed continuously for 3 to 5 times to prevent the growth of pathogens and improve the prevention effect.

Mini Led Wall Pack Light

Comparison of the advantages of mini Led Wall Pack Light

As a light-emitting device, the reason why it has attracted much attention is that it is superior to other light-emitting devices. It has the following advantages:

(1) Long working life: led mini wallpack light, as a conductor solid-state light-emitting device, has a longer working life than other light-emitting devices. Its brightness half-life can usually reach 100,000 hours. If LED is used to replace traditional car lights, its lifespan will be much longer than that of the car itself, and it has the characteristics of no need to repair and replace it for life.

(2) Low power consumption: led mini wallpack light is a low-voltage working device, so under the same brightness, the power consumption is small, which can greatly reduce energy consumption. On the contrary, with the development of technology and materials in the future, it will have higher luminous efficiency.

(3) Fast response time: Generally, it can respond within tens of milliseconds (ns), so it is a kind of telling device, which is also beyond the reach of other light sources. The use of LED to make the high-position brake light of the car greatly improves the safety of the car at high speed.

(4) Small size, light weight, and resistance to resistance: This is the inherent characteristic of semiconductor solid-state devices.

(5) Easy dimming, color matching, and high controllability: As a light-emitting device, the brightness can be controlled by the change of the flowing current, and the color change and adjustment can also be realized by the configuration of LEDs with different wavelengths. Therefore, the light source or display screen composed of LED is easy to meet the needs of various applications through electronic control, and it is extremely difficult to be compatible with IC computers. In addition, the application of LED light source is not subject to smell in principle, and it has strong plasticity and can be extended arbitrarily to realize building block assembly. The current large-screen color display is none other than LED.

(6) The light source does not have environmental pollutants such as mercury and lead, and will not pollute the environment. Therefore, it is well-deserved to call LED light sources a "green" light source.
