The cultivation of the prickly pear is often caused by the inadvertent watering, the disease caused by the anthracnose disease and the rot of the ball, and it is a pity that the ornamental value of Jinhu and other rot are bad. So how to prevent it? Generally speaking, if only the star point is rotten, the rotted part can be removed with a little healthy tissue, and the ash can be dried and dried in a cool place (one knife will be used to disinfect the blade once), and the rot will be nested. , the rotten meat should be removed and treated as follows: Method one, using 70% methyl thiophanate wettable powder and other agents directly spread evenly on the decay site to the non-wet, and at the same time, 95% enzymatic soluble powder 2 g to 3 g, mixed in the basin root 0.5 cm to 1 Centimeter thick in the topsoil, then sprinkle with fine soil or sand cover. If the topsoil in the basin is too dry, pour a little water until the powder is moist. Then put it in a cool and dry place, and return to normal management after the skin is dry and the body is harmless. Method 2: After the decayed tissue is removed, the lime is burned and burned, and the side is removed and removed two or three times, and then placed in a cool, ventilated and dry place to dry to dry skin. If it is summer, you can take the hot soil or sand surface on the hot sunny day at the rotten area to see the healthy tissue, remove it after the sprinkle, repeat it two or three times, and finally do not remove it, then put it in a cool, ventilated and dry place until it is dry. Normal management is resumed when the skin is free of disease. Method 3, if the sphere is rotted or even hollow in many places, as long as the middle marrow is healthy, remove the rotten meat after removing the basin, and then repeatedly disinfect the diseased part with 1% copper sulfate or 0.5% potassium permanganate solution, if necessary, soak in disinfection. Rinse in liquid. Or soak the sphere with 50% compound thiophanate-methyl WP 500 times for 2 hours, put it in a cool, ventilated and dry place until it is dry and no longer rot, then re-plant. note: 1. Once the sphere is found to rot, except for the severe rot, the pot soil should be disinfected according to the method 1. 2. Maintain an ambient temperature of 15 ° C or higher, and 25 ° C to 30 ° C is most suitable. 3. Newly planted soil should be mixed with fungicide such as 95% dikesone soluble powder for disinfection, and it should not be watered after planting, and it can be placed in indoors with relative humidity above 60%. 4. For the healthy prickly pear in winter, the temperature should not be lower than 10 °C. The summer spraying should be carried out at noon to prevent the water from squeezing and the ball to rot. Spray 70% thiophanate-methyl WP 1000 times per half month. Dixonone soluble powder 500 times solution, but only one or two times in winter root application. Usually keep the basin soil slightly wet.

Do you want to add a monitoring card to your computer, or do you want to use an embedded hard disk recorder as your monitoring host. The computer monitoring card is more suitable for places that are familiar with computer installation, have professional personnel on duty, and have more functional requirements. Its overall investment is relatively low. Since the monitoring card is installed in the computer, the computer needs to be started 24 hours a day; As for the latter, it does not require professional knowledge, nor does it need to be on duty, and it is relatively simple to operate.

To install security monitoring equipment, it is necessary to determine how many cameras are installed, and the quality and monitoring range of the cameras are affected. It is preferred to determine how many cameras are used for monitoring, and then determine the camera lens monitoring range according to how many cameras are available. Therefore, the distance from the camera to the monitoring point and the monitoring area must be clear. The infrared supply network recommends using the camera of 480 TV line, because it is more in line with that definition.
When installing security monitoring equipment, the third consideration is whether the camera has night vision function. If the monitoring is installed in a dark place, it is necessary to consider using a camera with infrared night vision function.
The security monitoring equipment can be installed via wired or wireless transmission. Although the cost of wireless network is relatively high, it can save a lot of installation trouble and make the monitoring site more beautiful. However, the installation of wireless network monitoring equipment should take into account the environmental problems of security sites. Cement building materials will shorten the wireless transmission distance, and metal building materials may complete the shielding of wireless signals. The infrared transmitter and infrared receiver should be far away from other appliances to avoid interference. Because the price of wireless network is almost twice that of wired transmission monitoring equipment, I suggest using wired transmission installation.
On site monitoring and network monitoring When determining the installation of the monitoring system, you should consider whether you need network functions. That is, if you need to monitor and control the monitoring site on the Internet at any time, you need to select a monitoring host with network functions. Avoid no network transmission function after installation.
A complete security monitoring equipment should at least have three parts: surveillance camera, PTZ and decoder. The following are their installation methods:
