Do a good job in four aspects of fruit chapped
From a seasonal point of view, the April-May and October-November periods of each year are in the period of fruit enlargement, and clefts occur due to four factors, such as severe temperature changes, condensation on the surface of the fruit, sudden air release, and unstable watering. Therefore, it is recommended that anti-cracking work be done in these four areas. one. Prevents condensation on the fruit surface. The moisture that evaporates at night mostly condenses on the surface of fruits, leaves, etc., and the temperature of the shed rapidly increases after dawn, and the surface temperature of the fruits is uneven, resulting in chapped cracks. In order to reduce condensation, it is critical to reduce the air humidity in the shed. In the absence of plastic film coverage, it is recommended to use straw and rice husk to reduce soil evaporation and absorb water vapor in the air to reduce condensation on the fruit surface. two. Divide the air several times. When dew condensation occurs on the surface of the fruit, the sudden release of the wind will inevitably lead to cracking of the fruit, which is particularly evident in the management of cucumbers. Therefore, when the air is discharged several times, the moisture in the booth is released without causing a sudden drop in the temperature in the booth. At the same time, in order to avoid cold wind blowing directly on the fruit surface, a windshield film needs to be installed under the air outlet. Conditional vegetable farmers can set up a low number of insect nets on the air outlet to break the air into the shed, and also effectively avoid cold wind. Straight blow. three. Steady watering. Watering by the number of days is the cause of fruit splitting. For example, in the fruit enlargement period, the deep soil is not dry after many days of watering, which causes the internal nutrients of the fruit to run slowly. After watering suddenly, the inside of the fruit is rapidly filled with water and swells, and the peel cannot bear. The internal pressure will split. Therefore, watering should be determined based on the soil moisture, and the general control is about 50-70%. four. Foliar fertilizer to make up in advance. Everyone knows that boron and calcium are sufficient to prevent chapped cracks, and it is too late to supplement when chapped. Therefore, the foliar fertilizer should be supplemented as early as possible. For example, boron-calcium fertilizer can be added when the fruit bean size reaches the quail egg size. Of course, some foliar fertilizers have a certain effect on the prevention of fruit splitting. For example, functional foliar fertilizers containing seaweed essence, amino acids, and enzyme substances can promote cell resistance and flexibility of fruits and leaves.
The Wireless CCTV Kit / Wireless CCTV Kits/ CCTV Kits Wireless/ CCTV Wireless NVR Kit/ Wireless CCTV Kit Outdoor/ wifi CCTV Kit is the combination of the Network Camera and the Network Video Recorder. Let me introduce you the Network Camera and the Digital Video Recorder respectively.

The Network Camera, also called the WEBCAM, WEB CAMERA, or IPC, is the new generation which combines the traditional camera and the network technology. And the Network Camera can normal do the monitoring function with the help of the standard web browser such as the Microsoft IE or Netscape. Besides, the Network Camera also has the built-in digital compression controller and a WEB-based operating system, which makes the compressed and encrypted video data delievered to the final user via the local area network, internet or wireless network. Then the remote user can visit the Network Camera via the standard web browser on PC according to the IP address of the Network and then monitor the on-site video, edit and store the image data, and can even control the camera such as adjust the PTZ and lens of the Network Camera to monitor the target area in all directions. Very convenient, isn't it?
The Network Video Recorder, Also called the NVR, is the corresponding video recording device to the Network Camera, the video capture device. The Network Video Recorder can receive the digital video stream transmitted by the Network Camera via the network to store, manage, and then to realize the advantages of the distributed architecture brought by the network. Simply speaking, the user can watch, browse, play back, manage, store several cameras at the same time and would never worry about the complicated software installation because the computer hardware would not be a limitation for the operation of the wireless CCTV kit.
What is the advantage of the Wireless CCTV Kit?
As the web technology grows so fast, the function of the Wireless CCTV Kit also becomes more and more powerful. The Wireless CCTV Kit has no limitation from the cables so its setup will be easy and its usage is also very simple. Furthermore, the resolution of the Wireless CCTV kit is also wonderful because of its image dealing way.
As time goes by, the Wireless CCTV Kit is more widely applied to all kinds of fields and it would be a good choice for us to choose the Wireless CCTV kit in the terms of its powerful function and convenience.
