The second is to adopt shading and coverage. The shed and the small arch shed can be covered with a shade net to cool down the shade, especially when the summer and autumn vegetables are raised, which can reduce the light intensity and water evaporation. The mountain vegetables can be covered with weeds, straws, etc. in situ, and the thickness is 10-20 cm, which is both moisturizing and cooling. The third is water-saving irrigation. Laying spray (drip) irrigation facilities for drip irrigation can directly transport water to the vicinity of crop roots, which is very suitable for solanaceous fruits and melons. The utilization rate of water is over 90%, which is more than double that of furrow irrigation and flood irrigation. . Sprinkler irrigation is suitable for the production of leafy vegetables such as small green vegetables and Chinese cabbage, and can also be used for vegetable seedlings, saving water and labor and reducing diseases. The fourth is to use a variety of heat resistance. Such as "premature 5", "anti-heat 605" green vegetables, "short leaf 13" radish, cowpea and other varieties.

Considering the limitation of storage space and storage cost, as well as the fact that video recording in public places such as residential areas is a prerequisite for multi slot and a certain degree of clarity, video recording is generally deleted once a week or so. 15 days for general entertainment venues, 26 days for financial industry, and 3 months to half a year for banks, depending on the current venue regulations Doorbell Camera,360 Degree Camera, Night Vision Security Camera, Security IP Camera Shenzhen Fuvision Electronics Co., Ltd. , https://www.outdoorsolarcameras.com
2. The length of the storage time of the monitoring video is generally related to the following points: the capacity of the host's hard disk. Generally, a camera needs about 0.3G-0.5G of hard disk capacity for 24 hours of continuous video recording. Different systems have different parameters, the minimum is 0.15G/24 hours;
3. The number of cameras. The more cameras, the more capacity required. Also, the selection of the resolution and picture quality of the recorded picture will also affect the capacity required for video storage;
4. The video recording mode will also affect the space required for storage. The video recording mode is generally divided into [Mobile Video Recording] and [Continuous Video Recording]. The former means that the host starts to record when a moving object passes through the monitoring range, and does not record at other times. This can reduce the storage space required for video recording; On the contrary, continuous video recording is 24-hour continuous video recording.
Selection of vegetables with strong heat resistance
First, timely and appropriate amount of watering irrigation. To properly arrange the irrigation time, water should be poured in the morning, evening or night to avoid watering in the afternoon high temperature and improve the utilization efficiency of soil water in the field. When watering, you can use hole pouring, furrow irrigation or drip irrigation, and do not flood the water.
