Flowers blossom into flowers, and the group helps the ball. The "variety girl" hydrangea, also known as hydrangea, hydrangea, and I prefer to call it Hydrangea. Hydrangeas, whether they are potted plants or garden plants, are very colorful. The flowers are big and charming, and the plants are graceful... Ziyang blossomed beautifully, and it faded as scheduled. prune From mid-July to early August, the flower buds are dying and sprouting, and it is also the flower bud differentiation period. At this point, it is the best time to trim the hydrangea. If you are to prune till September, there will be no reward for the coming year. So how do you trim the hydrangea? The 1-2 truncates below the stumps will not produce new shoots. The flower buds are all born on the base of the petiole above the ground. So, just leave the upper part of the 2-3 fronds and trim off the rest. In winter, when the leaves fall off, the overall plant type of hydrangea can be re-renovated: The fine branches, weak branchlets, and cross branches are cut off from the roots so as to ensure nutrient guarantee that robust flower buds will flourish in the coming year. In the mid-July to early August trimmed branches can no longer be truncated. Cutting From mid-July to early August, it is both a good time to cut the hydrangea and a good time for cutting. Cut the strong twigs of the year for cuttings (not old plants, old branches cutting roots are very slow), each cutting base needs to be knotted, about 10-20 cm long. Each twig cuts off excess leaves, leaves only 1-2 leaves, and cuts off half of the leaves to reduce the evaporation of water to reduce the cutting burden. The cutting depth is 2/3 of the cutting length. After the cuttings are put into the shade-resistant place, they are often kept moist, and they can take root after about 15 days to 1 month. 1. 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.outdoorsolarcamera.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.
