Saying that grapes are fertilized and watered

Watering

The sprouting stage is watered before the grapes are unearthed and sprouted. In spring drought-scarce areas, it is also necessary to fill once with water to meet the needs of sprouting grapes.

In the early flowering period before flowering, water is poured once every 10 days before and after flowering. Before flowering, it is suggested that the use of water-soluble fertilizers can be quickly absorbed by the roots, which has a significant effect on promoting the rapid growth of inflorescences, ovary, pollen, and improving the pollination effect and fruit setting rate.

During the berry period, when the berry grows to the size of the bean, the new shoot also grows vigorously. At this time, the temperature keeps rising, and the leaf water evaporates more and more, requiring nutrients and moisture. Therefore, in late June, it is necessary to combine the application of fruit fertilizer to stimulate fruit and water. When there is little rain at this stage, water should be poured every 7-8 days to meet the needs of new shoots and berry growth.

During the berry expansion period before berry ripening, the berry ripening water is applied once in combination with fertilization to supplement the lack of moisture in the late growth period of the grape, increase the yield and quality of the grape, and promote ripening of the ear.

Fertilizer

Precipitating fertilizer is usually applied before the grapes are sprouted. This time the main nitrogen fertilizers are used to promote germination, leaves are thick, and inflorescences are large and strong. If the tree vigor is too prosperous and the spring is not very dry, this fertilizer can be saved, so as not to cause new shooters. In particular, the Jufeng series of varieties are sensitive to nitrogenous fertilizers. If there is sufficient base fertilizer in the autumn, it is not necessary to top-dress fertilizers.

After the large-sized fertilizer is set in the grapes, the fruit is like a green bean. The fertilizer is dominated by nitrogen and both phosphorus and potash fertilizers are applied. Can be applied to high-nitrogen, low-phosphorus and low-potassium water-soluble fertilizers, and if necessary, add urea and other nitrogen fertilizers. This time, the amount of fertilizer should be large, which can account for about 50% of the amount of chemical fertilizer applied throughout the year.

The ripening fertilizer is divided into two parts. 20-30 days before maturity, apply high-potassium and low-nitrogen water-soluble fertilizer. This time, the proportion of nitrogen and potassium is 1:3. In other words, if the nitrogen fertilizer is 15%, then the potassium content must be 45% in order to achieve the expansion and coloring. , increase sugar content, disease resistance, increase production purposes. When the berry begins to soften and is not yet colored, it is applied once more.

Wireless Security Camera

The Network CCTV Wireless Security Camera

Compared with wired cameras, wireless security cameras are less invasive to your home, so they are easier and faster to set up. No need to drill through walls or ceilings. Wireless cameras are also more flexible than wired systems because they are not as constrained as wired systems.

The biggest disadvantage of a wireless Camera System is that it is completely dependent on the strength of your Wi-Fi connection. Any interruption or weak signal can mean that you may lose connection to the system, resulting in the loss of the film, which can be critical

Working principle of camera
The working principle of the camera is to reflect the light to the sensor, convert the signal captured by the sensor into a digital signal, and finally send it to the computer to display the image. Then the camera can capture the static and dynamic images in the picture.
The sensor of the camera is the most important part. It can capture light and convert it into electrical signals. There are many types of sensors, the most common are CCD and CMOS sensors, which can be used to capture images.
The internal circuit of the camera will convert the signal captured by the sensor into a digital signal and send it to the computer. The computer uses these signals to display images, or it can save images to the hard disk drive.
If the camera is not connected to the network, it will not be able to achieve real-time monitoring, but the camera will still work and save the pictures and videos taken. If we need to view, we can only remove the memory for viewing.

The smart camera can also support remote monitoring. You can remotely view the real-time image of the camera through your mobile phone or computer. Users can view the image of the camera anytime, anywhere, to better protect the security of your home or office.
