How to treat loofah "sweet melon"?
My loofah just started to lick the roots, but after a few days, many melons have collapsed. What do you say about this? "Shouguang Gucheng Street Master Zhang asked the reporter. The melon is the customary saying of Shouguang vegetable farmers, which means that the stalks of the loofah are broken and severely broken.
When I came to the shed of Master Zhang, the reporter found that the loofah had just been poured over the water and the ground was very wet. It turns out that the soil in the shed before the flowering is relatively dry. In order to avoid the humidity of the air after the watering, the ground mud is too much and it is not easy to operate. Master Zhang took the first flower and watered it the next day. This is the silk flower. After a large number of melons.
The melon is occurring 2-3 days after the flowering, and the melon has not been lowered before. Vegetable growers who have been planting loofah for many years know that the water before and after the melon must be timely. If the watering is too late before flowering, that is, water is poured and fertilized 1-2 days before the flowering, the water and fertilizer supply is sufficient, and it is easy to cause the melon. After watering the melon, it is too early to water, that is, after the scented flower, the melon will be watered to promote the melon, and it will also cause melon. For the melons caused by watering, the precautionary measure is to prematurely water the flowers before the flowers are piled up, and the melons are poured and then the melons are poured to avoid the supply of water and fertilizer.
In addition to the above reasons, the plant growth is too prosperous and the use of medicinal herbs is also two key reasons for loofah and melon. To guard against melons, we must also pay attention to these two points.
Experienced vegetable growers know that melons occur on root melons, mainly because of the rapid growth of loofah in this period, which is difficult to rapidly transition to reproductive growth. In this regard, before the melon, if the plant grows too prosperous, it should be sprayed once to help the growth of the plant and then carry out the melon.
The use of scorpion medicine is not appropriate. It means that the anthers are smashed into the melons and the hormones are strongly transformed, so that the young and fragile melons are difficult to adapt and break. Therefore, when you spend the flowers, you must not put the anthers on the melons. You should pick up the 2/3 parts of the melons.

How do WiFi Camera Work ?
Monitoring cameras can also be installed without a network, but some functions cannot be used, such as remote monitoring. In order to make it easier for you to understand the knowledge related to the surveillance camera, I will use popular language to popularize science for you.
1: Camera introduction
Camera is an intelligent device that can capture and record video and monitor the environment in real time. It can not only record video, but also detect moving objects, sound, smoke, and even recognize faces.
The advantages of the camera are very obvious. It can help people better monitor the safety of their homes or offices, and help protect the safety of family members or office staff. In addition, it can also provide real-time video monitoring, provide more security guarantees, and help people better grasp the current security situation.
Among them, "intelligent camera" is a new technology in recent years, which can monitor the environment in real time and conduct intelligent identification. The intelligent camera adopts high-definition camera technology, which can clearly capture the on-site images within the monitoring range and conduct real-time monitoring. It can also analyze the captured pictures to identify the designated person or object, thus realizing intelligent monitoring.
In addition, 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, allowing users to view the image of the camera anytime and anywhere, to better protect the security of your home or office.
At present, cameras have been widely used in the security industry to monitor buildings, parks, schools and other places to protect the safety of the people. It can also be used in commercial places to help businesses achieve intelligent management, improve business environment and improve service quality.
2: 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.
