Watermelon inverted vine period: When the melon vine grows to 5~6 true leaves.

Method of pouring vines: Put a piece of mud or soil on the base of the vine that is opposite to the direction of the main vine; force the vine to climb to the ground in the direction of extension.

2, Li Teng:

The vine period: After the vine. In the long period of melon, the vines are once every 2~3 days.

Method of vines: straighten the vines, make the vines evenly distributed on the surface of the vines, and put the vines that extend out of the stalks back into the sputum and fix them.

3, pressure vine:

The role of pressing vines: positioning the melon vines to promote the growth of adventitious roots and expanding the nutrient absorption area of ​​the plants.

During the pressing period: when the vine grows to 40~50 cm, it starts to press the vine.

Method of pressing the vine: press the vine with the soil, and then press it every 4~5 knots, and press 3~5 times. However, it should be noted that the front and rear sections of the melon can not be pressed, and the arid areas and the heavier sandy soil should be dark pressed (that is, a section of vines buried in the soil), and the rainy areas and the more viscous melon should be used. Pressure (pressed on the melon vine with mud); the watermelon land is usually not pressed. The vine should be carried out on a sunny afternoon. On a rainy day and a sunny morning, the water content of the vine is large. It is generally not suitable to press the vine to prevent the vine from being too brittle and broken.

4, cut the rattan:

The role of watermelon vines: adjust the coordination of vegetative growth and reproductive growth of watermelon plants.

The period of cutting the vine: generally from late June to early July.

Method of cutting vines: There are two ways to use the vines. One is the single-vine type, that is, all the vines are cut off, leaving only the main vine. The second is the double-vine or the three-vine type, that is, one or two thick vines on the third and fifth quarters of the main vine and the main vine, and the remaining vines are all cut off. Which method of cutting the vine is adopted should be based on factors such as variety characteristics, planting density, soil fertility, and fertilization level. For the varieties with high planting density, high soil fertility, large amount of fertilization and strong branching ability, single-vine-type vines should be used, otherwise, double-vine or three-vine vines can be used. Early-maturing watermelons generally only leave one vine.

5, stay melon:

Period of staying in the melon: Generally, the second or third female flower on the main vine is left.

Method of staying in melon: large-scale melon seeds, cultivated densely, and strive for early-maturing and high-yield watermelons, leaving only one melon per plant; small melon varieties, each plant can leave 2~3 melons, but it is not suitable to stay at the same time. Excessive melons affect precocious puberty, and the two watermelons are not large. When two female flowers are opened on one vine at the same time, one should be removed, and the female flower squash with large shape and thick flower stalk can be selected, and the two flowers can be removed into small melons. Melon, keep its strong melon.

Installation and use should be relatively simple, mainly reflected in two aspects: one is that the installation and debugging of the camera itself should be relatively simple, and the other is that the operation of the client should be relatively easy to get started. Regarding the installation location and height, we have chosen a height of about 3 meters as a suitable installation location. This not only ensures good visibility, but also prevents the camera from being easily damaged by people
Bad.
3. To support multiple recording storage modes, not only local storage but also cloud storage should be supported.
Four. In the process of purchasing cameras, it is best not to be greedy for cheap prices and not simply pursue cheap prices. It is necessary to comprehensively consider factors such as the stability and clarity of the camera head. Whether the operation of the camera head is stable is determined by the 40 modules in the middle
The clarity is determined by the image sensor.
5. Because the 40 surveillance camera belongs to an all-in-one machine, the product structure is relatively simple, and there are no complex circuits, so it is very stable during use
