one
Inappropriately targeted
The tree suitable for girdling is a tree with strong callus ability, flowering difficulty, age-incompetent species, and strong growth potential. It must not divide the species and tree vigor.
two
Inappropriate girdling time should be from late May to early June, when fruit bud physiological differentiation begins, premature circumcision, affecting the normal growth of new shoots, circumcision too late (after July), The wounds were difficult to heal in that year, and the branches were easy to die, and the circumcision was too early and too late to promote flowering.
three
Inappropriate area of ​​girdling
The girdling should be carried out in the smooth part of the backbone of the central stem from 15-30 cm or lateral branches, and must not be girdled on the trunk to prevent the extreme weakness of the tree, resulting in adverse consequences such as low yield, poor quality, and short economic life.
four
After ripping irregularly, it must pay attention to aligning and ripping, and it must not be misplaced. The width of the strip must be consistent, and the incision must not be burrs to facilitate wound healing.
Fives
Excessive knife wounds
When circumcision can not be exerted too much force, it is required to cut only the phloem, not to damage the formation layer and xylem, in order to facilitate the healing of the wound, to avoid the formation of a black injury ring in the branches after injury to the xylem, affecting the firmness of the tree skeleton structure.
six
The appropriate width of girdling for stripping the mouth is 1/15-1/10 of the diameter of the stripped part of the stripped part, and the maximum width is not more than 5 mm, rather narrower than wide.
Seven
Multiple girdling can only be circumscribed on the main branch or lateral branch. It can not be girded on both side branches, but also circumcision on its mother branch, and moreover it cannot be accompanied by two or more girdling on one branch at the same time. Road. For trees or branches that are still prosperous after one round of girdling, it is advisable that at least 1/2 of the first circumcision wounds have healed in the beginning of July, and the second 3-5 cm below the last excision Secondary girdling, and the excision should be narrower than the first girdling.
Eight
The amount of peeling is too large. The amount of peeling of each tree should be determined according to its growth potential. It should not exceed 2/3-1/2 of the total number of branches of the whole tree, leaving some branches without girdling, so that the root system can still be obtained. A small amount of photosynthetic products, so as not to excessively weaken the tree vigor, resulting in premature aging trees.
nine
Peel off after application
Some growers are concerned about the infection of rot bacteria in the girdling area. Therefore, some drugs such as Formamide and Aspen are coated on the excision area, resulting in dead trees (branches). The excision wounds should not be randomly coated to facilitate the smooth healing of the wound.
ten
After improper stripping and management, if peeling does not heal within one month, plastic film is used to promote rapid wound healing; after girdling, the management of fertilizer and water in the orchard should be strengthened and sprayed 2-3 times during the growth period. 0.4%-0.5% urea solution and 0.2%-0.4% potassium dihydrogen phosphate to supplement tree nutrients; when the flower formation is large, strict flowering should be carried out during the flowering period the next year so that the tree body can be properly loaded and maintained. Its strong tree potential.
What is a smart bulb WiFi camera? The monitor, which looks like a light bulb, is commonly used for home security monitoring. The shape of the bulb is diverse, but it can not be separated from the combination of nuts. Directly connect the nut to achieve 24-hour continuous monitoring, power off free, 360 degree panoramic monitoring. Smart home bulb WiFi camera with night vision function can also see clear images in the dark night
What is the purpose of smart bulb WiFi camera?
1. The panoramic 360 degree VR monitor can monitor the whole room by installing a light bulb in one room. There is no dead angle and video can be viewed in multiple modes.
2. Smart bulb WiFi camera can be used for lighting. Even though it is a household monitor, its basic lighting functions are well protected. The voice control light on mode and the app manual light on mode are very convenient for operation.
3. Two way voice intercom function. The smart home bulb monitor has its own microphone, which can listen to and play audio. Through calling on the APP, wireless WiFi transmission is directly realized, and then played through the bulb microphone. Its role is to directly communicate with family members, and the other is to intimidate the invasion of illegal elements.
4. As a monitor, it is locally stored in the memory card, plus the backup protection of the cloud disk. Even if someone destroys the camera or even takes away the home surveillance camera, the smart home bulb WiFi camera can still view relevant videos in the cloud disk.
How to use the smart bulb WiFi camera?
Scan the QR code on the mobile phone to download the corresponding APP software, and search the corresponding software name in the app store on the iPhone.
Power on the WiFi camera of the smart home bulb, search for the WiFi hotspot signal sent by the bulb in the phone settings, and click Connect.
Open the mobile phone APP and search the camera online. This process is automatically completed. Just wait.
Configure the local WiFi name in the APP settings, fill in the password, and remote monitoring can be realized after the configuration is successful.
