Improve fertilization methods and strengthen soil management. Application of bio-organic fertilizer, compound fertilizer, whether it is a ring or radial digging trenches, first, more radial ravine (8-10); Second, long-ring ditch to be long; Third, deep and 30 cm deep . Fertilizers are widely exposed to the roots of fruit trees. For soil management, it is necessary to insist that the whole orchard be done once a year in the spring to keep the live soil well ventilated and prevent the root system from being introduced to the surface. Apply base fertilizer in autumn to increase storage and nutrition. It is necessary to fully understand that fruit trees have adequate nutrients for storage in winter, which is both the basis for ensuring the robustness of the tree and the key to ensuring the high yield and quality of fruit in the following year. Harvested fruit trees such as cherries, apricots, peaches, plums, walnuts, grapes, early and mid ripe pears, apples, etc., will be completed in September. Chestnut and late-maturing varieties of apples, pears, peaches and other fruit trees, after harvesting in October, must grab time to apply base fertilizer, good sensation, after the fall can also bring fruit basal. Dredge the drainage system to prevent water accumulation in the orchard. In the orchard through the orchard, increase the height of 15-20 cm around the trunk to form a dorsal shape to prevent stagnant water after the heavy rain. The rows of fruit trees are lower than the 15-20 cm canopy below the canopy, and the dry days can be watered smoothly. After heavy rain, they can be drained smoothly. Strengthen soil improvement and scientifically replant young trees. If the roots of rotted roots are dead trees, they must dig large holes and fill the top and bottom with organic matter such as topsoil, sand and weeds, and straw to create a loose layer of living soil. In the fruit trees where the roots were dead, many harmful germs remained in the ground, and small fruit trees were planted. First, it was not easy to survive. Second, even if they survived, they did not grow. Disclaimer: Some articles in this website have been transferred from the Internet.

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 PTZ Solar Camera,Solar CCTV PTZ Camera,Home Security Outdoor Camera,Security Outdoor Solar Camera,Solar Camera Shenzhen Fuvision Electronics Co., Ltd. , https://www.outdoorsolarcameras.com

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
The method to solve the rot of fruit trees
Change the fertilization consciousness and get out of the error of chemical fertilizers. Advocate the application of organic fertilizer; in particular, the application of high-quality microbial fertilizers. If nitrogen, phosphorus, and potassium are insufficient, nitro compound fertilizer can be used as a supplement; vigorously promote the use of defoliation, weeds, and straw of fruit trees buried underground after pulverization to improve soil aeration.
