Fruit base fertilizer is generally divided into autumn, winter and spring planting, that is, from the fruit harvest to the spring before the spring of this time. Practice has proved that the best results are in autumn, especially for deciduous fruit trees. This is because the higher temperature in the autumn and the strong microbial activity in the soil are conducive to the decomposition of fertilizers and the absorption of nutrients by the fruit trees, thereby enhancing the functions of the leaves and synthesizing more organic nutrients, which will have a good effect on germination, shoots, and fruit setting in the coming spring. At the same time, it can also enhance the cold resistance of the tree, which is conducive to safe wintering. However, the following points should be mastered during the autumn fertilization.
The fertilizers were mainly organic fertilizers and slow-acting fertilizers, such as manure fertilizer, soil miscellaneous fertilizer, cake fertilizer, and grass ash, etc., and appropriate combinations of available N, P, and K fertilizers. The application amount of organic fertilizer should account for more than 90% of the total annual fertilization.
The amount of fertilizer used should be based on the size of the fruit, nutritional status, and the number of fruits. Each plant applies 35-50 kg of organic fertilizer, 1-1.5 kg of superphosphate and 0.4-0.5 kg of urea.
The method was combined with orchard ploughing, using radial furrows or annular furrows. Fertilization depth 40-50 cm. The apples and pears were applied slightly deeper, and the peaches and vines were slightly shallower. Cover with soil after fertilization.
After watering and fertilizing, pouring 1-2 times permeated water can not only make the fertilizer have enough water to ferment and decompose with rapid rot, but also can make the fruit trees not dry during the autumn season. After watering, it can also be covered with crop straws, weeds and other materials.

So what about the advantages of the AHD Four in One CCTV Kit?
AHD Four in One CCTV Kit is the combination of the AHD Four in One Cameras and the Digital Video Recorder. Let me introduce you the 2 parts respectively.
The AHD Four in One Camera, also called the Analog High Definition Camera, one type of the analog camera, contains 4 video formats, and they are AHD,TVI,CVI,and CVBS respectively. The AHD Four in One Camera can transmit the ultra-long distant (500 meters) high-definition analog signal(resolution above 720P is High Definition, also called the HD ) via the ordinary video cable or the 75-5 coaxial cable.The AHD Four in One Camera adopts the advanced Y/C signal separation and analog filtering technology, which can effectively reduce color noise in the high-frequency area and improve the image restoration. Besides, compared with the traditional analog high-definition camera, the image resolution of the AHD Four in One Camera has a great improvement and the highest definition can reach up to the equal level to the network HD 1080P.
The Digital Video Recorder, also called the DVR, is the video storage device(a computer system for image storage and processing) via the hard disk recording. The Digital Video Recorder has the functions of long-term image recording, voice recording, remote monitoring and control of images/voices. In terms of the image processing, image storage, retrieval, backup, network transmission, and remote control, the Digital Video Recorder is the far superior to the analog monitoring equipment because of the adoption of the digital recording technology.
The Digital Video Recorder represents the developing direction of the TV monitoring system, and it is also the first choice for the TV monitoring system in this market.
What about the disadvantages for the AHD Four in One CCTV kit?
The AHD Four in One CCTV Kit is wired and it is not so convienient as the Wireless CCTV Kit in some applications, but the AHD Four in One CCTV Kit is stable and cheap in some degree.
