The advantages of fruit trees planted in the autumn, such as rooting, high survival rate, and sprouting in the following year have been recognized by the vast number of fruit farmers. However, there are still some problems to be paid attention to in autumn.
Do not plant deeply. Autumn planting fruit trees, after the natural leaves, before freezing for the appropriate period. As the saying goes, “Shallow planting trees are prosperous and deep trees are weakâ€. Autumn planting of fruit trees should not be too deep. It is advisable to match the roots of fruit trees with the ground. Root-neck is the junction of the ground and underground parts of the fruit tree, and is the only way to get nutrient up and down the whole tree. The root neck enters dormancy at the latest in the fall and releases dormancy at the earliest in the spring, and is most sensitive to changes in environmental conditions. Therefore, the root neck should not be buried too deep or exposed to the ground. Persimmons, jujubes, chestnuts, big cherries, grapes, etc. are not suitable for conventional autumn planting, and it is best to cultivate in the buds during the sprouting period in the spring.
Immerse water and wrap the membrane before planting. Fruit trees soaked in fresh water for 1 to 2 days before planting can increase survival. Due to the phenomenon of stagnation of northern fruit trees in winter, the fruit trees can be wrapped before the planting to maintain moisture and prevent stripping. It is best to use a 0.004 mm plastic film.
Irrigation after planting
After planting, it must be filled with water in a timely manner. Water should be irrigated once every 7-10 days, and water should be poured before freezing.
Produce the designed circuit board, then paste all the driver ICs, prepare all the corresponding LEDs, and then prepare to start the assembly line to start the operation. The AI vertical machine starts to insert the lights, the DIP starts, and all the LEDs Knit the tape, then put it in the Universal vertical machine, start to insert the LED directly, according to the set procedure, insert the entire LED board.
After all the completed P16 full-color display modules have passed the company's quality management inspection, and there are no problems, the product is put into wave soldering, and then all the LED pin tubes are completely soldered. The environmental protection is used. Lead tin.
All the soldered full-color display modules begin to work on the assembly line. All accessories, such as the angle of the signal line of the line driver, and various power sockets, and the entire light board, if there are any, crooked The oblique LED lamp bead will right and level the LED lamp bead for comprehensive inspection.
The color of the lamp beads of the P16 module can be customized. The module can be used in a single module or in a combination of multiple modules. When multiple modules are used in combination, the positive pole of the power cord between the two modules is connected to the positive pole (red ), the negative pole is connected to the negative pole (black); the signal is connected through the signal line.
