First, autumn Shi base fertilizer
After the rain, the soil is fully wet and then applied to the base fertilizer. The parallel ditch is opened at the drip line on both sides of the tree. The organic fertilizer or bio-organic fertilizer such as Shiyuanlin brand is 3-5 kg, and the ditch cover covers the soil layer 5-10 cm.
Second, plastic trim
It is advisable to use a natural evacuation layered tree type, and the pruning principle is to separate and emphasize. For overlapping, co-existing, cross-competing, and competing branches, the poorer ones are removed, and the diseased branches, dead branches, and weak result branches are cut off. After pruning, the callus and anti-corrosion film should be used in time to protect the wound healing tissue growth, anti-corrosion pathogen infection, anti-soil, rainwater pollution, anti-freeze, anti-shock crack, to reduce nutrient consumption, improve flower quality and fruit set rate.
Third, pest control
In the autumn, spray an anti-insect treatment agent, combine foliar fertilizer, promote flowers and so on. In the dormant period of the deciduous period, spray the tree to protect the generals and completely eliminate the source of the wintering pests.
Fourth, prevent premature defoliation
At the same time of pest control, the drought should be properly irrigated, and the leaf surface should be sprayed with a new high-fat film to prevent leaf virus infection, prevent premature leaf detachment, and affect the normal fruit quality and quality improvement next year.

New product of U85 micro laser distance sensors use highly focused class 2 laser to detect objects or measure distances, and can return a measured value via varieties intface( serial, usb, rs232, rs485, bluetooth etc.). The electronic distance sensor is a very small Laser Distance Sensor, but high resolution up to 1mm and long distance measuring sensor - teachable measuring range of up to 30m. Extremely accurate distance sensing sensors, errors down to ± 1mm. And the mini sensors and measurements support continuous measurement function, great for compact solutions(eg: robots) with the smallest Laser Distance Sensor of the world!
