Fruit tree spring pruning technology

The following points are mainly made in the pruning process:

One is to choose a good time. After the temperature rises and stabilizes, the sprouts of fruit trees can be clearly recognizable when the leaves buds and flower buds are cut, and they are sheared off before the bud expansion period.

The second is to master the correct method. 1. The fruit trees in full fruit period are trimmed according to the proportion of growing branches and fruiting branches of 3:1, and the resulting mother twigs are trimmed. 2. For older trees with more flower buds, we should keep weak and strong, renew senescence and dense sticks, properly cut short and medium long fruit sticks, and sparsely cut cross-sections of the middle and upper parts of the crown and waste and weak branches. 3, spend less young trees to stay as much as possible flower buds, sparse dense nutrition branches. 4. In addition to the normal short cuts, the branches of the saplings can be long-distributed, but they can also be properly shortened to facilitate the development of shoots.

Micro Laser Distance Sensor

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!
