Four points of autumn management of persimmon trees

First, to apply base fertilizer In late September, persimmon fruit harvest, early October is the best time for fertilization. The specific fertilization amount depends on the strength of the tree, the size of the canopy, the yield, and the level of soil fertility. In general, 100 kg of organic fertilizer, 1 kg of diammonium phosphate, and 1 kg of potassium sulfate were applied to each plant, and open shoots were made to furrow, and the ditch depth was 30 cm for fertilization.

Second, the protection of leaves from the persimmon fruit harvest before leaves fall off, the leaves still have strong light and role and transpiration. Spray 3% urea solution on the foliage. It can improve the photosynthesis ability of leaves and facilitate the nutrient storage of the tree. For the flowering results in the coming year, the growth of new shoots has a promoting effect.

Third, pruning leaves after defoliating pests and branches, dead branches, overlapping branches, thin branches, leggy branches and so on. Other branches are appropriately shortened and retracted. For the branches of the results of the year, 2-3 shoots were left short at the base. The old branches that are too long and the large branches of the aging tree are shortened and cut off to have new branches and promote new branches.

IV. Pest Control Clear the weeds, fallen leaves, residual Shidi, pests and branches in the park, and burn them centrally to reduce the sources of transmission. Deep plowing should be combined with fertilization at the same time. The trees were painted white, water 100, quicklime 30, salt 2, sulfur 0.5, and animal oil 0.5 were used for whitening to prevent pest invasion and freezing damage.

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!
