1. Choose cold-resistant, solid-resistant storage and dark green varieties. Seeding with new high-fat membrane before planting (can be mixed with seed coating agent), can avoid underground pests, isolate virus infection, does not affect germination and swelling function, strengthens breathing intensity, improves seed germination rate; chooses loose texture, fertile, Seedlings with deep soil layers, enhanced management of fertilizer and water during seedling period, small water and water pouring, thin fertilizer and diligent application, and cultivation of robust seedlings.
2. Use bio-organic fertilizer before planting and spread evenly. At the same time, quick lime is applied per acre, shallow tillage is carried out, fertilizer, soil and lime are evenly mixed, and then the soil is prepared.
3, timely spraying vegetables and strong stems, so that the plant stems thick, thick leaves, fresh leaves, plants lush, while improving the ability to resist disasters, reduce the amount of pesticides and fertilizers, reduce residual toxicity.
4. In case of low temperature, cover with double or multi-layer film to prevent freezing damage. Uncover the film at noon on sunny days, ventilate and reduce humidity. Before the plants are closed, the water is poured into the water for 2 to 3 times. After the ridge is closed, the urea solution is poured once.

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!
