Wintering fruit trees should pay attention to antifreeze

In winter, the temperature dropped suddenly, and the overwintering fruit trees were vulnerable to low temperatures, which led to slow growth in the spring. Agro-technical experts reminded the fruit tree growers that they should pay attention to fruit trees to prevent freezing and prevent cold and ensure that the output and quality of the fruit trees will increase in the coming year.

Replenishment, fertilization, and fertilization Winter frosts often cause damage to the buds, young leaves, flower organs, and shoots of fruit trees to varying degrees. In order to restore the tree vigor as soon as possible, fertilizer and water management should be strengthened to supplement the nutrients of the tree and enhance the drought resistance and resistance of the tree vigor. Disease power. After the flower can be applied after the organic, inorganic bio-fertilizer or fruit tree special fertilizer and other compound fertilizers, with the new high-fat film 500 times + Feifan 800 times, pay attention to spray twice, to restore the vigor, improve the tree Resistant.

After applying the pesticide to prevent damage to the trees, the disease resistance is reduced, and the pests and diseases are easily invaded. It is necessary to prepare 1000 times liquid (500 kilograms) of Hushu Grand General's mother liquor in time to insulate the trunks and branches to insulate, disinfect and prevent frost, and prevent wintering. The virus spreads in the tree to reproduce, restores the fruit tree life command system to wake up early, preserves flowers, preserves fruit, and can also mix with various types of pesticides.

Wind-breaking and spring-flowering spring fruit trees often suffer from low temperature, strong winds, and late frost, affecting normal pollination and fruit setting. Before flowering, care should be taken to keep flower buds in proper conditions, and to wait for fruit setting before fruiting. The victims of fruit trees should not be trimmed in the short term. They should adopt methods of late fruit thinning or fruit keeping. They should retain fruits that have not been victimized or suffer light damage, ensure multiple results and produce good results, and recover losses caused by frost.

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!

Parameters of U85:

Mini Laser Distance Sensor,Optical Laser Distance Sensor,Smallest Laser Range Sonsor,Laser Measuring Sensor
