What issues should be paid attention to when we close the herbicide on corn?

One is to relieve the herbicide's mobility in the soil. Herbicides that are not easily taken away by water and are easily adsorbed by soil have a good weed control effect and are not likely to harm crop seeds. Second, we must master the herbicide control targets. For example, acetochlor is effective against grassy weeds, while atrazine has a good effect on broadleaf weeds. Therefore, the two herbicides can be mixed and then subjected to a closed treatment. Third, we must strongly adjust the quality of the ground. Good soil preparation has a great influence on the efficacy of pesticides. The evenness of land helps to evenly distribute and completely cover the herbicide on the surface of the soil. In the Huang-Huai-Hai area, corn is mostly used for pasture-free tillage. Due to the influence of wheat stubble, the use of closed herbicides has poor efficacy. Fourth, the amount of herbicide should be determined according to the soil texture, organic matter content, and public opinion. Loamy soil or clay soil with high organic matter content and small soil particles has strong adsorption ability to herbicides, and can be used to increase the amount. On the contrary, sand soil with low organic matter content has poor adsorption to herbicides and should be appropriately reduced in dosage.

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!
