The removal of rice fields is a technological measure that saves both labor and cost. In addition to improper selection of chemicals or unscientific methods of application, it will directly affect the weeding effect and even cause phytotoxicity. In addition to the selection of rice seedlings in rice field, we must consider factors such as the seedling quality and the depth and depth of planting during rice transplanting. In order to effectively control the damage of rice transplanting field weeds, we should focus on five key measures.
1, according to age and grass, choose safe and efficient herbicides, accurate selection of drug species and application methods. Strictly follow the operating procedures and do not increase or decrease the dosage. The amount of drugs should be accurate, and the high density of weeds should be used for high doses.
2. After planting a living tree, it is necessary to use the medicine in time according to the technical requirements; applying the medicine too early will affect the survival and delivery of the seedlings, and delaying the application of the pesticide will affect the weeding effect. After the rain and when the dew is dry, no pesticide can be applied.
3. Careful site preparation should be done during transplanting to ensure that the flat and flat soil blocks are flat and small enough to be removed. When the pesticide is used, the paddy fields should be kept in shallow water layers. When the water layer is too deep, it should be drained to keep the shallow water layer.
4, after the drug to do a good level of water shortages, to prevent flooding after inundation of rice leaves and cause phytotoxicity.
5. The water layer must be maintained within 5-7 days after spraying, and water should be filled in time for the water leakage field. Ensure that the efficacy of drugs works properly.
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!
