Control method of broad bean root rot
First, the implementation of rotation: Vicia faba root rot bacteria narrow host range, the implementation of beans, wheat, rape, etc. more than 3 years of rotation, the effect is good. However, it should not be rotated with legumes. Second, to strengthen the field planning and management: Select Gaoshao drainage blocks, sowing as much as possible to avoid the rainy time; irrigation speeding irrigation speed, to prevent the soil too dry and wet. Third, increase the application of phosphorus and potassium fertilizers, promote plant growth and robustness, improve disease resistance, apply adequate maturity of organic fertilizer, should not use the diseased plants, after the harvest clean the pastoral; Fourth, the seed treatment: before the broadcast with the enemy evenly pine seed dressing 10 hours; or with 50% carbendazim WP 700 times liquid soaking for 10 minutes. Fifth, soil disinfection, soil disinfectant should be mixed with fine soil in the evening, not watered spray, to avoid injury.
Long distance LiDAR sensor series are particularly easy to communication thanks to their fixed connector, which can be plugged it up and off by yourself. Voltage is wider from 8v before to 36v. Low power consumption feature makes it beceome a very competitive, high performance-price ratio, long range Laser Distance Sensor.
