2. Rotate with non-host crops such as corn, millet and sweet potatoes.
3. When sowing, farm manure, potash fertilizer, phosphate fertilizer, etc. are added.
4. Seed cream granules when sowing, so that the root absorption of soybean can prevent root infection.
5. Before sowing, 35% metalaxyl powder with a seed weight of 0.3% was used for dressing.
6. Strengthen field management, timely deep plowing and cultivating soil and weeding, remove water after rain and prevent excessive humidity.
7. The diseased plants were found to be set aside in time to completely remove the diseased plant debris, and to disinfect the diseased planting hole and the surrounding lime.
8. After the occurrence of the disease, it is difficult to cure and it should be mainly prevention. 40% of root rot may be used for prevention, 400 times of 70% thiophanate-methyl wettable powder, or 600 times of 58% wet powder, 50% of 50% carbendazim WP. Liquid, or 75% chlorothalonil wettable powder 600 times, or 77% to kill the wettable powder 600 times, or 64% antivirus WP 900 times, any of the above pesticides plus amino acids (Soybean Health Spleen or three days of green, etc.) liquid fertilizer 600 times, add 500 times the fulvic acid solution, plus 1000 times the rooting powder spraying. Spray once every 7 days, spraying 2-3 times in succession, alternating use, spraying the main stem base of the plant. If you use the above liquid irrigation plant roots, the effect is better.
IT02S, is JRT new product in the early 2019, which is a single-point LiDAR sensor, also called tof distance sensor. With a micro size of 46x17x7mm, customers can widely use in many Laser Measurement Solutions. The lidar distance sensor can measure 12m short-range with high frequency up to 100hz. It's great for Unmanned Aerial Systems. If you need us send you data sheet and spec for this products, offering sample as well, pls tell us, thank you.
