Seed germination test cannot be ignored

Good seed germination tests are the key to selecting the seeds, ensuring the emergence of complete seedlings and ensuring the success of the harvest. In the spring plowing last year, I ignored this point before planting land. The expensive maize seeds that were bought back with a lot of money were planted in three mu rations without germination tests. As a result, the emergence rate was only 50%. In the "destroyed" era, when the corn seed was used, it also caused a loss of production due to mistakes in farming time. There are many similar cases in our area and lessons are profound. At the time of preparation for cultivation, the farmers should be reminded not to neglect the seed germination test to ensure that the improved varieties will be incorporated into the soil and the seedlings will be able to grow and increase their income.

Small 2D LiDAR Sensor

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.
