Where is the weakness of ginger seedlings?

April 29, 2021

Recently, when the reporter went to Lincang Township in Anqiu, he encountered a farmer in the field who frowned. It turned out that his family's shed ginger was more than half an hour earlier than the open-air ginger, and the base fertilizer was not used. However, the ginger did not grow long after the emergence of the ginger. The ginger seedlings were weak, and the leaves began to yellow from the lower part. The growth was not as good as before. Open air ginger.
The reporter pulled two plants from the ginger field and removed the ginger roots and found something that was black near the ginger root. When we look closely, the pig manure and bean cake in the base fertilizer are originally used, and the roots near the ground have turned brown and rot. Obviously, the ginger root is burned, and the absorption of water and fertilizers is hindered. It is not surprising that the ginger seedlings are weak. The ginger farmer said annoyed that in order to catch up early before planting, he hastily used basic fertilizer, no pluralities, and concentrated in the ginger ditch. The ginger roots touched these fertilizers when he was under the roots and gave roots to “burn”. More seriously, he discovered that Jiang Miao was not growing well. He mistakenly thought it was caused by lack of water and lack of fertilizer. He also applied a lot of fertilizer and aggravated his illness.
The reporter suggested that water should be poured first and water stress should be used to relieve the damage. And then with water flushing or irrigation with yeast, lactic acid bacteria, actinomycetes and other microbial components of the "rooting power" 800 times, to improve the root environment and promote rooting. At the same time, it is recommended that the leaves be sprayed with organic starfish fertilizer to make up for the lack of nutrient and poor growth of stems and leaves due to root injury.

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.
