Why does Basswood planting fungus require yellow leaves to cut trees?
Basswood cultivates black fungus, and the nutrients and water needed for growth and development come from ear wood. Therefore, timely cutting of trees is very important to improve the quality of ear wood. my country has a vast territory, diverse climates, complex vegetation, and a wide variety of trees, and the time for cutting trees cannot be unified. Generally speaking, when the leaves of the ear tree turn yellow until the ear tree is about to sprout, it is the right time to cut the tree. Ear farmers call it "yellow leaf cut tree". During this period, the trunk stores the most abundant nutrients, the leaves do not flow fast, and the bark and xylem are tightly combined, and they are not easy to fall off when moved. In addition, if the method of cutting trees is proper, "yellow leaves cutting trees" will also help the remaining tree stumps (such as oaks) to sprout and regenerate and maintain ecological balance. The cultivation of basswood of shiitake mushrooms and white fungus also requires "yellow leaves to cut trees."

Industrial Laser Distance Sensor
Industrial Laser Distance Sensor, we also call it secondary development laser distance module, which support TTL level and CMOS. The laser range sensor can be widely used in professional surveying, mapping, construction, robots, hunting arrows, industrial monitoring and automated measurement applications in electricity, transportation, etc. Our laser distance module supports data communication with RS232, USB with a simple adapter. The results of laser distance sensor can be evaluated with Arduino. We are always looking ahead, hoping we can make every measurement simple in life!
