1. Cut the base blade of the cutting insert before entering, and cut the base part with a sharp knife to make an oblique mouth. The incision should be smooth so as to absorb moisture and nutrients. Change the water once every 3 days - 4 days. Do not move or change the direction within 10 days. About 15 days, you can grow silvery white fibrous roots.
2. It is not appropriate to change the water after rooting. Water evaporation can only be added in time after water evaporation is reduced. Often change the water easily cause leaf yellow branch wilt.
3. Apply a small amount of compound fertilizer in time after rooting, then the leaves are green and the branches are thick. If the fertilizer is not applied for a long time, the growth of the plant is thin and the leaf color tends to yellow. But fertilization should not be excessive, so as not to cause burning root or cause leggy. Apply fertilizer twice a month in spring and autumn. According to the information, in order to prevent leggy, Shuiyangguiguizhu should not apply chemical fertilizer. It is best to inject a few drops of brandy wine into the bottle every 3 weeks or so, and add a small amount of nutrient solution to keep the leaves green.
4. Do not place lucky bamboo on the side of the TV or in the places where air conditioners and electric fans often blow, so as not to dry the leaves and leaves.
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!
