Li Shuyi became a flower, but it was often full of trees and half trees. Blossoming, nutrient consumption, serious fruit drop. There are generally three peaks in the plum drop: the first fall, since the flowering is completed, the reason for the fall is mainly due to incomplete flower development, loss of fertility or unfertilized. The second drop occurred about 29 days after flowering. When the fruit resembled the size of the bean, the young fruit and the fruit stem turned yellow until the nucleus began to harden. This is mainly due to poor pollination and fertilization. Such as lack of pollination trees, lack of pollinators, low flowering, pollen tubes can not normally extend. The third fruit drop, also known as "June fruit drop," began about three weeks after the second fruit drop, with less fruit drop. The main reason for fruit drop is lack of nutrition. The development of embryos stops halfway, resulting in decline and eventually causing fruit drop.
JRT usb interface distance sensor board adds a USB port to a Laser Distance Sensor, inexpensive laser distance measurement sensors, allowing customers directly using GBeacon-2.3-Fx.exe software to control the rangefinder sensor. Usb laser distance sensors are the the most popular model devices, it works by measuring the phase of an visible-red laser beam that reflects on the target. Usually, customers would like to choose CH341SER.EXE version to test.
