A: Ring cutting, in general, every year in the middle and late June, after the ring cutting, smear the flower king 2, you can control the flower, disinfection, replace the traditional ring stripping and chemical hormone killing, completely eradicating the years. In addition to sprouting and thinning, the buds below 5 cm are wiped out, which is called germination; the new shoots that are over 5 cm thick are removed, which is called thinning. Twisting tips, for branches that are too strong, but not suitable for elimination, can be twisted to inhibit their growth. Topping the heart, removing the growth point of the shoots in the current year, called the topping, is suitable from June to July. Take the branch, take the branch is the hand to the Wang shoot from the base to the top of the sputum, hurt the xylem but not broken, have the effect of slowing growth, differentiation of flower buds and promoting short branches.

Roundness Measuring Instrument
A roundness meter is a measuring tool that uses the rotation axis method to measure the roundness error of a workpiece. The roundness tester is divided into two types: sensor rotary and workbench rotary. During measurement, the measured part is installed concentric with the precision shaft system, and the precision shaft is equipped with an inductive length sensor or workbench for precise circular motion. The roundness meter consists of an instrument's sensor, amplifier, filter, and output device. If the instrument is equipped with a computer, the computer is also included in this system.
A roundness meter is a precision instrument used to measure the out of roundness of a rotating surface (shaft, hole, or spherical surface) of a component. There are usually two types: small desktop, where the workpiece is mounted on a rotating workbench and the measuring head is mounted on a fixed column; Large floor mounted, with the workpiece installed on a fixed workbench and the measuring head installed on the rotating spindle. During measurement, the measuring head contacts the surface of the workpiece, and the rotating part of the instrument (workbench or spindle) rotates for one cycle. Due to the extremely high accuracy of the supporting bearings in the rotating part, the measuring head will generate a high-precision circular trajectory on the measured surface during rotation. The out of roundness of the measured surface causes the measuring head to shift and transform into an electrical (or pneumatic) signal. After amplification, it can be automatically recorded on a circular recording paper, and the out of roundness of each part can be directly read out for accuracy evaluation and process analysis. Widely used in precision bearings, machine tools, and instrument manufacturing industries.
The roundness meter adopts a radius measurement method and operates in a rotating manner. The rotation axis system of the roundness meter adopts a high-precision air floating spindle as the measurement reference; The electrical part of the roundness tester is composed of advanced computers, precision circular grating sensors, and precision inductance displacement sensors. The circular grating sensors and precision inductance displacement sensors measure angle and radial displacement, ensuring the accuracy of measuring the angular displacement and radial value of the workpiece; The roundness meter measurement software adopts a roundness measurement software based on the Chinese version of WinXP operating system platform, completing data collection, processing, and measurement data management.
