生长锥是常用测定径向生长的工具之一。可惜,还缺少一种在野外精确量测用生长锥所钻木条的简便仪器。为此,我们设计出一种生长测微器。仪器本身结构简单(见图)。主要部件是钳工用测微器MK-75的部件—计量器1。1 Growing cones are one of the tools commonly used to measure radial growth. Unfortunately, there is a lack of a simple instrument for accurately measuring the wood in a field by using a growth cone. To this end, we have devised a micrometer. The device itself is simple (see photo). The main part is the part of the fitter MK-75 - Meter 1.1
