冬剪实习是农职中林果专业的一个重点和难点。说它是重点,是因为冬剪技术是林果专业学生必备的基本技能之一,说它是难点,是因为由于缺乏量化标准,对冬剪实习的效果和学生们的技术水平很难做出客观评价。我在多年的教学实践中逐步总结出一套量化考核指标,让每个学生独立修剪一棵树,然后根据量化指标对其作业进行评分。这套指标实施后,效果不错。下面以苹果树修剪为例将几项量化指标简述如下。第一项指标:品种识别由于果树各品种有着不同的生物学特性,所以对应的修剪手法也迥然不同。故修剪前必须首先区分出果树的品种。如美夏、红玉等品种成枝力强,对修剪反应敏感,应以疏为主,少短截,减少枝量,以 Winter shear internship is a key and difficult task in the forest professional. It is important because winter shears are one of the basic skills essential for undergraduates and say it is difficult because of the lack of quantitative standards that make it difficult to do winter internship and student skills Out of objective evaluation. I gradually summed up in a number of years of teaching practice quantitative assessment indicators, so that each student pruning a tree independently, and then according to the quantitative indicators of their homework score. After the implementation of this set of indicators, the effect is good. The following example of apple tree pruning will be several quantitative indicators as outlined below. The first index: Variety identification Because of the variety of fruit trees have different biological characteristics, so the corresponding pruning tactics are also very different. Therefore, before pruning must first distinguish between varieties of fruit trees. Such as the United States summer, ruby ​​and other varieties of branches strong, sensitive to pruning reactions should be sparse-based, less short cut, reduce the amount of branches to
