2018-2021年河北省苹果苗机械化嫁接质量与成活质量数据

资源包括两个苹果嫁接基地中嫁接苗的嫁接作业质量和嫁接作业后成活的质量指标，包括数据采集时间和地点以及每株果树苗的砧木直径、穗木直径，其中样本均为适于当地自然条件，且作为矮化砧大面积推广的八棱海棠和GM256。各直径值指标中嫁接作业质量主要指接穗长度、蘸蜡深度、缠膜高度，成活质量指标以嫁接苗成活后上芽的长度数据，未成活的苗包括成活后在数据采集时死亡的，上芽长度均记为零。

This dataset includes quality metrics for grafting operations and post-grafting survival of grafted apple seedlings from two apple grafting bases. Collected data encompass the time and location of data acquisition, along with the rootstock diameter and scion diameter of each apple sapling. The test samples are exclusively Malus robusta (Eight-Ribbed Chinese Crabapple) and GM256, which are adapted to local natural conditions and widely promoted as large-scale dwarfing rootstocks. Among all measured indicators, the grafting operation quality mainly refers to scion length, wax dipping depth and film wrapping height. The survival quality metrics are represented by the length of the upper bud of grafted seedlings post-survival; for non-surviving seedlings, including those that initially survived but died by the time of data collection, the upper bud length is recorded as zero.
