资源简介：
在山东省蓬莱、淄博、威海地区采集31个苹果园的土壤，分0-20cm和20-40cm两层进行取样，每个苹果园采用“X”型5点取样法进行土壤样品采集，取混合样，共62个样品，测定硝态氮、铵态氮、速效钾、速效磷含量
Soil samples were collected from 31 apple orchards located in Penglai, Zibo, and Weihai of Shandong Province. For each apple orchard, composite soil samples were collected via the five-point sampling method in an 'X' pattern, with two soil layers (0–20 cm and 20–40 cm depth) sampled, yielding a total of 62 soil samples. The contents of nitrate nitrogen, ammonium nitrogen, available potassium, and available phosphorus were subsequently determined for all samples.
