资源简介：
于2019年4月-6月在河北省农林科学院农业资源环境研究所网室内进行培养试验，2个菜豆品种、4个氮水平、2个磷水平，共采集植株（地上部+地下部）样品192个，根瘤样品96个，冲掉泥土吸净水分称鲜重、杀青烘干数据。
A pot cultivation experiment was conducted in the screen house of the Institute of Agricultural Resources and Environment, Hebei Academy of Agricultural and Forestry Sciences from April to June 2019. Two common bean cultivars, four nitrogen levels and two phosphorus levels were arranged in the experiment. A total of 192 plant samples (aboveground + underground parts) and 96 nodule samples were collected. For each sample, adhering soil was rinsed off, surface moisture was blotted dry, fresh weight was measured, followed by heat fixation (kill-green treatment) and oven-drying for subsequent data acquisition.
