摘要:
针对玉溪市江川县普通红皮洋葱生产上发生的发杈分球现象，以根际土壤及植株各部位器官为研究对象，采用对比法探讨了洋葱分球植株与正常株及其相应的根际土壤的相关营养元素含量状况。结果表明：洋葱发生发杈分球后，不但外部表现出发杈、分球等典型特征，而且内部相关营养元素也发生了明显的变化。洋葱分球株各部位的P元素的含量均明显高于正常株，而N、K元素的含量分球株均低于正常株，从而导致P/N、P/K值过高，N、P、K的比例不协调，同时Ca、Mg、Zn元素吸收量过高（主要富集于洋葱鳞茎和根中），而Mn元素含量太低也是导致洋葱分球发生的一个重要原因。
Abstract:
According to the ordinary red-skinned onions with bulb separation in Jiangchuan County in Yuxi，taking rhizosphere soil and all organs of the onion as research subject，bulb separation and normal onion and their nutrient elements of rhizosphere soil were discussed through antitheses.The results showed that the typical characteristics such as onion separation，bulb separation appeared from the exterior and the concerned nutrient elements obviously after onions bulb separation.The P in all parts of bulb separation onion was apparently higher than that of the normal plants，while N and K in the bulb separation onions were less than the normal plants，so that P/N，P/K were high too，the proportions of N，P，K were uncoordinated，the absorbed doses of Ca，Mg，Zn were too high (mainly concentrating in bulbs and roots)，while low Mn content was an important factor for bulb separation.
