步骤
-
把洋葱芽种到优质的盆栽土里，深度2.5厘米。 为每棵洋葱芽单独挖一个洞，栽进去之后埋好土，只让绿色的部分露出土面。两棵洋葱芽之间的距离至少得有7.5厘米，或者使用单独的盆栽栽种，以免它们争夺空间。 [3] X 研究来源 考虑在土壤上覆盖一层薄薄的护根物，以促进生长。
-
每天检查植物周围有没有杂草，一旦看到，立即拔掉。 在洋葱生长的过程中，它们周围会长出杂草，这是不可避免的。戴上园艺手套，确保野草被连根拔起，以免它们卷土重来。
-
每周用杀菌喷雾剂喷洒两次。 这种喷雾剂可以防止有害真菌伤害植物，确保植物能够保持健康。每株植物上喷几下应该就够了。 [9] X 研究来源
- 如果你不喜欢使用人工化合物，可以选择氧化剂或紫铜喷剂。 [10] X 研究来源
