It’s quite a complex question since it requires the basic understanding of what deconstruction is. And to make it very easy for the readers, the guy who pioneered this approach (Jacques Derrida) said that we cannot define the deconstruction in any way. Because the definition itself contradicts the very nature of this...whatever it is. So I personally have a very vague idea of how you can apply deconstruction to the poem analysis.
However, I’ve found the paper exactly on your topic, check it out here. But I’m sure there is no one precise way to look at that.
