Is this poem the work of Su Zhe? And what is the meaning of "spring tantalum" in the poem?

It's not Su Zhe's work, but Huang Tingjian's.

The original text is as follows

Stay in Tankou for three days (works by Huang Tingjian)

It's stormy in the lonely city for three days, and people in small cities only eat vegetables.

Shui Yuan Mountain is full of jade, and I am idle and bitter for a spring.

Weng came to the side room to close the net. I don't fish in deep water.

Between pitching and pitching, there are traces of the past, and the twilight window belongs to reading.

Tantalum: Egret, with its pecking posture like a farmer's hoe, hence its name.

It is the author's ambition: indifferent to fame and fortune, willing to be poor.
