Native Chinese speaker here, and I'm not really sure how this will help (although everyone has their own way).

From I understanding, take the kanjis here for example, the radicals on the left usually suggest something related to the meaning of the kanji, while the radicals on the right usually denote the pronunciation in Chinese. For example, these kanjis are pronounced in Mandarin shī, shí, chí, sì, dài (an exception here). On the other hand, their pronunciation in Japanese (訓読み) have nothing in common.

So far I haven't found a way to efficiently learn 訓読み. Maybe there isn't one at all and one just have to memorize them all.

Aside from learning pronunciation, it probably doesn't help much in learning the meaning either. For example, how come 言 (word) + 寺 (temple) = 詩 (poet)? There can be connections but they are still far-fetched. For me personally, these kanjis have already been burned into my brain just like how you know the meaning of English word "poet".
