What are the remedial measures for missing seedlings and gaps in sesame rows?

(Agricultural Wealth Network) First, reseeding: when there is a serious shortage of seedlings and the sowing season has not yet passed, the land should be prepared or furrows opened in the same place for reseeding. Second, timely supplementary sowing: where missing seedlings and gaps in rows are very serious, seeds should be promptly pre-germinated and sown as a supplement; after the supplementary sowing emerges, field management of the seedlings should be strengthened, with timely thinning, final thinning and topdressing. Third, transplanting to fill gaps: where there are few missing seedlings and gaps in rows, when sesame has 4 to 5 pairs of true leaves, transplanting with soil can be combined with final thinning to fill the gaps. Fourth, borrowing space to keep seedlings: where there are only a few missing seedlings and gaps in rows, borrow space to keep seedlings. That is, during thinning and final thinning, keep paired seedlings near the places where seedlings are missing, which is equivalent to wide-row planting and can likewise give good results.
