Hastening Root-Formation in Rice Seedlings by Means of Supplying Straw-Ash to the Nursery Bed.

[摘要] It was observed by the authors that rice-straw-ash employed as top dressing on nursery beds promoted root-formation of rice seedlings after their transplantation, and moreover that the application done about 15 days before transplanting showed the most remarkable effect. Basing on the results of chemical analysis of seedlings concerned, it was assumed that supplying strawash at that time increased mostly sucrose content which is believed to be an important factor for hastening the root emergence of seedlings.
