Abstract

Abstract:

This study was conducted with Yongyou 1540 and Huazheyou 261 as experimental materials to explore the effects of seedling cultivation using rock wool and a specialized substrate for rice seedling-raising on seedling growth, physiological characteristics, and rice yield under different moisture conditions. The results showed that in terms of emergence rate, the specialized substrate for rice seedling-raising performed better than rock wool seedling-raising. However, under conditions of high temperature and water stress, seedlings raised with rock wool exhibited advantages over those raised with the specialized substrate in terms of plant height and dry matter accumulation. Moreover, rock wool seedling-raising also increased the soluble sugar content and elevated the carbon-to-nitrogen ratio in the seedlings. Additionally, compared to the specialized substrate for rice seedling-raising, rock wool had better water retention properties, which effectively enhanced the drought resistance of rice seedlings. In terms of yield, rock wool seedling-raising also demonstrated certain advantages, showing an 8.2% increase compared to seedling-raising with the specialized substrate.

Key words: rice, rock wool, substrate, drought stress, seedling raising, physiological characteristics, grain yield

摘要：

以甬优1540和华浙优261为试验材料，研究不同水分条件下岩棉和水稻专用基质育秧对秧苗生长状况、生理特性及水稻产量的影响。结果显示，在成苗率方面，水稻专用基质育秧表现优于岩棉育秧。然而，在高温环境以及水分胁迫条件下，岩棉所育秧苗在株高和干物质积累方面较专用基质所育秧苗有优势。不仅如此，岩棉育秧还能使秧苗体内可溶性糖含量增加，碳氮比升高。此外，相较于水稻育秧专用基质，岩棉具备更优良的保水性能，这一特性有助于有效增强水稻秧苗的抗旱能力。在产量方面，岩棉育秧也表现出一定的优势，较专用基质育秧增产8.2%。
