摘要：

为筛选适配江西省机械化生产的高产再生稻品种，于2024年在江西省红壤及种质资源研究所余江基地开展田间试验，系统评估13个水稻品种的生育特性、产量潜力、再生能力及耐机械碾压性。 结果显示，参试品种头季全生育期134~139 d，再生季69~80 d，两季生育总天数206~215 d；头季稻单产362.8~574.9 kg/667 m2，再生季单产222.9~450.3 kg/667 m2，两季总产621.3~974.9 kg/667 m2；再生力系数0.54~1.09，耐碾压性1.3%~40.6%。综合评价表明，玮两优8612兼具高产量（两季总产974.9 kg/667 m2）、强再生能力及优异耐碾压性，适宜作再生稻进行大面积机械化生产。航两优1378、旱两优8208和旱优3015再生能力和耐碾压能力较强但产量相对低，甬优4949、宸两优菲占和玮两优7713产量较高但耐碾压能力较弱，作再生稻时应加强配套栽培技术研究。

Abstract:

To identify high-yielding ratoon rice varieties suitable for mechanized production in Jiangxi Province, a field trial was conducted in 2024 at the Yujiang Experimental Base of the Jiangxi Institute of Red Soil and Germplasm Resources. The growth period, yield potential, regeneration power, and mechanical rolling resistance of 13 rice varieties were systematically evaluated. The results indicated that: (1) the total growth period of the main crop ranged from 134 to 139 days, with the ratoon crop lasting 69 to 80 days, resulting in a combined growing period of 206 to 215 days; (2) the main crop yields were 362.8-574.9 kg/667 m2, ratoon crop yields were 222.9-450.3 kg/667 m2, and total two-season yields 621.3-974.9 kg/667 m2; (3) the regeneration force coefficient ranged from 0.54 to 1.09, and the mechanical rolling resistance ranged from 1.3% to 40.6%. A comprehensive evaluation revealed that Weiliangyou 8612 exhibited high total yield, strong regeneration power, and good performance in mechanical rolling resistance, making it well-suited for widespread mechanized ratoon rice cultivation. Hangliangyou 1378, Hanliangyou 8208, and Hanyou 3015 demonstrated strong regeneration power and good performance in mechanical rolling resistance but relatively lower yields, whereas Yongyou 4949, Chenliangyou Feizhan, and Weiliangyou 7713 achieved higher yields but weaker mechanical rolling resistance, so the cultivation technology of these varieties in ratoon rice production should be strengthened.

Key words: ratoon rice, variety evaluation, mechanized production, yield, regeneration power, mechanical rolling resistance
