Abstract: To explore the suitable sowing dates of winter rye (Secale cereale L.) in Horqin Sandy Land, the experiment was conducted using the variety ‘Bai BK-1’ as the experimental material. From August 10 to October 42 023, sowing was carried out every 7 days, with a total of 9 sowing dates, to investigate the effects of sowing dates on the green-up rate and production performance of winter rye. The results showed that with the delay of sowing dates, all indicators first increased and then decreased. When sown on September 14 and September 21, the green-up rate of winter rye reached 90%, with the highest green-up rate of 91.53% on September 14. The hay yield at maturity reached 20.00 t·hm-2 when sown on September 14 and September 21. The maximum values of hay yield (20.41 t·hm-2) and plant height (170.11 cm) both appeared under the sowing date of September 14. The crude protein content at each growth stage of winter rye showed the order: jointing stage > heading stage > maturity stage, with the corresponding maximum values at the three growth stages occurring under the sowing dates of September 7, September 14, and September 14, respectively. Under the sowing date of September 14, the contents of neutral detergent fiber and acid detergent fiber at the jointing, heading, and maturity stages were the lowest. Considering the forage yield and quality of winter rye comprehensively, the suitable sowing period in Horqin Sandy Land is from September 14 to September 21.

摘要: 为探究科尔沁沙地冬黑麦(Secale cereale L.)的适宜播期,以‘白BK-1’为试验材料,2023年8月10日至10月4日,每7天播种一次,共9个播期,探究播期对冬黑麦返青率和生产性能的影响。研究表明:随着播期的延后,各指标均呈先升高后降低的变化趋势。在9月14日及9月21日播种,冬黑麦返青率达到90%,在9月14日播种冬黑麦返青率最高达到91.53%;在9月14日及9月21日播种成熟期干草产量达到20.00 t·hm-2,干草产量和株高最大值均出现在9月14日播下,其值分别为20.41 t·hm-2和170.11 cm;冬黑麦各生育时期粗蛋白含量表现为拔节期>抽穗期>成熟期,3个生育时期相应的最大值分别出现在9月7日、9月14日和9月14日播期下;在9月14日播期下,冬黑麦拔节期、抽穗期和成熟期的中性洗涤纤维和酸性洗涤纤维含量最低。综合考虑冬黑麦的饲草产量和品质,科尔沁沙地在9月14日—9月21日播种较为适宜。
