摘要
为了解决重庆市苦荞品种产量低、籽粒小、退化严重等问题,于2021—2022年连续两年对9个苦荞品种进行物候期、农艺性状和产量的对比试验。结果表明:K1206两年平均生育期为72 d,为晚熟品种;在两年试验中产量分别为1834.20、2125.65 kg/hm^(2),分别较对照品种九江苦荞增产16.45%、23.13%,平均产量居参试品种第一位;抗倒性较好,两年倒伏率分别为10%、5%,适应性较强。因此,K1206可在重庆市进行大面积推广种植。
In order to solve the problems of low yield,small grain size,and severe degradation of Fagopyrum tataricum varieties in Chongqing City,a comparative experiment was conducted on phenological period,agronomic traits,and yield of 9 Fagopyrum tataricum varieties from 2021 to 2022.The results showed that the average growth period of K1206 in two years was 72 days,making it a late maturing variety.In the two years experiment,the yield was 1834.20 kg/hm^(2) and 2125.65 kg/hm^(2),respectively,increased by 16.45%and 23.13%compared with the control variety Jiujiang Kuqiao;the average yield ranked first among the tested varieties.K1206 had good lodging resistance,with a lodging rate of 10%and 5%in 2021,2022,indicating strong adaptability.Therefore,K1206 can be widely promoted and planted in Chongqing City.
