木豆引种筛选试验

Screening test for introduction of Cajanus cajan

为筛选适宜贵州省草地生态畜牧发展需求的豆科牧草品种,采用随机区组法对参试26份木豆(Cajanus cajan)材料进行比较试验。结果表明,(1)参试材料均能正常开花结实,完成整个生育周期,其生育期为168~226 d,成熟期株高为124~286 cm;(2)鲜草产量较高,在65.41~67.18 t/hm^(2)之间的材料分别是201510、201505、201502、201508、201516;(3)种子产量较高,在3252.45~4221.58 kg/hm^(2)之间的材料分别是201516、引进料黄色、201511、201507、201517等5份材料;(4)通过引种筛选试验分别提出了5个适宜牧草和种子生产利用的品种,为生产上不同用途的推广利用提供了优良品种。

To screen legume forage varieties that were suitable for the development of grassland ecological animal husbandry in Guizhou Province,twenty-six tested materials of Cajanus cajan were compared by the random block method.The results showed as follows:(1)All tested materials could normally blossom and pod bearing and complete the whole growth cycle.The growth period was 168~226 days,and the plant height at maturity was 124~286 cm.(2)The highest yield of fresh grass was 201510,201505,201502,201508 and 201516 in 65.41~67.18 t/hm^(2).(3)The highest seed yield of 3252.45~4221.58 kg/hm^(2)was 201516,yellow Cajanus cajan,201511,201507 and 201517.(4)Five varieties suitable for forage and seed production utilization were proposed respectively through the screening test for introduction,providing excellent varieties for promotion and utilization of different uses in production.
