为了明确冀8158在滨海盐碱棉区种植时的产量表现和耐盐性情况,2015~2016年在唐海、芦台、汉沽、丰南、宁河进行了2 a多点产量试验。结果显示,其不同试点和年度间的产量及产量构成性状差异均较小,平均单铃重7.4 g、单株铃数19.2个、衣分40.9%、吐絮集中度71.7%,平均子棉产量(4 562.7 kg/hm~2)和皮棉产量(1 868.0 kg/hm~2)均较对照品种冀丰1271增产10%以上;同期,在唐海进行了耐盐性鉴定试验,结果显示,其发芽期耐盐,苗期和全生育期均强耐盐。冀8158在滨海盐碱棉区表现丰产、稳产、大铃、结铃性强、吐絮集中、耐盐,适宜在该区轻简化管理,进行大面积推广。
In order to clarify the yield performance and salt tolerance of Hebei 8158 planted in coastal saline-alkali cotton area, a multi-point yield test of 2 years was carried out in Tanghai, Lutheran, Hangu, Fengnan and Ninghe from 2015 to 2016. The results showed that there was little difference in the yield and yield components between different experimental plots and annual yield. The average single boll weight 7.4 g, number of bolls per plant 19.2, clothing percentage 40.9%, litter concentration 71.7% 4 562.7 kg / hm ~ 2) and lint yield (1 868.0 kg / hm ~ 2) increased more than 10% compared with that of Jifeng 1271. In the same period, salt tolerance identification test was conducted in Tanghai Sea. The results showed that germination Salt-tolerant, seedling and full growth period are strong salt. Ji 8158 in the coastal saline-cotton area showed high yield, stable yield, large bell, boll and strong, bolting concentration, salt, light in the area to simplify management, for large-scale promotion.
