Two field experiments were conducted to evaluate six Salicornia species (Salicornia bigelovii Torr., S. europaea L., S. persica Gorgan ecotype, S. persica Urmia ecotype, S. sinus persica Bushehr ecotype, and S. persica Central Plateau ecotype) at different planting dates and densities under irrigation with Persian Gulf water. Evaluated planting dates were 14 November and 18 December 2016 and 16 January, 8 February, 8 March, and 28 March 2017. Examined planting densities included 13, 20, and 40 plant m. Only S. bigelovii and S. europaea produced measurable yield in all planting dates. The highest dry weight (651.1 gm) was obtained in S. sinus persica (Bu) planted on 8 February. Dry weight of S. bigelovii, S. europaea, S. sinus persica Bushehr, S. persica Central Plateau, S. persica Gorgan, and S. persica Urmia planted on 8 March were 174.2, 220.7, 542.5, 240.9, 158.0, and 147.5 g m, respectively. The ash contents of S. bigelovii, S. europaea, S. sinus persica Bushehr, S. persica Central Plateau, S. persica Gorgan, and S. persica Urmia were 46.3%, 45.0%, 49.6%, 49.6%, 50.0%, and 53.1%, respectively. Sodium and chloride contents of different Salicornia species varied from 13-15% and 16-17%, respectively. The oilseed content of S. bigelovii and S. sinus persica Bushehr was about 24.0% for both species. The highest and lowest dry weight, from the second experiment, were for S. sinus persica Bushehr and S. persica Central Plateau, respectively, in all planting density. The highest dry weight equal to 1336.2 gm was obtained for S. sinus persica Bushehr in 40 plant m density. Under such conditions, forage production potential of Salicornia is more achievable rather than seed production. Nevertheless, high ash content is a serious constraint to direct consumption by livestock; therefore, determining the nutritional value of Salicornia fodder requires further evaluations.
在波斯湾灌溉条件下，对 6 种盐角草（盐角草、欧洲盐角草、戈根生态型波斯盐角草、乌尔米亚生态型波斯盐角草、布什尔生态型波斯盐角草和中央高原生态型波斯盐角草）在不同种植日期和密度下进行了两次田间试验。评估的种植日期为 2016 年 11 月 14 日、12 月 18 日和 2017 年 1 月 16 日、2 月 8 日、3 月 8 日和 3 月 28 日。检查的种植密度包括 13、20 和 40 株/米。只有盐角草和欧洲盐角草在所有种植日期都能产生可测量的产量。在 2 月 8 日种植的布什尔盐角草（Bu）中获得了最高的干重（651.1 克）。在 3 月 8 日种植的盐角草、欧洲盐角草、布什尔盐角草、中央高原盐角草、戈根盐角草和乌尔米亚盐角草的干重分别为 174.2、220.7、542.5、240.9、158.0 和 147.5 克/米。盐角草、欧洲盐角草、布什尔盐角草、中央高原盐角草、戈根盐角草和乌尔米亚盐角草的灰分含量分别为 46.3%、45.0%、49.6%、49.6%、50.0%和 53.1%。不同盐角草种的钠和氯含量分别为 13-15%和 16-17%。盐角草和布什尔盐角草的油籽含量约为 24.0%。在所有种植密度下，第二次试验中干重最高和最低的分别是布什尔盐角草和中央高原盐角草。在 40 株/米的密度下，布什尔盐角草的干重达到了 1336.2 克。在这种条件下，盐角草的饲料生产潜力比种子生产潜力更容易实现。然而，高灰分含量是直接被牲畜食用的严重限制因素；因此，需要进一步评估盐角草饲料的营养价值。
