耐盐植物番杏在泉州湾的栽培试验

Studies on cultivation trial of salt-tolerant New Zealand spinach in Quanzhou Bay

摘要: 研究了盐度对番杏种子萌发的影响,结果表明:番杏种子在盐度为0和5g/L时具有最高的发芽率和萌发指数,在盐度10g/L时发芽率只有9.0%,在盐度15g/L时基本不萌发。番杏在泉州湾的适生性研究结果表明,在海边未受海水淹没的盐碱地栽培番杏100%存活,生长状况良好,可完成整个生活史过程,相对生长率达到1965.28%;经常受到海水周期性淹没的地带不适宜种植番杏。

Abstract: In this paper, effects of salinity on seed germination of New Zealand spinach were studied. The results showed that there were highest germination rate and germination index at 0 g/L and 5 g/L salinity while was only 9.0% of germination rate at 10 g/L salinity and basically lack of germination rate at 15 g/L salinity. The study on adaptability of New Zealand spinach in Quanzhou Bay showed that it showed 100% survival rate at saline-alkali soil where did not flooded by seawater, healthy growth condition, could complete whole life cycle and its relatively growth rate was 1965.28%; while it could not adapt to the areas where frequently flooded by seawater.
