摘  要：
【目的】研究不同追肥水平下北美海蓬子的生长和产量形成情况,为其引种栽培提供一定理论指导。【方法】以北美海蓬子为试验材料,调查不同尿素∶复合肥(1∶1)追施水平(0、75、150、225、300 kg/ha)下的生物性状表现并进行统计分析。【结果】追肥水平对北美海蓬子生育影响显著,在0~225 kg/ha两者呈正相关,追肥量为225 kg/ha时嫩茎产量高达30000 kg/ha、种子产量近3000 kg/ha,追肥量为300 kg/ha时产量开始下降。225 kg/ha是北美海蓬子生长和产量形成的适宜追肥量,在株高、茎粗、分枝数、生物量(尤其是地上部分)等多个生物性状上表现优越。研究获得株高、分枝数、节间长、茎粗与追肥量的相关性拟合曲线:y=30.069+1.845x-0.059x2、y=15.897+0.377x+0.019x2-0.001x3、y=1.997+0.073x-0.003x2、y=0.300+2.381×10-5x+0.001x2-4.667×10-5x3,各曲线均达到显著水平。【结论】北美海蓬子株高、分枝数、节间长、茎粗与追肥量的相关性拟合曲线均达到显著水平,尿素与复合肥(1∶1)225 kg/ha追肥量最有利于北美海蓬子生长和产量形成。

摘  要：
【Objective】Growth and yield formation of Salicornia bigelovii were studied by using different topdressing levels in order to provide theoretical references for introduction cultivation of Salicornia bigelovii. 【Method】The biological trait investigation and statistical analysis of Salicornia bigelovii were carried out by using different urea-compound fertilizer(1∶1) topdressing levels(0, 75, 150, 225, 300 kg/ha). 【Result】Topdressing levels of compound fertilizer had significant effects on growth and development of Salicornia bigelovii,and they showed a positive correlation within 0-225 kg/ha topdressing level. The peak yield of edible tender stems and seeds was about 30000 and 3000 kg/ha in the level of 225 kg/ha, respectively, while the effects of 300 kg/ha treatment began to decline. The topdressing level of 225 kg/ha was suitable for the growth and yield formation of Salicornia bigelovii,especially presented dominant in plant height,stem diameter,branch number and biomass(especially aboveground). The correlation fitting curves between plant height,branch number,inter-node length,stem diameter and topdressing level were obtained like as y=30.069+1.845x-0.059x2,y=15.897+0.377x+0.019x2-0.001x3,y=1.997+0.073x-0.003x2,y=0.300+2.381×10-5x+0.001x2-4.667×10-5x3,which reached the significant level. 【Conclusion】The correlation fitting curves between plant height,branch number,inter-node length,stem diameter and topdressing level reached significant level. The 225 kg/ha topdressing of urea-compound(1∶1) fertilizer was the best for growth and yield formation of Salicornia bigelovii.
