摘    要:以北美海蓬子为材料,研究了不同施氮水平(0、150、225、300kg/hm2)与播种量(15、22.5、30、37.5kg/hm2)对北美海蓬子生长及籽粒产量的影响。结果表明:施氮水平与播种量对北美海蓬子生长特性及籽粒产量影响显著。适宜的施氮水平与播种量可促进北美海蓬子生长,提高籽粒产量。通过二次多项式回归分析得出籽粒理论最大产量时,施氮水平为327.6kg/hm2,播种量为31.6kg/hm2。

关 键 词:北美海蓬子  氮肥  播种量  籽粒产量

Abstract:A field experiment was carried out to study the effects of nitrogen levels(0、150、225、300 kg/hm2) and seeding rates(15、22.5、30、37.5 kg/hm2) on the growth and grain yield of Salicornia bigelovii Torr.The results showed that the effects were obvious.The suitable nitrogen level and seeding rate could promote the growth and increase the yield of Salicornia bigelovii Torr.The quadratic regression analysis results showed that when the nitrogen application rate was 327.6 kg/hm2 and the seeding rate was 31.6 kg/hm2,the theoretical maximum yield could be obtained.
Keywords:Salicornia bigelovii Torr  Nitrogen  Seeding rate  Grain yield
