摘要: 在轻盐碱地大田条件下,研究了从美国引进紫花苜蓿品种WL323和ARRIBA在不同播量条件下生育情况和产量表现。结果表明:不同播种量对两个紫花苜蓿品种的植株发育影响显著;随公顷播种量的增加,两品种均在播种量30.0 kg/km2时第一茬干草产量达到最高值,但播量进一步增加导致产量显著下降,ARRIBA减产幅度高于WL323。回归分析表明:在盐碱地种植条件下,WL323和ARRIBA获得理论最高产量的播种量分别为28.9 kg/hm2和29.4 kg/hm2。

Abstract: In light salina,plant growth and yields of alfalfa WL323 and ARRIBA introduced from the USA were respectivelyinvestigated.The result showed that different quantities of seeds sewed affected the growth of two cultivars significantly;With quantities of seeds sewed increased,yields of both cultivars reached the top when 30.0 kg/ka seeds weresewed.However,over 30.0 kg/ka seeds sewed resulted in less yield decrease of WL323 than that of ARRIBA.Regressiveanalysis showed that in light salina,quantities of seeds sewed ofWL323 and ARRIBA to get top theoretical yields were respectively 28.9 kg/ha and 29.4 kg/ha.
