| 摘 要： | 采用0.01;、0.02;、0.03;、0.04;和0.05;浓度的稀土,在苜蓿的返青、分枝、现蕾、盛花期进行了叶面喷施,观察对苜蓿种子产量及构成因素的影响.结果表明,在苜蓿种子生产中,科学使用稀土能够有效提高种子产量.试验中以叶面喷施0.03;浓度的稀土处理效果最佳,其分枝数、结荚花序数、荚果数、种子粒数分别比对照增加了43.81;、23.0;、18.62;和30.5;,种子产量增加17.75;,生产中有推广应用价值.

| Abstract: | Lanthanon solution of 0.01%,0.02%,0.03%,0.04%,0.05% concentration was applied to alfalfa through spraying on leaf surfaces in the period of turning green,offshoot,budding and prosperous florescence to analyze the seed yield and components of yield of alfalfa.The results show that Lanthanon affects the seed yield and components of yield markedly through correct spraying.The solution of 0.03% had a significant improving effect on seed yield,which made the seed yield increase by 17.75%,fertile shoots increase by 43.81%,the number of racement increase by 23.0%,the number of pod increase by 18.62%,the seed grains increase by 30.5%.Lanthanon is worth popularizing in seed production of alfalfa. |
