【摘要】 以临黑2号、临黑3号为试验材料,研究在大田生态模式下,花荚期叶面喷施不同浓度硒肥对夏播黑大豆产量构成因子和品质影响。结果表明:两个黑大豆品种叶面喷施不同浓度的绿维康有机富硒肥产量均有增加,但各处理间差异不显著;产量构成因子各处理间差异不显著,籽粒硒含量比对照显著增加。临黑2号在硒肥喷施浓度为0.1%时,产量最高,籽粒蛋白质含量和蛋脂总含量最高,籽粒硒含量随硒肥浓度增加而增加;临黑3号在硒肥喷施浓度为0.2%时,产量最高,籽粒蛋白质含量和蛋脂总含量最高,硒肥喷施浓度为0.3%时,籽粒硒含量达到最大。更多还原

【Abstract】 The summer-seeding black soybean Linhei 2 and Linhei 3 were used as experiment material.the yield components and quality of black soybeans was effected at different concentrations selenium fertilizer spraying on black soybeans leaf surface in flower pod in the field ecological mode. The results showed that the yield of the two black soybean varieties increased by spraying on different concentrations Luweikang organic selenium-enriched fertilizers, but the efforts were not significant between treatments.The yield component factors were not significantly different between treatments, and the grain selenium content was higher than the control significant. Linhei 2 had the highest yield when the selenium fertilizer on 0.1% concentration was sprayed, and the total content of protein and fat were highest. The grain selenium content increased with the increase in selenium fertilizer concentration. Linhei 3 had the highest yield at 0.2% concentration, the total content of protein and fat were highest. The grain selenium content was the maximum at 0.3% concentration.更多还原
