大豆的产量取决于它的生育性状、体内营养状况、生理指标和经济性状的不同。近几年来,稀土微肥在大豆上的应用效果虽有些报道,但只是停留在产量水平上,对其内在效应和增产的理论依据尚无报道。自1988年以来,我们对稀土微肥在大豆上的使用进行了研究,并对其体内营养水平、生理指标、生物性状和产量性状进行了比较系统的测定,试图为稀土微肥的应用和推广提供理论根据。
Soybean production depends on its reproductive traits, in vivo nutritional status, physiological indicators and economic traits. In recent years, although the application effect of rare earth micronutrient fertilizer on soybean has some reports, it only stays on the output level, and the theoretical basis of its intrinsic effect and yield increase has not been reported yet. Since 1988, we have studied the use of rare earth micronutrient fertilizer in soybean and conducted a systematic measurement of its in vivo nutrition level, physiological index, biological traits and yield traits, and tried to apply and popularize the rare earth micronutrient fertilizer Provide theoretical basis.
