以5个不同生态类型的大豆品种为试验材料,分别施用3个不同水平的氮肥,研究种肥对5个不同基因型大豆品种产量及品质的影响。研究表明,在草甸黑钙土上施用氮肥,对大豆的产量和品质均有显著影响,且对不同品种的影响各不相同。就产量而言,增施氮肥提高了晚熟品种黑农37和早熟品种东农44的产量,降低了中熟品种东农48和东农53的产量;就品质而言,增施氮肥提高了绥农14籽粒中蛋白质含量,降低了其余4个品种籽粒中蛋白质含量,提高了黑农37籽粒中油分含量,降低了绥农14和东农48籽粒中油分含量。
Five different ecological soybean varieties were used as experimental materials, and three different levels of nitrogen fertilizer were applied to study the effects of different kinds of fertilizers on the yield and quality of five different soybean genotypes. Studies have shown that the application of nitrogen fertilizer on the meadow chernozem has a significant impact on the yield and quality of soybean, and the impact on different varieties vary. In terms of yield, the application of nitrogen fertilizer increased the yield of late maturing cultivar Heinong 37 and the early maturing cultivar Dongnong 44, and reduced the yield of middle maturing cultivar Dongnong 48 and Dongnong 53; in terms of quality, the application of nitrogen fertilizer increased Sui The content of protein in Zhongnong14 decreased the protein content in the remaining four varieties, increased the oil content in Xingnong 37, and decreased the oil content in Suinong14 and Dongnong48.
