氮肥施用量对不同大豆品种产量及品质的影响

Yield and quality effects of different soybean varieties by using nitrogen fertilizer

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 types of soybean varieties for the test material, respectively, applying three different levels of nitrogen fertilizer to study five different kinds of fertilizer on soybean yield and qualily of genotypes study. Studies have shown that, in the meadow chernozem on the application of nitrogen fertilizer on soybean yield and quality were significantly affected, and had different impacts of different varieties. The production, the increased use of nitrogenous fertilizers increased Heinong 37 late-maturing varieties and Dongnong 44 early-maturing varieties of agricultural production and lower mid-maturing varieties of Dongnong 48 and Dongnong 53; in the respect of the quality, the increased use of nitrogenous fertilizers increased Suinong 14 Grain protein content to reduce the remaining four varieties of grain protein content, increased seed Petroleum Heinong 37 oil content, reducing Suinong 14 and Dongnong 48 oil content.
