摘要
以齐黄34为试材,研究不同种植密度条件下有机无机肥配施对夏大豆氮肥利用效率的影响。结果表明,有机肥无机肥和15万株/hm^(2)配合种植可以显著提高大豆叶片、茎秆、籽粒等含氮量及氮素积累量,改善大豆后期籽粒中氮的分配量,提高植株氮肥利用率。
With qihuang 34 as the test material,the effects of organic and inorganic fertilizer combined application on nitrogen use efficiency of summer soybean under different planting densities were studied.The results showed that the combination of organic fertilizer and inorganic fertilizer and 150,000 plants/hm^(2) planted together could significantly increase the nitrogen content and nitrogen accumulation in leaves,stalks and grains of soybean,improved the nitrogen distribution in grain at the later stage of soybean,and improved the plant nitrogen use efficiency.
