【摘要】 田间试验表明,叶面喷施硝基腐植酸、聚磷酸盐与微量元素配合物复合微肥,小麦每亩可增产40～50千克,小麦籽粒中蛋白质含量可增加10％,氨基酸总量增加14.3％,微量元素Zn、Fe等含量均显著增加。用示踪原子法进行不同配体环境下,有关元素在小麦植株体内的运转及在小麦籽粒内积累规律的研究,提出了中心体与配体在小麦籽粒内的积累,在一定条件下有协同作用的新观点。更多还原

【Abstract】 The field experiments show that the production of wheat increases by 40-50kg permu. In wheat seeds the quantity of protein increases by 10 percent, the total amount of amino acid increases by 14.3 percent, the amount of trace elements such as Zn ,Fe is obviously increased by spreading the complex fertilizer (NPTE) on wheat leaves. With different ligands, we used radioistopes to investigate the related elements transportation in the plant and accumulation in the seed. A new viewpoint is proposed that there is a coordination between the accumulation of the metal ions and the ligands in wheat seeds.更多还原
