随着作物产量的提高,氮磷肥的大量施用,作物必需的微量元素锌长期得不到补充,土壤中的养分失去平衡,影响作物生育、产量和品质。1983～1984年我们利用同位素技术配合省科委组织的攻关协作方案进行了盆栽试验。研究锌在高粱和玉米体内的吸收、运转及其在各部位的分配,作物对锌肥的利用,以及N、P元素对Zn吸收的影响和相互关系,为合 With the increase of crop yield, the large amount of application of N and P fertilizers has not been supplemented for a long time. The nutrients in the soil are out of balance and affect crop growth, yield and quality. From 1983 to 1984, we used isotope techniques to cooperate with the scientific and technological cooperation programs organized by the Provincial Science and Technology Commission to conduct pot experiments. To study the absorption and transport of zinc in sorghum and maize and their distribution in different parts of the soil, the utilization of zinc in crops and the effects of N and P on Zn uptake,
