研究了夏播芝麻对氮、磷、钾等９种营养元素的吸收规律及其与干物质积累的关系。结果表明，夏播芝麻在不同生育阶段各器官的营养元素含量与分配状况不同。在全生育期内营养器官中的各元素含量前期高后期低，生殖器官中的元素含量则一直增加。磷、钙、锌和铜在花期～封顶期吸收积累量最多，与芝麻干物质积累基本同步；而氮、钾、镁、锰和铁的吸收超前于干物质积累，在苗期～花期阶段积累达到高峰）。施肥影响各营养元素在体内的含量、积累与转移。
The effects of nitrogen, phosphorus and potassium on the absorption of nine nutrient elements and their relationship with dry matter accumulation were studied. The results showed that the content and distribution of nutrient elements in different organs of summer sowing sesame were different. During the whole growth period, the content of each element in vegetative organs is low in the early period and the content of elements in the reproductive organs increases. Phosphorus, calcium, zinc and copper had the most absorption and accumulation in the senescence-topping period, and were basically synchronized with the dry matter accumulation of sesame. The absorption of nitrogen, potassium, magnesium, manganese and iron was ahead of the accumulation of dry matter, and accumulated in the stage of seedling to flowering Peaked). Fertilization affects the nutrient content in the body, accumulation and transfer.
