氮和钾都是疽物生长所必需的基本营养元素,在植物的生命过程中起着极其重要的作用。虽然这两种元素在植物体内的存在形态及生理功能迥然不同,但它们在植物的营养生理上却有着密切联系和相互影响。本文根据一些试验的植株分析结果就不同施氮水平下,春小麦氮、钾营养间的关系作一初步探讨,为河西灌区土壤条件下春小麦的合理施肥提供依据。
Both nitrogen and potassium are essential nutrients for the growth of anthrax and play an extremely important role in the life of plants. Although these two kinds of elements are very different in their existing forms and physiological functions in plants, they have a close relationship and mutual influence in the vegetative physiology of plants. Based on the results of plant tests in some experiments, the relationship between nitrogen and potassium nutrition of spring wheat under different nitrogen application levels was discussed, which provided the basis for the reasonable fertilization of spring wheat under soil conditions in Hexi Irrigation Area.
