The effects of sulfur and potassium fertilizers on wheat yield and quality have been well studied, but most of them are used as basal fertilizers. However, the root system is senescent at the later stages of wheat growth and cannot absorb sufficient sulfur and potassium fertilizers plant needed. It is still unclear whether sulfur and potassium foliar applications at the later stages can affect wheat yield and quality.

叶面喷施硫钾对小麦籽粒蛋白质品质的影响


硫肥和钾肥对小麦产量和品质的影响已经得到了很好的研究，但其中大多数被用作基础肥料。然而，根系在小麦生长的后期会衰老，无法吸收植物所需的足够硫和钾肥料。目前尚不清楚后期叶面喷施硫钾是否会影响小麦的产量和质量。
