通过盆栽和大田试验在石河子灌耕灰漠上棉田进行了棉花施钾及磷钾肥配合试验。研究表明，施钾肥可以提高棉花生理活性和抗逆性，表现在提高棉花叶片叶绿素含量、净光合速率及干物质积累量，并提高对水分胁迫的适应性。但钾肥对棉花产量、经济性状和品质均没有产生明显的影响。
Through the pot and field experiments in Shihezi gray cotton fields on cotton fields were carried out with potassium and phosphorus-potassium fertilizers. The results showed that application of K fertilizer could increase the physiological activity and stress resistance of cotton, which showed that it increased the chlorophyll content, net photosynthetic rate and dry matter accumulation of cotton and increased the adaptability to water stress. However, potash fertilizer had no significant effect on cotton yield, economic traits and quality.
