| Abstract: | Based on the statistical test and variable analysis, the influene on biological character, economic character and cotton yield were researched by applying different level potassium fertilizer and biological potassium fertilizer.The result was that,in the condition that suitable quantity of nitrogenous fertilizer, phosphate fertilizer,potassium fertilizer and management,high yielding could be obtained while 25kg KCL fertilizer per 667hm 2 used in cotton field.2.5kg biological potassium fertilizer, being equal to 20～25kg KCL fertilizer in 667 hm 2 cotton field was better. |
| Keywords: | Cotton Quantity of potassium fertilizer Production |
