Abstract
[Objective] The purpose was to utilize potassium fertilizer better and supply theoretical basis for enhancing cotton yield and improving fiber quality of cotton.[Method] With variety Xinluzao 13 as test material,the field experiment with potassium fertilizer(N300P150K150) and without potassium fertilizer(N300P150K0)(CK) was conducted in grey desert soil and the effects of using potassium fertilizer on total potassium and nitrogen contents in upper and lower leaves,SPAD of function leaves and cotton yield were studied.[Result] The treatment of potassium fertilization increased total potassium content in cotton leaves in the 20th,40th and 60th d after sowing and that in lower leaves increased 0.14%,0.32 % and 0.11 % respectively in the three periods.The total nitrogen content in cotton leaves in treatment of potassium fertilization reduced in the 40th and 60th d after sowing.Compared with CK,the potassium fertilization increased the SPAD value,enhanced the cotton yield,and reduced the cotton single bell weight,seed index and lint weight of single bell.[Conclusion] The potassium fertilization could promote the growth of cotton,increase potassium content in maturing leaves,stems and buds and the nitrogen content in each organ also increased obviously.
