研究了不同钾水平处理下的棉籽成分与品质．结果表明：施钾能促进光合产物向棉籽运输，增加棉籽的百粒重，从而大大提高棉花种子的活力和发芽率；钾能显著提高棉籽仁中粗脂肪含量和不饱和脂肪酸的比例，降低蛋白质含量，有利于油脂品质的提高；但施钾可明显提高棉籽中有毒物质棉酚的含量，这对棉籽的综合利用是个不利因素．
The cottonseed composition and quality under different potassium levels were studied. The results showed that applying K could promote the transport of photosynthetic products to cottonseed and increase the 100th weight of cottonseed, which greatly enhanced the vigor and germination rate of cottonseed. K could significantly increase the proportion of crude fat and unsaturated fatty acids in cotton seed kernel, Content, is conducive to the improvement of oil quality; However, potassium can significantly increase the cottonseed toxic substances gossypol content, which is the comprehensive utilization of cottonseed is a negative factor.
