钾肥是进一步提高向日葵增产潜力的限制因素之一。通过不同钾肥施用量与向日葵主要性状和品质指标的相关性初步分析，以期为黑龙江省向日葵高产栽培技术提供理论依据。研究表明钾肥施用量与向日葵单株籽粒重、百粒重、花盘直径、结实率、粗脂肪含量、蛋白质含量均表现为显著的相关关系（P＜0.05或 P＜0.01)。

Potassium fertilizer is one of the factors which improve the potential of the yield of sunflower. An analysis of the correlation between the different application rates of potassium fertilizer and the main traits of yield and quality of sunflower was made to provide a theoretical basis for the high-yield cultivation technology of the sunflower in Heilongjiang Province. The results showed the increased application of potassium fertilizer was significantly associated to all the traits of the sunflower, in-cluding the grain weight per plant, 100 grain weight, disk diameter, and seed setting rate, crude fat and protein content (P <0.05 or P < 0.01).
