油葵具有生育期短、高产、高油、耐干旱、适应性广等特点,油葵油营养丰富,富含亚油酸,与其它油料作物相比具有明显的优势。2016年邢台市种植面积达到1.4万公顷,油葵已成为特色农业中的一大亮点。但是在传统种植中常常存在盲目施肥现象,尤其是忽视钾肥。为探明不同钾肥用量对油葵的增产效果,为油葵科学合理施肥提供依据,在邢台市潮土区开展了油葵钾肥施用效果试验研究。一、材料与方法1、试验材料
Sunflower has the characteristics of short growth period, high yield, high oil, drought resistance and wide adaptability. Sunflower oil is rich in nutrients and rich in linoleic acid and has obvious advantages over other oil crops. Xingtai City in 2016 planted area reached 14,000 hectares, sunflower has become a highlight of characteristic agriculture. However, blind fertilization often occurs in traditional cultivation, especially in potash. In order to find out the effects of different K dosage on the yield of sunflower and provide the basis for scientific and rational fertilization of oil sunflower, the experiment on the effect of potassium fertilizer on sunflower was carried out in the fluvial area of Xingtai.
