芹菜播种前应预先做好种子处理,以提高种子净度、发芽率和发芽势,使其出苗整齐、茁壮。芹菜种子处理,除使用一些通用种子处理法外,还应分析其种子特点,采取相应的综合技术措施,才能达到目的。一、芹菜种子特点。这是其形态特征和所含化学成分决定的,主要是: 芹菜果为双悬果,成熟时沿中缝裂开两半,半果各悬于心皮上,不再裂开。半果近似扁圆形,各含一粒种子。在生产上播种的“种子”实际上是果实。果实内有挥发油,外表有革质,透水性差,发芽慢。芹菜种子非常小,暗褐色,椭圆形,横切面为正五角形,表面有纵纹,无茸毛,有浓香味,千粒重0.41克,每克为2500粒左右。
Celery sowing should be done beforehand seed treatment to improve seed purity, germination rate and germination potential, so that it emerges neatly, robust. Celery seed treatment, in addition to using some common seed treatment, but also the analysis of the characteristics of their seeds, to take the appropriate comprehensive technical measures to achieve their goals. First, the characteristics of celery seeds. This is the shape and composition of its chemical composition decisions, mainly: celery fruit as double-hanging fruit, mature along the slit in the middle split two and a half hanging on the carpels, no longer cracked. Approximately flat half round fruit, each containing a seed. Sowing seeds in production is actually fruit. There are volatile oil inside the fruit, the appearance of leathery, poor water permeability, germination slow. Celery seeds are very small, dark brown, oval, cross-section is a positive pentagon, the surface has vertical stripes, no hair, a strong fragrance, grain weight 0.41 grams, 2500 grams per gram.
