石榴花分结果的筒状花和不结果的钟状花两种。石榴的钟状花约占85％,是造成石榴树开花多坐果少 的主要原因。生产中只要采用科学的花果管理技术,就能提高其坐果率,实现丰产丰收。 1.花前追肥。石榴开花前(4月中下旬),每株追施尿素0.25～0.5kg,或于始花期全树喷0.3～0.5％的尿素1～2遍,能提高筒状花质量,提高坐果率。 Pomegranate sub-results of tubular flowers and not the results of two bell-shaped flowers. Pomegranate bell-shaped flowers account for about 85%, is the main reason for the pomegranate tree flowering less fruit. As long as the production of scientific and technological management of flower and fruit, it can increase their fruit setting rate, to achieve high yield harvest. 1. Flower top dressing. Pomegranate before flowering (late April), each topdressing urea 0.25 ~ 0.5kg, or at the beginning of flowering 0.3 ~ 0.5% of the whole tree spray urea 1 ~ 2 times, can improve the quality of tubular flowers and improve fruit set rate.
