花盆内的泥土较少,肥料有限,不能满足花卉在生长中的营养需求,这就需要养花者根据不同的花木生长阶段,增施不同的肥料。一般来说,观叶花木,在生长期,只要施一、二次以氮肥为主的肥料(10～15天施一次)就足够了;观果观花的花木所需的肥料较多,在长枝叶时,施一、二次以氮肥为主的肥料,在花芽分化、长花蕾和开花前,应增施以磷肥为主的肥料。特别是一年之中连续多次开花的花木,如木兰、茉莉、月季、石榴等木本花卉,要多施几次以磷肥为主的肥料,不然则会影响开花次数。对于一年中仅开花一次的花卉如杜鹃、茶花、菊花等 Fewer pots and limited fertilizers in the pot can not meet the nutritional needs of the growing flowers. This requires the planter to add different fertilizers according to the different stages of vegetation growth. In general, foliage trees, in the growing season, as long as the first and second nitrogen-based fertilizers (10 to 15 days once applied) is sufficient; view of flowers and trees need more fertilizer in the When long branches and leaves, the first and second nitrogen-based fertilizer, flower bud differentiation, long buds and flowering, fertilizer should be increased by the main fertilizer. In particular, flowers blooming many times in a year, such as magnolia, jasmine, rose, pomegranate and other woody flowers, should be applied more frequently with phosphate-based fertilizers, otherwise they will affect the flowering number. Flowers blooming once a year such as rhododendron, camellia, chrysanthemum, etc.
