一、水养风信子的种球选择在无病虫为害、无机械损伤的前提下,选择种球应考虑以下几点: 1.种球的花芽分化状况:用于水养的种球,必须具备分化完全的花芽,并已通过低温阶段。因为只有在20℃～28℃条件下(约30天)完成花芽分化、又经过60～80天13℃以下低温期的种球,才能正常开花。这一过程可以自然完成。但家庭水养往往要改变风信子花期(如使其春节开放等),所以必须选择经过人工处理的种球。
First, water hyacinth seed selection In the absence of insect pest damage, no mechanical damage under the premise of the choice of bulbs should consider the following points: 1. Bulb flower bud differentiation status: used for hydroponics bulbs, must With complete differentiation of flower buds, and has passed the low temperature stage. Because only at 20 ℃ ~ 28 ℃ conditions (about 30 days) to complete the flower bud differentiation, and after 60 to 80 days 13 ℃ the following low-temperature bulbs, to flowering normally. This process can be done naturally. However, domestic hydroponics tends to change the flowering period of hyacinths (for example, opening up the Spring Festival) and must choose artificial bulbs.
