细小的花卉种子播种时需要掌握一定的技术。除了具体的播种操作外,了解种子的特性及其所需的温度、湿度、土壤等,也是非常关键的。比如:大岩桐等种子需高温播育,即水浸后应立即放在25～28℃的地方,如搁置低温处1～2天,就可能使种子烂掉,一苗不出。花毛莨的特性则是需低温育苗,一般为8℃左右,超过12℃便难以出苗。总之,细小种子对外界的适应能力差,抵抗力弱,播种一定要精心细致。现将有关方法介绍于下:
Small flower seeds need to master a certain technology when sowing. In addition to specific seeding operations, understanding the characteristics of the seed and its required temperature, humidity, soil, etc. is also critical. For example: Sinning and other seeds need high temperature sowing, that is, immediately after flooding on the 25 ~ 28 ℃ place, such as shelving low temperature for 1 to 2 days, it may make the seeds rot, a seedling not. Flower Ranunculus is the need for low-temperature nursery, usually about 8 ℃, more than 12 ℃ will be difficult to emerge. In short, the ability of small seeds to adapt to the outside world is poor, weak resistance, planting must be meticulous. Now the method introduced in the following:
