菊花在我国具有悠久的栽培历史,通常春栽秋花。要使秋菊春开,以往一般通过选用晚花品种进行长日照处理来推迟花期;但用这种方法生长期长,费工、成本高。我们的做法是:选用花期早晚不同的品种40多个,在12月上旬将其茎尖组织培养或脚芽扦插繁育的幼苗移栽至温室苗床上或盆缸中。在冬季温室管理时,不增加日照长度,而通过控制土壤水分、增施磷钾肥、增加光
Chrysanthemum in our country has a long history of cultivation, usually in the fall and autumn flowers. In order to make Qiujuchun open, in the past, long-day treatment of late-flowering varieties was generally adopted to delay the flowering period; however, this method has a long growth period, which requires a lot of labor and costs. Our approach is: Selection of more than 40 different varieties of flowering sooner or later, in early December the tip of their tissue culture or foot bud cutting seedlings transplanted to the greenhouse seedbed or basin. Greenhouse management in winter, without increasing the length of sunlight, but by controlling the soil moisture, increased phosphorus and potassium, increasing light
