[1月~2月]主要做好播种育苗计划,如购买优质种子,选好适合当地栽培的品种,如耐热性、耐旱性等。同时做好播种容器和播种基质的准备,如基质的配制和消毒处理等。[3月]播种繁殖,可采用室内盆播,种子嫌光性,播后覆浅土,发芽适温19℃~24℃,播后7天~10天发芽,出苗注意间苗,由于黄帝菊自然分枝性好,一般不需要摘心。从播种至开花需9周~10周。[4月]黄帝菊较耐干旱,苗期盆土稍湿润即可,如果土壤过湿,会使苗株下部叶片萎黄和徒长,导致苗株生长柔弱。
[January ~ February] Mainly planted seedlings, such as the purchase of high-quality seeds, select the appropriate local cultivars, such as heat resistance, drought tolerance and so on. At the same time, make preparations for sowing containers and sowing substrates, such as preparation and disinfection of substrates. [March] sowing and breeding, indoor pot sowing can be used, the seeds are too light, after sowing shallow soil, germination suitable temperature 19 ℃ ~ 24 ℃, 7 days after sowing ~ 10 days germination, Good branching, generally do not need topping. From sowing to flowering need 9 weeks to 10 weeks. [April] Yellow Emperor chrysanthemum is more resistant to drought, peat basin seedling can be a little wet, if the soil is too wet, will make the seedling lower leaves chlorosis and leggy, resulting in weak growth of seedlings.
