半枝莲的种植方法?
半枝莲的种植方法,半支莲株高30~40厘米。茎下部匍匐生根,上部直立,茎方形、绿色。叶对生,叶片呈三角状卵形或卵圆形,边缘有波状钝齿,下部叶片较大,叶柄极短。花小,2朵对生。花期为5~6月,果期为6~8月。
半支莲喜温暖湿润的气候,对土壤条件要求不高。野生多见于沟旁、田边及路旁潮湿处,过于干燥的土壤不利半支莲生长。半支莲一般栽培3~4年后,植株开始衰老,萌发能力减弱,必须进行分株另栽或重新播种。种子容易萌发,发芽适宜温为25℃,种子寿命为1年。
以种子繁殖为主,也可用分株繁殖。
①种子繁殖多直播,时间于9月下旬至10月上旬,条播或穴播。条播按行距25~30厘米开沟,沟深4厘米左右;穴播者按穴距27厘米左右开穴。播种时,先将种子撒人混有肥料的草木灰里,拌成种子灰,再均匀地撒人沟内或穴内,覆一层细土或草木灰,厚度不得超过0.5厘米。播后在出苗前要绝对保持土壤湿润,播后约20天即可出苗。
②分株繁殖春夏进行。将植株老根挖起,选健壮、无病虫害植株进行分株,每株有苗3~4根,按穴距27厘米左右穴栽,栽后浇水,以上就是关于半枝莲的种植方法的介绍。
