2017-08-08

盆栽#紫罗兰 的方法:

①品种选择。作为盆栽的紫罗兰,宜选择矮生的重瓣品种为好。在苗期应挑选子叶淡绿色、长椭圆形,真叶边缘缺刻大,呈波状的幼苗,往往多为重瓣花。

②种植盆与土的选择。栽植的盆宜采用盆径在25厘米左右的大盆为好,栽培土宜选用经消毒的疏松、肥沃的培养土,盆底施基肥,每盆种3株。

③浇水与施肥。种植后需浇透水,并放在阴处,3-4天后可放于通风良好的向阳处。在生长期间每隔20天施1次氮饼肥水或液肥,但氮肥不能施得过多,以免徒长,在花蕾期宜施1-2次速效的磷钾肥。由于紫罗兰较耐干旱,浇水不能太勤,见干就浇。

④摘心与采种。待长到9片叶子左右,需进行摘心,促进分枝。植株长到40厘米,需立细竹杆支撑,作为留种的,当角果变黄未开裂前及时采收种子。
