栽培土壤
Cultivated soil
碗莲要求含腐殖质较丰富的塘泥或稻田泥作栽培土,切忌用工业污染土。黄泥粘度大,使用量要适当,过粘会影响藕鞭的伸长和藕的膨大;沙质土疏松,粘性不够,容易遭风害而折损,有碍于根系的生长,一般以黄泥、沙质土按7:3的比例混合使用为宜。如无沙质土,可加黄沙,但比例要略小些。城市郊区,可直接选用蔬菜地的园土;城市中还可用春季盆花换盆的宿土加一半的黄泥作栽培土。
The pond mud or paddy field mud with rich humus is required to be used as cultivation soil, and industrial pollution soil should not be used. Yellow mud has a large viscosity and should be used properly. Excessive viscosity will affect the elongation of lotus rhizome and the expansion of lotus root. Sandy soil is loose and not sticky enough, which is easy to be damaged by wind and hinders the growth of root system. Generally, it is suitable to use yellow mud and sandy soil in a ratio of 7:3. If there is no sandy soil, yellow sand can be added, but the proportion is slightly smaller. In the suburb of the city, garden soil of vegetable field can be directly selected; in the city, the old soil of potted flower changing basin in spring and half of yellow mud can be used as cultivation soil.
每盆用20克左右的腐熟干鸡粪或其他肥料,与盆土充分拌匀作基肥,拣去其中的杂质和石砾,清除土中的小虫和蚯蚓,然后放入盆中。土层一般占全盆容积的3/5左右。
