Use about 20 grams of rotten dried chicken manure or other fertilizers in each basin, mix them with the basin soil well as the base fertilizer, remove the impurities and gravel, remove the worms and earthworms in the soil, and then put them into the basin. The soil layer generally accounts for about 3 / 5 of the whole basin volume.

栽培温度
Cultivation temperature
碗莲是喜温植物,对温度要求较严,一般8-10摄氏度开始萌芽,14摄氏度藕鞭开始伸长。早期播种时,也要求温度15摄氏度以上,否则幼苗生长缓慢造成烂苗下游地区,4月中旬以前一般不采用露地播种育苗,主要是因为温度这不到种子萌发和幼苗生长的需要。随着温度升高,持续烈日高温(40摄氏度以上),也不利于碗莲的生长发育。22—35摄氏度是碗莲生长发育的最适宜温度。18—21摄氏度时,开始抽生立叶,开花则需要22摄氏度以上,25摄氏度生长新藕,这时需要日温较同,夜温稍低的气候。大多数栽培种在立秋前后气温下降时转入长藕阶段,表现为盆土明显上涨。
