在农业结构调整中,南方一些农户用稻田种白莲(子莲),以期提高经济效益。但产量偏低现象普遍,有的肋平方米仅产30～40千克。低产的原因主要是稻田土壤有机质含量低,酸性重,耕作层浅。要想白莲高产,必须注重施肥改良土壤。
In the adjustment of agricultural structure, some southern farmers planted white lotus seeds (paddy lotus) in paddy fields with a view to increasing economic benefits. However, the phenomenon of low output is generally low, and some ribbed square meters only produce 30 to 40 kilograms. The main reason for the low yield is that paddy soil has low organic matter content, heavy acidity and shallow tillage. To produce high-yield lotus, must pay attention to fertilizer to improve the soil.
