6栽培学研究慈姑栽培主要集中在长江流域及其以南各省，尤其是江苏太湖及里下河地区具有悠久的栽培历史，因而这些地区积累了丰富的栽培经验。曹侃、赵有为等（1962）较早地用刮老乌和苏州黄作为试验材料对慈姑的生物学特性及丰产栽培技术进行研究，提出了丰产栽培技术的五项措
Cultivation research Sagittaria cultivation is mainly concentrated in the Yangtze River Basin and its southern provinces, especially in Jiangsu Taihu Lake and Lixiahe area has a long history of cultivation, so these areas have accumulated rich experience in cultivation. Cao Kan and Zhao Youwei et al. (1962) earlier studied the biological characteristics and high yield cultivation techniques of Sagittaria scoparium with Scopolaranthus quinquecium and Suzhou Huang, and proposed the five measures of high yield cultivation
