豆薯引种及高产栽培技术研究初报

Preliminary Study on Introduction and High Yield Cultivation Techniques for Pachyrhizus erosus Urban

通过调查豆薯的生物学特性,获得其在山东烟台的生长发育规律和适宜的栽培方式。结果表明:豆薯在烟台地区适宜生长期在5月中旬至10月中旬;露地直播栽培以5月中旬为好,覆盖地膜栽培可提早10d;栽培方式以地爬式产量较高,并节省成本,种植密度为起垄单行栽培,行距50～60cm、株距15～20cm。

By investigating the biological characteristics of Pachyrhizus erosus, the law of growth and development in Yantai was obtained. The results shouwed that the suitable growing season was between mid-May and mid-October, the ideal time for direct seeding in open field was mid-May, It could achieve a harvest of 10 days earlier by way of mulching cultivation,way of climbing cultivation had the highest yield, and could save the cost,planting densily was ridging separate cultivation, the single row plantingwith a plant density was 50-60 cm （row spacing）×15-20 cm （plant spacing） .
