绿豆(Vignaradiata(L.)Wilczek)、豇豆(VignaunguiculataL.)、小豆(Vignaangularis(willd)OhwiOhashi)是我国北方旱作区主栽的粮、菜兼用作物,在适宜的环境条件下萌发生长良好,但由于北方春季普遍干旱,严重影响了三种豆类的生产。本文研究了模拟干旱条件下三种豆类种子吸水萌 Vigna diura (L.) Wilczek, Vignaunguiculata L., and Vignaangularis (willd) Ohwi Ohashi are the main crops and vegetable crops in the northern part of China. They germinate and grow well under the suitable environmental conditions, however, Due to the general drought in the northern spring, the production of three types of legumes has been severely affected.
