一般在10月中下旬播种。选粒大饱满、色泽鲜艳、无病虫害的种子，667m2用种4－5kg。播前晒种1-2d，干籽直播。播深2－3cm，播后覆土。矮生种按30cm×(30-35)cm开穴，每穴点播4-5粒，出苗后留苗3-4株。蔓生种单行密植时，按(25-30)cm×(1oo-120)cm开穴；双行密植时，按30cm×70cm(畦宽1.4m)开穴，每次4粒，出苗后留苗3株。
四、温度控制
播种后加强温度管理，促进发芽。播种至出苗(子叶展开)保持土温12℃－13℃以上，气温20℃－25℃；子叶展开后降至15℃－20℃；伸蔓期20℃－25℃；开花结荚期20℃－22℃．夜温10℃－12℃。植株在高于32℃、低于10℃时生育不良，易引起落花落荚。注意通风，调节温湿度，减少有害气体积累，防止发病。
五、肥水管理
苗期一般不灌水，至开花结荚前控制灌水量，以免引起徒长，但过分干燥对芸豆生长不利。结荚后增加灌水量，保持湿润。2片真叶展开后、花芽开始分化时，667m2追施翠姆三元肥kg。开花结荚初期，667m2追加尿素15－20kg，盛期再追尿素25—30kg，追肥应深施埋严并浇水。
六、植株调整
蔓生芸豆在伸蔓后及时插架和引蔓上架。矮生芸豆在密植情况下，节间较长，植株较高。在温室应利用立柱、拉横线引侧枝，以改善光照，防止倒伏。温室芸豆在生长中后期，及时去除下部老黄叶，再追肥1－2次，既可改善通风透光条件，又能促使新侧枝生长，主蔓顶端的潜伏芽也可因营养条件的好转继续开花结荚。这样可延长采收期半月以上，增产20％－30％。
七、减少落花
落荚 芸豆的花量很多，每一花序可着生4－15朵，但成荚率很低，只占开花数的20％－30％。欲提高结荚率，在合理运用栽培措施的基础上，还应在开花期用(5－20)×106的防落素或15×10-6的吲哚乙酸等激素喷花，可明显减少落花。
八、适时采收
一般矮生芸豆播后50－60d采收，收获期1个月左右。蔓性芸豆播后65－80d采收，陆续采收2个月左右。当花后10－15d，豆荚基本长成，豆粒略显，荚壁未硬化时，即可采收嫩荚。若采收过晚，纤维增多、品质降低。一般2－4d采收1次，或根据市场需要及时采收。667m2产嫩荚1000－1500kg，高产达3000kg以上。
大棚种植芸豆，可以错季上市，比如在元旦及春节前后上市，打好时间差，获得更好的价格，给种植户带来更好的种植效益。
大棚芸豆长到13厘米的话，可以充肥了，因为冲肥的标准就是在13厘米以上，那么包括13厘米的话，都是可以进行充肥的标准的
