空心菜喜高温 ,种子萌发需 1 5℃以上的温度 ,蔓叶生长适温 2 5～ 30℃ ,能耐 35～ 4 0℃高温 ,低于 1 5℃以下蔓叶生长缓慢 ,1 0℃以下生长停止 ,遇霜冻茎叶即枯死。因此 ,冬季空心菜必须采用大棚保护种植。空心菜冬季设施栽培的技术 :1　整地作畦　播种前半个月 ,结合犁地每 Rotavidae hi high temperature, seed germination required more than 1 5 ℃ temperature, vine leaf growth suitable temperature 25 ~ 30 ℃, resistant to 35 ~ 40 ℃ high temperature, less than 15 ℃ below the slow growth of vine leaves, growth below 10 ℃ stop In case of frost stems and leaves die. Therefore, the winter mustard greenhouses to protect the planting.
