本发明公开了一种设施果树根域土壤双向温控促早栽培方法。方法步骤为,在果树行间距地表30~50cm根系集中分布层埋设包括热源设备和冷源设备的土壤温度调控装置及温度传感器,构建双向温控系统。休眠期根域土温降至10~15℃时启动冷却梯度降温,每周降1~2℃至0~10℃,环境与根域温差0~3℃;地温稳定降至7℃起按0~7.2℃模型累计需冷量,达标且芽体萌动时判休眠解除。后启动加热每周升2~3℃至12~13℃,按萌芽、花期、幼果至膨大期分别调控根域土温于12~13℃、13~17℃、20~22℃,超22℃时常温水循环降温。本发明实现地上与根域温度协同,解决了设施促早栽培中根芽发育不同步的生理失调问题,果实安全,可自动化运行。
