一种当归种植用地膜覆盖装置
本技术属于中药种植设备领域,具体涉及一种当归种植用地膜覆盖装置。
技术介绍
当归,为伞形科植物当归Angelicasinensis(Oliv.)Diels的干燥根。主产甘肃东南部,以岷县产量多,质量好,其次为云南、四川、陕西、湖北等省,均为栽培。具有补血活血,调经止痛,润肠通便之功效。常用于血虚萎黄,眩晕心悸,月经不调,经闭痛经,虚寒腹痛,风湿痹痛,跌扑损伤,痈疽疮疡,肠燥便秘。酒当归活血通经。用于经闭痛经,风湿痹痛,跌扑损伤。采用种子繁殖是当归繁殖最为直接的繁殖方式。地膜覆盖栽培的最大效应是提高土壤温度,春季低温期间采用地膜覆盖白天受阳光照射后,0-10厘米深的土层内可提高温度1-6℃,最高可达8℃以上。进入高温期,若无遮阴,地膜下土壤表层的温度可达50-60℃,土壤干旱时,地表温度会更高。但在有作物遮荫时,或地膜表面有土或淤泥覆盖时,土温只比露地高1-5℃,土壤潮湿时土温还会比露地低0.5-1.0℃,最高可低3℃。夜间由于外界冷空气的影响地膜下的土壤温度只比露地高1-2℃。地膜覆盖栽培可以提高地表温度、保湿和抑制杂草生长的优点,但是 ...
