巴戟属热带、亚热带植物,喜欢温湿,害怕寒冷。如遇低温霜冻轻则停止生长,重则死亡。所以,防止巴戟冻害是一项增产保收的重要措施。一、灌水冬天,在吹干冷风期间,应及时浅灌,既能提高土温,又可增强根系对养分的吸收,使植株长得健壮,提高抗寒能力。二、覆盖在霜降到来前夕,要用稻草、芒草或薄膜遮盖植株,防止霜冻为害。但要做到日揭夜盖, Morinda is a tropical, subtropical plants, like warm and humid, afraid of the cold. In case of low temperature frost light stop growth, heavy death. Therefore, to prevent frostbite halberd is an important measure to increase yields. First, the irrigation in winter, during the dry cold wind, irrigation should be promptly, both to increase soil temperature, but also enhance the root absorption of nutrients to make plants grow robust and improve the ability of cold. Second, covering the eve of the arrival of frost, straw, grass or film covered with plants, to prevent frost damage. But to do the night cover,
