摘　　要：除草剂的广泛使用引发了环境污染、生物多样性减少、杂草群落变迁和杂草抗药性等诸多问题。热除草方法是替代化学除草的潜在方法,热除草方法有火焰除草、热水除草、蒸汽除草、红外辐射除草、激光除草等。热除草是快速加热植物体内的水分使植物细胞破裂失去活性、死亡的方法。各种热除草技术的传热机制不同。重点介绍了各种热除草技术的机理和在国内外的发展现状及所适用的环境和发展方向。随着有机农作的发展,热除草技术将发展成熟并得到广泛应用。Using of herbicide has caused a good many of serious problems such as environment pollution,decrease of biological diversity,changes in the weed community,and resistance of weeds to herbicides.Thermal weed control is an alternative to chemical herbicides.Now there are a lot of thermal weed control methods,including flame weeding,hot steam weeding,hot foam weeding,infrared radiation weeding and laser weeding.Thermal weed control is a way by raising the temperature of the moisture,so that the cells of the plant will rupture,lose the activity and die at last.Thermal weed control methods vary in heat transfer mechanism.Principle of the thermal weed control technologies was introduced in the paper.The use of the thermal weederes was discussed.With the developing of organic farming,thermal weed control technologies will develop to a high level of sophistication and be applied widely.
