摘　　要：为了探究藠头有害生物无害化防控技术,在江西省新建县生米镇开展了藠头太阳热土壤消毒试验。结果表明：太阳热土壤消毒能明显减轻草害,对土传病害及地下害虫的防控达到种藠化学消毒的同等效果;藠头单株叶数、分蘖数、叶重及鳞茎重等均有所增加,藠头鳞茎产量和生物产量分别比对照提高10.2%-15.0%和9.7%-19.5%。To study the unharmful prevention and control technology of pests in Allium chinensis, the experiment in soil disinfection with solarization was performed in Shengmi town, Xinjian county, Jiangxi province. The results showed that soil disinfection with solarization could significantly reduce the damage of the weeds, and its control effect on soilborne diseases and underground insect pests was the same as that of seed - bulbs chemical disinfection. After soil disinfection with solarization, the leaf number, tiller number, leaf weight and bulb weight per plant all increased to a certain extent, the bulb yield and biomass of Allium chinensis were increased by 10.2% - 15.0% and 9.7% - 19.5% respectively as compared with the control.
