寄生杂草种类繁多,分布广泛,其主要依靠吸取寄主植物的养分生活,抑制作物正常生长,严重影响农业生产。近年来寄生杂草的治理受到越来越广泛的关注。为此,综述了我国主要寄生杂草的种类及其危害,并分别从化感作用、计算机技术、化学农药、生态位理论等方面阐述了寄生杂草的防治。对寄生杂草研究的发展趋势进行了展望。 A wide range of parasitic weeds, widely distributed, which mainly rely on the nutrient absorption of host plant life, inhibit the normal growth of crops, seriously affecting agricultural production. In recent years, the management of parasitic weeds has attracted more and more attention. In this paper, the types of the major parasitic weeds in our country and their harm were summarized. The prevention and treatment of parasitic weeds were described from the aspects of allelopathy, computer technology, chemical pesticides, niche theory and so on. The development of parasitic weed research is forecasted.
