近几年来,随着我国农业产业结构的调整,蔬菜播种面积和复种指数不断提高,但由于种植品种单一,耕地面积有限,造成轮作和倒茬困难,根结线虫病危害日趋严重。同时,它能使真菌和细菌易于侵染植物,引发其他病害的发生,严重影响了蔬菜的产量和质量。在田间实验和综合调查的基础上,对蔬菜根结线虫的分类学地位、发生规律、病原特点、为害症状及综合防治措施进行了总结归纳,并针对蔬菜根结线虫的危害特点,提出切实可行的综合防治措施。
In recent years, with the adjustment of agricultural structure in our country, the sown area of vegetables and the index of multiple cropping have been continuously improved. However, due to the single variety of cultivated land and the limited cultivated land, the crop rotation and upside down are difficult, and the root knot nematode disease is becoming more and more serious. At the same time, it can make fungi and bacteria easy to infect plants, triggering other diseases, seriously affecting the yield and quality of vegetables. Based on the field experiment and comprehensive investigation, the taxonomic status, the occurrence law, the pathogenic characteristics, the damage symptoms and the comprehensive prevention and cure measures of root-knot nematode were summarized and put forward feasible for the root-knot nematode hazards Comprehensive prevention and control measures.
