- 摘要:
- 大豆胞囊线虫是一类重要的植物病原线虫,常规药剂难以防控,对我国大豆生产造成了巨大的影响。生物防治和作物抗性诱导技术是目前大豆胞囊线虫防治较为切实可行的方法,本文研究了生防药剂“禾力素”的药效及其不同处理方式(叶面喷施和种子包衣处理)对哈尔滨地区不同时期连作大豆产量及胞囊线虫抑制效果的影响。结果表明:禾力素两种处理方式均能够有效抑制胞囊线虫生长,减少大豆根系胞囊发生,并对大豆生长发育具有显著的促进作用,大幅提高大豆产量,是一种防控大豆胞囊线虫发生的理想药剂。
- Abstract:
- Heterodera glycines is an important world-wide plant-pathogen nematode which could cause severe loss to soybean production, therefore, the control of its spreading becomes imperative. Earlier used approach seems to be inept in controlling its outbreak. In this regard, bio-control and crop resistance induction technology seem to be versatile tool in preventing Heterodera glycines infection.Thus, we studied the fungicide inhibition effect on cystic nematode of a bio-control agent Helisu and its different treatments (foliar spraying or seed coating treatment) on continuous cropping soybean at different growth stages in Harbin to notice its effects on yield and Heterodera glycines resistance. The findings showed that the application of Helisu could efficiently inhibit Heterodera glycines infection and decrease the formation of cyst in soybean roots.In addition, study also confirmed the positive impacts of Helisu, the treatment during early growth stage could stimulate the overall growth and development of soybean plants, which boost its yields significantly.Therefore, we propose that Helisu is an ideal agent to control Heterodera glycines infection.
