Protealis是专注于非转基因豆类种子及种子技术的欧洲企业,近日宣布其独有的即用型大豆种子接种剂MagNfix™正式上市。此次发布活动在西班牙举行的Euroseeds大会上进行,Protealis在现场为种子经销商和产业合作伙伴举办了MagNfix™发布鸡尾酒会。
目前,欧洲超过90%的大豆消费仍依赖进口[1]。要提高欧洲本土的大豆产量,不仅需要具备适应当地种植条件的大豆种质资源,还必须解决土壤中缺乏大豆生长和蛋白质生产所需菌种的问题。欧洲农业土壤中缺少根瘤菌(Bradyrhizobium)细菌[2],因此农民在播种前必须对大豆种子进行接种处理。
然而,当前的大豆种子接种方法在规模化农场应用中仍难以实现稳定一致的效果。Protealis首席执行官Benjamin Laga:″尽管欧洲大豆种植在遗传育种方面已取得显著进展,但接种环节仍存在重大挑战。无论是在工厂还是在农场应用,许多现有的方法常依赖于不适应欧洲本地土壤的热带细菌菌株,这些菌株难以储存或运输,且施用不均匀。此外,大多数接种剂的保质期比较短;活菌必须在播种前1至2天内使用,否则会迅速失去功效。这使得大规模接种难以执行,也限制了农民所能实现的产量和蛋白质生产潜力。
MagNfix™包膜技术[3]可使细菌保持活性,施用在种子上后在90天内仍能发挥与新施用相当的效果[4]。在多地点独立试验中,与对照接种剂相比,MagNfix™平均增产31%,蛋白质含量提高7%[5]。类似的田间试验数据显示,经MagNfix™包膜的种子在储存一个月、两个月或三个月后播种,其产量和蛋白质含量与刚包膜后立即播种的种子相比,无统计学上的显著差异[6]。
MagNfix™将通过欧洲的大豆种子经销商,以即播型大豆种子提供。MagNfix™已列入德国及欧洲FiBL投入品清单,因此该产品既适用于有机农业,也适合常规种植的农户使用。

Results showed no statistically significant difference in yield and protein content between seed coated with 1, 2, or 3 month old MagNfix™ before planting, versus seed coated immediately before planting. Performance may vary with storage conditions, seed treatment practices, and environmental factors.
