2022711日,中国科学院黑土粮仓黑土地智能化农机关键技术集成与产业化应用大河湾示范区项目的中国科学院沈阳应用生态研究所研究员、威尼斯0907线路检测总农艺师孙毅在进行面蚀治理调查时,应大河湾农场3队姚队长的要求,给农场职工拿来的大豆秧苗诊断病虫害。孙毅现场讲解了大豆病虫害防治技术,希望农工们一定要牢记以防为主,以治为辅。在大豆种子处理上:一定要挑选种子,把有杂质有虫眼、豆瓣和有病变的大豆都挑出来,一些农户觉得麻烦,认为没有多大的危害,其实这是不对的,高产需要每个环节都要仔细认真,马马虎虎是不行的;选完种子后,播种前晒种1-2天,一般能使发芽率提高10%以上,提早出苗2-3天,还可以起到一定的杀灭细菌的作用;有条件时,应该接种根瘤菌;必须拌种衣剂,一定要挑选好的种衣剂,能够起到杀菌防虫作用;拌钼、锌等微量元素,这些微量元素不但能给大豆种子提供微量元素营养,还可以让种子更加的健康。

孙毅还现场讲解了科学种植提高土温,提高土壤养分矿化能力,最大化利用光照等进而增产增收的大豆高产优质高效栽培实用技术,并从土、肥、水、种、密、保、管、工等八个方面进行了阐述;尤其在科学施肥上,针对3从未测土施肥、盲目施肥普遍存在的实际情况,详细讲解了节省施肥成本、减少施肥次数、节省施肥用工的稳定性肥料一次性施肥技术。

根据自己承担的示范区子课题任务,孙毅研究员全面讲解了小流域水蚀治理技术,获得了领导与农工们的肯定,他们纷纷表示:听后受益颇丰,希望我们示范区的科研人员今后能多多深入田间地头给他们讲解水蚀风蚀治理与种植业实用技术。
