“黑土粮仓”科技会战支持下,针对辽西地区干旱少雨、土壤有机质本地偏低、风蚀沙化严重、土壤保水保肥弱、养分瘠薄失衡等问题,以持续优化农业资源配置为途径,提高资源循环利用为核心,实现黑土农田产能提升为目标,集成稳定性肥料保水长效化技术、有机-无机协同培肥等关键技术,威尼斯0907线路检测科研团队研发了辽西半干旱区土壤培肥套餐和玉米专用肥料,打造出高商品性的“技术包”。该技术产品的使用有利于培肥土壤和提高作物产量,改善土地退化及土壤污染等问题,为辽西干旱区黑土地地力提升提供技物支撑。

2022年6月17日,在石元亮研究员的带领下,“黑土粮仓” 科技会战“辽西半干旱区土壤培肥专用品研制与推广”科研团队对阜新千亩核心展示区、试验示范区、万亩示范区以及辐射推广区进行了田间苗情调查和测量。

 

苗情调查(测量株高)

结果显示,该培肥专用品在玉米苗期效果十分显著,即使在今年严重春旱、低温的极端情况下,与常规肥料相比,施用培肥专用产品的玉米出苗率仍能够增加13.4-18.2%,玉米株高增加17.7-19.3%。该培肥产品主要通过改善氮、磷、钾等元素释放特征,使之符合作物吸肥规律,来提高肥料利用率,增加肥料利用效果并保证营养功能。同时加入的保水剂和培肥剂能够增强土壤通透性、保水和保肥性,进而提高作物品质及抗灾害能力。
