在净作玉米不断刷新产量新高的同时,大豆玉米带状复合种植模式,让同一块土地挖掘出更大产能,解锁山地农田“一亩地两份收成”的可能。
早在9月1日,省农业农村厅组织专家对遵义市桐梓县九坝镇白盐井村大豆玉米带状复合种植百亩方进行现场测产。
专家组在示范区随机抽取上中下3块代表性地块实收实测,大豆平均亩产115.26公斤,玉米平均亩产557.96公斤,达到了“玉米不减产,增收一季豆”的示范效果。
“大豆玉米带状复合种植高产竞赛示范片的成功实践,充分证明了该技术模式在提高土地利用率、提升粮油综合产能方面的巨大潜力,为我省相似生态区域大规模推广应用提供了宝贵的技术经验和数据支撑。”省农作物技术推广总站相关负责人介绍。
示范区大豆品种为黔豆12,玉米品种为正大659。“黔豆12是我省自主选育的品种, 为山地种植的‘全能选手’,高产广适应,可与玉米等高秆作物间作,实现空间互补、优势叠加,让一亩地发挥出双倍的效益。”省农科院油料研究所大豆花生研究室主任陈佳琴介绍。
下一步,我省将认真总结高产竞赛成功经验,持续深化“四良融合、一增五改”技术推广。同时持续优化大豆玉米带状复合种植标准化规程,以科技赋能筑牢粮食安全屏障,全力推动全省粮油产业高质量发展。
