"咱选用的是大穗大粒优良品种，只是缩小了行距，播量不增加，单株间株距分布更均匀，只要拔节前 做好防控，后期应用栽培技术调整群体结构、促进通风透光，就能预防虫害、增加茎秆粗壮度抗倒 伏。"桑伟耐心解释道。 三 微风掠过南疆大地，四十二团四连的一块玉米地里，收割后的秸秆在阳光的暴晒下，闪着金黄色的光 泽。 就是这块高产田，不久前刷新了全国复播玉米高产纪录，实现"冬小麦+复播玉米"一年两熟周年亩产 1956.18公斤的好成绩。 "'两吨田'这个目标具有极大的挑战性。"新疆农垦科学院研究员桑志勤说，根据南疆粮食作物产量水 平，要实现"两吨田"目标，复播玉米平均亩产就要达到1.2吨。 近年来，为进一步落实国家粮食安全战略，兵团党委提出推动"一年两熟"种植模式、力争实现大面 积"吨半田"和小面积"两吨田"目标。新疆农垦科学院集中优势科研力量，积极开展高产创建示范工作。 盛夏，阳光炽热，冬小麦进入扬花灌浆期。 "小麦花期比'昙花一现'还短暂。每一朵小麦花的完美闭合，都预示着将孕育出一粒饱满的麦子。"桑伟 说。 2025年6月，新疆气温陡然升高，桑伟顶着烈日，带领团队指导种植户在小麦扬花后加紧喷施磷酸二氢 钾和杀虫杀菌剂，帮 ...

扬子晚报网12月3日讯(通讯员王悦杨安康记者陈咏)玉米—大豆带状复合种植，是一种高效集约种植模式，在稳定玉米产量的同时增收一季大豆，对保障 粮食安全具有重要意义。然而在实际生产中，玉米植株高大易遮挡阳光，导致下层大豆受光不足，产量难以提升。记者3日从扬州大学获悉，大豆和玉米 间套种实现"双丰收"的难题，被该校生物科学与技术学院熊飞教授团队攻克，相关研究成果近日发表于国际知名期刊《Plant,Cell&Environment》。 细致研究 据悉，团队还从大豆体内1029种代谢物中，鉴定出3个"关键增产物质"：邻苯二甲酸(PA)、香草酸(VA)和大黄素-8-葡萄糖苷。其中，PA有助于促进大豆根 系发育、增强抗逆性，使其在遮荫环境下仍能有效吸收养分、抵御逆境；VA可优化大豆分枝结构、增强茎秆强度，防止倒伏。这些物质协同作用，通过 调控作物代谢关键通路，精准满足大豆在遮荫条件下的生长需求，实现养分高效利用。 "将籽粒代谢物与间作系统产量形成机制直接关联，还是第一次。"熊飞教授表示，这些代谢标志物不仅可用于早期预测大豆产量潜力，还能指导针对性品 种选育，培育更适合与玉米间套作的大豆新品种。该研究既解决了玉米遮荫导致大豆 ...
