“四控行动”指:一是通过测土配方施肥、增施有机肥、机械施肥等技术措施，化肥减量，实现控肥增效;二是通过种子消毒;机械膜间除草;起垄高畦栽培，减少田间湿度;整枝打杈前后喷施保护性低毒农药，预防传播病菌;施用农药增效剂减药10%~20%;利用黄蓝板诱杀蚜虫、蓟马等害虫，杀虫灯诱杀成虫等物理诱控技术。农药减量，实现控药减害;三是采用开沟起垄，垄沟覆膜保水，用水减量，实现控水降耗;四是使用国标地膜，残膜回收，实现控膜提效。
"Four Control Actions" Ensures the Annual Output in Inner Mongolia
"Four control actions" refer to: 1. Reducing the amount of chemical fertilizer through technical measures such as conducting soil testing to determine appropriate fertilizer formulas, increasing organic fertilizer and mechanical fertilization, so as to realize fertilizer control and increase efficiency. 2. Through seed disinfection, mechanical intermembrane weeding and ridges cultivation to reduce field humidity; Spray protective low toxicity pesticide before and after pruning to prevent transmission of germs; Apply pesticide synergist to reduce the dosage by 10%~20%; Use yellow and blue plate to trap aphid, thrips and other pests, use insecticidal lamp to trap imagoes and apply other physical control technologies; Reduce pesticide dosage to realize drug control and harm reduction. 3. Use furrows and ridges, plastic-film mulching on ridges and furrows to protect water and reduce water consumption to achieve water control and consumption reduction. 4. Use national standard mulching film and recycle residual film in order to achieve the effect of control film.
获悉，内蒙古自治区在2020年粮食播种面积10250万亩、产量732.8亿斤的基础上确保今年粮食生产稳定发展，努力实现粮食播种面积不减、产量不降，依靠科技提高单产、提升产能。2021年，内蒙古自治区将继续全面推广“四控”措施，集成推广一批绿色高质高效生产栽培技术模式，农药化肥使用量持续保持负增长。调整优化主要作物区域布局和种植结构，增加更多优质绿色农产品供给。
近年来，内蒙古自治区通过与中国农业科学院、西北农林科技大学等科研院所“产学研用”联合科研攻关，开展控肥增效、控药减害、控水降耗、控膜提效工作，加大源头控制力度，助推农业绿色高质量发展。“十三五”以来，内蒙古针对农业面源污染治理和农业资源节约，全面推进“四控”行动，全区水肥一体化面积达到2320万亩，无膜浅埋滴灌901万亩，测土配方施肥技术覆盖率达到90%以上，绿色防控、统防统治面积分别达到4410万亩和4660万亩，化肥农药利用率均达到40%以上，化肥农药使用量自2018年起实现持续负增长；生产标准化快速推进，全区连续3年实施生产标准化行动计划，围绕玉米、马铃薯、大豆、向日葵、蔬菜等主要作物提标扩面、提质增效，集中连片实施标准化生产的旗县区已达到82个，7种作物标准化生产面积达到7087.3万亩，标准化技术覆盖率达到66.3%，自治区主推标准达到295项，主要农作物生产标准体系基本形成；持续强化技术集成和组装配套，推广应用了无膜浅埋滴灌、盐碱化耕地改良“五位一体”技术模式、玉米大豆带状复合种植、大豆大垄密植浅埋滴灌栽培、水稻旱作、智能配肥、玉米新型除草剂等新技术、新产品，部分技术处于国内领先水平，为种植业绿色高质量发展提供了强有力的科技支撑。(雨林)
