玉米后期防病增产，飞防新蓝海

导读：7月22日，在辽宁昌图县后窑镇船房村，昌图慧飞科技植保队在当地设立对照示范田，给 50 多亩玉米地进行增产和杀菌作业。

　　【农机网 明星企业】这两年随着玉米价格节节高升，不少农户转向玉米种植。然而玉米虽是高产作物，但往往种植户还是很难将其培育至一个产量高峰。要实现玉米的提质增产，除了选用优良品种、适时播种和加强田间管理外，还有一个非常关键的要素，就是加强玉米中后期的病虫害防治及营养补充，以减少空秆和秃穗。

　　眼下正值东三省玉米的花穗期，也是玉米生长的关键时期。由于今年东北地区前期低温，雨水频繁，导致玉米内涝，使得玉米整个生育周期被迫延后。另外天气潮湿，红蜘蛛、蚜虫等病虫害也时常发生，如果防病增产不及时玉米将面临严重减产甚至绝收。
 
　　“几乎带来 5 倍的回报”
 
　　7 月 22 日，在辽宁昌图县后窑镇船房村，昌图慧飞科技植保队在当地设立对照示范田，给 50 多亩玉米地进行增产和杀菌作业。1 架大疆 T20P 不到半小时就完成了全田的作业。

　　慧飞科技植保队负责人段总表示，他从 19 年开始打玉米增产套餐，“如果进行后期管理，基本上每亩地能增产 150 斤，一晌地至少能增产 2000 斤，按昌图目前玉米收购价格 1.45元/斤计算，就是 2900 元，投入成本才 500-600 元（一晌地），几乎能带来 5 倍的回报。”
 
　　作业地背景

 

　　作业参数

　　用药信息

　　用药解读：配药方面这次选择针对性的药剂，例如杀菌剂能消除浸泡后的玉米大斑病；高磷高钾水肥促进叶片吸收营养，使得作物缓苗生长；杀虫剂能有效控制病虫害发生。
 
　　防治效果
 
　　作业 15 天后，示范田已出现明显分化。“这是打药和没打药的区别，秋收的时候就能见分晓。旁边泛黄的玉米地没有打防病增产，水肥营养流失严重，有可能导致玉米无法完熟。长势较绿的这一片则能领先成熟。”段总解释到。由于 9 月末辽宁就开始下霜，如果玉米不能及时完熟，重量无法起来，收成势必会遭受影响。
 
作业15天后
 
　　“打跟不打真的不一样，这钱不白花。”种植户马哥通过这次对比实验，对大疆农业无人机的作业效果十分满意。
 
　　无法下地？
 
　　“空中”管理新利器
 
　　由于玉米后期已封垄，且今年雨水频繁，传统拖拉机和高架车无法进入玉米地中，否则会造成压苗、陷车等问题，而使用无人机作业则不受地形限制。
 
　　“无人机作业只需一名人工就能搞定，而传统人工作业，则要三至四名人工才能完成，无人机减少成本的同时，效率和质量量还能提升 30%。”
 
　　玉米防病增产
 
　　飞防新蓝海
 
　　作为我国玉米的最大产区，东北地区玉米产量几乎占到全国总产量的三成以上。近年来，东北玉米飞防市场迅速发展，尤其是以防病增产为代表的领域，成为当下一个新的蓝海市场。
 
　　“在东北去年才开始大面积打，之前由于玉米收入价格低，很多农户没有后期投入的意识，认为玉米外表看起来都差不多，但秋收上一称重就看出差别，长势好的玉米棒子大、颗粒饱满、不秃尖。”段总说到。
 
　　谈及未来，飞手李姐表示非常看好玉米飞防市场。因为现在玉米价格非常高，农户也比较注重防病增产。而且玉米感染大斑病、小斑病、灰斑病的几率大，越来越多的农户有了提前预防的习惯和意识，用无人机进行防病增产的市场空间也将越来越广阔。
 
　　旱田示范基地合作招募
 
　　即日起，大疆农业计划与种植户合作共建果园示范基地，通过应用大疆农业解决方案，共同见证和展示智慧农业的发展成果，诚挚邀请您报名参加！
