黑龙江省三江平原地区玉米大豆带状复合种植技术要点

Key Points of Maize and Soybean Strip Compound Planting Technology in Sanjiang Plain of Heilongjiang Province

随着黑龙江省大豆、玉米种植结构调整,大豆与玉米种植争地的矛盾日益加剧。传统玉米大豆间套作通过集约利用土地和可持续发展得到了一定发展,但由于施肥技术不协同、病虫草防治技术缺乏、田间结构分布不合理、倒伏严重等瓶颈问题,难以高产稳产,不能融入现代农业。通过传承传统玉米大豆间套作生态可持续、集约利用资源的方式,创新解决低位大豆倒伏、光肥资源协同利用、间套作综合防控的玉米大豆带状复合种植技术应运而生。

With the adjustment of soybean and corn planting structure in Heilongjiang province,the contradiction between soybean and corn planting land is increasingly aggravated. Traditional maize and soybean intercropping had made progress through intensive land use and sustainable development,but it was difficult to produce high and stable yield,and couldn’t be integrated into modern agriculture because of the bottleneck problems such as uncoordinated fertilization technology,lack of disease and insect pest control technology,unreasonable field structure distribution and serious lodging. By inheriting the traditional corn and soybean intercropping with ecological sustainability and intensive resource utilization,the zonal corn and soybean composite planting technology,which innovatively solved low soybean lodging,collaborative utilization of light and fertilizer resources,and comprehensive prevention and control of intercropping came into being.
