江苏省大豆玉米带状复合种植生产现状调研与分析OA

Soybean-maize belt compound planting mode is an effective way to resolve the land use contradiction between grain and oil crops,increase soybean production capacity and ensure the safety of national grain and oil production.Our team investigated the implementation of soybean-maize belt compound planting mode in Jiangsu province in 2022,and ana-lyzed the basic situation of farmers under this planting mode.We conducted a statistical survey on tillage and preparation land methods,planting pattern,fertilizer operation,prevention and control of diseases and insects and weeds,planting in-vestment,and crop yield.Results showed that the key limiting factors affecting the yield and benefit improvement of soy-bean-maize belt compound planting mode in Jiangsu Province were unsuitable planting methods,drought,high investment and cost,high temperature stress,high fertilizer prices,low seedling quality,mismatch of agricultural machinery and techniques,unreasonable variety selection,maize borer damage,etc.On this basis,the development strategy of soybean-maize belt compound planting in Jiangsu Province was put forward:on the premise of selecting density-tolerant,wide-a-dapted and multi-resistant varieties,focusing on key cultivation techniques,supporting the integration of reasonable close planting,timely sowing,green prevention and control,simplified fertilization,chemical control and lodging resistance,timely harvest and other techniques to form a green high-yield,high-efficiency and light,and simple cultivation technology system,characterized with saving labor and cost,increasing production and increase efficiency,increasing farmers' in-come,and serving the compatible development of soybean and maize.
