春玉米免耕套种栽培小区对比试验

Comparison experiment of spring maize no-tillage and intercropping cultivations

套种是一种能充分利用光、热、肥、水等自然资源的种植方式,具有减少病虫害、实现农业高产高效等优点。本试验主要观测不同套种模式对玉米产量的影响。试验结果:①桂单589套种夏大豆、②桂单589套种秋玉米、③正大619套种夏大豆、④正大619套种秋玉米;667m2产干籽分别为452.2、461.2、537.3、526.9kg,处理③正大619套种夏大豆产量最高。

Intercropping is a cultivation method to make full use of light, heat, fertilizer, water and other natural resources, which can reduce pests and diseases, achieve high yield and high efficiency of agriculture. This experiment is mainly conducted to observe effects of different intercropping patterns on corn yield. Experiment results： four treatments ① Guidan589 interplanting with summer soybean ②Guidan589 interplanting with autumn corn ③ Zhengda619 interplanting with autumn summer soybean, ④ Zhengda619 interplanting with autumn corn; dry seed yields are 452.2kg, 461.2 kg, 537.3 kg and 526.9 kg respectively. Treatment ③ Zhengda 619 interplanting with summer soybean has the highest yield.
