开展了甘蔗间作不同大豆品种、间作期、施肥及间作效益等研究,探索总结了甘蔗间作大豆科学的栽培技术,为大田生产应用提供依据。实验结果表明,甘蔗间作大豆会促使甘蔗的植株变高,蔗茎变粗,单茎变重,有效茎数减少,进而对甘蔗产量产生影响。其中,桂春豆103、桂春豆104和桂春豆1号与甘蔗间作后甘蔗不减产,对甘蔗的影响小,比较适合与甘蔗间作;间作大豆的适宜播种期以3月上旬甘蔗植后15天为宜;间作大豆施肥量以施三元复合肥225.0 kg/hm2为宜。
Cane intercropping for different varieties of soybean, intercropping, fertilization and intercropping benefits, etc., to explore and summarize the intercropping of soybean science and cultivation techniques for the field production and application provide the basis. The results showed that the intercropping of sugarcane with soybean would promote the plant height of sugarcane to be larger, the diameter of sugarcane to be thicker, the weight of single stem to be heavier and the number of effective stem to decrease, and then affect the yield of sugarcane. Among them, Gui-jun bean 103, Gu-jun-bean 104 and Guichong-1 and sugar-cane intercropping of sugarcane did not reduce production, the impact of sugarcane is small, more suitable for intercropping with sugar cane; Intercropped soybean suitable sowing period in early March sugarcane planting 15 days is appropriate; intercropping soybean fertilizer to Shi San Yuan 225.0 kg / hm2 compound fertilizer is appropriate.
