摘要
甘蔗间套种玉米有隔行间种、行行间种等2种方法,不同方法对甘蔗产量影响不同;新植蔗和宿根蔗不同的种植密度对甘蔗产量有不同的影响,新植蔗每667 m^2间种玉米1 127株以下、宿根蔗每667 m^2间种1 262株以下比较合适;玉米间套种时间过早造成甘蔗产量减产,一般在新植蔗幼苗长到2叶1心、宿根蔗出苗达30%时播种玉米,不影响甘蔗的生长;生育期短、株高较矮、株型紧凑、叶片较窄的玉米品种,对甘蔗产量的影响较小;甘蔗套种玉米对甘蔗病虫害有一定的控制作用。
There are two methods that plant corn in sugarcane, one is plant a line, the other is plant interline. The two methods have different influence on sugarcane yield. It was adopt for planting less than 1 127 per 667 m2 for new planting, less than 1 262 per 667 m2 for the old planting which the sugarcane roots leaved soil. Different density between them had different influence on sugarcane yield. When we planted corn in two and a half leaves of new planting sugarcane and 30% of old planting, they didn＇t influence the sugarcane growing. The yield of sugarcane was decreasing when we planted corn early. It was a little influence on sugarcane yield when we chose the variety of shorter in life, lower in plant height, narrower and straighter in leaves. Intercroping could controll the sugarcane pest and disease.
