适合甘蔗间种玉米品种筛选试验

以生产上大面积推广的4个普通玉米品种、2个鲜食玉米品种在甘蔗行间种植,调查分析玉米甘蔗农艺性状和经济效益。结果表明,玉米品种不同、生育期的长短与植株性状差异,对甘蔗株高、有效茎数的形成、甘蔗产量及全年收益有一定的影响。鲜食糯玉米品种玉美头601、桂糯519和普通玉米品种浚单20植株矮、生育期短,间种甘蔗植株高,有效茎数在81778-84325条/hm2,甘蔗产量在112.6-116.1t/hm2,与单种甘蔗的有效茎数及产量差异不显著,与间种其它玉米品种甘蔗有效茎数、产量差异达极显著水平,比单种甘蔗效益高443.8-11393.8元/hm2,适合用于甘蔗间套种。

Screening experiment of sugarcane and corn varieties suitable to interplanting pattern

4 common maize varieties and 2 fresh-eating maize varieties in large-scale production are interplanting with sugarcane to investigate and analyze maize and sugarcane＇s agronomic characters and economic benefit. The results show that, the different maize varieties, the length of growth period and differences in plant features have certain impact on sugarcane plant height, the formation of effective stalk number, sugarcane yield and annual profit. Waxy maize varieties as Yumeitou 601, Guinuo 519 and common maize varieties as Xundan 20 have short plant height, short growth period, and higher in- terplanting-sugarcane plant height, effective stalk number in the 81778-84325/hm^2, yield of sugarcane of l l2.6-116.1t/hmz, comparing with sugarcane single-planting, the effective stalk number and yield differences is not significant.comparing with experiment intercropping with other maize varieties, their sugarcane stalk number, the yield difference are reaching extra-significant, the yield difference was significant, Their benefit comparing with single sugarcane planting is 443.8-11393.8 Yuan/hm^2 higher, suitable for sugarcane intercropping.
