甘蔗宽窄行间作花生对甘蔗产量、品质及经济效益的影响

Effects of Sugarcane Intercropping Peanut under Wide-Narrow Row Spacing on the Yield,Quality and Economic Benefit of Sugarcane

甘蔗是我国的主要糖料作物,但近年来种植效益普遍较低。为提高土地利用率和实现机械化操作,增加蔗地综合经济效益,进行甘蔗宽窄行(宽行行距1.8m,窄行行距0.6m)间作花生试验,探索宽窄行间作对甘蔗产量、品质及经济效益的影响。结果表明,与甘蔗宽窄行单作和常规等行距单作相比,宽窄行间作花生种植模式的甘蔗出苗率、分蘖率、有效茎数和产量有所下降,茎径有所提高,株高和蔗糖分差异不显著,因多收1造花生,每667m^(2)纯收益分别增加403元和345元,为甘蔗产业的可持续发展提供了理论依据。

Sugarcane is the main sugar crop in China,but the planting benefit is generally low in recent years.In order to improve the land utilization rate,realize mechanized operation and increase the comprehensive economic benefit of sugarcane land,the experiment of sugarcane intercropping peanut under wide-narrow row spacing(wide row spacing 1.8 m and narrow row spacing 0.6 m)was carried out to explore the effects of intercropping under wide-narrow row spacing on the yield,quality and economic benefit of sugarcane.The results showed that compared with sugarcane monocropping under wide-narrow row spacing and regular equal spacing,the seedling emergence rate,tillering rate,millable stalks and yield of sugarcane under wide-narrow row spacing decreased somewhat,while the stalk diameter increased somewhat.There was no significant difference in plant height and sucrose content.The net income per 667 m^(2) increased by 403 yuan and 345 yuan respectively,due to getting an extra crop of peanuts.It provided a theoretical basis for the sustainable development of sugarcane industry.
