不同肥料处理对甘蔗产量和蔗糖分的影响

Effects of Different Fertilizer Treatments on Yield and Sucrose Content of Sugarcane

探讨不同肥料处理对甘蔗产量和蔗糖分的影响,为广西来宾市甘蔗产业的提质增效提供科学依据。以福农41号为试验材料,不施肥为对照,研究施用垂青■液态复合肥、蔗得金■药肥混剂(常规施肥)及不同施用量,对甘蔗农艺性状、产量、蔗糖分和经济效益的影响。结果表明:施用垂青■液态复合肥1875 kg/hm2时,甘蔗出苗率、分蘖率、株高、茎径、产量和蔗糖分,以及经济效益均最高;与常规施肥相比,甘蔗产量增加了7770 kg/hm^2、蔗糖分提高了0.5%(绝对值)、经济效益增收了3885元/hm2,甘蔗增产增糖效果和经济效益均最佳,值得在来宾市蔗区推广应用。

The effects of different fertilizer treatments on yield and sucrose content of sugarcane were investigated,in order to provide scientific basis for improving sugarcane yield,quality and economic benefit in Laibin city.With Funong 41 as material and no fertilization as control,the field experiment was conducted by applying Chuiqing®liquid special fertilizer and Zhedejin®pesticide-fertilizer(conventional fertilization)and its quantity.The agronomic character,yield,sucrose content and economic benefit of each treatment were investigated and analyzed.The results showed that seedling emergence rate,tillering rate,plant height,stalk diameter,yield,and economic benefit were the highest among 5 treatments under the application 1875 kg/hm2 of Chuiqing®liquid special fertilizer.Compared with the treatment of conventional fertilization,the yield,sucrose content and economic benefit could increase 7770 kg/hm2,0.5%(absolute value),3885 Yuan/hm2,respectively.Furthermore,the application 1875 kg/hm2 of Chuiqing®liquid special fertilizer is the best to worth being promoted and applied in sugarcane planting area in Laibin.
