The aim of the present study was to determine the pre-emergence application of 30%mixed butachlor and oxyfluorfen EW at a.i. 360~900 g/hm2 on controlling weeds in sugarcane fields. The results showed good control effect on annual weeds in Gramineae and broad-leaved weeds after 30 and 60 days of spraying. The control efficacy of 30%mixed butachlor and oxyfluorfen EW at dosages of a.i. 450~540 g/hm2 were more than 86%. It was safe to sugarcane at such dosages.

蔗渣是甘蔗制糖副产物,其热量达1900千卡/千克,可用作造纸原料和锅炉生物质燃料.从氮氧化物的生成机理、烟气脱硝技术,结合广西糖厂的实际,对蔗渣烟气脱硝可行性和技术方案进行了探讨,提出了推进糖厂烟气氮氧化物治理,实现达标排放及氮减排的建议.

介绍明阳糖厂制糖废水生化处理和节水工程技改以及应用效果。经综合治理后,榨季COD排放总量由原来的686.9吨降低到20.5吨,降幅97%,外排废水COD平均值为22mg/L,远低于国家规定的排放标准(100mg/L),水重复利用率达99.98%,生产过程实现零取水。

Global Positioning System(GPS) is generally applied in various fields such as agriculture,forestry,traffic,electric power,petroleum,survey and so on.Its application in sugar industry is a momentous technology revolution,which has a bright prospect in application and development.GPS combined with sugar farm management information system can effectively arrange sugarcane reaping and transport,preserve fresh sugarcanes,reduce sugar loss,increase business benefits and supervise vehicles.Cross-area transportation of sugarcanes can be efficaciously precluded,harvest of sugarcanes will be in order,the output of sugarcanes can be accurately calculated.
