摘要：

为解决化肥用量过多问题,提高甘蔗节本增效,选取云南省6个主要蔗区作为试验点,以B9菌剂、有机肥、复混肥不同组合为供试肥料设置不同施肥处理,探讨各肥料处理对甘蔗生长、产量、糖分等农艺性状的影响,并分析甘蔗种植效益。结果表明,施用B9菌剂组合的肥料不同程度促进甘蔗出苗;6个试验点中除盈江县和景谷县施用B9菌剂组合的肥料对促进甘蔗分蘖作用不明显外,其他4个试验点均达到有效促进;与普通复混肥处理相比,施用B9菌剂的处理在株高、茎径、有效茎数、蔗茎产量、蔗糖分等性状有一定程度的增加,但影响不显著。选取元江县进行经济效益分析,结果表明,施用B9菌剂组合的肥料比对照收益高,而没有B9菌剂组合的肥料比对照低。综上所述,施用“B9菌剂+有机肥+化肥”组合的肥料在稳产减肥（化肥）方面起到了积极的作用,值得应用推广。

Abstract:

To solve the problem of excessive fertilizer application, improve sugarcane cost-saving synergies, this study used different fertilizer treatments with B9 bacteria agent to influence the agronomic traits and economic benefits of sugarcane, so as to provide a basis for the application of B9 bacteria agent in sugarcane production. Six major sugarcane areas were selected as test sites in Yunnan Province. Different fertilization treatments were carried out with different combinations of B9, organic fertilizer and compound fertilizer to study the agronomic traits of sugarcane growth, yield and sugar content. And the planting benefits of sugarcane were analyzed. The results showed that B9 bacteria combined fertilizer could promote the emergence of seedlings in different degrees. In the six experimental sites, except Yingjiang and Jinggu where the application of B9 bacteria combined fertilizer had no obvious effect on promoting tillering of sugarcane, the other 4 test points all achieved effective promotion results. Compared with the conventional compound fertilizer treatment, the application of B9 bacteria improved the traits like plant height, stem diameter, effective stem number, sugarcane stem yield, sucrose content and so on, but the effects were not significant. The economic benefit analysis of Yuanjiang showed that the benefit of B9 combined fertilizer treatment was higher than that of the control, but the benefit of the fertilizer treatment without B9 bacteria was lower than that of the control. In summary, applying the combination of ‘B9 bacteria agent + organic fertilizer + chemical fertilizer’ plays a positive role in stabilizing yield and reducing fertilizer amount, and has a value of application and promotion.
