研究应用飞机大规模喷施抗旱型增糖增产剂的实际效果,为在生产上提高甘蔗的抗旱性,实现增产增糖提供依据。本研究在2008/2009和2009/2010两个年度于广西蔗区甘蔗生长后期应用飞机大面积喷施抗旱型甘蔗增糖增产剂共2 400 hm2,以后分别调查其对甘蔗品质及产量构成因素的影响。结果表明:喷施抗旱型甘蔗增糖增产剂后甘蔗绿叶数和叶绿素都有所增加,并提高了蔗汁锤度和重力纯度、甘蔗纤维分和蔗糖分,降低了蔗汁还原糖分,其中以2009～2010年度喷施50 d时表现最为明显,新植和宿根蔗平均甘蔗蔗糖分比对照提高2.23%(绝对值,下同),新植蔗增糖效果优于宿根蔗;不同时期总平均甘蔗蔗糖分比对照提高1.33%。甘蔗株高、茎径、单茎重有一定的提高,平均甘蔗产量比对照增加14.3%,以宿根蔗增产效果优于新植蔗。应用抗旱型甘蔗增糖增产剂可以防止甘蔗叶片早衰,实现增糖增产,节本增效。
This paper studies the practical application of large-scale spraying of drought-resistant sugar-increasing and yield-increasing agent on aircraft, and provides the basis for improving the drought resistance of sugar cane and increasing sugar yield in production. In the two years of 2008/2009 and 2009/2010, sugarcane sugarcane production of 2,400 hm2 was sprayed on a large area in the late sugarcane growing stage of Guangxi sugarcane planting area. Afterwards, the effects on the quality and yield components of sugarcane influences. The results showed that the green leaf number and chlorophyll of sugarcane increased after sprayed drought-resistant sugarcane increased production of sugar cane, and the brix and gravitation purity of sugarcane juice, the fiber fraction and sucrose content of sugarcane increased, and the reducing sugar content of sugarcane juice decreased The results showed that the average sugar content of sugarcane in newly planted and ratooned sugarcane increased by 2.23% (absolute value, the same below) compared with the control, and that of sugarcane of new plant sugarcane was better than that of sugarcane housed sugarcane at 50 d of spraying in 2009-2010. Sugarcane sugar increased by 1.33% compared with the control. Sugarcane plant height, stem diameter, single stem weight increased to a certain extent, the average output of sugarcane increased by 14.3% compared with the control. The application of drought-resistant sugar cane yield increasing agent can prevent premature aging of sugarcane leaves, increase sugar production, the section of synergy.
