摘要
本研究在常规化肥量减半条件下,研究黄腐酸钾(FA-K)和内生菌剂(单/复合)对云蔗08-1609甘蔗生长的影响,以期为糖蔗产业研制高效有机复合菌肥提供参考依据。通过浸种催芽试验和盆栽试验,探究内生菌剂对甘蔗种苗生长的作用,不同施肥配方处理[常规施化肥(F_(1))、50%常规施化肥量+黄腐酸钾(F_(2))]和内生菌剂处理对甘蔗苗期生长的促生效应及其交互作用。结果表明:B9+YC89复合菌剂可以显著促进甘蔗种苗生长,采用F_(2)施肥配方和施内生菌剂可以显著提高甘蔗苗期农艺性状、光合及生理指标,F_(2)较F_(1)处理能显著提高蔗苗的茎粗、鲜干质量、+1叶面积、根系活力、光合参数、可溶性蛋白含量、可溶性糖含量、谷氨酰胺合成酶(glutamine synthetase,GS)活性、谷氨酸合成酶(glutamate synthase,GOGAT)活性;F_(2) B9+YC89处理促进+1叶长、+1叶面积、主茎叶片数、干质量、根系活力、光合作用、可溶性物质含量及GS、GOGAT活性效果最为显著。因此,在甘蔗生产中,采用B9+YC89复合菌剂浸种催芽可促进甘蔗种苗萌发;在50%常规施化肥条件下,黄腐酸钾较常规施化肥处理进一步促进云蔗08-1609甘蔗苗期生长,黄腐酸钾与B9+YC89复合菌剂配合施用能有效促进云蔗08-1609甘蔗苗期生长。本研究结果有利于推动甘蔗产业减肥增效方向的发展,为新型栽培种植技术提供思路。
The study was aimed to study the effects of potassium fulvic acid(FA-K)and endophytic agents(sin-gle/combined)on the growth of sugarcane of Yuncane 08-1609 under the condition of halving the amount of conven-tional chemical fertilizers and to provide a reference for the subsequent research on high-efficiency organic compound bacterial fertilizer for increasing yield and weight loss in the sugar cane industry.The effects of endophytic agents on the growth of sugarcane seedlings and the growth-promoting effects of different fertilization formula treatment[con-ventional fertilizer application rate(F_(1)),50%conventional fertilizer application rate+potassium fulvic acid(F_(2))]and endophytic agent treatment on the growth of sugarcane seedlings and the interaction were investigated through soaking seed germination test and pot experiment.The“B9+YC89”compound agent could significantly promote the growth of sugarcane seedlings,compared with F_(1),F_(2) fertilization formula and endophytic agent could significantly improve agro-nomic traits,photosynthetic and physiological indexes of sugarcane seedlings,and F_(2) treatment could significantly in-crease stem diameter,fresh dry weight,+1 leaf area,root activity,photosynthetic index,soluble protein and soluble sugar content,and glutamine synthetase and glutamate synthase(GS and GOGAT)activities of sugarcane plants.F_(2)“B9+YC89”treatment had the most significant effects on+1 leaf length,+1 leaf area,number of main stem leaves,dry weight,root activity,photosynthesis,soluble matter content and two enzyme activities.In summary,in sugarcane pro-duction,the use of“B9+YC89”compound microbial agent soaking and germination can promote the germination of sugarcane seedlings.Under the condition of 50%conventional chemical fertilizer,potassium fulvic acid further pro-moted the seedling growth of Yuncane 08-1609 compared with conventional chemical fertilizer treatment,and the com-bined application of potassium fulvic acid and“B9+YC89”compound microbial agent could effectively promote the seedling growth of Yuncane 08-1609.The study are conducive to promoting the development of weight loss and effi-ciency increase in sugarcane industry,and provide ideas for new cultivation and planting technologies.
