减施化肥条件下复合内生菌剂与黄腐酸钾配施对甘蔗生长的影响
Effect of Combined Application of Compound Endophytic Agent and Potassium Fulvic Acid on Sugarcane Growth under Reduced Chemi-cal Fertilizer Application
摘要
Abstract
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(F1),50%conventional fertilizer application rate+potassium fulvic acid(F2)]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 F1,F2 fertilization formula and endophytic agent could significantly improve agro-nomic traits,photosynthetic and physiological indexes of sugarcane seedlings,and F2 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.F2"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.关键词
