The banana team of the Tropical Fruit Research Center of the Institute of Thermal Sciences of the Chinese Academy of Thermal Sciences has made new progress in the study of banana nitrogen fertilizer reduction and application of organic fertilizer, revealing the effects
of nitrogen fertilizer reduction and application of organic fertilizer on the accumulation of substances, physiological resistance and nitrogen fertilizer destination at the seedling stage of bananas.
of nitrogen fertilizer reduction and application of organic fertilizer on the accumulation of substances, physiological resistance and nitrogen fertilizer destination at the seedling stage of bananas.
The reduction of chemical fertilizers and the application of organic fertilizers are of great significance to the sustainable development of the agricultural industry, but their effects on banana growth, physiology and nitrogen displacement of fertilizers have been rarely studied
.
This study simulated nitrogen leaching, and the results showed that compared with conventional fertilization, all organic nitrogen substitution treatments significantly reduced the amount of nitrogen leaching and apparent loss of fertilizer, and increased nitrogen soil residues.
A 20% reduction in nitrogen fertilizer and 30% substitution of organic nitrogen can significantly promote the accumulation of banana substances, enhance the physiological resistance of bananas, increase the utilization rate and residue of nitrogen fertilizer, and reduce nitrogen pollution
