Abstract

Abstract: To regulate the soil acidity and silicon, calcium and magnesium nutrient content in banana orchards, and improve banana yield and quality, field experiments were conducted to investigate the effects of different varieties of silicon-calcium-potassium-magnesium (SCPM) fertilizers on banana yield, quality and soil nutrients. Compared with conventional fertilization, the results showed that the annual production of banana increased significantly by 3.82%-5.64% under the application of 750 kg/hm2 of SCPM fertilizers, but there was no significant difference of yield between different treatments (P＞0.05). The length of banana finger could be significantly increased by SCPM. The results of quality analysis indicated that the application of SCPM were effective to improve the content of vitamin C, soluble sugar and soluble solids in fruit pulp. The use of SCPM could increase soil pH value by 0.12- 0.72 units, and raise the available level of calcium and magnesium in the soil. Comprehensively compared, the gray-powder SCPM fertilizer has the best effect in banana cultivation.
