为探索木薯酒精厌氧发酵液作为部分灌溉用水及肥源替代化肥在香蕉生产的应用效果,以常规施肥作为对照,研究木薯酒精厌氧发酵液(COD值为1 100~1 300 mg/L)不同施用量对香蕉生长发育及蕉园土壤肥力的影响。结果表明,施用木薯酒精厌氧发酵液能促进香蕉生长发育,显著提高产量和果实品质,改善土壤肥力,最佳淋施量为750 t/hm2,较常规施肥,产量增加了19.80%,果实Vc含量、可溶性总糖和可溶性固形物含量分别提高了28.19%、5.22%和8.98%,土壤碱解氮、有效磷、速效钾和交换性钙含量分别提高了12.76%、267.40%、53.51%和2.10%。表明木薯酒精厌氧发酵液可作为优良的液体肥料和土壤改良剂应用于香蕉生产。
In order to explore the application effect of cassava alcohol anaerobic fermentation broth as part of irrigation water and alternative fertilizers in banana production, conventional cassava fertilizer was used as a control to study the cassava alcohol anaerobic fermentation broth (COD value 1-100-1 300 mg / L) Effects of Different Application Rate on Growth and Development of Bananas and Soil Fertility of. The results showed that the application of cassava alcohol anaerobic fermentation broth can promote the growth and development of banana, significantly improve the yield and fruit quality, improve soil fertility, the optimum amount of irrigation is 750 t / hm2, compared with conventional fertilization, the yield increased by 19.80% The contents of soluble sugar, total soluble sugar and soluble solids increased by 28.19%, 5.22% and 8.98%, and the contents of soil available nitrogen, available phosphorus, available potassium and exchangeable calcium increased by 12.76%, 267.40%, 53.51% and 2.10% %. Cassava alcohol anaerobic fermentation broth can be used as an excellent liquid fertilizer and soil conditioner for banana production.
