摘要
采用调查问卷的方法研究高州市香蕉施肥状况,分析当地香蕉生产中施肥状况及其存在的主要问题,为指导高州市的香蕉施肥、提高香蕉产量、改善香蕉品质提供参考依据。调查分析结果表明,高州地区香蕉平均产量约为2134.6kg/667m^2,当地蕉农施用有机肥的比例约为91.3%,主要以干鸡粪为主,但是有机肥的施用量相对较低,有机肥氮、磷、钾的投入量为O.254、0.226、0.205kg/(株·a),化肥施用比例为100%,其中当地蕉农重施氮肥和磷肥,约2/3的农户钾肥施用量不足,个体之间施肥量及产量均存在较大差异,化肥氮、磷、钾的平均投入量为0.433、0.224、0.508kg/(株·a)。施肥中存在的主要问题是重视化肥施用,有机肥的施用量不足,且肥料养分比例欠合理,建议增施钾肥,将氮、钾比例调整至1:(1.2~1.3),同时注重有机肥与化肥的配合施用,发挥当地有机肥资源优势建立绿色香蕉生产基地。
The fertilization status of banana in Gaozhou of Guangdong province were investigated and analyzed with questionnaire. The main problems in fertilization were discussed, as well supplied a scientific solution and a fertilization suggestion.The investigation results showed that the mean yield of banana was about 2 134.6kg/667m^2 in Gaozhou,about 91.3% of the farmers applied organic fertilizer during planting,dry chicken manure were most, but the organic fertilizer application was too low to harvest more production. Organic nitrogen, Organic-P and Organic potassium applied for every banana tree were 0.254,0.226,0.205kg/a. There were 100% of the farmers applied fertilizer, but nitrogen and phosphorus fertilizer application were much more, about 2/3 banana planters didn't apply enough potash fertilizer. The difference of yield was large among individual farmers according to the difference of fertilizer application. Chemical nitrogen, phosphorus and potassium applied for every banana tree were 0.433,0.224,0.508kg/a. The existing questions were that the chemical fertilizer used for only less organic fertilizers, as well the radios of the nutrition were not reasonable. The suggestion was that increase more potash fertilizer in order to adjust nitrogen and potassium ratio to 1:(1.2-1.3),while pay more attention to match up or- ganic and inorganic chemical fertilizer. Furthermore, build up a production base of green products to depend on the organic fertilizer resource superiority in the locality.
