平衡施肥改善南丰蜜桔品质效应研究

Study on Improving Fruit Quality of Nanfeng Orange by Balanced Fertilization

2000～2002年进行了平衡施肥改善南丰蜜桔品质的试验研究,结果表明:适量增施钾肥和合理修剪能显著提高南丰蜜桔的产量及其食用品质,降低疮痂病的发病率和病情指数;施用硫磺有一定的增产作用,但会降低果实的品质。增施钙、镁肥对产量影响不大,但可以提高果实的品质。平衡施肥能显著提高南丰蜜桔的品质和经济效益。

Experiments in improving the fruit quality of Nanfeng orange by balanced fertilization were conducted during 2000~2002, the results indicated that proper increase in application rate of potassium and rational pruning could enhance the yield, improve fruit quality of Nanfeng orange, and decrease the incidence and disease index of scab. Application of sulphur had some effects on increasing yield, but it could decrease the fruit quality. Applying calcium and magnesium fertilizer could improve fruit quality without influence on yield. So balanced fertilization can improve the fruit quality and increase the economic benefits.
