【摘要】 为了进一步提升南宁市武鸣区沃柑的品质与效益，探究有机肥料结合化肥施用对调节沃柑树体营养变化和改善沃柑春梢生长期农艺性状的作用，在南宁市武鸣区沃柑幼树园中进行肥效对比试验。结果表明，施用8%生物发酵饼肥4 500 kg/hm~2+45%硫基复合肥（15-15-15）750 kg/hm~2后，沃柑叶片转绿快、叶色浓绿。施用8%生物发酵饼肥4 500 kg/hm~2+45%硫基复合肥（15-15-15）750 kg/hm~2对沃柑树势、春梢的前期伸长生长有一定促进作用，能增加挂果数量。生物发酵饼肥能明显提高沃柑幼树树势，调节沃柑树体营养变化。更多还原

【Abstract】 In order to further improve the quality and benefit of mandarin orange in Wuming District of NanningCity, and explore the application effects of organic fertilizer combined with fertilizer on regulating the nutritionalchanges of mandarin orange trees and improving the agronomic characteristics of mandarin orange in the spring shootgrowth stage, a comparative experiment on fertilizer efficiency was carried out in the young mandarin orange orchardin Wuming District, Nanning City. The results showed that after applying 8% biological fermentation cake fertilizer4 500 kg/hm~2 +45% sulfur-based compound fertilizer(15-15-15) 750 kg/hm~2, the leaves turned green quickly and theleaves were dark green. Application of 8% biological fermentation cake fertilizer 4 500 kg/hm~2+45% sulfur basecompound fertilizer(15-15-15) 750 kg/hm~2had a certain effect on the growth of tree potential and early elongation ofspring shoot, and could increase the number of fruits. Biological fermentation cake fertilizer can obviously improve thegrowth of young trees of mandarin orange and regulate the nutritional changes of mandarin orange trees.更多还原
