摘要
在柑橘上进行了不同有机无机肥配施试验,研究不同有机氮和无机氮配比对柑橘产量、品质及养分吸收的影响。结果表明:有机无机肥配施处理提高了柑橘大果的比例,降低了小果的比例,并提高了柑橘的Vc、总糖、可溶性固形物含量,促进了植株对钾素的吸收,从而改善了果实品质。其中40%有机氮替代40%无机氮处理,柑橘产量增加4000.5kg/hm2,增幅8.3%,是提高柑橘综合品质的最佳施肥处理。
Effects of different organic nitrogen and inorganic nitrogen ratio on citrus yield, quality and nutrient ab- soqotion were studied on citrus with different organic and inorganic fertilizers. The resuhs showed that the applica- tion of organic and inorganic fertilizer can improve the proportion of big fruit, reduce the proportion of small fruit, in- crease the content of Vc, total sugar and soluble solids in citrus, promote the absorption of plant to potassium, and im- prove the fruit quality directly. After 40% organic nitrogen substituted for 40% inorganic nitrogen, the yield of citrus could be increased by 4000.bkg/hm2, the increase was 8.3%, and 40% organic nitrogen substituted 40% inorganic ni- trogen treatment for improving the comprehensive quality of citrus.
