【摘要】 以无核黄皮为试材,研究了不同形态氮肥作为壮梢肥和促花壮果肥,对其秋梢生长、果实产量及品质的影响。结果表明:4种氮肥处理中施用酰胺态氮+铵态氮(尿素和硫铵各占氮源50%)的处理在满足秋梢生长中表现最优;无核黄皮结果果实产量均以施氮品种为酰胺态氮+铵态氮处理为最高;果实的可溶性固形物、可溶性糖含量、酸度在4个不同氮源的氮肥处理之间均没有显著性差异;但是无论在海日园还是波波园中酰胺态氮+铵态氮配施处理维生素C含量最高。在施用氮含量相同下,酰胺态氮与铵态氮配合制成的无核黄皮专用肥能够促进其秋梢生长发育,提高果实产量和改善品质。更多还原

【Abstract】 Take Glausena lansium as meterials,a field experiment was carried out to investigate the effects of four different forms of nitrogen fertilizer as the effects of strong little fertilizer and strong fruit fertilizer on the growth of the autumn shoot and the yield and quality of the fruit in Clausena lansium.The results showed that the growth of the autumn shoot was optimal when the amide nitrogen+ammonium nitrogen(urea and ammonium sulfate,50% of each nitrogen source) was applied in four nitrogen fertilizer.The yield of the fruit in amide nitrogen+ammonium nitrogen treatment was the highest in four nitrogen fertilizer treatments.The soluble solids,the soluble sugar content,the acidity in Fruit were not a significant difference among the four different nitrogen sources treatments.Regardless of in the Hai-Ri Park or Bo-Bo park,Vitamin C content in amide nitrogen +ammonium nitrogen treatment was the highest among the four different nitrogen sources treatments.When the application of nitrogen content was the same,the special fertilizer of nitrogen for Clausena lansium was made by the amide nitrogen and ammonium nitrogen,which to improve the growth and development of autumn shoot,and to improve the fruit yield and quality.更多还原
