摘要
对龙门县4个村4～6年生年橘进行不同配方的施肥试验。结果表明,氮、磷、钾最优配方比为1∶0.3∶0.8,全年总施肥量(尿素、过磷酸钙、硫酸钾)为5 096 kg/hm2,并增施15 kg/hm2的硫酸镁,生产出的年橘质量好,产量高,可获取较高的经济效益。
Different formula fertilization experiments were made to 4～6-year-old Nianju trees in four villages of Longmen County.The results showed that when the optimal ratio of N,P and K was 1∶0.3∶0.8,the total fertilizer rate for a whole year was 5 096 kg/hm^2（urea,calcium superphosphate,potassium sulfate） and the fertilizer rate of magnesium sulfate was 15 kg/hm^2,the Nianju had good quality and high yield,and can obtain high economic benefit.
