潮土区蜜柚配方施肥研究

Study on Prescription fertilization of Honey Pomelo in the Moisture Soil Area

[目的]研究配方施肥对潮土区蜜柚产量和品质的影响。[方法]采用均匀试验设计方法,在蜜柚上进行有机肥、氮肥、钾肥3因素5水平的配方施肥试验。[结果]与传统施肥习惯相比,配方施肥处理能明显提高果实的产量及改善果实的品质,而有机-无机配施的处理在提高蜜柚果实产量和改善果实品质方面的效果优于单施化肥的处理。综合产量和品质2个因素,株施有机肥料80.0 kg、化学肥料N 1.0 kg、P2O50.5 kg、K2O 1.4 kg(2号处理)的施肥配方显著提高蜜柚的产量和品质,株产达到109.87 kg。[结论]科学合理的配方施肥可提高蜜柚的产量和品质。

[Objective] The aim was to study the effect of prescription fertilization on the yield and quality of honey pomelo in the moisture soil areas.[Method]Uniform experimental design was adopted to carry out honey pomelo prescription fertilization experiment from 3 factors 5 levels,namely organic fertilizer,nitrogen fertilizer and potassium fertilizer.[Result] Comparing with the conventional fertilization,prescription fertilization could improve the yield and quality of pomelo fruits,and the combined application of organic and inorganic fertilizer treatments was superior to the application of pure fertilizer in increasing the yield of pomelo fruits and improving the quality of pomelo fruits.Comprehensively considering factors of yield and quality,prescription fertilization increased the yield and quality of honey pomelo significantly,namely,organic fertilizer 80.0 kg,chemical fertilizer of N 1.0 kg,P2O5 0.5 kg,K2O 1.4 kg per plant（No.2 treatment） and the yield per plant reached 109.87 kg.[Conclusion] Scientific and rational prescription fertilization could improve the yield and quality of honey pomelo.
