| Abstract: | A series of experiments were conducted for several years to study mineral nutrition and fertilization tech-nique of sweet orange. It revealed the relationship between nutrient properties and equilibrium fertilization,and disscussed the changing law of plant nutrition during one year. The results showed that the important pe-riods of nutrition were the period of spring shoots turning green and the period of nutrients storage in autumnand winter. On alkaling purple soils, the chlorosis of orange trees which were on Poncirus trifoliata and Cit-rus reticulata cv. Hongju rootstocks were brought about by Fe,Mn,B and Mn,Zn,Fe deficiency respectively.The optimum ratio of N,K application for mature trees was l : 0.75,with N 400g and K2O 300g per tree inone year. Phosphate application showed little effect on purple soil. |
