For orange trees
1/ Pay attention to the organic fertilization, develop the orchard green manure.
2/ Fertilize the Silicon-calcium fertilizer, lime for the acid soil 
3/ Optimize the  dosage of N, P, K fertilizer, Fertilizer proportion and time of fertilizing, supplying the micronutrient such as Ca, Mg, S, B, Zn and so on.
4/ Using the hole application or Furrow application instead of broadcasting. 
5/ Combine the fertilization and the water management as well as High yield and high quality cultivation technology, use fertigation during the arid season.
Methods of fertilizing
1/ Yield is 3000kgs/667㎡ or above: Organic fertilizer 2-4 cube/667㎡, N fertilizer(N)25-35kgs/667㎡, P fertilizer(P2O5)8-12kgs/667㎡, K fertilizer(K2O)20-30kgs/667㎡.

The orchard which lacks of Ca, Mg and S, calcium magnesium phosphate fertilizer is adopted; The orchard which is lack of Zn and B, we can fertilize 0.5-0.75kgs sodium borate, 1-1.5kgs fertilizer grade zinc sulfate powder or zinc sulfate granular, mixed with the organic fertilizer in autumn; Orchard whose pH<5.50, use 60-80kgs/ 667㎡ or dolomite fines, 50% of which used in autumn, the other used in summer.
