I. INTRODUCTION Citrus size annual results are problems in production for many years. The main reason for the formation of annual results of size and size and the technology of overcoming the annual results of size and size have made a great deal of achievements reported by fruit tree workers at home and abroad. Sichuan citrus orchards, mostly in hilly areas, soil and water erosion, soil infertility, extensive management habits of thin planting, low yields and the size of the annual output is more prominent. 1962 - 1965 We at the Jiangjin experimental site of the size of the annual results of significant adult sweet orange orchard, the comprehensive technical measures and single factor test to study the biological characteristics of plants
