Technical requirements for the quality of Fuyang rock sugar orange (1) Site conditions. An area between 200 and 350 meters above sea level within the protected area. The soil type is red sand and purple soil. The soil has a particle size of 40% to 50%, pH value of 6 to 7, organic matter content ≥1.5%, soil layer thickness ≥60cm, and groundwater level ≤1m. (2) Cultivation management. 1. Varieties: local varieties and excellent varieties of rock sugar orange. 2. Breeding of seedlings: Collecting scions from robust mother trees without quarantine pests and diseases, grafting and breeding with large-leaf clams or oranges as rootstocks. 3. Cultivation techniques: (1) Colonization: The time is from late February to mid-March, before the spring shoots sprout or before the early October to early November. The cultivation density of flat or gentle slope is ≤630 plants/ha, and the planting density of slope greater than 15 degrees is ≤900 plants/ha. (2) Soil management: implement deep tillage and soil improvement, mature soil; implement intercropping and grass cultivation to improve soil structure. (3) Fertilization: Young trees are mainly nitrogen fertilizer, combined with phosphorus and potassium fertilizers, and fertilized 5 to 8 times a year; the results are based on organic fertilizer, high-quality cake fertilizer, biological fertilizer and microbial fertilizer, and rational use of inorganic fertilizer. Fertilization in soil formula, fertilize 3 to 5 times a year, and apply more than 15 tons of organic fertilizer per hectare per year. (4) Plastic trimming: Suitable tree type is natural garden head type and variable trunk type. The result tree adopts large-branched stripping and retracting trimming techniques to improve ventilation and light transmission conditions. For the sullen trees, the prosperous trees and the large branches open the skylights, retract the weak trees, short and rejuvenate; cultivate a reasonable canopy structure. (5) Flower and fruit management: Take the ring cutting, wiping the summer tip and spraying the flower-preserving fruit-preserving agent to protect the fruit in the small year, taking measures such as shaking flowers and removing the pests and diseases, deformed fruit, thin fruit and over-density fruit in the whole year. To ensure that after the second physiological drop, the number of fruit sets per 0.1 hectare is about 36,000. (3) Picking. The fresh-selling fruit is harvested when the coloring is more than 75%. The storage fruit is picked 7 days earlier than the fruit, and the fruit is collected by the “two-cut method”, and harvesting is prohibited in rainy days. (4) Quality characteristics. 1. Sensory characteristics: the fruit is round and round, the skin is orange-red; the skin is smooth and brittle; the flesh is orange-red, brittle and tender; the nucleus or non-nuclear, with a clear fragrance. 2. Physical and chemical indicators: fruit transverse diameter ≥ 55 mm, edible rate ≥ 75%, soluble solid content ≥ 13%, solid acid ratio ≥ 30.
