Sugar oranges, which are fragrances of double-leaved plants, are one of the most popular citrus varieties of consumers in everyday life, and are more famously located in guangxi. The sweetness and taste of the carcasses is good。

Ii. Strategy and management of corruption
1. Plantation
Pre-plantation generally requires stationing to support the drying of the seed, even distribution, stretching of the root system, new landfills with no fertilizers, and compaction, full root water and soil moisture。
2. Young tree management
2. 1 fertilizer water management
Incentive fattening 7 to 10 days prior to each stub, mainly on the basis of fast-acting nitrogen fattening, and on the basis of extra fattening when freshly cut. During the growth of the plant, compound fertilizers, urea and corroded organic fertilizers are applied, and they are generally applied around the tree plate, so that the roots are not burned。
During the rainy season of spring and summer, the water must be eliminated in a timely manner, and in autumn and winter, drought and drought must be filled and covered in a timely manner. Care to control water after the autumn season has matured in order to contain the onset of winter and to promote the fracturing of flowers。
2. 3 flower protection
In order to contain the thawing, prevent the formation of the next year's bud, reduce nutrient consumption and promote the rapid formation of tree canopy. Spraying 920 is required。
2. 4 soil management
Roast orange cultivation should be deep-spreading, fertilizing the soil, prohibiting the planting of high-strength plants such as maize, wheat and so forth in the gardens, as well as rational gardening and weeding. The soil is deep (60 cm) and fertile. Soil ph values are 5. 5-7. 0. Orchard slopes are below 25 degrees. Parks should be planned with the necessary roads, drainage, water storage and ancillary construction facilities. When planning specifically, as far as possible, it should be centralized and built in good transport and water facilities。
3. Results tree management
3. 1 fertilizer management
Quick-activated nitrogen fertilizers are distributed with phosphorus, potassium fertilizers, which account for 30 per cent of the year. Weak trees and large flowers are subject to a moderate application of steady fruit fertilizers, which are nitrogen fertilizers and phosphate fertilisers 7-10 days before the fall。
3. 2 integrative trim
It's local, it's tree trim, it's proximate, it's radiant, it's stereo. The main branches (three to four branches) are distributed on the main branches, with the main poles divided between 30 and 50 degrees and two to three branches on each branch. Usually, when the third branch is formed, the central category is to be trimmed to one side to the other to produce the branches。
3. 3 disease prevention
Because oranges are weak against yellow dragons, they are particularly vulnerable to infection and incidence. It's the enemy of the sweet orange. Main symptoms: in addition to the occurrence of yellow stalks, the main characteristics of the diagnosis are the eutrophication of the blade base and edges, and the emergence of irregular foliage between the yellow and green phases。
In sum, it's all about the techniques and management of sugar orange growing, and friends who want to grow it first have to go to the environment to see if you can grow it and how good it is. Then what happens to the market, it is also important to have a full grasp of planting techniques and not to be blind。
