Cultivation techniques of Chu orange
(1) Cultivate improved varieties and strong seedlings
Excellent varieties with large fruit, rich juice, few seeds or no seeds, slag removal, solid content above 1 1%, less fruit dropping or cracking before harvest and strong high and stable yield should be selected. Using Fructus Aurantii as rootstock to cultivate virus-free improved varieties and strong seedlings is the basis of high yield and high quality cultivation. Seedling raising requires well-developed roots and well-healed interfaces. The height of seedlings is more than 40cm and there are more than 3 branches. Focus on follow-up and strengthen the management of seedling raising with soil. Follow-up should choose loam with sunny, convenient water source, close to plantations, deep soil layer and high organic matter content. There are 1000 plants per mu, and the plant spacing is 60× 100cm.

(two) unauthorized changes in civil gardens and planting.
1: Rebuilding civil gardens and soil conservation
The whole park will be deeply overturned by blasting, and terraces with the same height will be built, roads will enter the park and water conservancy facilities will be provided. In the first half year of planting, the soil in the planting ditch (hole) is matured. The planting ditch is generally a little outside the center line of the terrace. When building terraces, topsoil should be filled into planting ditches. The planting ditch has a width of1.8m and a depth of 0.8m. It is filled with topsoil and layered with organic matter, such as municipal garbage, grass and corn stalks, with a dosage of 5000- 1 10,000kg per mu.
Step 2 plant
Planting density: about 82 plants per mu. The standard ladder is 4m wide, and each ladder is densely planted in a single row, with 4m spacing between permanent trees, and temporary trees are inserted between permanent trees. The plant spacing is 2m, and about 4 1 plant is planted per mu after one thinning.
Planting time: September in autumn is after the autumn shoots mature, or before the spring shoots germinate, after the leaves of the spring shoots turn green in mid-May in summer, and before the summer shoots germinate in early June.

Management of Soil, Fertilizer and Water in Orchard
1: orchard soil management;
In the adult sweet orange orchard, if the soil layer is hard and shallow, deep tillage and hole expansion should be carried out in autumn, and organic fertilizer should be applied to improve the soil and thicken the soil layer. Advocate planting grass or vegetables in orchards, green manure or covering grass between rows or plants, and implement no-tillage in orchards. Before the kindergarten is closed, it is strictly forbidden to intercrop crops such as tall stalks that affect the growth of sweet orange trees.
2. Fertilizer and water management in sweet orange orchard.
Young trees are mainly fertilized with nitrogen fertilizer, with appropriate amount of phosphorus and potassium fertilizer, and adhere to the principle of applying dilute and decomposed liquid fertilizer frequently and combining fertilizer with water. During fertilization, the new shoots are fertilized once before germination and once after self-shearing, and the energy is applied seven times a year (of which165438+1mid-October is the overwintering fertilizer).

(4) Reasonable shaping and pruning
1: young tree shape: sweet orange should be changed into trunk shape. The whole tree should cultivate 3-4 main branches, and each main branch has 2 lateral branches. The main branches and fruiting branches should be cultivated by methods such as budding, topping and pulling.
2. Pruning of adult trees: Pruning methods such as thinning, shortening and shrinking are adopted to achieve ventilation and light transmission of the crown and maintain the tree shape. It can be implemented: before flowering (from late March to early April), it is pruned in bud stage or before flowering.
