The planting methods are consistent, and the planting methods are as follows:
1, soil management
It is necessary to dig holes and solidify soil, prohibit planting tall plants such as corn and wheat in the garden, and do a good job in rational intercropping and intertillage weeding in the orchard.
2. Fertilizer and water management
(1) Fertilization principle: To fully meet the needs of citrus for various nutrient elements, it is advocated to apply more organic fertilizers and rationally apply inorganic fertilizers and formula fertilizers. According to the results of leaf analysis, orchard soil analysis and blood orange phenology, fertilization is guided.
(2) Fertilization methods: mainly soil fertilization and foliar fertilization. The methods of annular furrow application, strip furrow application, hole application and soil surface fertilization were adopted.
(3) Fertilization for young trees: diligent fertilization and thin fertilization, with nitrogen fertilizer as the main fertilizer and phosphorus and potassium fertilizer as the auxiliary fertilizer, 5-6 times in spring, summer and autumn, and 4 times in adult trees, namely germination fertilizer, fruit protection fertilizer, fruit strengthening fertilizer and fruit picking fertilizer. Generally, the amount of fertilizer applied is 2-3 kg of chemical fertilizer and one load of manure. Fruit-keeping fertilizer 1-2 kg phosphorus and potassium fertilizer+1 kg chemical fertilizer; Strong fruit fertilizer 1-2 kg chemical fertilizer+1-2 kg phosphorus and potassium fertilizer; The fruit picking fertilizer (base fertilizer) is mainly organic fertilizer, and each plant is applied with 50- 100 kg organic fertilizer+1-2 kg chemical fertilizer.
(4) Moisture: Irrigation when soil is dry, and drainage when water accumulates. Plastic trimming 1, principle. Adjust measures to local conditions, prune trees, properly raise and lower them, and ventilate and transmit light to achieve three-dimensional effect. 2, plastic surgery. The trunk is 20-40cm high and the main branches are scattered on the trunk. The branching angle of the main branch is 30-50 degrees, and 2-3 auxiliary main branches are left on each main branch. Generally, after the third main branch is formed, the central trunk of this kind is cut off and twisted to one side to form a fruiting branch group.
prune
(1) Young trees: mainly light pruning. After selecting the extension branches of the class center and the main branches and the extension branches of the auxiliary main branches, moderate or even severe pruning is carried out, and the growth balance among the main branches is adjusted according to the pruning degree and the direction of cutting buds. In addition to properly thinning the over-dense branches, the inner branches and weaker branches in the middle and lower part of the crown should generally be retained.
(2) Initial fruiting stage: continue to select short cutting to treat the trunk extension branches at all levels, erase the summer shoots, and promote the autumn shoots to be robust. In autumn, measures such as ring cutting, root cutting and water control are taken to promote the flowering of Wangshu.
(3) Full-fruiting period: the fruiting branches, falling branches and declining branches are retracted in time, and the light-blocking branches, dead branches and insect branches are cut off.
Orange Tree
Citrus is an evergreen tree with white flowers in early summer. In late autumn, this fruit is called orange, which tastes sweet and sour. The fruit is edible and the peel can be used as medicine.
Small trees, 2-3 meters high. Dense branches and dense leaves, acupuncture is rare. Leaves alternate, usually oval, tapering at the apex, wedge-shaped at the base, inconspicuous serrations at the leaf margin, and small but inconspicuous wings. Hua Xiaobai, sepals yellow-green, petals 5. The fruit is oblate or steamed bread-shaped, with a longitudinal diameter of 4.5-6 cm and a transverse diameter of 6.5-7 cm. The base is flat or convex, with 4-8 shallow radial grooves on it, and the top is slightly concave. The peel is easy to peel, crisp and fragrant with white inner cotton wool; Capsule 1 1- 12 petals; The column is empty, sweet and sour; More than 20 seeds, oval, yellow-brown. Fruit ripening period is 65438+mid-February.
Citrus tree, a small evergreen tree of Rutaceae, is native to China and widely distributed in the provinces south of the Yangtze River. It is about 3 meters high. Branchlets are thinner, glabrous and usually spiny. It blooms in spring and matures in February 10 ~ 10.
Orange trees are evergreen all year round, with dense branches and leaves, neat tree posture, blooming flowers in spring, and heavy yellow and yellow-green fruits in autumn and winter are extremely beautiful.
