How to grow emperor oranges

I. preparation of improved varieties

(1) Seedling selection: in the early stage, we need to choose good isolation conditions to facilitate irrigation and drainage, the soil layer is deep, loose, fertile and slightly acidic, and the land that has not been planted with citrus is used as the seedling base. select varieties suitable for species growth and maintain the quality of tribute.

(2) seed treatment: before sowing, the soil is ploughed white, ploughed repeatedly, the soil is finely broken, and sufficient mature organic fertilizer is applied. The seeds were quarantined and treated with 55 °C warm water for 50 minutes before sowing. The mother plant of a single plant with stable character, high yield, stable yield and high quality was selected as the scion. The scion was grafted after detoxification treatment, and the spike nursery was established. The mother garden for the production of mandarin seedlings was established, and the scions were grafted from the ear-picking orchard (grafting tools, materials must be strictly sterilized). Stable, early-bearing and high-yielding Gong mandarin seedlings were produced by the above methods for field production and stable citrus seedlings for field production.

Second, the choice of garden land

Select the sand-soaked land with loose soil, good permeability, good root depth, suitable for the growth of trees, suitable for the growth of mandarin and no other crops as the production base, press green deeply and apply enough base fertilizer before planting.

III. Planting of seedlings

(1) planting season: winter and spring planting, autumn can also be used, general seedling new buds mature until planting buds.

(2) planting specifications: plant-row spacing 2.5X3 (m), 80-100plants per mu, with more than two branches, suitable for root system development, green leaves, disease-free and disease-free.

(3) the pruning treatment of seedlings: first, cut the seedlings into two or three needles, the height of the seedlings is 20-30 cm, and the roots are cut off moderately.

(4) Disinfection of seedlings: soak in 800 times of Wanling + 500 times of Nuotanning for about 1 minute and put it in a cool place.

(5) Root treatment of seedlings: dig a root, take some yellow mud, prepare paste with appropriate amount of water, and cool and dry the pulp roots of seedlings slightly after sterilization. When the treated seedlings are planted on the ground that has been completed, the paddy field should be deep ditch and high border, dryland should be burrowed, and sufficient base fertilizer should be applied. When planting, the root system should be naturally expanded, the trunk should be upright, the soil should be pressed layer by layer, the soil should be loosened and tightened, and the soil should be pressed from outside to inward. the depth of buried soil should be slightly higher than that of the root neck, and it should be moisturized every day in order to survive.

Planting techniques and Management methods of Emperor Citrus

I. planting techniques of Emperor Citrus

Soil digging planting holes: pulling distance, digging and planting points, hole depth and width 80cm, then pressing green manure 50cm deep, backfill 40cm high planting; field ridging planting: 8 meters with trench (60-80 60cm wide, 40-30cm deep), 2 ridges per box (1.5 m wide, 4 m center distance, 20-30cm ridge height). When planting, the root system of the seedling is appropriately trimmed and placed in the center of the planting hole to stretch the root system and straighten it. While filling the soil, the seedling is raised gently and firmly, so that the root system is closely connected with the soil. Pour enough water to fix the root, make a 1m plate around the seedling and cover it with bran shell for germination.

I. planting and management methods of emperor mandarin

1. Fertilizer and water management

(1) the demand for various nutrients of blood orange should be fully met, and fertilization should be advocated. Fertilization was guided according to the results of leaf analysis, orchard soil analysis and blood orange phenology. Soil fertilization is the main method, combined with foliar fertilization. Use annular groove application, groove application, hole application and soil surface diffusion methods.

(2) fertilization of adult trees

Fertilization for adult trees is very important, and it is also necessary to have skills to apply four times of fertilizer, that is, budding fertilizer, fruit protection fertilizer, strong fruit fertilizer and fruit picking fertilizer. Generally speaking, the amount of fertilizer applied is 2-3 jin chemical fertilizer, 1 load of dung water, 1-2 jin phosphate-potassium fertilizer + 1-2 jin chemical fertilizer, 1-2 jin chemical fertilizer + 1-2 jin phosphorus-potassium fertilizer, and 50-100 jin organic fertilizer + 1-2 jin chemical fertilizer. (4) moisture: the soil is irrigated when it is dry and drained when it is stagnant, so that it will not die.

(3) fertilization for young trees

Young trees should pay attention to more fertilization, and not too much each time, mainly nitrogen fertilizer, combined with phosphorus and potassium fertilizer, 5-6 times in spring, summer and autumn shoot emergence period, (3, 5, 6, 7, 9, 12 months). Apply 0.4 jin of ammonium bicarbonate or 0.2 jin of urea each time. For 1-3 years, the young trees should apply 100-400g pure nitrogen per year, and the ratio of nitrogen, phosphorus and potassium should be 1.0: (0.4-0.5): 1.0, so that the young trees can have nutrition.

2. Soil management

Deep holes should be added and the mature soil should be enlarged, the planting of tall plants such as corn and wheat in the garden should be prohibited, and reasonable intercropping and weeding should be done in the orchard.

Can the emperor spray citrus during the flowering season?

In addition to flowering, do not give medicine, so as not to affect pollination and fertilization, other times can be given medicine, young fruit period to pay attention to reduce the concentration can. When spraying, you can add micro-supplement fruit force + micro-supplement boron force, spray before flowering, can strengthen flowers and improve fruit setting rate; spraying after Xiehua can promote the development of young fruit evenly, which is beneficial to fruit preservation.

Emperor mandarin is characterized by fine and crisp meat, light color, no residue, less core, sweet import, deeply loved by the general public. But it is not easy to plant an emperor citrus tree. It takes some effort to take care of it. Only in this way can we grow good fruit.
