[cultivation techniques]

I. selection of land and land preparation

Fructus Aurantii has strong adaptability and is born in the environment of sunny, moist, fertile soil, good drainage and neutral pH value. After selecting a suitable forest site before planting, dig a pit of 1 meter deep and 1 meter wide, and the sloping land can be dug into fish-scale pits to prevent soil erosion. The pit is filled with dead branches and fallen leaves for planting trees.

II. Planting methods

1. Seed collection and seed treatment

The cultivation of Fructus Aurantii is mainly propagated by seeds. Collect seeds when they mature in November. Seed coat reddish brown. A fruit contains three seeds. The seed coat is leathery, the embryo is yellow and white, it is not easy to absorb water. Sprouting was accelerated by wet sand stratification method after harvest, and a layer of wet sand was stored in one layer. Radicle bulge appeared in 50-60 days, seedling bed (small bed) was sowed, sowing or strip sowing, deep 2~3cm, and seedlings could emerge at the beginning of April.

two。 Sowing method

When the seedlings grow out of 3-5 true leaves, the seedlings will remain strong and get weak. When the seedling height was 35~40cm, one plant was planted in each hole according to the row spacing of 400cm × 300cm.

3. Seedling stage management

The seedling stage should be often watered, fertilized and promoted growth.

4. Planting and management

The seedlings of Fructus Aurantii grow slowly, so it is necessary to strengthen the management of young trees. After transplanting, weeding was ploughed and weeded 4 times a year, and manure and compost were applied once a year in spring and autumn. Cut off shade branches and weak branches in winter. Promote the tree to be flat, erect and sturdy. It is usually 5 or 6 years before the fruit begins to hang. Every year when weeds grow in spring and summer, they should loosen the soil and weed, and water them in time when they are dry. Fertilizer was applied three times in March in spring, June in summer and November in winter to promote growth. According to the modern dwarfing branch drawing technique, the fruit can be hung up to 3 or 4 years in advance. In the second year after planting, the young tree bends the main pole when it grows to 1-1.5 meters; let it divide into secondary branches, and then use the same Faraday technique to blossom and bear fruit on the third-and fourth-grade branches, and the branches spread out in all directions to achieve early fruit, more fruit, and increase economic income.

[pest control]

I. Diseases

1. Branch blight

Branch blight is mainly harmful to plant branches. At the initial stage of the disease, light yellow or light red spots appeared on the branches, and then expanded into irregular brown spots. In the later stage, the edge of the lesion protrudes from the surrounding tissue, the middle gray depression, the epidermis cracking, producing acicular black spots on the ulcer spot, which is the conidium of the bacteria. If the ulcer spot surrounds the stem, it will wither the branches and leaves above the diseased part and seriously affect the growth of the plant.

Control method: before and at the beginning of the disease, the leaf blight was prevented and treated with Bordeaux solution of 1purl and 400.

II. Insect pests

1. Aphids

Aphids mainly harm shoots and buds.

Control method: satisfactory control effect can be obtained by spraying 40% dimethoate 2000 times aqueous solution.

[harvest processing]

The fruit is immature, the pedicel contains more tannin, and the taste is astringent and sour. After several frosts after Frosts Descent in November in winter, the fruit stalks were picked when they turned reddish brown. Cut off the fruit branches, store them in a cool place and ripen for 7 to 10 days. It can be sold not only in fresh products but also in dried juice. It can also be refined to cut off the fruit and remove the spotted stalks.

Fructus Aurantii is suitable for warm and humid climate. But can not bear the air is too dry, like sufficient sunshine, moist environment growth, the best temperature is between 20-30 ℃, the soil requirements are not strict, acidic and alkaline soil can grow, strong adaptability. Fructus Aurantii has a variety of uses, the wood of Fructus Aurantii is relatively hard and can be used as building wood; the trunk of Fructus Aurantii is straight and luxuriant, which is very suitable for landscaping.
