How to prune the planting of Maogu mandarin oranges

Strengthen the management of soil fertilizer and water in navel orange orchards: During the rapid expansion period of navel orange fruits, phosphorus and potassium fertilizers should be increased to create a deep and permeable soil structure. In the rainy season and dry season, it is necessary to improve the microclimate of the orchard, improve the relative humidity of the air, and avoid excessive dryness of the peel and too much change in the moisture of the pulp to cause fruit cracking.

Do a good job of ground covering, tree tray or inter-row mulching, straw, rape stalks, wheat stalks, enhance the orchard's drought resistance and water retention capacity, regulate temperature and humidity, and ensure the balance of soil moisture.

Timely control of pests and diseases: special attention should be paid to the prevention and control of scale insects and rust ticks. Agent coating fruit anti-cracking:

Before and after the second physiological fruit drop, 150 mg |l and 200 mg of 7 l of gibberellin solution coated on the umbilicus of young fruits. The anti-cracking effect is obvious, and it also has the effect of protecting the fruit. Coating the fruit with 200 mg of 7 liters of gibberellin plus methyl tobusperm 800 times liquid on mild first cracked fruit can make the cracked wound heal quickly and rarely**.

At the time of budding, choose methyl dichloride powder, diazinon granules, etc., add fine soil and mix evenly and sprinkle on the soil surface of the tree plate, once every 7 days, 2-3 times in a row; When the diameter of the flower bud is 2-3mm (when it is white), the crown is sprayed with sulfur and phosphorus, trichlorfon, etc.; Remove the infested flower buds as soon as possible and concentrate on deep burial or boiling; Deep ploughing of garden soil in winter can eliminate some overwintering pests and pupa.

1.Choose loose, fertile, well-drained and irrigated, leeward slope or paddy field for gardening.

2.With a row of 3 2 meters, 111 acres or row of plant spacing, 133 acres of planting specifications, dig 80 cm wide, 60 cm deep pit or ditch, each pit put 50 kg of organic fertilizer and 1 kg of calcium, magnesium and phosphorus fertilizer, green manure (weeds) 30 50 kg and soil mixed well back to the pit, the soil is about 30 cm higher than the ground, before the spring germination, about 15 days after the beginning of spring planting.

3.At this time, the roots have begun to be active and the survival rate is high. In areas with good irrigation, autumn planting is also acceptable.

After planting for about a month, the seedlings basically survive, and some thin manure water plus urea or compound fertilizer is applied. In the future, before the germination of new shoots and before the old maturity of the branches, apply a tap and shoot fertilizer, and the fertilizer is basically fast-acting fertilizer.

Mogu mandarin name "murcott."", "Honey Tangerine", or "Honey Murcott."", a hybrid of wide-skinned orange and sweet orange, known as tangors, was bred in 1913 by the Miami Agricultural Laboratory in Florida, USA. In the 70s, Professor Lin Pu of the Department of Horticulture of National Taiwan University introduced this variety to the northern region of Taiwan for trial planting. Due to the high sugar content, good flavor and rich flavor, thin and juicy skin, and later ripening than banana mandarin, the price in the Taiwan market is much higher than that of banana mandarin, and the cultivation area is increasing year by year.

In recent years, there have also been introductions and trial varieties in southern Fujian.

When the spring shoots grow to 5cm long, leave 2-3 strong buds in different directions on each branch tip, and the principle of leaving the buds is: sparse and sparse, sparse and short, sparse and strong, too strong branches, leave 6-7 leaves for topping; Erase all the summer shoots; Before putting autumn shoots (early to mid-July), erase scattered buds and cut off branch tips, the position of the cut should not be too high or too low, preferably between the 6th and 7th sections. Autumn shoots are released in mid to late July in Guilin.

If the tree is weak or the tree shape is not compact, a small amount of late autumn shoots can be left according to the situation, and the rest and winter shoots can be erased. In winter, on the basis of ventilation and light, reasonable distribution of branches and compact crowns, cross branches, shade branches, long branches, diseased and insect branches, weak branches, and dead branches are cut off, and the garden is cleaned at the same time.

The main production area of Sichuan Maogu mandarin is the southern region of Sichuan Province, China, with Maoxian County and Xuyong County as the main production areas.

Fellow, I really didn't understand, I can be more specific.

Maogu oranges are a high-quality citrus in Muli County, Liangshan Prefecture, Sichuan Province. This variety has a delicious taste, thick skin, full flesh, many juices, rich aroma, rich in vitamin C and minerals. The growing environment of Sichuan Maogu mandarin is very suitable, with long sunshine hours and suitable temperature in winter, which is very conducive to the growth of citrus.

The production area of Maogu mandarin is relatively small, and the unique growing environment and production technology make the taste of Maogu mandarin unique and more precious than the mold state. From December to February, it is the harvest season for mandarin oranges. Through years of cultivation and development, Maogu mandarin has become a well-known citrus brand in Sichuan Province and even the whole country.
