How to grow mandarin

1, the season is very important, the general planting season: mostly in winter, spring, autumn planting is also possible, depending on the situation (ground preparation), weather, labor and other conditions; generally with the seedling new shoots ripe to pre-sprout planting, must choose the right season.

2, there is also a planting specification: plant row spacing 2.5 × 3 (meters), 80 plants per mu, according to specifications.

3. Planting method: the rice field should be sorghum and planting pier. The mound is 30 cm high and 50 cm wide. Dryland should dig holes, apply enough basic fertilizer, plant with yellow mud slurry roots, drenched with fixed root water, after that, it should be moisturized every day to survive.

I. Post-planting management

1. Young tree management. The management of young trees is mainly based on plastic surgery. it should be noted that there are 4 shoots in one or two years (spring shoots, small full shoots, small summer shoots and white dew shoots); 3 times in three years (spring shoots, Lesser Heat-big summer shoots, White Dew front and back shoots); branch shooting for more than 4 years (spring shooting, autumn shooting or spring shooting, stack added slightly in late summer).

2. The method of shoot release. Each time the tip length is 15 to 20 cm, the top is promoted, and the branches are promoted, and each tip leaves 2 to 3 tips, and the final tip is not top.

3. The fruit tree is planted. It is necessary to pay attention to the cultivation of high-quality fruit branches, in principle, according to more than four years of trees to shoot, the standard is: more than 70% of the branches of the entire orchard begin to sprout, can be placed. The method is to manually erase early, sporadic new buds, to stay early, in order to promote more, neat, robust new shoots, usually mature in November and December.

Second, timely and appropriate amount of fertilization

1. Young trees (1-2 years old). Implement the principle of applying thin fertilizer frequently. Achieve one shoot and three fertilizers (sprouting fertilizer, strong shoot fertilizer, turning green fertilizer). Summer greening, winter soil and fertilizer application, green manure soil, cultivate soil strength.

2. Result tree. Re-apply "Greater Cold" fertilizer (pre-flowering fertilizer) autumn shoot fertilizer, pre-harvest fertilizer, supplementary application of flower fertilizer, Xiehua fertilizer, strong fruit fertilizer. The amount of fertilizer application should be determined according to tree age, crown size and fruit amount. Generally speaking, the amount of autumn shoot fertilizer applied each time is 0.5kg / plant for cake fertilizer and 0.25kg / plant for chemical fertilizer. The fertilization plan in other periods depends on the intensity of trees and the number of fruits.

Planting techniques and Management methods of Gongkan

1. Planting techniques of Gongkan

1. Land preparation and mound

The method is to first wrap the plough around the ground, and then smash or erect the mound according to the plant line. The mound is 100cm wide and 30 cm~40cm high. After that, the mound is expanded by the soil.

2. Build irrigation and drainage ditches.

To build irrigation and drainage ditches, a three-stage irrigation system must be used to dig deep ditches one year after planting, reaching a width of 40cm~50cm and a depth of 40cm within three years; the circular garden is 50cm wide and 50cm ~ 60cm deep.

3. Seedling requirements

Seedlings are required to come from disease-free parent trees, the seedlings are strong, the seedlings are strong, the leaves are thick green, the seedlings are above 35cm, and there are 3 branches; the grafted seedlings of sour orange or Jiangxi red tangerine rootstock have developed roots, and there are no quarantine STD pests, and the quality of seedlings meets the requirements of GB / T9659.

4. Planting time

If it is planted, it should be in the new bud before the next sprout. It can be divided into three periods: spring planting, autumn planting and winter planting. By month, spring planting is planted from February to April, autumn planting from October to November, and winter planting from December to early January.

5. Planting density and method

Planting density and methods must be mastered, planting 80 plants (350 × 230cm), 100 plants (330 × 200 cm) or 110 plants (300 × 200cm). When planting, the grafting interface should be exposed, the root system should be extended, the broken soil should be compacted, and the water of fixed root should be drenched, so that the new root can be sent out in about 20 days.

II. Methods of planting and management of Gongkan

The main results are as follows: 1. For the management of young trees: based on the principle of frequent and thin application, two fertilizers per shoot, shoot-promoting fertilizer was applied about 10 days before new bud germination, mainly with available nitrogen fertilizer. The new shoots were cut and fertilized with strong shoots. It is necessary to eliminate stagnant water in spring and summer, timely irrigation in autumn and winter, cover and moisturize; for 3-year trees after autumn shoots are mature, pay attention to control water, restrain winter buds and promote flower bud differentiation.

2. For crown management: in order to form a garden crown with early bearing and high yield as soon as possible, it is necessary to make reasonable shaping and pruning to make the crown develop evenly; to control the top advantage, the methods are: wire shaping and erasing control.

3. For soil management: use open space to plant legume herbaceous green manure, conserve water and increase fertilizer, and prevent soil erosion. Weeding covers autumn ploughing and water conservation, removes weeds from the tree plate, and covers the tree plate before early summer and early autumn, and begins to cultivate soil in winter in the third year after planting. The orchards in hilly and mountainous areas have been thoroughly turned over and improved within five years after planting. The forage is carried out for a long time at the end of autumn or in November-March combined with root cutting, water control and flower promotion. The method is to enlarge a hole with a length of 1 meter, a width of 0.5 meters and a depth of 0.4 meters on each side of the original planting hole, burying green manure, soil manure or rotten barnyard manure and wheat bran manure and applying lime. The direction of rotation expands once a year, and the acupoints expand year by year.

How many months does the mandarin mature?

Gongkan usually matures in January, which has something to do with the climate. We all know that Gongkan is known as "the King of Citrus in China". The fruit shape is beautiful, the fruit color is golden, the skin is thin and the core is few, the meat is crisp and has no residue, sweet honey, high sugar and low acid, rich flavor, it focuses on the dual advantages of the beautiful appearance of oranges and the delicate flesh and easy peeling of citrus, so it is difficult to compare with other citrus varieties and is known as the emperor of citrus. The maturity time of Gong orange and sand sugar orange is not much different, generally, it begins to mature gradually in late November, while that of horse water orange is relatively late, and generally begins to mature in mid-January. The management among Gong orange, sand sugar orange and horse water orange is basically the same, you can try.

After the introduction of the editor, how much do you know about Gonggan? Know the planting method of Gong mandarin, understand the planting technology and management method of Gong mandarin, those who are interested in Gongkan can have a try. I hope my explanation will be helpful to you all.
