How do you get mandarin seedlings? How to grow mandarin oranges

My classmates and I are also fruit tree entrepreneurs, and the seedlings sold by Jianyang Zeyou Agriculture and Animal Husbandry are very good, growing strong, and the fruits are full and delicious.

1. Soil selection and fertilization: Choose a ventilated and sunny site for planting mandarin oranges, and make a box with a distance of 8 meters after deep turning of the soil. 2. Reasonable dense planting

At the beginning of planting, the plant spacing was 1 meter and the row spacing was 2 meters, and after the yield of mandarin oranges increased, the plant spacing was changed to 2 meters. 3. Field management: apply accelerated nitrogen fertilizer after the spring shoots grow to 5 cm, and topping treatment after the new shoots grow to 20 cm.

1. Select land for fertilization

Planting mandarin oranges should be ventilated to the sun, loose soil, deep soil layer of the site to build an orchard, and then the soil is turned deep to dry, and to apply farmhouse fertilizer to it, improve the fertility of the soil, after the planting is completed, the spacing of 8 meters should be used as a box, and four rows of 2 meters spacing ditch is dug on the surface of the box.

2. Reasonable dense planting

When planting mandarin oranges, it is necessary to select seedlings with good growth, no damage, no diseases and insect pests, plant them in the ditch dug in advance with a plant spacing of one meter, and then compact the soil at the roots, and water them once permeable, wait for the yield of mandarin oranges to increase, and take measures to move between the rows to change the plant spacing to 2 meters.

3. Field management

The growth rate of mandarin orange is faster, wait for the spring shoots of seedlings to grow to 5 cm, to apply fast-acting nitrogen fertilizer every 15 days to promote the growth of plants, after the new shoots grow to 20 cm, it should be topped to promote the germination of new branches of mandarin orange, and in September and October of each year, phosphorus and potassium fertilizer should be applied to mandarin orange to promote fruit development.

In order to make the seeds germinate, it is necessary to select high-quality seeds and give the seeds germination treatment. After the seeds are soaked, they are placed in a position with a higher temperature of elimination, and generally after 3 to 6 days, the seeds of the citrus will bud. After budding, it is sown in soft and breathable soil, generally about a week, the seeds can germinate, and after 10 to 20 days, the plants will emerge.

Mandarin orange is a late-maturing hybrid citrus variety, and the plant generally matures between February and March. Before planting, the seedlings need to be cultivated first, and then transplanted later. To promote the germination of the seeds of the plant, the survival rate of the plant can be improved, which is conducive to the rapid germination of the seed.

Select high-quality citrus seeds that are full and undamaged, and soak them.

Before planting, the seeds of citrus need to be washed with cold water, and after washing, they are soaked in carbendazim solution or potassium permanganate solution for 10 to 12 hours for sterilization and disinfection. After the seeds have swelled and soaked, they can be washed with cold water. After washing, the citrus seeds can be wrapped in a damp cloth that is placed in a warmer place for maintenance.

During the curing period, the seeds are dripping with water every day to replenish their water, and if the ambient temperature can be stabilized between 20 and 25 degrees, generally after 3 to 6 days, the seeds of citrus will bud. After the seeds are budded, they can be sown in the soil for cultivation, and citrus has strong adaptability, so it can be planted in loose, breathable and well-drained soil.

Choose soft and well-lit soil, loosen and apply basal fertilizer in advance, and then sow the seeds in the soil. When sowing, control the plant spacing and row spacing, the thickness of the soil is about 2 cm, and after sowing, cover with a layer of fine soil. The first watering should be fully watered, and the later maintenance needs to control the water, keep the soil moist, and after 10 to 20 days, the plants will emerge.

1. "Mandarin orange" has medium cold resistance, suitable for planting in citrus producing areas with an average annual temperature of more than 1, and the minimum temperature in winter is required to be not less than 0.

2. In the production, orange, red orange, citrus aurantium and citrus orange can be used as rootstocks, and there is no incompatibility with grafting with citrus aurantium, so avoid choosing citrus aurantium as rootstocks. In areas with high calories, avoid using strong rootstocks such as Volkamer and coarse lemon to avoid low acidity and fading the flavor.

3. "Mandarin orange" has strong growth, fruit hanging tree for a long time, and the demand for fertilizer and water is large, so the base fertilizer should be reapplied in production, and the base fertilizer is mainly rotten and fermented farmhouse fertilizer and compound fertilizer. In purple soil and barren slope land, the improvement of soil should be strengthened, more organic fertilizer and phosphorus and potassium fertilizer should be applied, and an appropriate amount of zinc and magnesium fertilizer should be supplemented to ensure that the leaf color is dark and green.

4. "Mandarin orange" has strong yield, less fruit drop in winter, excellent hanging performance, long fruit picking period, in order to avoid small fruit and large and small annual fruits, attention should be paid to fruit thinning and timely fruit picking according to the tree load in production.

When it comes to mandarin orange, everyone must be familiar with it, because its skin is thin and fat is rich in a variety of nutrients required by the human body, so it is deeply loved by everyone in life.

Mandarin grafting, in the production of hail can choose orange, red orange, citrus aurantium, citrus orange as rootstock, and citrus aurantium grafting incompatibility, avoid choosing citrus citrus citrus as rootstock in high calorie areas, avoid the use of strong rootstocks such as Volkamer, coarse lemon, so as not to make the fruit acid too low and make the flavor light, orange grafting is mainly characterized by fast growth and high yield, citrus aurantium is characterized by good fruit taste, good adaptability of fruit trees, strong drought resistance and disease and insect resistance.

The benefits of citrus cultivation are considerable, and many farmers are growing citrus. At present, many farmers use the grafting method to grow citrus, but different rootstocks have different resistance and adaptability. The rootstock is a plant that bears scion during grafting propagation, which not only has the role of fixing and supporting the scion, but also absorbs water and nutrients in the soil for the root system, which is the basis of the grafted seedlings of mandarin.

After planting the seedlings, the orchard should be inspected frequently, and the orchard should be inspected frequently, and the orchard should be checked frequently to see if there is any abnormal situation, and the corresponding measures should be taken, and then timely prevention and control. Emphasis is placed on the prevention and control of mites, butterflies, lice and anthrax. The resistance of mandarin oranges to canker disease is very low or even non-resistant, so mandarin oranges planted in areas with canker disease should pay attention to prevention and control work in spring and summer.

And in areas with huanglongbing, pay attention to the prevention and control of psyllids, and the prevention and control of pests and diseases is also one of the important conditions for the normal growth of mandarin oranges and the achievement of high yields.
