Which variety is more hardy in the cultivation of orange trees?

Hardy orange tree varieties include Longhui red navel orange, rock sugar orange, tarocco blood orange and so on. It has a certain cold resistance, can resist the low temperature environment of minus 9 degrees, has high yield, stable yield, and no size years.

Longhui red navel orange, rock sugar orange, tarocco blood orange, these varieties are relatively hardy, and the oranges produced are particularly good-looking.

Rock sugar orange, this variety is very hardy, and it can also be stored for a long time, and it is also very tasty

This plant is not very hardy, so it can only be grown in the south, so the temperature is more suitable.

Personally, I think the orange tree is relatively cold tolerant, but it can't withstand special cold, so it needs a warmer place to grow.

Its cold tolerance is very weak, so it must be well protected from the cold when planting, so as to bring high returns to yourself.

The conditions for high-quality and abundant yield of oranges are that the temperature of growth and development should be controlled at 18-35 as much as possible, and the soil layer should be deep and fertile, loose and drainage, and the soil needs to be kept acidic. Maintaining 7-8 hours of light every day can ensure the quality of the oranges, and the taste will be sweeter.

The conditions for orange cultivation are as follows

Soil: Oranges prefer deep, fertile, loose, well-drained, and permeable soils. It can be planted in mountains or on slopes.

Temperature management: The suitable temperature for oranges is around 37. When the flower buds are differentiated in autumn, the temperature is kept at 20 during the day and about 10 at night.

Fertilizer management: Oranges need to be fertilized at each stage of growth so that the oranges have adequate nutrients.

Light management: Oranges are light-loving plants and need a lot of sunlight during the growing season to ensure their normal growth needs. In summer, when the sun is strong, it needs to be shaded.

Water management: Oranges need to be watered frequently during the seedling stage. Reducing watering and frequency during the fruiting phase promotes sugar accumulation. In the rainy season, it is necessary to drain the water in time to avoid root rot.

Pruning branches: Pruning branches at the seedling stage is conducive to the growth of branch buds. Later repair of the canopy.

1.Hardy orange tree varieties include Longhui red navel orange, rock sugar orange, tarocco blood orange and so on.

2.Among them, Longhui red Jiangao navel orange is mostly ripe in November, has a certain cold resistance, can resist the low temperature environment of minus 9 degrees, its advantage is high yield, stable yield, no size year.

3.The Tarot coarse section of the Keyan is renamed blood orange is ripe in January and February every year.

4.Its advantages are storage resistance, high cold resistance, and more worry-free management.

The most hardy variety of the orange tree is the citrus, which can grow in an environment of minus 20 degrees Celsius, and is also more resistant to diseases, and when grown in an environment above 35 degrees Celsius, the plant will remain dormant. The petals of the lycine are spoon-shaped, the flower color is white, the leaves are broadly oval, oblate, and the edges have a regular serrated shape, the flowering period is in April and May, and the fruit ripens in October and November.

The most hardy orange tree is the goji orange.

Citrus is a deciduous shrub and small tree, with strong cold resistance, able to grow normally in an environment of minus 20 degrees Celsius, and has a strong ability to resist diseases, but it is not tolerant to salinity, and when growing in an environment with a temperature of more than 35 degrees Celsius, the plant will enter a dormant state, and the entire growth rate will slow down.

The height of the plant is 1 5 meters, the shape of the crown is umbrella-shaped, round-headed, the root system grows densely, the branches are oblate and cylindrical, the surface has longitudinal ridges, the color is green, it also has reddish-brown spikes, the length is 10 25 cm, the width is 2 3 cm, the top is sharp, and the bottom is flattened.

The leaves of the lycium are opposite, the shape is broadly oval, oblate spherical, the edge has a regular fine serrated shape, the veins on the surface are more obvious, and it also has fine hairs, the length is 2 5 cm, the width is 1 3 cm, the petiole is narrowly ovate, narrowly obovate, the length is 4 5 cm, and the width is cm.

The inflorescence of the lycine is cylindrical, the petals are spoon-shaped, the flower color is white, the length is cm, the width is 1 2 cm, and the flowering period is in May and June. The fruit of the lycium is nearly round and pear-shaped, with a length of 3 cm and a width of cm, the skin of the fruit is rough and dark yellow in color, and the fruit ripens in October-November.

Yan Zi said: Orange to Huaibei will become orange.

(1) Soil structure and texture.

The soil structure is best with aggregate structure, and the soil texture is better with special loam.

2) Soil pH

Citrus soil acid.

pH 6 0 6 5 is the most suitable alkalinity.

Generally speaking: sandy loam, loam is better, the soil is deep, rich in organic matter, loose and breathable, good drainage and irrigation conditions, low groundwater level, slightly acidic to neutral soil is the most suitable.

Growing Environment:

1) Spring and Season Day.

When the average temperature of the system stabilized above, navel orange bai began to germinate. The average daily temperature was 23 29 hours, and the growth and growth of the disease were the most suitable.

2) Navel oranges require an annual rainfall of more than 1000mm.

3) Navel orange is a fruit tree with strong negative tolerance, but sunshine is closely related to the high quality and high yield of navel orange. Insufficient sunshine, navel orange growth fruit and fruit coloring are poor, generally 1200 2200 hours of sunshine per year in the area can grow normally.

4) Navel oranges are suitable for growing in a soil environment with pH.

The reason why the leaves of the orange tree that have been planted for half a year begin to turn yellow is first ruled out as a lack of fertilizer, because it is generally planted with bare roots, and it is rarely planted with soil mass, and the actual recovery period after planting it is two months, and the actual growth is less than four months, and the soil quality of the garden is not too bad, and there is generally no shortage of fertilizer. The possible reasons are as follows:

1. Stagnant water, soaked and damaged roots.

2. When planting, the farmhouse fertilizer that has not been alcoholized is put in, and now the temperature of the farmhouse fertilizer alcohol has burned the roots, and it has basically lost the due role of the roots.

3. The base fertilizer is not mixed with the soil or there is no pure soil layer of about 10 cm between the roots of the new seedlings, so that the newly sprouted tender root tips are in direct contact with the fertilizer, and they cannot withstand the osmotic pressure generated by the concentration of fertilizer and lose water and wither.

It is also unlikely that fruit seedlings will develop orange disease due to high temperature and humidity.

1. Strengthen the fertility of the soil and enhance the tree potential. Young seedlings are weak and the roots are young and tender, so it is advisable to apply thin application frequently, and loosen the soil and weeds in time to eliminate weeds in time to save nutrients. Pay attention to irrigation and drainage, maintain moderate moisture, and spray new high-fat film to retain the effect of fertilizer and water, and effectively promote the strength of the tree.

2. Cut the shape of the tree to strengthen and promote fruiting. In the dense branches and foliage around the canopy, the pruning is sparse, the top branches are heavily pruned, and the inner branches are lightly pruned, so that the inside of the canopy is well lit, and the fruit is more and the quality is good. Apply callus antiseptic film to the wound of the knife scissors in time to promote wound healing and prevent germs from invading and infecting.

It is necessary to spray strong fruit at the bud stage, young fruit stage and fruit expansion stage, thicken the fruit pedicle, increase the amount of nutrient delivery, prevent flower fall, improve pollination ability, improve fruit setting rate, speed up expansion, and ensure high quality and high yield of fruits.

3. Promote flower differentiation and balance fruit rate. The size of the tree bearing fruit makes the bearing of the tree unbalanced, which not only affects the equilibrium income, but also affects the health of the orchard. It is necessary to promote Kao No. 2 once a year during the flower bud differentiation period, which can promote flower bud differentiation, inhibit the wild growth of summer shoots, strengthen flowers and improve pollination ability and fruit setting rate; At the end of autumn, you can re-brush Kao No. 2 to suppress the extraction of winter shoots, strengthen the nutrient metabolism of the tree, and lay a good foundation for flowering and fruiting in the coming year.

Fourth, the prevention and control of pests and diseases, to protect the safe wintering of trees. There are many pests and diseases that harm orange trees, and the common ones are mites, scales, leaf miner moths, anthracnose, etc., and the prevention and control should be based on the occurrence characteristics of various diseases and insects, combined with spraying control. At the same time, the new high-lipid film was sprayed to enhance the efficacy.

<>1. Temperature: The growth and development temperature should be controlled at 18-35 as much as possible, which is conducive to the fruit setting quality and growth and development of oranges. 2. Soil:

It is suitable for sandy loam soil with deep soil, fertile, loose and good drainage, and at the same time, it is necessary to keep the soil acidic, which is conducive to the quality of fruits. 3. Light: Maintaining 7-8 hours of light every day can ensure the quality of oranges and make them sweeter.

First, the conditions for high-quality and abundant oranges

1. Temperature. Generally speaking, the growth and development temperature of oranges must be controlled at about 18-35 °C, and too low temperature will reduce the quality of oranges.

2. Soil:The adaptability of oranges is very strong, the requirements for the soil are not very high, and they are more suitable for sandy loam soil with deep soil, fertile, loose and good drainage, and the soil must be kept acidic, so that the quality of oranges planted will be better.

3. Illumination. Orange Hengzi has very high requirements for the growing environment, and must keep the sail for 7-8 hours a day to prepare for light, so as to ensure the quality of the orange, and the taste will be sweeter.

2. How to choose oranges

1. Look at the shape of the fruit.

The center of high-quality navel oranges is symmetrical, and the fruit shape is relatively upright, while the fruit shape of ordinary navel oranges is asymmetrical and uneven.

2. Look at the color.

The color of high-quality navel oranges is very uniform and there is no obvious color difference, while the color of ordinary navel oranges is yellowish and has obvious color differences.

3. Look at the epidermis.

The epidermis of high-quality navel oranges is smooth and there is no oil bag sagging, while the epidermis of ordinary navel oranges is not smooth and the pores are very large.

4. Look at the orange navel.

The navel of a high-quality navel orange is closed, and the smaller the better, while the navel of a common navel orange is not closed and larger.
