How are orange trees managed? How are orange seedlings cultivated and managed?

Before planting orange seedlings, you should first choose the land preparation, choose a well-drained plot, apply base fertilizer after deep ploughing the land, and dig a planting pit. The next step is to deal with the orange sapling, cut off the root system that does not grow well, prune it and put it in the planting pit, let its root system relax, and fill the soil and water the sapling after straightening it. During its growth period, it is necessary to weed in time and replenish the water it needs to grow, but if it rains frequently, it is necessary to drain it in time.

1. How to cultivate and manage orange seedlings.

1. Cultivation: Before cultivating orange saplings, it is necessary to select the land, choose a loose and well-drained plot, turn the land deep before planting, and apply some base fertilizer, and choose to apply farmhouse fertilizer and compound fertilizer. After preparing the land, dig a pit in the soil to a depth of about 60cm.

Orange seedlings should also be pruned first, prune the root system that is not growing well, and finally put it in the planting hole to let the root system relax, fill the soil after straightening the sapling, and finally pour the root water.

2. Management: The sapling should be loosened in time during the growth period, and the weeding should be done as soon as the land is found to have weeds. In order to make the young trees grow better, nitrogen fertilizer should also be applied, which can be supplemented with some phosphorus and potassium fertilizer.

Water should also be replenished in time to avoid excessive moisture content in the soil, so as not to lead to the death of seedlings. If there is no rainfall, you can water it every 10-15 days, and if the rain is more frequent, you should also do a good job of draining.

Second, orange seedlings are suitable for planting.

Planting orange seedlings can be planted in Guangxi, Jiangsu, Hunan, Hubei, Jiangxi, Sichuan, Gansu and other places, can be planted in slopes or mountains, and the organic content in the soil should be more than 2%, so as to be more conducive to the growth of fruit trees. Since it loves the sun, the planting area should have plenty of light so that it can meet the needs of its growth.

How to manage orange trees, in fact, orange trees are very easy to manage, we usually give them Siyu ** and then cut it, only once he has bugs, you can take a little medicine so that's fine.

1. Provide soil.

When cultivating orange saplings, it is necessary to mix the garden soil, cinder and river sand evenly, then sprinkle quicklime on the mixed soil, wait for the quicklime to be small, and then apply rotten organic fertilizer to the soil to improve the fertility of the soil, and finally plant the orange saplings into the soil.

2. Growth environment.

When maintaining orange seedlings, they should be placed outdoors in a sunny and sheltered place from the rain, so that the plants can photosynthesize around the clock and promote the growth of leaf buds.

3. Replenish water.

In the process of maintaining orange trees, it is usually necessary to water them every 2-3 days to soak all the soil, and in summer, the weather is dry and the temperature is high, so it is necessary to water the orange trees every day and spray them with water mist 2-3 times a day to improve the humidity of the plant growth environment.

4. Apply nutrients.

When the orange tree is in the seedling stage, it is necessary to supplement it with fertilizer about 3 times a year to promote the growth of the plant, and the fertilizer applied needs to use nitrogen fertilizer and organic fertilizer, supplemented by phosphorus and potassium fertilizer, so as to promote the growth of more branches and leaves of the orange tree.

5. Pruning of young trees.

Young trees are trees between one and two years after planting, and orange trees at this period are not yet suitable for bearing fruit, and should be fully used for vegetative growth. When the new shoots of the young tree grow to about 5 cm in length, the inflorescence branches that have neither flowers nor leaves should be cut off, so as to reduce the consumption of nutrients and allow the other strong branches to grow better. When leaving branches, each main branch leaves three to four side branches, and it is preferable to choose the strong ones to stay, and cut off the thin branches, which is conducive to cultivating strong branches with fruits.

Orange seedling management.

Saplings (1) are deeply ploughed and expanded in autumn and winter to mature the soil. Starting from the drip line on the periphery of the canopy, expand outward year by year, dig deep, wide fertilization furrows, fill in green manure, straw or organic fertilizer such as rotten farmhouse manure, cake manure, manure manure, etc., and cover the soil. (2) Intercropping or grass.

It is mainly shallow-rooted, dwarf leguminous plants, and has no symbiotic diseases and insects with green orange. The grass can be grown between the rows without intercropping, and the grass can be cut and covered with the tree tray or weeded with herbicides at the appropriate time. (3) Mulching and soil cultivation.

In the dry season, the inside of the tree tray is covered with grass. Thickness 10, 15 cm, the mulch should not come into contact with the trunk. In winter, you can use pond mud, river mud, sand or fertile soil near citrus orchards, with a thickness of 8 10cm.

4) Cultivating and weeding. Keep the tree tray free of weeds, and the orchard free of tall stalks and malignant grasses. The soil under the canopy of cultivated trees is cultivated several times a year, and herbicides can also be used to control bright oranges between plants and rows.

The fruiting tree is deep and expanded, and if the comprehensive expansion is not completed before the fruit, it will continue to be completed. The intercropping area decreases with the increase of the canopy, and finally only the managed roadway remains. Respect for mulching, soil cultivation, cultivating and weeding with young trees.

In the spring shoot germination period, flowering stage and fruit expansion stage, if there is a drought, it should be irrigated in time. Timely drainage through ditches during rainy seasons or when orchards are waterlogged.

Fertilization: Advocate more organic fertilizer, rational application of inorganic fertilizer, and leaf nutrition diagnosis formula fertilization. Limit the use of chlorine-containing fertilizers (no more than 250g of potassium chloride per year for fruiting trees to 500g plants).

Soil fertilization can be done by means of annular ditches, strip ditches and soil surface sprinkling, and trenches can be dug and fertilized at alternating positions on opposite sides of the crown drip line. Foliar top dressing: according to different growth and development periods and nutritional diagnosis, what is lacking and what is supplemented.

During the period of high temperature and drought, it should be used according to the lower limit of the concentration range, and the foliar topdressing should be stopped 20 days before fruit harvest.

Nitrogen fertilizer is the main fertilization of young trees, combined with phosphorus and potassium fertilizers, and a small amount is used many times. Fertilization was applied 6 8 times in spring, summer and autumn shoot extraction stage, and was applied at the shoot germination stage and old maturity stage, respectively. The top dressing of the top bud is increased from the pruning to the new shoot before turning green.

1 3-year-old young trees should be applied with 200 400g of pure nitrogen per plant, and the ratio of nitrogen, phosphorus and potassium should be 1:(:.

The amount of fertilizer should be increased year by year from less to more.

To cultivate orange seedlings, you need to turn the soil deep and apply urea as a base fertilizer, dip the orange seedlings in rooting powder, transplant and plant, and water the root water and maintain it normally. When managing orange saplings, you need to make sure you have plenty of light. In terms of watering, it is necessary to water according to the principle of seeing dry and wet.

During its growth period, nitrogen, phosphorus and potassium compound fertilizers need to be applied to promote growth.

To cultivate orange seedlings, it is necessary to choose loose and fertile plots with good drainage and ventilation for cultivation in hidden rows. Before planting, the soil needs to be turned deep and urea is applied as a base fertilizer to promote the growth of orange seedlings. Before planting, orange seedlings need to be dipped in roots with rooting powder, and then transplanted and planted.

When the orange seedlings are planted, they need to be moistened completely by applying rooting water to the roots. In the first month of cultivation, nitrogen, phosphorus and potassium fertilizers need to be applied every seven days to promote growth and allow orange seedlings to be planted.

To manage orange saplings, first make sure that the orange saplings have adequate light. Plant it in a sunny place and let it be maintained in full sun, the summer is hot, the light is strong, and proper shade is required. During the flowering period and before the expiration of orange seedlings, nitrogen, phosphorus and potassium compound fertilizers need to be applied to promote growth.

During its growth period, nitrogen, phosphorus and potassium compound fertilizers need to be applied to promote growth.

Orange seedlings have a greater demand for water, but the root system is not tolerant to stagnant water, so they need to be watered every three days in spring and autumn, once every half a month in winter, and once a day in summer. This can ensure that the orange saplings have sufficient water, and also avoid the accumulation of water in the acres of orange saplings, which will lead to root rot.

Newly planted orange tree fertilization should be applied diligently, mainly nitrogen fertilizer, with the application of phosphorus and potassium fertilizer, spring, summer and autumn shoot extraction period fertilization 5-6 times a month, each time each plant applied ammonium carbonate or urea catty. 1-3 year old young trees should be applied with 100-400g of pure nitrogen per plant, and the ratio of nitrogen, phosphorus and potassium should be as follows: (:

Advisable. Fertilizer and water management: (1) Fertilization principle: the needs of blood oranges for various nutrients should be fully met, and more organic fertilizers and rational application of inorganic fertilizers and formula fertilizers should be advocated. Fertilization was guided according to the results of leaf analysis, orchard soil analysis, and phenological period of blood orange.

2) Fertilization method: soil fertilization is the main method, combined with foliar fertilization. Methods such as annular furrow application, strip furrow application, hole application and soil surface fertilization are adopted.

3) Fertilization of young trees: diligent and thin application, mainly nitrogen fertilizer, with the application of phosphorus and potassium fertilizer, fertilization in spring, summer and autumn shoots for 5-6 months, each time each plant is applied ammonium carbide or urea catty. 1-3 year old young trees should be applied with 100-400g of pure nitrogen per plant, and the ratio of nitrogen, phosphorus and potassium should be as follows: (:

Advisable. Adult trees should be fertilized four times, namely germination fertilizer, fruit preservation fertilizer, fruit strengthening fertilizer, and fruit picking fertilizer.

The amount of fertilizer is generally 2-3 kg of germination fertilizer, and a load of manure water; 1-2 kg of phosphorus and potassium fertilizer + 1 kg of chemical fertilizer; 1-2 kg of fertilizer + 1-2 kg of phosphorus and potassium fertilizer; Fruit fertilizer (base fertilizer) is mainly organic fertilizer, and 50-100 kg of organic fertilizer + 1-2 kg of chemical fertilizer is applied.

4) Water: Irrigate when the soil is dry, and drain water when it is waterlogged.

Orange trees in different periods of fertilization are different, in planting, need to apply a nitrogen-based fertilizer, budding every 2 months to apply a mixture of urea and ammonium carbonate fertilizer, in the flowering period can be appropriate to apply some phosphorus and potassium fertilizer, fruiting needs to apply a nitrogen and potassium fertilizer.

When the orange tree planting is completed, it is necessary to carry out a fertilization, mainly apply nitrogen-based fertilizer buried in the material, do not fertilize too much, the amount of a plant can be about catty, so that the orange tree can absorb enough nutrients, adapt to the surrounding environment in a short period of time, and shorten the delay period.

When is the fertilizer budding period of the orange tree is essential, in the stage when the orange tree is just out of the leaves, it is necessary to supplement the nutrients, and it is necessary to apply fertilizer every two months or so, and each plant can be mixed with catty of urea and catty of ammonium carbonate for fertilization, which can make the orange tree grow more vigorously.

When the orange tree is flowering, in order to make the tree pregnant buds more, it is necessary to properly apply a compound fertilizer containing phosphorus and potassium, the dosage of a plant is about catty, and it is best to water the soil thoroughly at the fertilization time, so that the fertilizer is easier to be absorbed by the roots, and the effect will be better.

If you want oranges to grow bigger, you need to apply a fertilizer based on nitrogen and potassium, which can have the effect of strengthening the fruit, if you do not apply fertilizer when fruiting, it is likely to lead to the phenomenon of fruit drop, and the sweetness and quality of oranges will be relatively poor.

Fertilization after picking is mainly based on organic fertilizer, applied once every 2 months, so that the orange tree can grow more vigorously in the coming year, the amount of each plant is about 2 catties, before fertilization, it is also necessary to properly turn the soil, the roots will grow more robust, and the nutrition will be more conducive to absorption.
