Can the fibrous roots of the sugar orange fruit tree that has just been planted for one year rot and

I just planted a sugar orange for a year.

Can the fibrous roots of fruit trees be saved? I would like to share some of my personal views with you. There are a few points.

The first point is that the tillage layer of the orchard is relatively shallow, and the tillage layer is not dug deep, or it has encountered heavy rainstorms caused by waterlogging. After the heavy rain, the stagnant water is not drained away in time, and the soil is soaked in water for a long time, so that the water content in the soil is increased.

Surplus, resulting in root hypoxia suffocation and root rot. The remedy is to dig the plough to a depth of 60 to 80 cm to avoid water accumulation and root rot due to heavy rain. with hydrated lime.

disinfectant solution for soil disinfection. Open a strip-shaped ditch and put fermented and rotted microbial organic fertilizer + phosphate fertilizer + hydrated lime. Cover the soil and restore the tree as soon as possible.

The second point is to bury organic fertilizer that is not well rotted, peanut bran, and apply too much fertilizer to cause root rot. The remedy is to dig a ditch and cut off the roots, put in phosphate fertilizer + Liangguoan + Wofengsu + garlic oil + hydrated lime to irrigate the roots and bury them regularly.

The third point is foot rot, root swelling, and stem base rot. The remedy is to loosen the soil of the diseased tree and sprinkle hydrated lime and disinfectant to disinfect it. In the diseased trees, rinse the roots with R. solanacearum + garlic oil into the ring type.

The fourth is the harm of root nematodes. By digging up the soil, it was found that the roots were swollen, the size of mung beans, and the black-brown root nodules were added, and the tree body declined, yellowed, and lost leaves, so it can be judged that it is root nematode disease. The remedy is to use avermectin EC + Gen Doctor No. 3 (Purple lavender) for diseased trees.

Nematodes are swept away) regularly for root irrigation and spraying. Let the tree recover as soon as possible.

After a startling experience, the prevention and control method recommends that everyone use methyl frost and mildew first.

Irrigate the roots once, and after a week with Bacillus subtilis.

Add humic acid to irrigate the roots once. In fact, the occurrence of root rot is also very related to water and fertilizer control, if the water is too large, the pathogenic bacteria in the soil will have the conditions to spread, resulting in the plant is not strong, and the resistance is low. If the fertilizer is not used sufficiently, the nutrients needed for the growth of fruit trees will not keep up, and the lack of resistance will also provide conditions for the spread of bacteria, and too much fertilization will cause the phenomenon of burning roots, so fertilization is really a university question, and you can make adjustments according to your own experience and the soil conditions of the garden.

There must be salvation, first of all, you must do a simple cleaning of the roots, and then apply more fertilizer, so that you can be saved.

Saved. You can plough the soil and get more sun, or you can dig up the soil and replace it with new nutrient soil. Then prune off the rotten roots. Scientific and reasonable fertilization and water control during the breeding period.

I don't think there's anything to be saved. If the roots of a tree rot, it may not continue to grow, so it is better to buy another tree and plant it.

If all the branches of the tangerine are cut off, its viability will be greatly affected, and it will even lead to the death of the tree. The photosynthetic cavity of trees is done through leaves, which are the basis for plant growth and development, and leaves are also one of the main organs for plants to absorb carbon dioxide and release oxygen. If all the branches of the tangerine are cut off, the tree will not be able to photosynthesize properly, so it will not be able to obtain enough nutrients and energy, and eventually lead to the death of the plant.

Therefore, it is recommended to only prune the unhealthy branches such as excessive growth, serious pests and diseases, dead branches and dead leaves on the sugar orange tree, and retain the necessary healthy branches to ensure the normal growth of the plant.

Hello dear, you can still live. Pruning method of sugar orangesWhen pruning sugar oranges, it is also necessary to use the correct pruning method. First of all, it is necessary to cut off the branches and leaves that the plant grows poorly or cannot grow normally to help the plant save nutrients, and at the same time, it is also necessary to cut off the branches and leaves of the plant that suffer from pests and diseases to prevent the plant from suffering from diseases, and it is also necessary to cut off the branches and leaves that the plant grows too densely to make the plant grow better.

3. Precautions Before pruning the plants, the pruning tools need to be disinfected in the wheel bench to avoid infection of the plants in the process of pruning, and after pruning, it is necessary to apply carbendazim solution to the pruning wounds of the plants, so that the pruning wounds of the plants can heal as soon as possible, and at the same time, it is also necessary to avoid water contact with the pruning wounds of the plants, so as to avoid plant rot. 4. In the later stage of maintenance, it is necessary to provide appropriate water for the plants, keep the soil moist, and also need to provide appropriate nutrients for the plants to improve the growth rate of the plants, and it is best to use nitrogen, phosphorus and potassium compound fertilizer when fertilizing the plants, so that the plants can absorb balanced nutrients and grow more vigorously.

Summary. Hello dear, sugar oranges, almost ripe, knocking off the branches will not affect the next year's fruit, on the contrary, it is better than letting the sugar oranges hang on the branches.

Sand tangerine, almost ripe, will it have any effect if you knock off the branches?

Hello dear, sugar oranges, almost ripe, knocking off the branches will not affect the next year's fruit, on the contrary, it is better than letting the sugar oranges hang on the branches.

The sugar orange is left on the tree to fall off naturally, which will definitely affect the flowering of the fruit tree and the quality of the flowers. Therefore, under the premise that there is time and conditions for the defeat of the year, it is recommended that it is best to pick or beat the secondary fruit.

Sugar orange trees with fruit will affect the quality of the flowers. The flower buds do not receive enough nutrients, and when they bloom, the number of flowers on the fruit tree is not as good as that much, and the quality of the flowers is not so good.

If there is no certain number of flowers and high-quality flowers, when it comes to fruiting, the number of young fruits that can be hung on the fruit tree is definitely not so much, and the quality of the young fruits is not so good.

So, you still have to take it off or knock it off.

Summary. Sand tangerine, almost ripe, will it have any effect if you knock off the branches?

The flesh of sugar oranges has a sweet flavor and is very popular in daily life. The main characteristics of golden autumn sand tangerine are: early maturity, seedless high yield, strong adaptability, medium and high resistance to canker disease, high sugar and low acid, delicate residue, seedless crisp and sweet.

The specific features will not be detailed in this article. What is the prospect of planting Morichong of golden autumn sand sugar oranges? First of all, the planting difficulty of Jinqiusha sugar orange is relatively low, and it is relatively easy to manage. The trees in the golden autumn are particularly vigorous, and there is no doubt about the abundance of envy; The appearance of the fruit is smooth and beautiful, the skin is smooth and delicate, and the waxy layer is thick and bright; The taste is crisp and tender, and the residue and soluble solids are also high.

What is the effect of pruning the main stem of sand sugar orange after 40 days of planting, new roots begin to grow, can be diluted with decaying manure water 2-3 times drenching, every 10 15 days to apply, 5 10 kg per plant, with the growth of young trees, gradually increase the concentration and amount of manure water, appropriate addition of urea to dissolve in the grinding manure water after drenching. Planting density The flat land is planted with a density of 3m between plants and 3m between rows, and about 70 golden autumn sugar oranges are planted per mu, while the slopes and hills are planted with a density of 3m between plants and rows, and about 80 golden autumn sugar oranges are planted per mu. In some areas of Liangguang and Yunnan Youhui, about 100 120 plants can be planted per mu due to the good light conditions, while in other areas, it is recommended to plant only about 60 80 golden autumn sand tangerines per mu.

By September, the application of nitrogen fertilizer and manure was stopped, and potassium fertilizer was applied once, and half a kilogram of potassium chloride was applied to each plant to promote flower bud differentiation. Kiss you have to trim it instead of knocking it off.

As long as the roots are there, they will sprout. Sugar oranges are managed in April.

Flowering and young fruit stage (first physiological fruit drop stage) in April

In early April, the tangerine continues to bloom, and it takes 2-5 days for a single flower to bloom from flowering to flowering, and there are also those that open and thank when the wind is strong, but it is not good for the growth of young fruits. The county's thank-you time is generally on April 6-10, and the first physiological fruit drop will begin after the thank-you. The first 5 days of fruit drop are generally caused by incomplete development of flowers, which is a congenital defect, and it is useless to keep these young fruits, so let them be eliminated naturally.

The fruit drop 5 days after the big thank you is caused by the production of a large amount of endogenous hormone abscisic acid by flowering, so it is necessary to spray in advance to protect the fruit. The first physiological fruit drop period generally lasts for about 25 days from April 1 to May 5.

1. Flower and fruit preservation: generally no foliar spray is carried out during the flowering period of March 25 and April 10. Foliar fertilizers containing nitrogen, phosphorus, potassium, trace elements and amino acids are selected, such as Yanwo foliar fertilizers containing amino acids.

Spray foliar fertilizer again 1 2 times between April 20 and 5 May. Flowering consumes a lot of nutrients, sprinkled in mid-April near the drip line on the periphery of the canopy at 15:15:

15. Feast fertile water-soluble fertilizer, each catty, promote the fruit to turn green, reduce physiological fruit drop.

2. Circumcision: Practice has proved that circumcision above the grafting interface is an effective measure to preserve flowers and fruits. The horizontal circumcision closure circle is to prevent the carbohydrates produced by the photosynthesis of the leaves from being transmitted downward, so that they can directly lead to the young fruits.

At the same time, the root system grows slowly because there is no carbohydrate**, and the fertilizer absorbed cannot meet the needs of concentrated pumping of summer shoots, so as to achieve the purpose of controlling shoots and reducing the second physiological fruit drop in the second half of May. The width and depth of the ring cutting should be used, and the time should be carried out in late April and early April.

3. Prevention and control of diseases and insects: the control objects include red spiders, aphids, leaf miners, scabs, etc. In general, there should be no disease in this April, and the disease should be dealt with in the month. In April, the light medication has no effect, and the heavy one causes the skin of young fruits.

Take care of it carefully, and wait and see, orange trees will shed their leaves and sprout new shoots in spring.

Summary. There are many reasons why the sapling tangerine tree does not take root, does not sprout, and withers yellow, let's talk about the four common reasons:

1) Seedlings. Some of the root system of bare root seedlings are seriously damaged when they emerge, and it is difficult for them to take root and germinate.

2) Soil. Soil compaction, soil hypoxia, and high soil pH.

What is the reason why the sand sugar orange saplings only bloom and do not bud after they live.

There are many reasons why saplings do not take root, do not germinate, and wither yellow, and talk about four common reasons: (1) Some of the root system of seedlings with bare roots are seriously damaged when they emerge, and it is difficult to take root and germinate. (2) Soil reeds were formed, soil hypoxia, and soil pH were high.

3) Water is dry in mountainous areas, and water is not drenched in time when there is a shortage of water; Low-lying paddy fields have poor drainage and excessive water to the roots. (4) Improper fertilization, excessive fertilization and root burning. Focus on the problem of burning roots, the spring rainy season is the most likely to fertilize and burn roots, fertilization He which dismantles (granular fertilizer) encounters rainy Zen jujube days, fertilizer melts and soaks the roots, the amount of fertilizer is slightly too much will burn the roots, if the young tree does not have roots only, it is equivalent to salt on its wounds, and it is strange not to burn the roots.

Young trees can only be fertilized after they are born, the amount of fertilizer should be less than more, should be light and not thick, the lack of fertilizer is easy to solve, the root burning is difficult to deal with, and it is better to lack slow source fertilizer than too much.

Pro, fertilizer countermeasures: pour water on the roots, dilute the remaining branch cavity fertilizer, and spray brassinin lactolide + potassium dihydrogen phosphonate. The young erector tree does not take root, does not germinate, and the leaves are yellowed Countermeasures: drenching roots or amino acids + spraying brassinin lactolide or amino acids.
