Can mangoes be pruned on a rainy day Is the weather suitable for pruning mango trees right now?

The weather is now suitable for pruning mango trees.

Mango cultivation techniques.

Planning & Reclamation.

Choose a place where the climatic conditions are suitable, the soil layer is deep, fertile, the soil is not easy to compact, there is no water accumulation, and the orchard is built near the water source. The orchards of the larger Huzhouhong should be divided into small areas according to the topography, and shelterbelts, drainage and irrigation systems, roads and other facilities should be planned. The garden should be ploughed and harrowed, and the tree heads, thatch, and mango should be removed.

The slope is opened according to the contour and the mountain line or terraced fields.

Preparation for planting. 1. Planting density varies according to climate, soil fertility and varieties. At present, the planting density is 5 m 4 m (33 mu 3 m (44 mu mu) or 4 m 3 m (55 mu mu).

In order to increase early gains, planting begins at 4 3 m and can be thinned into 6 m 4 m after harvest 3 to 5 years later.

2. Preparation and book of planting holes: dig holes 2 to 3 months before planting, 80 cm wide and 70 cm deep, apply 20 to 30 kg of well-rotted pigs, cattle manure or soil miscellaneous fertilizer per hole, superphosphate to 1 kg, and mix fertilizer with topsoil back to the hole.

Colonization. It is better to colonize from June to August. Planting can also be carried out in the southwest and south from September to October, subject to irrigation conditions.

If the seedlings are bagged, they can be planted from March to May in non-arid areas. It is better to colonize on cloudy days or before rain. Planting with bare root seedlings should keep the root system stretched; If you use bagged seedlings for planting, you can't step on the compacted soil mass.

The planting depth should be based on the flat soil surface of the root neck. After planting, drench the root water and cover it.

Fertilize. 1. Nitrogen and phosphorus fertilizers are mainly used for fertilization of young trees, and potassium fertilizers are appropriately combined, phosphate fertilizers such as superphosphate and bone meal are mainly applied as basal fertilizers, and top dressing is mainly nitrogen fertilizers. After planting, start topdressing when the shoots are pulled out 1 to 2 times, and apply topdressing once in March, May, July and September, apply 10 to 20 grams of urea per plant each time, and apply compound fertilizer in September.

If there is a drought, 1 to 2% liquid fertilizer or 1:4 of dilute stool water can be applied, and the amount of fertilizer used in the second year can be doubled. From June to August, organic fertilizer was added in combination with the expansion of the holes.

Apply 50 kg of green manure per plant, 20 to 30 kg of pig and cow manure or soil miscellaneous fertilizer, or 1 kg of peanut cake and superphosphate.

2. The fertilization of fruiting trees is mainly nitrogen and potassium fertilizer, and the amount of potassium is not less than nitrogen, and is combined with phosphorus, calcium and magnesium fertilizer. Specifically, do the following four times of fertilizer:

1) Flowering fertilizer: Apply flowering fertilizer from October to November. Within 4 meters of the crown (the same below), apply 150 grams of urea and potassium sulfate or 250 grams of compound fertilizer to each plant. As the canopy increases, the amount of fertilization increases accordingly.

2) When the amount of flowering is large, apply 100 to 150 grams of urea per plant after flowering, or add 1% urea or potassium nitrate in combination with spraying as root topdressing.

3) About 30 days after the strong fruit fertilizer flowering is the rapid growth period of the fruit, and it is also the spring shoot extraction period of young fruiting trees. At this time, nitrogen and potassium fertilizers should be applied 1 to 2 times to 15 days before harvest, or used as topdressing outside the roots to ensure the nutrients required for fruit growth.

4) Post-fruit fertilizer should be applied immediately after fruit harvesting, and fast-acting nitrogen fertilizer can be applied before and after fruit harvest in the harvest year, with 150 to 200 grams of urea per plant, and then organic fertilizer and phosphorus fertilizer can be applied.

Summary. Hello! Generally, pruning should be done within a few days, and the lower branches are slightly larger, the top branches are slightly smaller, and the buds will be relatively neat. Before or after pruning, fertilize to promote budding.

Hello, what medicine to hit mango after mango pruning does not become flowering.

Technical measures such as ring stripping, circumferential cutting, twisting branches, and bending branches are used to control the growth of branch tips and promote the differentiation of flower buds. However, depending on the strength of the tree, these measures can be taken if the tree is vigorous, the management level is high, and the soil fertility is high.

I'm not a flower catalyst.

Hello, what's that.

Golden Mango. What's wrong with Jinhuang mango.

Hello, please describe your question in detail, I can easily answer it for you.

I planted Jinhuang mango, after picking, I prune and prune and do not produce branches, what to do if it blooms again, hello! A scrambling pruning should be done in a few trillion days, and the lower branches should be slightly larger, the top branches should be slightly smaller, and the buds will be relatively neat. Before or after pruning, it is necessary to fertilize and promote budding.

Then it is necessary to fertilize the flowers, that is, start fertilizing after the inflorescence appears, and do a good job of protecting the flowers and fruits after flowering.

The question is what to do if it is pruned and blooms again.

I'm not going to spend or urge flowers now.

Hello, there is no other way to prune and bloom again but to prune.

Summary. It is recommended that you spray [Zhuangguo Tiling] to thicken the fruit pedicle before flowering, young fruit stage, and fruit expansion period to improve nutrient delivery. Prevent falling flowers, falling fruits, cracked fruits, stiff fruits, deformed fruits, and make fruits.

It is recommended that you spray [Zhuang Fruit Tiling] to thicken the fruit pedicle before the mango flowering, young fruit stage, and fruit expansion period to improve the nutrient delivery. Prevent falling flowers, falling fruits, cracked fruits, stiff fruits, deformed front return fruits, and make fruits.

It's not flowering, I'm flowering after pruning.

Mango flowers and fruits are generally treated with gibberellin, naphthalene acetic acid, mequat and butyrylhydrazide. These drugs are growth regulators and are very helpful for fruit development of plants. But we must control the concentration, if you use too much, it will also cause drug damage, and then not only will not help the effect of losing the base, but will inhibit its growth.

In addition, it is also necessary to supplement fertilizer appropriately to provide certain nutrients for the plants.

After pruning, mango trees should be applied with disinfectant and antiseptic drugs to prevent bacterial infection, and the specific application agents include potassium chromate solution, ether copper sulfate solution, sensitive branches, canned phenol chlorosulfonate (bromine), etc. Potassium chromate solution has antiseptic, antiseptic, anti-caries, anti-inflammatory effects, dosage, standby at room temperature, with 25 grams of potassium chromic acid and 1 liter of water liquid as a standby agent; Ether copper sulfate solution acts similarly to potassium chromate solution, dosage, preparation method to 3 grams of copper thioate and 1 liter of water liquid; Phenol chlorosulfonbis(bromine) canned solution dosage 1:200-1:

300, the standby agent is dissolved in 50 liters of water in 250 ml canned phenol chlorosulfonate (bromine). In addition, if diseases such as germs have been found in the pruning of mango trees, bacterial insecticides such as copper-zinc inducers and astrocarbendazim can also be used to control them.

1. Paint white branches.

After heavy retraction, the branches and their wounds are exposed to the sun, especially in the south and southwest, and the cortex is directly exposed to the scorching sun. In severe cases, the bark cracks to expose the xylem, causing the death of the manuscript or the whole plant. Whitening agent can reduce branch damage.

The whitening agent is prepared with 10 kg of quicklime, 1 kg of stone sulfur mixture, 1 kg of salt, 1 kg of animal oil and 40 kg of water.

2. Thinning shoots and promoting branching.

A large number of adventitious shoots will be extracted in different parts of the branches, and even multiple new shoots will germinate at the same bud position, such as prompting the branches to provide photosynthetic products to the roots as soon as possible. In order to protect the branches from the scorching sun and enhance the absorption capacity of the root group, 1-2 shoots can be left for a large number of adventitious buds, and the rest can be erased. After 2-3 times of new shoots are ripe, then according to the distribution of branches and the growth of branches, thin the shoots as appropriate.

In the early stage, the number of shoots left is large, and then gradually decreases. The branches are reasonably distributed, the nutrients are concentrated, and the newly formed canopy of Brother Jane is strong.

3. Foliar fertilization.

The management of retracting and regenerating orchards should be strengthened, and at the same time, soil fertilization should be used as the main fertilizer, supplemented by foliar fertilizer, 5%-10% urine, decomposed peanut bran soak, magnesium sulfate, potassium dioxide phosphate or other fertilizers can be used.

4. Insect protection.

There are many pests that damage leaves at the tender shoot stage. It should be sprayed in time for prevention and control.
