How do you make apples color faster when growing apples? What are some coloring tips?

Unbalanced nutrient content is the main cause of poor coloring of apples. Generally, do not use excessive nitrogen fertilizer in the early stage, especially excessive nitrate nitrogen, which is easy to cause difficulty in coloring in the later stage. Magnesium and iron deficiency will affect photosynthesis, affect the production of nutrients in leaves, strong fertilizer and water management, moderate moisture, sufficient and timely fertilization, coordinated ratio of nitrogen, phosphorus and potassium, which is conducive to pigmentation, increase the application of organic fertilizer, stop applying nitrogen fertilizer when close to coloring, and appropriately increase phosphorus and potassium fertilizer.

Near-maturity, irrigation should be controlled, such as real drought.

<> practice has proved that the outer layer of the paper bag is picked first, and then the inner bag is picked after 3 days, and the fruit has an adaptation process. It will not be in a dark environment, suddenly exposed to direct sunlight, especially pure paper bag fruit, 2 bags are better than 1 bag picking.

This is the key to ensuring high-quality commercial fruit. The fruit is required to grow in the bag for about 100 110 days, and the double layer of the red fruit bag is best removed in two parts. The fruit coloring of 5 fruits at high altitude is fast, and the bag can be removed 15 to 20 days before the normal picking of the fruit, and the fruit is colored at low altitude.

After the apples are bagged, under normal circumstances, the time to pick the bag is generally in the autumn. Therefore, after picking the bag of apples, we should pay attention to the autumn pruning. Autumn is mainly to improve the permeability of the inner chamber of the apple tree, to increase the light for the fruit, after picking the bag, we also have to pick the leaves of the fruit tree, mainly to remove some leaves that will block the fruit from receiving light.

At the beginning of the pouch, the rosette leaves next to the fruit are removed, and then about 8 cm near the fruit are removed after the bag picking is completed.

We need to do a good job of watering the apples before picking the bags. Because it is not allowed to be watered after the bag is removed, if it is too dry, then it can only be watered with small water. Autumn is mainly to improve the permeability of the inner chamber of the apple tree and increase the light for the fruit, because the effect of light on the coloration of the fruit is very large.

The main objects of autumn pruning are long branches, competing branches and some long fruit branches under the canopy. Especially for potash fertilizers, don't apply potassium fertilizer unrestricted because the orchard is severely deficient in potassium.

The way to make apples color faster is to choose the right variety and let the apples get enough sunlight. Tips for coloring apples are: Use a reflector to reflect the sun's rays on the surface of the apples two weeks before the apples are picked, and the apples will be evenly colored after two weeks.

The first point is that you should pay attention to regular watering, which is a very good effect, the second point is that regular fertilization can make the apple color quickly, and the third point is that the best way should actually be carried out regularly, and the grafting effect is very good.

Apples are a very common fruit in our daily life, and they are cultivated in a very large area in our country. In order to ensure the quality and yield of apples, bagging is an essential job. After bagging, it is necessary to pay attention to picking the bag in time, but many people will find that the coloring of the apple after picking the bag is not very good.

So how can you make apples change color quickly after picking them? Now let's see!

Autumn scissors. After bagging, under normal circumstances, the time to pick the bag is generally in autumn. Therefore, it is necessary to pay attention to the autumn pruning of apples after bag picking.

The main purpose of autumn is to improve the air permeability of the apple tree and increase the amount of light on the fruit, which has a great influence on the coloration of the fruit. But the main objects of autumn pruning are long branches, competing branches and some long fruit branches under the canopy. Make sure that each leaf and fruit of the apple tree receives even light, or open the gap by hanging branches, which will also increase the light.

Leaf picking. After picking the bag, we also need to pick the leaves of the fruit tree, mainly to remove some leaves that will block the light of the fruit. When the bagging begins, pick the rosette leaf next to the fruit, and then pick the leaf about 8 cm next to the fruit after bagging.

When picking leaves, you should pay attention to picking around 9 a.m., and it is not suitable to pick at noon on a sunny day to avoid burns. First, the leaves that are closer to the fruit are cut off for about a week, and then the shading leaves, pests and diseases, and old yellow leaves around the fruit are removed. However, it is better to keep the functional leaves and avoid the decrease in photosynthetic efficiency caused by over-picking.

Fruit swirling. The main purpose of crop rotation after leaf picking is to ensure that each fruit receives even light. When it comes to fruit, it's important to ensure that the dark side of the fruit gets plenty of light and good color.

About a week after bag picking, when the coloration rate of the fruit on the sunny side reaches about 70%, the fruit rotates. Rotate the fruit 90 degrees or 180 degrees. Convert the shady side to the sunny side to ensure that the shady side is also fully illuminated.

When turning the fruit, be careful to force it and not too hard to avoid the fruit falling. The fruit is best turned twice. If the fruit cannot be fixed after transferring, it can be fixed with scotch tape.

Water and fertilizer management. We should water the apples well before picking the apple bags. If it is too dry, only water it with small drops.

In most cases, the poor coloring of the apple picking bag is caused by flooding after picking the bag, so pay more attention. Secondly, it is necessary to control the amount of fertilizer, especially basic elements such as nitrogen, phosphorus, and potassium. If these three elements are in excess, it is the main cause of poor fruit coloring.

Therefore, the amount of fertilizer to be applied should be strictly controlled, especially potassium fertilizer. The orchard is severely deficient in potassium, and potassium fertilizer cannot be applied without restrictions.

1. The nutrients in the organic fertilizer and phosphorus and potassium fertilizer are relatively comprehensive, which can make the apple fruit grow and develop well and be conducive to coloring. Potash fertilizer is conducive to the accumulation of sugar and the formation of protein, and enhances the red coloration of fruits. From late July to mid-August, potassium fertilizer can be applied to the soil, and potassium dihydrogen phosphate solution can also be sprayed on the foliar surface.

If the special compound fertilizer for multi-element high-effect trees can be applied in the ditch or hole, the coloring period of the red variety can be advanced by 7-12 days. 2. Control the negative planting of fruit trees to properly thin flowers and fruits of apple fruiting trees, control the yield, make the tree growth stable and robust, and the leaf-fruit ratio is appropriate, which is conducive to fruit coloring. 3. Control the application of nitrogen fertilizer, excessive application of nitrogen fertilizer in scientific water supply or application of fast-acting nitrogen fertilizer before fruit coloring, which will affect the red coloring of the fruit, generally after August to the fruit harvest, do not apply nitrogen fertilizer.

Moreover, it is necessary to ensure that the water is appropriate, drain the water in time when it is waterlogged, and water it appropriately in the morning, and do not soak in large water. , the orchard and fruit trees are ventilated and light-transmitting, which can promote good coloring. 5. Lay reflective film.

Balanced fertilization.

Potassium can increase the sweetness of the fruit and promote the coloration of the peel, but some studies have shown that too much potassium can affect the coloration of the fruit. When potassium is recommended, calcium and magnesium can be applied together to promote coloration. Mitigate the negative effects of excess potassium and control the amount of nitrogen fertilizer, especially in the later stages of fruit expansion.

Excessive nitrogen content in cells will first promote the conversion of sugar into amino acids and proteins, and reduce the accumulation of sugar in fruits. Secondly, nitrogen promotes the growth of branches and leaves, which affects nutrient transport and distribution and light. Third, nitrogen promotes the synthesis of chlorophyll in the peel and delays the degradation of chlorophyll. Studies have shown that the regression coefficient between the coloration rate and the nitrogen content of leaves in apples is negative 31. Therefore, in the later stage of fertilization, we must reduce the application of nitrogen fertilizer, apply organic fertilizer scientifically, and must apply fertilizer in a balanced manner, and scientifically proportionate all nutrients to meet the needs of fruit trees in different growth periods.

Fujinmen high potassium water-soluble fertilizer can be used to speed up veraison and increase the accumulation of dry matter in fruits.

Do it when you cut it in winter"The big branches are bright, and the small branches are shouting", leave less large branches, more small branches. Before apple coloring, cut off the upright branches, shading branches, weak branches and too many long branches on the periphery to improve the ventilation and light transmission conditions inside the canopy and promote the coloring of the fruits in the inner chamber and the middle. 2.

A silver reflective film is laid under the tree to improve the light conditions in the lower part of the canopy and promote fruit coloration. Laying a membrane can be used for 2 to 3 years. 3.

Picking leaves and turning fruits. During the fruit coloring stage, remove the leaves that block the fruit, and gently turn the fruit so that the shade is facing the yang. Divide 2 to 3 turns, do not rotate too much at a time, so as not to hurt the fruit stalk or turn the fruit off.

New Red Star Spray"Red Apple No. 2", Red Fuji spray"Red Apple No. 3", spray 1000 times the liquid one month before harvest or 500 times half a month before harvest. 2.Spraying ABT10 green plant growth regulator can promote coloration, increase apple weight, increase sugar content, and reduce preharvest fruit drop.

Apple Word Copy, Apple Word Copy, Apple Word Copy, Apple Word Copy, Fourth, Fruit Bagging The bagged fruit surface is clean and smooth, pollution-free, and brightly colored. Here's how:

After setting the fruit bagging (spraying a fungicide before bagging), go to the bag before coloring, if it is a double-layer bag, go to the outer bag first, and then go to the inner bag after an interval of 3 or 5 sunny days. You can also put a plastic film bag, the color is red as well, no longer go to the bag, and you can pick the fruit with the fruit when you pick it.

When you buy an apple in the market, you will observe its shape to some extent.

The color of apples still has a great impact on goods.

Some friends who grow apples may find that they are not colored, what is going on? Generally speaking, it is caused by the following major reasons, so let's analyze it for you!

Reasons why growing apples is not coloring:

1. Blindly pursue high potassium and avoid too much potassium fertilizer.

Recently, in order to further expand the fruit, many fruit farmers have begun to apply pure potassium to their fruit trees.

This approach is risky and requires a lot of practical experience, not blindness.

This is because a lack or excess of potash will cause apples to be uncolored.

For the sake of safety, high-potassium compound fertilizers are still recommended for fruit farmers with little practical experience.

In view of the fact that it is now autumn, the weather is cooler, and the apples are still in the slow expansion period, it is best to apply the base fertilizer and high potassium compound fertilizer and bio-organic fertilizer together to save labor and labor.

At the end of the month and the beginning of September, apply the bottom fertilizer to avoid excessive nitrogen.

7?Excessive nitrogen application in August will cause the apples to turn yellow and not color after bag picking.

At the end of August and the beginning of September, it is best to use balanced compound fertilizer, and must not apply high nitrogen compound fertilizer or urea, which has eliminated the impact on the coloring of fruit trees.

Fruit farmers who apply high-nitrogen and high-phosphorus compound fertilizers must apply the apples immediately after the apples are picked.

3. Do not pick the bag too early or too late.

Some fruit farmers pick bags too early, which will cause the apples to color first and then fade, returning to green.

Picking the bag too late will cause yellowing and not coloring.

Bag picking is generally from late September to early October.

It generally takes about 100-120 days for apples to grow in a bag, so it is best to pick the bag in two parts.

Bags are generally picked 10-15 days before the fruit is harvested.

Bag picking sequence: first inside the crown, then outside; Pick the dense tree first, and then pick the translucent tree; Pick the low-end bags first, and then the high-end bags.

When picking the bag, the double bag first tears the outer bag, and then removes the inner bag after 3 to 5 days.

When picking up the single-layer bag, tear the bottom of the single-layer bag or tear the bag into several strips longitudinally, and then remove all of them after about 5 days to prevent sunburn from sun exposure.

4. The tree body is shady and the light is insufficient.

This is a common phenomenon in fruit tables at present.

In addition, in addition to the above reasons, the fruit tree bears too much fruit and the load is too large; Poor quality of paper bags leads to poor greening, and it will also cause apples not to color.

Okay, the above is to share all the content with you, if there is no color phenomenon in planting apples, most of the above aspects are not done well, growers still need to pay attention to it, if you think this article is good, you can collect it!

That's all for the reasons why apples don't color, welcome to read other agricultural content on cucumber network.
