Why do fruit trees have to be watered after fertilization? What s the point?

When fertilizing fruit trees, the first thing to know is that fruit trees mainly rely on the root hairs in the root system to absorb nutrients. When fertilizing fruit trees, it should be mainly at the protruding edge of the crown or slightly away from the trunk, not too close to the trunk, because there is a thick root system near the trunk, and there are fewer fine roots and root hairs, which is not conducive to the absorption of fertilizer. The organic fertilizer decomposes slowly, but the fertilizer supply cycle is long, and it can be applied deeply, and the fertilizer has high mobility and can be applied shallowly.

Fertilization of fruit trees should be carried out reasonably according to the growth period of fruit trees. Special water-soluble fertilizers should be used to promote rooting during the growth period of fruit trees, which can promote the growth of fruit tree roots and promote the growth of fruit trees. In the flowering and fruit-setting period, it has a good effect of protecting flowers and fruits.

During the fruit expansion period, water-soluble fertilizers for fruit expansion should be used to ensure the high quality and high yield of fruit trees. After fertilizing fruit trees, for closed orchards between rows or densely planted, shallow application can be applied between rows and between plants, and it is best not to harm or harm the large root system, so as to give full play to the fertilizer efficiency, improve fertilizer utilization rate, and achieve the purpose of increasing yield and income. Fertilization is an important part of fruit tree production management.

There are many wrong practices in the practical application process of fruit farmers, which have a great impact on fruit quality and yield. The importance of fertilization in phases is also very important. One-time fertilization will inevitably lead to fertilizer waste and even fertilizer loss.

In general, during fertilization, attention should be paid to the application of basal fertilizer in autumn, most of which should be applied during the swelling period of young fruits and 20 days before fruit coloring. Water is the carrier of fertilizer. Without water, nutrient cycling in fruit trees is difficult.

If there is water, it can easily freeze. If there is no water or little water, it will not freeze. If the compound fertilizer melts and is quickly absorbed by the fruit tree after the basal fertilizer is applied in the autumn, a large amount of nutrients will accumulate in the branches of the tree body and will not be deposited into the root system of the fruit tree with the decrease in temperature, and the water and fertilizer remaining in the upper part of the trunk will easily cause the trunk to freeze and rot.

Watering after fertilization can dilute the fertilizer very well, which can make the fertilizer better absorbed, which is more conducive to the growth of fruit trees and conforms to the growth law of fruit trees.

This can promote the absorption of fertilizer by plants, which can help the growth of plants, and can also avoid the concentration of fertilizer being too high, which can enhance the resistance of fruit trees and avoid the death of fruit trees.

Hello, you can water.

Fruit trees should be kept dry before fertilization, so that watering after fertilization is more conducive to fertilizer absorption.

In the process of maintenance, the principle of fertilizing first and then watering should be adhered to, so it can be watered after fertilization.

Fertilization and watering time.

Before fertilizing, it is best to keep the soil slightly dry, so that the fruit trees are slightly dehydrated. Watering after fertilization is more conducive to the absorption of fertilizer efficiency; It can be watered immediately after fertilization, or after the next day.

Re-water. When watering, we should pay attention to controlling the amount of water, if the amount of fertilizer is small, you can not add a large amount of water, so as not to dilute the fertilizer and affect the fertilizer efficiency.

In order to ensure the fertilizer efficiency when fertilizing, we can choose to apply water-soluble fertilizer in Haihai and Weihai in the evening of the previous day, and then water it again in the morning of the next day, which is not only conducive to the absorption of fertilizer efficiency, but also dilutes the excess fertilizer effect in the soil, so as to avoid root burning.

Fruit trees must be watered after fertilization. Otherwise, it is not good for the fruit tree.

At the time of planting, apply some fertilizer at the bottom of the pit as basal fertilizer, if no basal fertilizer is applied. The base fertilizer is best organic fertilizer, because the content of various elements of organic fertilizer is relatively low and safer, on the other hand, the fertilizer effect of organic fertilizer is relatively long, which is conducive to the slow absorption of fruit trees. Or spray foliar fertilizer with new high-fat film, and spray strong fruit tilling once before flowering, young fruit stage, and fruit expansion stage to thicken the fruit pedicle and improve the amount of nutrient delivery.

Prevent falling flowers, falling fruits, cracked fruits, stiff fruits, and deformed fruits, so that the fruits are beautifully colored, beautiful in shape, and in good taste.

<> especially chemical fertilizers, because it generally takes 10-30 days for planted trees to take root, and it takes a period of time for new roots to grow to strong roots. Grow new roots, at this time there is no need to apply any fertilizer, just ensure that they are not sunburned. When the tree is stronger, then start to apply thin fertilizer, and the fertilizer for small seedlings within 3 years is also very simple, basically phosphorus powder and ammonium nitrogen, with some farm fertilizer or organic fertilizer.

Avoid the application of raw fertilizer to cause fertilizer damage, produce root burning, and affect the growth and development of the root system. Secondly, the amount of organic fertilizer can be applied according to the fruiting situation of the fruit tree, and 1500 kg of organic fertilizer can be applied per mu during the fruiting period of the fruit tree. In the later stage, it will lead to excessive growth of the tree, affecting flower bud differentiation and fruit development.

It is recommended to apply basal fertilizer as little as possible, spray foliar fertilizer and new high-fat film more, and at the same time, it can be combined with spring irrigation, top application of chemical fertilizer, mainly nitrogen and phosphorus fertilizer, with an appropriate amount of potassium fertilizer.

The formation of carbohydrates is closely related, if the chlorophyll content in the fruit tree is reduced, the leaf color will change to light green or yellow-green, photosynthesis will be weakened, the carbohydrate content will also be reduced, and for the fruiting tree, the taste and flavor of the fruit will also be reduced. Urea has high nitrogen content, strong water solubility, quick effect, and stable chemical properties, and is one of the more commonly used chemical fertilizers for fruit growers. Urea is used as top dressing, which can promote the growth of fruit trees and improve the photosynthetic function of leaves during the critical period of growth and development.

Of course, you can, because the nutrient requirements of fruit trees are very large at this time, so applying these two fertilizers can solve the problem very well.

Yes, but you should apply less fertilizer, if you apply more fertilizer, it is easy to burn the fruit tree to death, so that the fruit tree can not grow well.

Yes, because urea is meant to disperse nutrients and make the roots of fruit trees stronger.

Compound fertilizer should not be used immediately after the fruit tree is planted, otherwise it will burn the fruit tree's tie at this time.

I think you can put a little fertilizer, which is conducive to the nutrient absorption and growth of fruit trees.

1. Newly planted fruit trees should not be fertilized. The root system of the newly transplanted fruit tree has not yet grown and matured, and it is easy to burn the roots with fertilizer.

2. When fertilizing fruit trees, it should be applied around the fruit trees, and the scope of fertilization can be determined according to the shadow cast by the crown of the fruit tree on the ground, and under the shadow of the fruit tree, draw a circle along the shadow of the fruit tree, and be careful not to touch the roots of the fruit trees, otherwise it will burn to the roots of the fruit trees.

3. Fertilizer should be applied once before the fruit tree blooms to ensure that the flowers are kept, fertilizer should be applied once after the flowers fall to ensure the fruit rate, fertilizer should be applied once during the growth of the fruit to ensure that the fruit tree bears fruit, and fertilizer should be applied once in the later stage to ensure the growth of the fruit and become larger.

Perennial plants grow in pots, older, roots grow cross-grown in pots, crowded with each other, intertwined roots, affect the growth of new roots, and the ability to absorb nutrients is significantly weakened.

It is good to plant it in the ground, and it is good to plant it, apple trees.

The growth is inseparable from three things: sunlight, air, and water. When turning the pot, change the soil with new soil, apply base fertilizer, and water again, and the apple tree will grow immediately.

However, when watering, it is best to water the rainwater received when it rains, or change the pot The operation of changing the potted plant to another pot is called repotting. There are two situations in potted plants that need to be repotted: one is that as the seedlings grow, the growth of the root group in the pot is restricted.

Part of the root system is pierced from the pot hole.

out, or exposed to the soil surface, at this time the plant should be promptly small.

More than <> years of apple tree potted plants have adapted to the soil inside the pot, and it is no problem if the apple tree is not injured and does not change the original soil composition. On the contrary, turning the pot also plays a role in loosening the soil in disguise.

Second, apple trees belong to the wood family and are not as delicate as flowers. Watering immediately is because turning over the potting will cause damage to the roots, weaken the ability to absorb water, and the potting soil is not too wet. Too much watering will cause the root wounds to rot, and when new roots grow, you can increase the amount of watering.

After turning the pot, the potting soil should not be dry, otherwise the roots of the potted plant will wither, first of all, the apple is a fruit tree that needs more water, except for the week before the fruit is picked and the dormant period can not be watered, the other phenological periods need different amounts of water. Potted apple trees are usually watered a few days before repotting, so the moisture of the soil is very low under normal conditions, and the operation of changing to another pot at this time is called repotting. There are two situations in a potted plant that need to be repotted:

One is that as the seedlings grow, the growth of the root group in the pot is restricted. A part of the root system from the pot hole, or exposed to the soil surface, at this time should be timely the plant has a small pot to a large pot, expanding.

Yes, not watering will burn the fruit tree to death, the so-called burning, generally after fertilization, watering can dilute the fertilizer, in addition to the fertilizer and water chemical reaction, the fruit tree is more likely to absorb the substance.

As long as it is not over-applied fertilizer, there is no great harm to the fruit tree itself, except for the waste caused by the high fertilizer loss rate. Watering fruit trees after fertilization has the advantage of a high conversion rate of fertilizer use and is not limited by natural weather conditions.

Fertilization is not watered, the trunk of the fruit tree opens its mouth", the fruit tree is fertilized, there is no water cooperation, the fruit tree can not absorb it, that is just put the fertilizer in the soil, let the fruit tree look at it, just like a person is particularly hungry, put a bunch of delicacies in front of you, but can not eat, is it very uncomfortable? However, there are times when the fruit tree does not need to be watered after fertilization or needs to be watered after a few days.

If a fruit tree wants to be good, the root system is the key. The root system is like the stomach of the fruit tree, and the nutrient absorption depends on the root system, and when the root system is developed, the fruit tree will be strong. However, the root system of fruit trees grows in the soil, and if the soil conditions are good, the root system will naturally be good, and the yield and quality of fruit trees can be guaranteed.

Good roots require good soil, and good soil requires good fertilizer, so scientific and rational use of fertilizer plays a vital role for fruit trees.

In view of the fact that my hometown is mainly planted with apples, I will share the precautions for apple fertilization:

1. Organic and inorganic fertilizers need to be used together.

Organic fertilizer has the effect of improving the physical structure and chemical properties of the apple orchard soil, organic fertilizer has the characteristics of long-lasting and slow fertilizer effect, and chemical fertilizer has the characteristics of fast fertilizer effect but short fertilizer effect.

Second, nitrogen, phosphorus and potassium, medium and trace elements are used together.

The growth of roots, buds, branches and leaves of fruit trees and the differentiation of dormant flower buds, flowering and fruiting, fruit expansion and ripening, etc., will be regular and absorb various nutrients in proportion.

All nutrients are equally important for apples and are indispensable to each other. Therefore, while using organic fertilizer to deep plough and transform the soil, we must pay attention to the role of chemical fertilizers such as nitrogen, phosphorus and potassium, medium and trace elements, and pay attention to the application of multiple compound fertilizers, so that the proportion of various nutrients is coordinated, so as to lay the foundation for the good growth of fruit trees, high quality and high yield.

3. Nutrient balance** to maximize fertilizer efficiency.

In the annual cycle, the apple tree recovers the absorption function from the root system, to the budding, the formation of short branches, the differentiation of flower buds, the amount of nitrogen, phosphorus and potassium required is increasing, and the amount of nitrogen, phosphorus and potassium required in the fruit expansion period is also more, and the three elements required will be significantly reduced after that.

The nutrient absorption roots of apple trees are mainly distributed in the deep soil, so the organic fertilizer is mixed with nitrogen, phosphorus, potassium and part of the nitrogen fertilizer and then applied as basal fertilizer, and some nitrogen, phosphorus, potassium and medium elements are applied separately or mixed with trace elements for page spraying when the fruit tree is in urgent need of nutrients, so as to reduce nutrient loss and improve fertilizer utilization.

All healthy fruit trees require a high amount of fertilizer. Although all plants need 16 elements, which are considered essential, a large number of elements are the ones that are consumed the most from the soil. It is important to fertilize regularly to keep the trees healthy.

The macronutrients that we should apply regularly are nitrogen (N), phosphorus (P), potassium (K), calcium (Ca), magnesium (mg), and sulfur (S). Carbon, hydrogen, and oxygen are also nutrients that are needed in large quantities, but these elements are provided by air, water, and organic matter.

There are two types of fertilizers that can distinguish between phytonutrients.

Chemical fertilizer. These fertilizers are processed minerals or chemical salts.

Whether you're applying organic or conventional fertilizer, it's important to remember that only apply fertilizers that are lacking in the soil and needed by the plant. Timing of fertilization is important to protect the groundwater table and waterways from unintentional contamination from runoff and leaching. You can only fertilize the fruit trees during the year when they will use the fertilizer you provide in the soil.

Fruit trees in Sichuan can grow on a wide variety of soils, but in most places, fertilization improves plant vigor and health. To get an accurate picture of the nutrients present and deficient in your orchard, you should take soil samples. When you get the results of the soil test, you will be able to provide nutrients that the soil is lacking.

Determine the appropriate time for fertilization.

Fruit tree base fertilizer should be applied in autumn: Timely application of base fertilizer in organic orchards can not only improve the soil, stabilize and increase yield, but also make organic fruit trees grow robust and enhance the stress resistance of organic fruit trees. Basal fertilizer is best applied after fruit harvest.

Because the autumn application of basal fertilizer coincides with the third peak of the root growth of organic fruit trees, the roots injured by ditching and digging holes are the easiest to heal and can send out new roots, which is conducive to the recovery of the root system. When applying basal fertilizer in autumn, the root system has a strong ability to absorb water and fertilizer, which increases the nutrients in the tree and increases the concentration of tissue cells, which is conducive to the cold resistance of organic fruit trees to overwinter. The application of basal fertilizer in autumn is conducive to the decomposition and transformation of organic fertilizer in winter and spring and the continuous release of nutrients, and timely supply of organic fruit tree flower bud differentiation. Autumn application of basal fertilizer can improve the fruit setting rate of trees. Fertilization standard fruiting trees are generally not less than "1 kg of fruit and 2 kg of fertilizer".
