Do you know how to fertilize fruit trees scientifically?

Fertilization is an essential step when planting fruit trees, but many farmers do not know how to fertilize fruit trees, and some people think that autumn fertilization is already done, because the trees do not grow all winter and do not need to be fertilized in the spring. In fact, this understanding is one-sided, I will give you a specific introduction to the reasons why spring fertilizer is applied and how to choose fertilizer.

1. Reasons. 1. Most of the fertilizers applied last autumn were turned into organic fertilizers through the photosynthesis of autumn leaves. The growth of crops requires a combination of organic and inorganic at any time.

Therefore, we should apply fertilizer in spring, and the organic and inorganic fertilizer with high nitrogen three fertilizers in spring meets this demand.

2. Fertilizer has the timeliness of utilization.

For example, by examining changes in the phosphorus content of trees, it was found that the phosphate fertilizer that had been top-applied last autumn was not transferred to the trees in large quantities until May of the following year. This suggests that it takes several months for phosphorus to be utilized. The spring topdressing part is used for germination, leaf development, flowering, most of the effect is slightly slow, and it can be effective after flowering.

3. The combination of fertilizer and water is conducive to the development of trees.

After a winter, the tree loses a lot of water and needs germination water in the spring. In the management of fruit trees, empty water is generally not watered, and fertilizer and water should be combined at any time. Wearing fertilizer when watering the buds in spring is beneficial for the development of the trees.

Second, the selection of top dressing types.

Most people think that spring is the peak period for vegetative growth, which requires a lot of nitrogen fertilizer, so it is not appropriate to apply urea alone. Nitrogen is conducive to the growth of branches and leaves, phosphorus is conducive to root development and branch thickness, and potassium is conducive to the efficient allocation of nutrients. In the fertilization management of fruit trees, it is necessary not only not to apply autumn base fertilizer, but also to completely rely on top dressing, that is, the so-called "substitute top dressing", and do not overemphasize the application of autumn base fertilizer.

Bombing. "The correct approach should be based on base fertilizer, supplemented by top dressing. This method is more scientific and reasonable, through scientific and reasonable fertilization can not only greatly improve the yield and quality of fruit trees, but also prevent the occurrence of fruit tree diseases and pests.

Be sure to choose the right fertilizer, but also should prescribe the right medicine, timely pruning of branches and leaves, regular spraying of pesticides, to ensure sufficient light, do a good job of water and fertilizer, do a good job of drainage and gout, timely pruning of branches and leaves, to avoid rot, pay attention to the spacing and density of planting.

Planting fruit trees needs to be fertilized scientifically according to local conditions, and different fertilizers should be eaten in different growth periods to supplement the required elements and prevent and control diseases. Hope it helps.

Of course I do. In fact, when planting, we must choose the right varieties, we must choose high-quality varieties, scientific fertilization, and scientific watering.

I have learned that the fertilization method for planting fruit trees is relatively simple, there will be a pattern every year, and there is a dosage, and you can't use too much.

1. Newly planted fruit trees, if they have been planted in the cultivation cup for a period of time in the early stage, are now transplanted. In most cases, a deep pit can be dug in the soil and a fertilizer rich in organic matter can be buried as a base fertilizer to provide the nutrients needed for the early growth of fruit trees.

2. Organic fertilizer is what we often call farmhouse fertilizer, which includes: human manure, manure, compost, plant ash, etc. When applying, add some compound fertilizer according to the proportion of application, which can be better absorbed by fruit trees.

3. If you miss the use of base fertilizer, you don't need to dig it up and apply it again. This can be done during this period if digging it out may cause the roots of the fruit tree to be destroyed in the new soil, and the fruit tree will die when it is already alive.

4. Don't be in a hurry to use fertilizer, do a good job of sun protection and watering. The amount of water should not be too much, it should be watered less at a time, watered many times, and kept the soil moist. After the new shoots have grown, top dressing is carried out.

5. When topdressing, about 50 cm away from the root system of the fruit tree, the annular or strip ditch, and then the organic fertilizer is infiltrated into the compound fertilizer and put into the application, and the soil is covered and watered after the fertilizer is applied. Remember that at the young age of fruit trees, the amount of fertilizer applied should not be too large. It should also be noted that the applied farm manure should be fermented and rotted.

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".

The correct fertilization of fruit trees is to evenly sprinkle fertilizer on the roots of fruit trees, because the roots are also the stomach of fruit trees, and scattered in this part can be well absorbed by fruit trees.

A simple survey of the growth of the fruit tree should be carried out to understand what kind of fertilizer the fruit tree needs before choosing the appropriate fertilizer to apply.

We must choose the fertilizer suitable for fruit trees to fertilize, and the dosage must be grasped each time, not too much and not too little, so that it is okay.

Timely watering and fertilization should be carried out, and phosphate and nitrogen fertilizers should also be chosen. At the same time, some compound fertilizers can also be added, and the soil should also be loosened in time.

Fertilization should be done on rainy days. In this way, the fertilizer can melt better.

Teach you the correct way to fertilize fruit trees, and the effect will increase several times.

The fertilizer required by jujube trees includes nitrogen, phosphorus and potassium, as well as medium and trace elements such as iron, zinc, calcium, magnesium and boron. Different fertilizers meet the needs of jujube trees at different growth stages, just as nitrogen mainly grows stems and leaves, phosphorus mainly grows roots, and potassium mainly bears fruits. Grapes do prefer potassium, but too much potassium before flowering can cause premature aging of the branches, especially in weakened trees, and fruit set and swelling are relatively poor.

The root system of fruit trees plays an important role in absorbing water and fertilizer. In order to make the root system absorb more fertilizer, some fruit farmers concentrate fertilizer near the root system, resulting in wilting and yellowing of fruit trees, which backfires. Abuse of fertilizer amounts:

At present, many fruit farmers still think that the more fertilizer, the better, and apply a large amount of chemical fertilizer, which not only can not achieve the effect of high yield, but may even cause fertilizer damage, reduce yield and lose harvest. Therefore, it is necessary to fertilize scientifically and rationally.

<> is very wrong, although they know that the fruit tree is not good without fertilizer, some fruit farmers want the tree to grow faster, so they apply a lot of manure, and add nitrogen fertilizer, the manure itself contains nitrogen and apply more nitrogen fertilizer, so don't apply more. That is, the fertilization is not scientific, non-standardized, and there is no professional agricultural technician to guide it. Fruit trees have different fertilizer needs depending on the growing season.

In terms of fruit tree growth and production, consult more professionals in agricultural technology. Ion adsorption in soil and uptake by roots. If the fertilizer fails to form ions, and the root system is not absorbed, it is useless to put more fertilizer, this process is similar to our people when eating some people absorb well, some people basically can't absorb, and many fertilizer dealers also have professional and technical personnel to explain the knowledge, these are not problems, but the quality of fertilizer is not ordinary people can know and master.

The same is to spend money to buy, but do not know which kind of fertilizer, once the flower is bought, the amount of fertilizer applied twice should account for 4o% of the annual fertilizer amount; The type of fertilizer should be high nitrogen, low phosphorus, low potassium and combined with medium and trace elements for hole application or sprinkling, and can also be used for flush fertilization; At the fruit expansion stage, high phosphorus, high potassium and medium and trace element compound fertilizer should be applied.

Fertilization from the tree far and deep to be suitable, can not encounter problems when you want to apply what you want, fertilization is not much good, according to their orchard soil and fruit tree actual situation, when it is August, just after the beginning of autumn, all kinds of fruit trees have reached the critical period of fertilization, scientific and reasonable fertilization methods, not only help fruit trees grow, but also can improve fruit quality, increase fruit yield.

1. The closer the fertilization point is to the tree, the better. Fertilization is far away from the tree, the root absorption is poor, and the nutrients can not be utilized, so the fertilization is very close to the tree, some are less than half a meter away from the root neck, and even dig out the backbone root, the result is that the phenomenon of hurting the root and burning the root often occurs, and this fertilization method has greater harm. 2. The more fertilizer you apply, the better.

Blindly think that the more fertilizer you apply, the better. The result is an imbalance between the supply and demand of nutrients in the tree, the heavy ones burn the roots and dead trees, and the diseases and insects breed, and the light ones have unbalanced vegetative growth and reproductive growth, only growing trees, and the fruits are less or even no fruits. 3. Fertilize according to the time.

Some fruit farmers do not fertilize according to the period when fruit trees need fertilizer, but according to the busy labor force to fertilize the spring fertilization into summer fertilization, should be fertilized in autumn into winter fertilization, should be applied before the flower fertilizer into the flower fertilizer, after the flower fertilizer into the fruit fertilizer, missed the best fertilizer period for fruit trees, the yield increase effect is greatly reduced. 4. Fertilize at will. Orchard autumn application of basal fertilizer is just in conflict with field autumn fertilization, many fruit farmers will use conventional chemical fertilizer instead of basal fertilizer, or use unrotted crop straw instead of manure and other farm fertilizer, year after year, the result is that orchard fertility declines, trees weaken, yield decreases, fruit quality deteriorates.

5. Unbalanced fertilization. Some users think that after applying compound fertilizer, there is no need to apply other fertilizers, which is wrong. General compound fertilizer generally only contains nitrogen, phosphorus, potassium elements, a small number of varieties contain zinc, boron elements, if you do not pay attention to timely supplement effective medium and micro nutrients and organic activated nutrition, it will also have a serious impact on crop quality, yield, income decline.
