Fruit trees take root very slowly and do not grow well, what is the reason for this?

The base fertilizer should be mainly well-rotted organic fertilizer or biological fertilizer, followed by a reasonable ratio of nitrogen, phosphorus and potassium fertilizer use, autumn fertilizer less nitrogen fertilizer, increase the use of phosphorus and potassium fertilizer, after germination to apply a certain amount of nitrogen fertilizer, but also do not use excessively, so as not to cause excessive vegetative growth and affect the accumulation of vegetative growth. Some informal nurseries are negligent in management or cost savings, and do not sterilize the soil, causing apple seedlings to be infected with rhizobia, and the seedlings grow unsatisfactory after transplanting without the knowledge of fruit farmers. Therefore, the safe selection of seedlings to avoid being greedy and cheap into the routine, the regular nursery garden is assured.

<> this situation, you can choose the "two-liquid method" promoted by the modern fruit industry to irrigate the roots, which can make the apple trees prosperous that year. First add 500 catties of water to the root sap and then add the root cleaning solution and stir well, then dig radial pits around the apple trees, and feed 50-100 catties per tree. Cover again.

If you want to make the apple tree grow well, you must pay attention to the selection and application of fertilizer, the base fertilizer can choose Dikangbao microbial organic fertilizer, and the top dressing can choose Dikangbao as microbial fertilizer, the two can be used together, which can supplement the nutrients needed for apples, promote growth, increase production and income.

It has the ability to promote the flowering of fruit trees and induce the development of parthenocarp. However, not all fruit trees can be used for slow growth, there are also soaked flowers and roots, and most fruit trees are still used to speed up their rooting. Different fruit tree seedlings are also used in different ways.

In order to grow fruit trees well and grow vigorously, it is recommended that the subject strengthen the fine management of fruit trees from many aspects such as base fertilizer, water management, pest and disease control, and then supplement it with plant growth regulation, only in this way can the subject's fruit trees grow healthily and strongly. There are two large growth periods for apples, in these two periods to have enough carbohydrate supply, first put the roots and leaves according to about 500 catties of water, add plus the root cleaning liquid and stir evenly, dig inclined pits around the apples, water about 20 catties per tree and then cover. The slow growth of fruit trees is caused by many reasons, such as soil acidification, fertilizer application, insufficient fertility, lack of elements, fertilizer effect can not be diluted and dissolved into the soil for root absorption, nourishment for tree growth, and so on.

In fact, the main reason for not growing well is that he does not have enough watering time, and then the fertilization process is not right, so it will cause such a phenomenon.

That is the problem of bad geographical location, if the geographical location is good, it can be said that there is a lot of nutrition, and it will grow well.

It is likely that the fruit tree lacks nutrients and water, and it is only necessary to give him enough nutrients and water in time.

Slow germination of fruit trees may be due to one of the following reasons:

Ambient temperature is too low or too high: The suitable temperature range for growing fruit trees is 16°C to 24°C, if the temperature is too low or too high, it will inhibit the germination rate of fruit trees.

Poor soil conditions: Soil conditions have a great impact on the survival and growth of fruit trees. If the soil quality is not good, too much or too little water, lack of nutrients, etc., it will affect the germination rate of fruit trees.

Lack of light: Fruit trees need adequate light for photosynthesis and the production of nutrients. If the fruit tree grows in a lack of light, it will affect the germination rate of the fruit tree.

Pest and disease attack: Fruit trees are attacked by viruses, bacteria, fungi, insects and other pests, which will affect the germination rate of fruit trees.

Different varieties: Different species of fruit trees have different germination rates, and some fruit tree species have a slower germination rate, which requires patience.

Therefore, if the germination of fruit trees is slow, it is necessary to check the growth environment, soil quality and nutrient deficiency conditions, and take corresponding measures in time to adjust the growth environment of fruit trees to improve the germination rate of fruit trees.

There may be several reasons why fruit trees germinate slowly:

1.Lack of water: Lack of water is one of the common causes of slow germination of fruit trees. If the water table is lowered, the water source to the roots of the tree is cut off, or if there is dry weather, the growth of the fruit tree is affected, resulting in slow bud germination.

2.Nitrogen, phosphorus, potassium deficiency: These elements are essential nutrients for the growth of fruit trees, and if the soil is deficient in these elements, it can affect the germination and growth of fruit trees.

3.Low temperature: Fruit tree flowering, fruiting and sprout production are all related to the temperature of the forest. If the temperature is too low, it may affect the germination rate of the fruit tree.

4.Pests and diseases: If fruit trees are attacked by pests and diseases, they tend to grow slowly and even die.

5.Poor soil quality: Fruit trees need loose, nutrient-rich soil to grow well, and poor soil quality, or if the soil is dense and impermeable, it may cause the fruit tree to germinate slowly.

If the fruit tree germinates slowly, it is necessary to take measures according to different reasons, such as increasing the amount of watering or fertilizing, adjusting the temperature, preventing pests and diseases, and trimming the branches, so as to help the fruit tree resume growth.

Temperatures that are too low or too high can affect the germination of fruit trees. Fruit trees usually need to grow between 15-25 degrees Celsius. 2.

Insufficient soil nutrients: If the soil is not rich in nutrients, fruit trees may sprout slowly or grow stunted. 3.

Lack of light: Fruit trees often need plenty of sunlight to grow properly, and if there is not enough light, it will lead to slow germination. 4.

Pest and disease attack: When fruit trees are attacked by viruses, fungi or insects, they are also prone to slow germination. 5.

Lack of water: Fruit trees need sufficient water to grow smoothly, and if they do not have enough water, it may affect the germination process. If the germination of the fruit tree is slow, you can combine the above reasons to investigate one by one, find out the problem and make corresponding adjustments to promote the healthy growth of the fruit tree.

In order to make the root system of fruit trees developed, on the one hand, there must be relatively fertile soil, on the other hand, fruits and vegetables should be watered regularly to ensure sufficient water, and fertilizer should also be guaranteed in time.

The root system of fruit trees is developed, and the soil should be properly loosened and nitrogen fertilizer should be drawn. Water moderately at regular intervals. In addition, chicken manure, or quail manure should not be too close to the roots.

When the new orchard is established, it is necessary to choose a plot with flat terrain, deep soil layer, fertile soil, high organic matter content, leeward and sunny and convenient drainage and irrigation, and not to plant fruit trees in places with heavy stickiness, serious saline-alkali compaction, weak soil, poor soil, water and fertilizer leakage, and poor drainage and irrigation conditions.

Pay attention to the use of organic fertilizer in rural areas to transform soil quality.

The fruit trees are not pruned well, the wind permeability of the fruit trees is relatively poor, and the air permeability of the soil is relatively poor, so there is no fruit. Find a more professional pruner to prune the fruit trees and prune off some useless branches.

I think it is not well controlled, the early stage is the time of semi-fertilizer, and the later stage of the application of high potassium fertilizer is the original Li Grip rule; It is necessary to adjust the ratio between nitrogen, phosphorus and potassium, appropriately increase the ratio of phosphorus and potassium fertilizer, and prune fruit trees that are too heavy, and adjust the tree shape in a targeted manner.

In the process of caring for fruit trees, topping should be carried out reasonably, which can ensure that the crown of the fruit tree grows well and can also improve the fruiting rate of the fruit tree.

What should I do if the fruit tree grows more and more vigorously, but it just doesn't bear fruit? The old farmer teaches you three ways.

The fruit tree grows more and more vigorously but does not bear fruit, it may be that we have not eliminated one of its apex advantages, the nutrients are sucked away by the top branches, at this time we can prune the top branches, and those excess branches can also be pruned.

Through pruning operations, the over-vigorous branches and weak branches can be reasonably pruned and pruned, and the flowering rate can be improved by retaining mediocre branches. Reduce the application of nitrogen fertilizer, reapply phosphorus fertilizer, and supplement potassium fertilizer.

It needs to be pruned to cut off the twigs that don't catch the fruit. Also prune the small branches that have a lot of forks on them. Finally, cut off the branches that grow too tall and can't reach, and that's it.

According to the characteristics of weather changes, do a good job of controlling the shoots of fruit trees to promote shoots, and for over-prosperous trees, you can only put the fruiting mother autumn shoots. Through pruning operations, the over-vigorous branches and weak branches should be reasonably pruned and pruned, and the flowering rate of mediocre branches should be retained. Too much thinning, too much thinning is also a sign of over-pruning, mainly caused by over-forcing the shape of the tree.

Some fruit growers even leave only a few backbone branches, which not only affects the growth of the tree, but also seriously affects the early fruiting and early yield.

<> purpose of circumcision is to prevent excessive water and nutrients from being transported to the end of the branch group and promote the differentiation of flower buds. Circumcision of the main and lateral branches 1-2 turns, the depth is the junction of the phloem and the xylem, and the xylem must not be injured. Judging from the growing and vigorous fruit trees, there is a problem of excess nutrients in fruit trees.

In the process of fertilization, excessive application of nitrogen fertilizer will show the phenomenon of overgrowth of branches and leaves, and the growth of branches and leaves will inhibit the reproductive growth of fruit trees.

Unreasonable fertilization and water application is the main reason for the vigorous growth of fruit trees, after all, sufficient nutrient water is the premise of vigorous growth of fruit trees, which is mainly the excessive application of nitrogen fertilizer, which causes strong nitrogen metabolism of fruit trees to grow vigorously in summer, and the trees should be on the back and lower branches in time, so that the large branches can be extended uniaxically, and the tree type can be used to remove useless branches, so that the tree can be controlled, so that the tree can be transformed from vegetative growth to reproductive growth.

There is no pulling or no effective pulling of branches. The best time to pull branches for young apple trees is around May in the spring, one year after transplanting, when the branches of the apple trees are at their softest and easiest to pullFor the phenomenon that fruit trees grow more vigorously and do not bear fruit, we must carry out reasonable management and take a variety of measures to promote flowering and fruiting. The worst thing is a large number of thinning and pruning, which will be more vigorous and difficult to produce flowers and fruits.

If it is flowering does not bear fruit,It shows that the two major elements of nitrogen and phosphorus are sufficient, and there is even a possibility of excess. In response to this situation, the proportion of the three elements should be adjusted to reduce the amount of nitrogen fertilizer in the past.

Because this fruit tree does not bear fruit in that season, because the temperature and soil moisture are very related, so it will not bear fruit.

Many fruit trees only bloom and do not bear fruit because of pollination, normal flowering indicates that the fruit tree is about to enter the fruit setting stage, at this time we must do a good job of pollination, we need to fully understand the pollination mechanism of our own fruit trees.

This is the plant has grown, must be sprayed in time to control the growth rate of the fruit village, only this can make it bloom and bear fruit as soon as possible, usually before the fruit tree enters the flowering period to control water and fertilizer, so as to avoid the growth of fruit trees.

The root system of fruit trees is not long, and it is very likely that there is something wrong with the root system.

The growth of the root system peaks several times a year, and the occurrence of the peak is usually staggered with the peak of aboveground growth. More than 50% of the photosynthetic products of fruit trees are used for root growth, and organic nutrients (including stored nutrients) are insufficient, which is not conducive to root growth. Flowering and fruit setting and fruit growth and development consume a lot, which is not conducive to root growth. The vegetative growth of the aboveground part is vigorous, which is not conducive to the growth of the root system.

The root system of fruit trees starts to move earlier than the aboveground part and stops later. In the northern fruit tree cultivation area, the root system of mature trees has three peak growth periods in a year:

1. When the soil temperature reaches 7 8 or more in spring, the root system begins to grow. Generally, from pre-bud to late April, there is a peak of growth, which is mainly restricted by ground temperature and nutrient storage. This peak has more roots, but the growth time is shorter.

2. From the beginning when the new shoots are close to stopping growth, there is a secondary growth peak (from the end of June to the beginning of July) before the accelerated growth of the fruit and the differentiation of flower buds. At this time, due to the many leaves, strong assimilation ability, and many nutrients, the water, fertilizer, gas, carbon, oxygen, and thermal conditions required for root growth are better, which can promote the growth of the root system, and the growth time is long, and it is the period of more roots throughout the year.

From the beginning of the month to the end of November, as the foundation for flower bud differentiation has been laid, the fruits have been harvested, the nutrients produced by the leaves have returned and accumulated, and the nutrients obtained by the roots have increased, and there are three growth peaks. This peak lasted for a long time, but the growth was weak. This period is the period of chasing the Svoreugenlef, and generally the earlier the absorption, the better.

Therefore, the autumn management measures are deep ploughing and application of organic fertilizer to promote the occurrence of growing roots.
