Fruit tree fertilization methods, how to fertilize fruit trees correctly

1. Soil fertilization.

1. Ring fertilization.

It is also called wheel fertilization. It is to dig a ring ditch a little further away from the outer perimeter of the canopy to fertilize. This method has the advantages of convenient operation and economical fertilizer. However, it is easy to cut off horizontal roots, and the fertilization range is small, so it is generally used for young trees.

Pig trough fertilization: This method is similar to annular fertilization, and the ring is broken into 3-4 pig troughs. This method has fewer injured roots than annular application. Changing the fertilization position at intervals can expand the fertilization area.

2. Radial ditch fertilization.

This method hurts less roots than annular fertilization, but it also hurts less big roots when digging trenches, and the position of the radial ditch can be changed every other time to expand the fertilization surface and promote root absorption. However, there are also certain limitations to the fertilization site.

3. Fertilization of strips and furrows.

Fertilization is applied mechanically in orchard rows, interplant or interlaced rows, and can also be combined with deep soil ploughing.

4. Spread fertilizer throughout the garden.

This method is often used when the roots of adult fruit trees or densely planted orchards have been spread throughout the garden. Spread the fertilizer evenly throughout the garden and turn it into the soil. However, due to the shallow application, it often leads to the upfloat of the root system and reduces the stress resistance of the root system.

If this method is replaced every other year with radial ditch fertilization, it can learn from each other's strengths and weaknesses and give full play to the maximum effect of fertilizer.

5. Irrigation fertilization.

In recent years, irrigation fertilization has been widely researched, especially in combination with sprinkler irrigation and drip irrigation. Practice has proved that any form of irrigation fertilization, due to the timely supply of fertilizer, uniform distribution of fertilizer, not only does not hurt the root system, but also protects the soil structure of the cultivated layer, saves labor, and the fertilizer utilization rate is high, which can improve yield and quality, reduce costs and improve labor productivity.

Irrigated fertilization is more suitable for adult trees and densely planted orchards with adjacent tree canopies.

When to fertilize fruit trees? How to fertilize?

Make it simple, go to the countryside and look at natural fertilizers.

1.Top dressing during flowering. Fruit trees consume more nutrients from budding to flowering, if the nutrients stored in the previous year are insufficient, the nutrients are not timely, the flowering period will be extended and the fruit setting rate will be reduced.

Therefore, fast-acting fertilizer should be applied appropriately during the flowering period. If conditions permit, spray 250 times of borax aqueous solution again during the flowering period, which can greatly improve the fruit setting rate.

2.Top dressing after flowering. After flowering, young fruits and new shoots grow rapidly, and topdressing at this stage can make the new shoots grow robustly, expand the leaf area, improve the photosynthesis efficiency, and reduce physiological fruit drop. If the amount of fertilizer is large during the flowering period, the fertilizer can be applied less after flowering.

3.Top dressing before flower bud differentiation. At this stage, some new shoots have stopped growing, and the young fruits are rapidly expanding, so timely application of appropriate nitrogen, phosphorus and potassium fertilizers can enhance the photosynthetic effect of leaves, promote nutrient accumulation, and be conducive to flower bud differentiation and reduce the phenomenon of size and year.

4.Top dressing during the fruit growth period. Top dressing at this stage can not only increase the yield and improve the quality of the fruit in the current year, but also promote the differentiation of flower buds and make them full and full, and increase the later accumulation of nutrients in the tree.

When to fertilize fruit trees? How to fertilize?

Is it used to fertilize fruit trees before watering.

Urea nitrogen-containing diammonium said diammonium phosphate containing nitrogen and phosphorus, two nutrient elements, tree special fertilizer for trees should be produced by real factories, and the special fertilizer for market management fertilizer is used for apples.

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 fertilization method for fruit trees is as follows:

Soil fertilization is widely used before planting, especially when orchards are planted on a large scale. When the land of the orchard is leveled, fertilizer is applied near the planting site to ensure the nutrition of the initial fruit trees. The amount of fertilizer used in this method is high, but it is not easy to cause excess fertility of fruit trees in the early stage, so it is recommended to use farm manure in order to maximize the use of fertilizer.

Low, dense orchards can be fertilized in this way.

For some fruit trees with large fertilizer demand, soil burial fertilizer can provide a nutrient supply point for fruit trees for a long time, which is more suitable for some large varieties of fruit trees with relatively sparse planting area. It is recommended not to bury the root system directly, which is not conducive to the rooting and growth of the root system. The process is relatively simple, but it takes a lot of time, select the junction point of the nearby fruit trees, dig a soil pit, and bury the fertilizer.

Fruit tree introduction

The nutritional and health function of fruits is rich in nutrients, including a variety of vitamins and inorganic salts, sugar, starch, protein, fat, organic acids, aromatic substances, etc., which are necessary for human growth and nutrition. According to nutritionists, each person needs 70 80kg of fruit per year to meet the normal needs of the human body. The medical function of fruitsMany fruits and seeds can be used in medicine, which has the best effect.

Ecological and environmental benefits of fruit trees Fruit trees are generally adaptable, not only can be planted in plains, rivers on both banks, roads, rural gardens and behind the house, but also can grow in sand, hills, tidal flats and other places, select and plant suitable fruit trees, not only increase economic income, but also prevent soil erosion, increase green coverage area, regulate the climate, so as to green, beautify and purify the environment.

1. Building a park 1. Park selection. In the shallow hilly area with convenient transportation, convenient drainage and irrigation, deep soil layer, low groundwater level and no air pollution.

2. Select excellent varieties and high-quality strong seedlings and fruit trees without quarantine pests and diseases for 1 2 years.

2. Fruit tree cultivation.

1. Dig holes at fixed points.

2. Planting density.

4. The fixed value is 8:1 or 6:1 to configure the pollination tree. When planting, the roots should be straight, the lower step should be tight, the upper surface should be loose, the saplings should be taken as the center, and the water should be piled into a water disc, and the roots should be fixed with enough manure water.

5. Fruit tree cover.

3. Kindergarten intercropping.

Within 1 or 2 years of planting fruit trees, when the rows are not closed, crops can be planted intercrops, making full use of land data, and growing in a short time.

Fourth, fruit tree plastic pruning.

1. Pruning and shaping of juvenile fruit trees. At present, dwarf and high-yield cultivation technology is used in production, and young fruit trees focus on cultivating tree shape. The evergreen fruit trees were thinned to achieve the cultivation type, so that the fruit trees were ventilated and transmitted, and the branches were evenly distributed. It is often used in the production of deciduous fruit trees such as peaches, plums, pears, etc"y"Font and cup-shaped tree type, pear pears are poured"people"Shape the glyph or double fence shaping.

2. Pruning and shaping of adult fruit trees. Prune after fruit picking, and use fruit shears to cut off diseased branches, stump branches, dead branches, and weak branches. Winter pruning: Deciduous fruit trees go dormant and begin fruit tree pruning. Pruning of evergreen fruit trees is carried out before the spring shoots are extracted, when the old leaves will fall off at most.

5. Orchard fertilizer and water management.

1. Apply basal fertilizer. Fruit trees are often fertilized immediately after fruit picking, and basal fertiliser is applied before fruit picking for high-yielding or late-maturing varieties.

2. Fruit tree covering. Combined with fertilization, cover the fruit tree tray with 5 10 cm thick straw; For fruit trees with poor light transmittance, the fruit coloring requirements are higher, and the tree tray can be covered with silver reflective film.

3. Top dressing and irrigation. Depending on the amount of fruit set, tree vigor and the amount of fertilizer applied in winter, top dressing can be done during the critical period of fruit tree growth.

6. Flower and fruit management.

1. Thin vegetables and fruits. Artificial flower thinning and fruit thinning can start from double cutting before flowering to adjust the amount of flower buds, and after flowering, vegetable thinning and young fruit thinning can be carried out. Fruit thinning should be carried out as early as possible after the first physiological implementation of young fruits.

According to the amount of fruit hanging per plant, the weak fruits in the inflorescence were thinned, and the tip fruits, weak branch fruits, small fruits, diseased fruits, insect fruits and deformed fruits were thinned to retain the strong fruits.

2. Fruit bagging: use all wood pulp double-layer bags, carry out as soon as possible after setting the fruit, and spray an insecticide and fungicide, complete the bagging work within 15 days, and remove the bagging about 30 days before the fruit is harvested.

Top 10 Methods of Fertilizing Fruit Trees

1. Annular ditch fertilization method.

A circular trench 30 to 40 cm wide and 15 to 45 cm deep is dug around the canopy and a mixture of topsoil and basal fertilizer is applied. This method is suitable for young orchards.

2. Radial fertilization method.

1 m away from the trunk, dig 6 to 8 radial trenches, 30 to 60 cm wide and 15 to 45 cm deep, reaching the outer edge of the trunk. Cover the soil after fertilizing the ditch. This method is suitable for mature orchards.

3. Fertilization method of strip ditch.

Between fruit trees or between plants, dig 1 to 2 long trenches 50 cm wide and 40 to 50 cm deep, then fertilize and cover the soil. This method is suitable for mature orchards.

4. Acupuncture spelling.

Under a tree with a diameter of 1 meter, 10 to 20 conical points with a depth of 40 to 50 cm, an upper mouth of 30 cm, and a bottom of 10 cm are evenly excavated. The acupuncture points are filled with dead branches and rotten leaves, covered with plastic sheeting, and top dressing and watering are all within the acupuncture points. This method is suitable for sandy orchards with poor water and fertility retention.

5. Soil drilling and fertilization method.

Use a drill bit to drill under the canopy of the tree and pour the diluted fertilizer into the hole so that the fertilizer water can slowly penetrate. This method is suitable for orchards in densely planted areas and mature orchards in arid areas.

6. Whole garden fertilization method.

Spread the fertilizer evenly throughout the garden and turn the fertilizer into the soil to a depth of 25 cm. This method is suitable for mature trees with full roots or densely planted orchards.

7. Fertilizer method with water.

Mulching young trees can first dissolve the fertilizer in the water god reed, and then apply it together with the irrigation water.

8. Intercropping fertilization method.

Intercropping red vetch, peas, yellow flowers, alfalfa, broad beans, mung beans, soybeans, etc., can improve soil organic matter. This method has a good effect on both kindergarten and adult kindergarten.

9. Extra-root (foliar) fertilization.

If it is found that the fruit tree has mild nutritional disorder symptoms, the method of spraying liquid fertilizer can be used, and the concentration of spraying liquid fertilizer can be determined according to the tree species, tree age, growth period and fertilizer type, and the general continuous spraying is 2 3 times, with an interval of 7 10 days each time.

10. Trunk drilling and fertilization method.

Three deep holes are drilled at the base of the trunk, and the fertilizer liquid required by the fruit tree is directly injected into the tree body with a high-pressure injection machine, which is suitable for the application of medicinal fertilizer and the correction of iron deficiency in fruit trees.

In the planting and management of fruit trees, there has always been "fertilization of fruit trees."

Three, six, nine" said, that is, our fruit farmers usually say, do spring fertilization, summer fertilization, autumn fertilization, spring fruit tree fertilization time is generally in early March - mid-April, the best time for fruit tree fertilization this summer is from mid-June to early July, the best time for autumn fruit tree fertilization is generally in early September to the end of October, these three fertilization periods not only correspond to the "three, six, nine" on the fertilization of fruit trees in turn, and these three fertilization periods also correspond to the spring root growth of fruit trees. In addition, in addition, the main purpose of fertilization in March of spring is to preserve flowers and fruits (to promote budding and leaf development and flowering and fruit setting), the main purpose of fertilization in June in summer is to promote fruit expansion in oranges (to promote flower bud differentiation and young fruit expansion), and the main purpose of fertilization in autumn and September is to promote root growth and tree growth (to promote root growth and tree growth).

Today's agricultural technology basket will briefly tell you about the time, type, and method of "369" fertilization of fruit trees, as well as the relationship between the root system of fruit dust trees and three fertilizations.

1. Spring fertilization of fruit trees - promote shoots, promote flowers and fruits.

Spring fertilization of fruit trees is the key period for the tree to reserve nutrients, the best time for fertilization is before the budding of the fruit tree to before flowering (about 3-4 months), during this period, the nutrients accumulated in the autumn of the year are basically exhausted, and it is urgent to increase and reserve the nutrients of the tree body by fertilization, so as to accumulate sufficient nutrients for the next budding, leaf development, flowering, fruit setting and the rapid growth of spring and spring roots. If the fertilization is insufficient during this period, it will not only inhibit the normal growth of new shoots, new leaves, new roots and new roots of the fruit tree, but also have a very adverse impact on the subsequent smooth flowering and fruiting of the fruit tree.

Fruit trees with correct types, proper methods and reasonable dosages in spring will generally have the significant advantages of rapid growth, hypertrophic leaves, strong branches, developed root systems, early flowering and high fruit setting rate. All fruit trees that are not fertilized in spring are mostly slow to grow and thin, poor flowering and fruit setting and poor quality, low flowering and fruit setting rate, large amount of flower and fruit drop, and low flower and fruit retention rate.

Through our introduction, I believe you have a deeper understanding of the fertilization method of potted fruit trees.
