How to fertilize pomegranate trees well? What is the best fertilizer to apply to pomegranate trees

The pomegranate tree is also an ornamental tree, and it can also be sprinkled with some compound fertilizer when it blooms and bears fruit, and it is also fertilized according to the growth of the pomegranate tree and the woods when it is sprinkled. In particular, some weak trees should eat more fertilizer, and use some boron fertilizer to top dressing the roots of pomegranate trees before flowering.

Fertilization begins one month after planting. The concentration of fertilizer should not be too high. It is best to use nitrogen and potassium fertilizers. Fertilize also a week before flowering. The rest of the time is fertilized once every half a month.

1) Spring: Spring is an important period for the growth of pomegranate trees, with vegetative growth as the main body. Therefore, when fertilizing, nitrogen fertilizer is the main fertilizer. Fertilization should be applied as early as possible, and it is best to apply it at the time of germination.

2) Summer: This is an important stage for pomegranate flowering, fruit setting, fruit development and flower bud differentiation, and the important thing is fruit set. In the application of nitrogen fertilizer, it should be determined according to the tree, flexibly mastered, strong trees are not applied, moderate trees are appropriately applied, and weak trees are more applied.

For mediocre trees, the dosage ratio of nitrogen, phosphorus and potassium should be controlled. Apply before the first flowering period if possible. In order to improve fruit set, boron fertilization was applied outside the roots during the flowering period.

After flowering, nitrogen, phosphorus and potassium fertilizers should be applied to old and weak trees to promote the recovery of tree strength.

3) Autumn: Autumn fruit is close to ripe, flower bud differentiation is still continuing, the tree consumes a lot of nutrients, at this time fertilization is the most important fertilization of the year, mainly to apply organic fertilizer, to turn the soil. The amount of organic fertilizer accounts for about 70%-80% of the total amount of fertilizer applied throughout the year.

Top dressing was carried out outside the roots before harvest to promote fruit expansion, increase the color of the peel and the sugar content of the fruit.

Pomegranate tree pruning and fertilizing, do you know all the skills? Check it out and make no mistake.

Pomegranate trees should be fertilized with nitrogen and phosphorus fertilizers.

1. Spring fertilization: The time of spring fertilization of pomegranates is before germination and after flowering. Spring is the main growth and development time of new organs of pomegranate, so nitrogen fertilizer is mainly used in terms of fertilizer.

In the early stage of growth, in order to ensure that the pomegranate tree can continue to absorb nutrients, spring fertilization should be as early as possible, and fertilization at the germination stage is the best. In terms of fertilizer, Bika high nitrogen water-soluble fertilizer is the main fertilizer.

2. Summer base fertilizer: The fertilization time of summer base fertilizer is generally better in May. At this point, the leaves largely stop growing, but the growth of the fruit and root system continues.

Organic fertilizer is the main fertilizer on the fertilizer seed, and the fertilization will not cause the second growth of pomegranate and affect the accumulation of nutrients in the fruit, which is conducive to the absorption of the root system.

1. The organic fertilizer commonly used in pomegranate trees is also called base fertilizer, including all kinds of compost, circle fertilizer, human manure, poultry manure, cake fertilizer, litter, turf, urban garbage and green manure, among which most of them are delay-acting fertilizers except for well-rotted human manure. 2. Inorganic fertilizers commonly used in pomegranate trees Inorganic fertilizers are also called fast-acting fertilizers or mineral fertilizers, including various chemical fertilizers, mineral powders, plant ash, etc. Inorganic fertilizer has the advantages of fast fertilizer efficiency, high fertilizer efficiency and easy absorption.

However, there are shortcomings of improper fertilization, which are prone to fertilizer damage and short duration of fertilizer effect, easy to leach, and long-term single application makes the soil compact. The nitrogen fertilizers commonly used in pomegranate orchards mainly include urea, bicarbonate, sulfuric acid, ammonia, etc. Commonly used phosphate fertilizers mainly include superphosphate, heavy superphosphate, bone meal, phosphate rock powder, etc.

Commonly used potash fertilizers are potassium sulfate, potassium chloride, and potassium carbonate (plant ash). Trace element fertilizers mainly include borax, boric acid, amino acid calcium, zinc sulfate, etc.

The fertilizers commonly used in pomegranate trees can be broadly divided into two categories, namely organic fertilizers and inorganic fertilizers.

Organic fertilizer is a general term for fertilizers that contain organic fertilizers. Including human manure, cattle manure, sheep manure, pig manure, chicken manure, etc. Organic fertilizer is a complete fertilizer, which not only contains a variety of nutrients required for plant growth, but also contains rich organic matter, which can stably supply the nutrient needs of tree growth and development for a long time (Table 7-3), and can effectively improve the soil.

In pomegranate orchards, organic fertilizer is mostly used as a base fertilizer in autumn.

Inorganic fertilizers are chemical fertilizers. Generally, fast-available nitrogen fertilizer should be applied in early to mid-May before flowering, combined with phosphate fertilizer, to promote vegetative growth. N, P and K compound fertilizers were applied at the fruiting stage after flowering and the expansion stage of young fruits to promote the rapid growth of young fruits and the formation of flower buds.

At the same time, during the growing season, topdressing should be carried out several times outside the roots, and the leaves should be sprayed with urea or 1% diammonium phosphate. When micronutrient deficiency is shown, micro-fertilizer should be sprayed in time. In summer, according to the time when the general fast-acting fertilizer is absorbed and utilized by crops (7 to 10 days), it should be applied before the first flowering period as much as possible; Boron fertilizer can be topdressed outside the roots at the flowering stage to improve fruit setting power.

After flowering, nitrogen, phosphorus and potassium fertilizers should be applied to the old and weak trees, and comprehensive adjustment should be carried out in conjunction with thinning flowers and fruits, so as to promote the recovery of tree potential. In poor soil conditions such as sandy and gravel, it should be applied diligently and sparingly. The significance of summer fertilization is very significant, one is to ensure flowering and fruit set; the second is for the development of young fruits; The third is to lay a good foundation for the differentiation of flower buds in the later stage of this period. In the fertilization method, a soil top dressing is the main one, and root top dressing can also be used.

Fertilizer varieties, ammonium bicarbonate, ammonium sulfate, urea, etc. for nitrogen fertilizer; superphosphate for phosphate fertilizers; Potassium fertilizer uses potassium sulfate or plant ash, and compound fertilizer diammonium phosphate, potassium dihydrogen phosphate, etc.

1. The main reason for the yellowing of the leaves of potted pomegranate trees is that the leaves are yellowed due to excessive watering, hard potting soil boards, and too dark ones.

1. The phenomenon of yellow leaves of pomegranate flowers caused by excessive watering is not easy to be too wet when watering, and the overly wet soil is easy to accumulate water and produce root rot and yellow leaves. It is best to keep the soil dry and watered, so that it is not dry and watered, so that it is conducive to the growth of the root system, so that it is not easy to appear yellow leaves.

In the autumn (September to October), pomegranate trees should apply organic fertilizers such as sheep pen manure, rabbit manure, circle fertilizer, manure, biogas residue, human manure and urine, and add an appropriate amount of potassium sulfate compound fertilizer. It is applied in a ring-shaped furrow at the projection of the outer part of the canopy, the depth of the furrow is about 60 cm, and the amount of fertilizer is determined according to the size of the tree.

Pomegranate trees, should be applied with organic fertilizer to ensure product quality, increase yield, and protect fruits, with organic fertilizer as the main compound fertilizer to achieve sweetening and fruit, improve quality and increase yield, so that their own pomegranates can achieve high-quality commercial fruits.

Answer]: 1. Top dressing during the growth period.

It is mainly applied 3 times before flowering, during the growth period of young fruits and during the period of fruit expansion and veraison. Pre-flowering fertilizer: 20-30 kg of manure + kg of urea per plant in 2-3 months before flowering. Subsequently, in the growth period of young fruits in May, kilograms of compound fertilizer were applied to each plant.

When the fruit is swelling and veraison, the peel begins to change color, and each plant is applied with a kilogram of compound fertilizer. Observe the tree potential, so that the branches and leaves do not turn yellow, and the plants that do not appear to be defertilized can be carried out with normal fertilizer application; If there are many fruits, yellowing leaves, and plants with lack of fertilizer, it is necessary to increase the amount of fertilizer and add a small amount of urea. Adequate irrigation must be done after fertilization.

2. Top dressing outside the roots.

From July to August, when the fruit is enlarged and veraison, phosphorus and potassium fertilizer can be added, and potassium dihydrogen phosphate urea mixture can be sprayed outside the root, once every 10 days, 2-3 times in a row.

3. Fruit picking fertilizer.

It is better to apply the base fertilizer in early November to early December. Otherwise, too early fertilization will delay the growth of the shoots, and the branches will not be full, reducing the proportion of "first flower" and "simple flower" in the following year. The base fertilizer is mainly organic fertilizer, and 1500-2000 kg of organic fertilizer such as circle fertilizer (farmhouse fertilizer) and compost are applied per mu, and the annular ditch is used to apply deeply, so as to facilitate "deep rooting".

The method is to dig a ring ditch (or semi-ring ditch) with a depth of 30 cm and a width of 20 cm at the drip line of the canopy, and apply the prepared farm fertilizer in the ditch, each plant is applied with 20-30 kg of farm fertilizer, 2 kg of compound fertilizer, 1 kg of superphosphate, and then fully irrigated. After that, the hole was expanded outward and the soil was turned deep and renovated year by year, and it was rotated in different directions every year.

Pomegranate trees can be planted 15-20 days before the application of fully rotted farm fertilizer, during the growth period can be applied potassium sulfate compound fertilizer, or at the leaves can be sprayed potassium dihydrogen phosphate, to promote flowering and fruiting, fertilization must pay attention to the dosage, to avoid rotten roots, especially not to overapply nitrogen fertilizer, so as not to grow wildly, but also reduce the fruiting rate of pomegranate trees.

Pomegranate tree fertilization time.

Pomegranate trees can be fertilized during the growth period, mainly from May to October, with a compound fertilizer with higher phosphorus and potassium content in May, and a compound fertilizer with higher nitrogen and potassium content from August to September.

What fertilizer to apply to pomegranate trees is suitable for banquets.

1. Potassium sulfate Fugao Cave Hefei

Pomegranate can be applied potassium sulfate compound fertilizer, which is rich in phosphorus and potassium elements, which can promote its better growth, and have sufficient nutrients for it to flower and fruit, but pay attention to the fertilizer to be diluted, not to apply concentrated fertilizer.

2. Potassium dihydrogen phosphate

The leaves of pomegranate can be sprayed with potassium dihydrogen phosphate, mainly because potassium is abundant, which can provide sufficient nutrients for the leaves and promote its flourishing, so as not to dry up and yellow due to insufficient nutrients, affecting its normal growth.

3. Farm fertilizer

When pomegranate is planted, you can apply farmhouse fertilizer in the soil, which can promote the better growth of its roots, so that the pomegranate tree can become vigorous and strong, and when applying farmhouse fertilizer, you can also add available nitrogen, which contains nitrogen, phosphorus and potassium fertilizer.

Pomegranate tree fertilization method.

Pomegranate trees can be planted 15-20 days before the application of fully decomposed farm fertilizer to meet the demand for nutrients during the growth period, during the growth period to apply nitrogen, phosphorus and potassium fertilizer, to promote the growth of the plant, can be applied before the flowering period of phosphorus and potassium fertilizer, Qi Xiang withered to promote the differentiation of flower buds.

Pomegranate tree fertilization also needs to be based on the season, spring and summer is the season of its vigorous growth, need to apply thin fertilizer frequently, but can not be fertilized at noon when the temperature is high in summer, so as not to cause fertilizer damage, and the summer temperature is very high, you can reduce the fertilization in moderation, winter is its dormant period, can stop fertilization.

Pay attention to the fertilization of pomegranate trees.

When fertilizing pomegranate trees, we must pay attention to the dosage to avoid root rot, especially not to overapply nitrogen fertilizer, so as not to grow wildly on branches and leaves, and also reduce the fruiting rate of pomegranate trees.

It is good to apply organic and inorganic fertilizers to pomegranate trees.

1. Organic fertilizer

Organic fertilizer is used as a base fertilizer, and fertilizer mainly includes compost, circle fertilizer, human manure, poultry manure, cake fertilizer, green manure, etc. The nutrients of organic fertilizer are relatively comprehensive and lasts for a long time, which can improve the soil environment and promote the growth of pomegranate trees.

2. Inorganic fertilizers

Inorganic fertilizers are also called fast-acting fertilizers or mineral fertilizers, specifically chemical fertilizers, mineral powders, plant ash, etc. The application of inorganic fertilizers during the growing season can meet the nutrient needs of the pomegranate tree and help the pomegranate tree to bloom and bear fruit.

Fertilization method of pomegranate trees

1. Strip fertilization method

At the outer edge of the pomegranate canopy, dig two fertilization furrows with a width of 50-60 cm and a depth of 30-40 cm, the length of which depends on the size of the canopy. After the ditch is dug, the farmer's manure or organic fertilizer and the top cooked soil are mixed into the ditch, and then the core soil is covered in the ditch soil and tree tray.

2. Ring fertilization method

A circular ditch about 50 cm wide and 25-40 cm deep is dug around the vertical projection of the canopy, and the fertilizer is mixed with the topsoil and applied to the overlying soil. This method is mostly used for young trees.

3. Spread the spell throughout the garden

The fertilizer is first spread evenly in the garden, and then turned into the soil with a machine to a depth of 20 cm. Generally, adult pomegranate trees or pomegranate trees are densely planted in high-yield gardens, and this method is mostly used when the root system is spread throughout the garden.
