What kind of fertilizer does jujube trees need at different stages?

After flower bud differentiation, nitrogen, phosphorus and potassium mixed fertilizers were the main fertilizers, which were beneficial to fruit development and root growth, and could improve fruit quality. In order to improve the fruit setting rate, 300 times sodium borate and zinc sulfate can be sprayed at the flowering stage, which can effectively improve the fruit setting rate. In addition, jujube trees have a large number of flowers, low fruit setting rate, and serious flower and fruit fall, which is also a critical period for pest control.

Therefore, strengthen.

The management of jujube orchards in May and June has a great impact on the annual output. The main tasks in this period are soil fertilizer and water management, improving fruit setting rate, summer pruning, and pest control.

Organic fertilizer: It can increase the nutrients of plants, store more nutrients in the fruit, and also convert starch into soluble sugar, making the taste more and the quality improved. Therefore, the application of organic fertilizer is one of the important reasons why the harvested dates are sweet or not.

Top dressing at the young fruit stage not only directly affects the yield, but also relates to the quality of the fruit. Foliar fertilization. It is also called root topdressing.

Trace elements have a certain effect on the fruit rate and yield of jujube trees, especially the boron effect is better. Boron spraying can not only promote early flowering, pollination and seed setting of jujube trees; Moreover, it can overcome the adverse effects of rainy weather on flowers, achieve the purpose of preserving flowers and fruits, and improving fruit setting rate.

Applying 1 kg of urea or 1 kg of compound fertilizer at the end of flowering can significantly increase the yield. The method is to dig a deep and 40 cm wide annular ditch 2 meters away from the trunk, sprinkle the fertilizer in, fill it with enough water, and fill the ditch after the water seeps out.

The amount of fertilizer applied depends on the size of the jujube tree, the type of fertilizer, the soil fertility and the amount of fruit. For large trees in the peak fruiting period, more fertilizer should be applied, more fruits, lower soil fertility, poor fertilizer quality, etc., more fertilizer should be applied appropriately. On the contrary, fertilizer can be applied sparingly.

No matter what kind of fertilizer is chased, the distance of top dressing should be determined according to the length of the root system, otherwise it is easy to cause fertilizer damage. Regardless of the kind of fertilizer, it is necessary to backfill and water in time after chasing. This facilitates the absorption of fertilizers.

During the flowering period, it is necessary to supplement the nutrition of the tree in time, which can not only improve the fruit setting rate, but also be conducive to the growth and development of the fruit. Top dressing at the flowering stage is mostly used to spray urea on the foliar surface. Before germination, top dressing is particularly important, which can not only promote germination, but also be very beneficial to flower bud differentiation and flowering and fruit setting.

The main thing is to need some inorganic fertilizer, and also need organic fertilizer, these fertilizers are helpful to jujube trees, and the help is particularly obvious.

Organic fertilizers such as compost, manure, circle fertilizer, crop straw, cake fertilizer, microbial fertilizer, and fishy fertilizer should be used as the mainstay, and inorganic chemical fertilizers should be used in an appropriate amount to make organic and inorganic fertilizers work together.

It is necessary to use inorganic compound fertilizers, because these fertilizers still need a lot, and this fertilizer can meet some energy needs.

The fertilizer elements required by jujube trees in each growth stage are different, from budding to flowering period to nitrogen-based, June to early August is the peak period of young fruit development and root development, nitrogen fertilizer and potassium fertilizer are required, base fertilizer in spring and autumn, but autumn application is good before the fruit matures to the defoliation, the tree continues to accumulate nutrients, it is the second year of the tree body buds and long leaves of the root base of the jujube tree planted and survived, and can be fertilized after germination and growth and leaf development. Because only when the branches and leaves grow, the root system elongates to absorb nutrients for the upper growth.

Fertilization of jujube trees is a comprehensive consideration. Generally, long-acting fertilizer is applied in autumn; Top dressing and spraying fertilizer were mainly nitrogen fertilizer before flower bud differentiation, which could meet the growth needs of budding branches and leaves, promote flower bud differentiation, and increase the number of fruit cells. Places with less precipitation are also very suitable for planting, but the demand for fertilizer in the planting process of jujube trees is relatively large, and the lack of fertilizer will cause low yield of jujube trees, so in order to obtain higher yields, we must pay attention to fertilization and supplement the nutrients in the soil to ensure the vigorous growth of the tree.

The flower buds of jujube tree are differentiated in the current year, differentiated many times, differentiated with growth, and the differentiation time is long and the number of differentiation is large. Therefore, jujube blooms in large quantities, takes a long flowering time, and consumes more nutrients. In production, it is often due to insufficient nutrition, resulting in a large number of flowers and fruits.

After the differentiation of flower buds, nitrogen, phosphorus and potassium mixed fertilizer was used as the main fertilizer, which was conducive to fruit development and root growth, and could improve fruit quality.

In order to increase the storage nutrition of the tree, we should strive to apply top dressing as soon as possible, and apply the Fujinmen compound biological fertilizer before the fruit is harvested, at this time, the leaves still have a relatively high photosynthetic efficiency organic fertilizer can increase the nutrients of the plant, so that more nutrients are stored in the fruit, and the starch is converted into soluble sugar, so that the taste is more sweet, crisp and delicious, and the yield of jujube can be improved. Available phosphate fertilizer and available potassium fertilizer, such as superphosphate, potassium dihydrogen phosphate, diamine phosphate, plant ash invading solution and trace elements boron, manganese, zinc, iron, magnesium, copper, etc. Top dressing should be supplemented with nutrients in time according to the phenological period of jujube trees, and the needs of the growth and development of various organs in different periods should be supplied.

If the vegetative growth is too strong in the initial fruiting stage, phosphorus fertilizer is the main fertilizer, combined with potassium fertilizer, and less nitrogen fertilizer is applied. If the vegetative growth does not meet the requirements, the fertilization is mainly phosphate fertilizer, with nitrogen fertilizer and potassium fertilizer, and the proportion of phosphorus, potassium and calcium fertilizer should be increased during the peak fruit period, so fertilization should pay attention to the combination of nitrogen, phosphorus and potassium fertilizer, and have some emphasis, especially to increase the proportion of potassium fertilizer, and increase the application of calcium fertilizer and other trace element fertilizers, so as to extend the life of its full fruit period as much as possible.

If the vegetative growth is too strong in the initial fruiting period, it is mainly phosphate fertilizer, with potassium fertilizer, less nitrogen fertilizer, and if the fertilization does not meet the requirements, it is mainly phosphate fertilizer, with nitrogen fertilizer and potassium fertilizer, and the fertilization in the full fruit period should pay attention to the combination of nitrogen, phosphorus and potassium fertilizer, and increase the proportion of phosphorus, potassium and calcium fertilizer.

In the fruiting period of jujube trees, phosphorus fertilizer can be mainly combined with potassium fertilizer, the proportion of phosphorus, potassium and calcium fertilizer should be increased during the fruiting period, and more nitrogen fertilizer should be applied after the fruiting period, which can promote the growth of jujube trees.

The main point of fertilization of jujube trees is that we must pay attention to the growth cycle of jujube trees when fertilizing, and we must carry out topdressing many times according to the growth cycle of jujube trees, and we must strictly control and preserve the fruits of jujube trees, so that we can make jujube trees grow better and the yield of jujube trees is higher.

In the growth stage, we should focus on strengthening nitrogen fertilizer, and there is an obvious effect, and in this process we must strengthen nutrition to promote growth, and slowly weigh to ensure that the fruit length is very good, so at this stage do not need to be vigorously fertilized.

It is necessary to pay attention to the flowering period of the jujube tree, and at the same time should also pay attention to the growth of the jujube tree, choose the appropriate fertilizer when fertilizing, and also pay attention to the amount of fertilizer used, pay attention to the combination of fertilizer and water, and so on.

Fertilizer for jujube trees. Jujube is a plant that is sensitive to dress-type fertilizers, and the demand is also very large. Fertilizers such as crop straw, compost, cake fertilizer, and microbial fertilizer are all applicable, but it is best to use a combination of organic fertilizer and inorganic fertilizer.

Compound fertilizer for jujube trees.

Jujube trees can be applied with compound fertilizers, mainly urea, superphosphate, potassium sulfate, diammonium phosphate, etc. However, compound fertilizer alone may cause soil compaction, and it is best to use it in combination with organic fertilizer.

Date tree fertilization time.

Jujube is generally fertilized in spring and autumn, but it is better to fertilize in autumn, and the specific time is from October to November. At this time, the root system is in the active stage, the wound heals faster, and a large amount of nutrients can be stored, which is conducive to the differentiation of new shoots and flower buds of the plant in the next year.

Jujube fertilization methods and tips.

1.Jujube can be fertilized by means of radial front injection ditch, ring ditch, strip ditch and other methods. For top dressing, it can be spread throughout the garden, rinsed, and fertilized in the cavity ring.

2.The base fertilizer of jujube trees should be applied once a year, and the specific time is before and after the fruit picking in autumn, and it can be applied according to the principle of "Jinguo fertilizer".

Nitrogen fertilizer can be used to plant jujube trees at home to improve the growth rate of plants, phosphorus and potassium fertilizers can also be used to promote flower bud differentiation of plants, and can also provide well-rotted organic fertilizer for jujube trees, so that the plants can grow better, and also need to provide reasonable water and light for jujube trees during maintenance, so that the plants can grow more vigorously.

1. Nitrogen fertilizer

Planting jujube trees at home can provide nitrogen fertilizer for the plants, which can increase the growth rate of the jujube trees and make the plants grow more vigorously. And when providing nitrogen fertilizer for jujube trees, it is necessary to add fertilizer directly to the soil, wait for the soil to absorb nitrogen fertilizer and then deliver it to jujube trees, so that the plants can absorb enough nutrients.

2. Phosphorus and potassium fertilizer

Phosphate and potassium fertilizers can also be used to grow date trees at home. Jujube trees lack phosphorus and potassium fertilizer, and the leaves will turn yellow and do not bloom, so it is necessary to provide an appropriate amount of phosphorus and potassium fertilizer for the plant when maintaining the jujube tree, so that the jujube tree can differentiate the flower buds as soon as possible and grow more fruits.

3. Organic fertilizer

When raising jujube trees at home, you can also use organic fertilizer, that is, farmhouse fertilizer, and when using organic fertilizer, you must choose well-rotted fertilizer, not unrotted fertilizer, because unrotted fertilizer contains a large number of bacteria, and providing this fertilizer to jujube trees will cause jujube trees to be infected with diseases.

4. Later maintenance

In the later stage of maintenance of jujube trees, it is necessary to provide an appropriate amount of water for the plants, soak all the soil, create a more humid growth environment for the jujube trees, and also provide suitable light for the jujube trees, so that the plants can carry out photosynthesis normally, and when the light is too strong, it is necessary to shade the jujube trees in time to let the plants grow healthily.

<> jujube tree base fertilizer can be used in the circle of round fertilizer, human manure, compost, etc., each plant is about 150-250 kg, for the weak tree needs to be added 45% nitrogen, phosphorus and potassium compound fertilizer about 1 kg, top dressing is carried out at the time of germination, each plant can be applied kilograms of urea and with a certain amount of phosphate fertilizer and boron fertilizer, in the young fruit, each plant can be used 45% compound fertilizer about 1 kg, after fruit picking can be sprayed urea sun tremor and potassium dihydrogen phosphate solution.

Since the nutrients absorbed from the soil during the growth and fruiting period of the jujube tree are taken away by the fallen leaves and fruits, and are not returned to the soil, it is necessary to apply fertilizer appropriately every year to keep the fertility of the soil from decreasing.

Jujube trees in the autumn (9-10 months) to apply sheep pen manure, rabbit manure, cow manure, pen manure, manure, human manure, biogas residue and other organic fertilizers (4-5 square meters per mu) plus an appropriate amount of potassium sulfate compound fertilizer (about 100 kg per mu) is the best.

In addition, in the fruit development period (July-August), an appropriate amount of potassium sulfate compound fertilizer should be applied, and the dosage per mu is about 70-80 catties.

According to the law of fertilizer demand of jujube trees, it is best to apply potassium sulfate compound fertilizer with a ratio of nitrogen (N), phosphorus (P2O5) and potassium (K2O) of about 20:10:20.
