What fertilizer can be used to raise citrus seedlings

After transplanting citrus seedlings, the main thing is to promote root extraction, pay attention to the supplement of phosphorus and calcium, which can promote root extraction, supplement a large number of available nitrogen, phosphorus and potassium to promote the growth of shoots and leaves, and use micro root calcium + full force to improve the growth of seedlings. Each time the shoots are showered and flushed, and each time the sprayed leaves are sprayed to supplement the Bili + Zhuangli, prevent and reduce the lack of nutrients in the yellow leaves, and keep the leaves green and strong.

Promote bud fertilizer, shoot fertilizer, shoot fertilizer1. Promote budding fertilizer: citrus saplings are planted in the roots, soaking the roots with rooting agent, which can promote the rapid growth of the root system, one month after planting, when the young trees begin to sprout, it is necessary to wet a certain fertilizer, the main fertilizer is compound fertilizer, and an appropriate amount of rotting organic fertilizer can also be added.

2. Shoot fertilizer: When fertilizing citrus, it should be fertilized according to the principle of one tip and two fertilizers, that is, put one tip and two fertilizers, and one tip and two fertilizers are more appropriate. It takes about 15 days for the new shoots to be extracted, and a balanced compound fertilizer + organic matter water-soluble fertilizer can be poured to promote the rapid growth of the new shoots.

3. Shoot fertilizer: citrus autumn and winter fertilizer is mainly applied with long-acting fertilizer, autumn fertilization is applied about 15 days before the autumn shoots, fertilizer is organic fertilizer plus balanced compound fertilizer, winter fertilizer is applied before and after the cold, winter fertilizer is mainly high nitrogen fertilizer, which can prevent flowering and fruiting in the coming year, and can ensure the safe wintering of citrus trees.

Hello! The fertilization of newly planted citrus seedlings needs to pay attention to the following points:1

Fertilization time: Newly planted citrus seedlings need the right amount of nutrients in the early stages of growth, but they should not be over-fertilized. In general, it is best to apply basal fertilizer within the first month after planting, followed by top dressing every other month.

2.Fertilizer selection: The fertilizers needed for newly planted citrus seedlings are mainly organic fertilizers and compound fertilizers.

Organic fertilizer can increase soil fertility and improve soil water and fertilizer retention capacity, and compound fertilizer can provide comprehensive nutrition for seedlings. 3.Fertilization method:

When fertilizing newly planted citrus seedlings, the fertilizer should be evenly sprinkled on the soil around the trunk, and then easily plowed into the soil with silver pats, and finally watered thoroughly. Do not sprinkle fertilizer directly around the trunk to avoid burning the roots. 4.

Fertilizer application: The amount of fertilizer applied to newly planted citrus seedlings should be appropriate, and not over-fertilization. Generally speaking, the amount of fertilization per Bochang should be controlled at about 1 3 of the diameter of the seedling canopy.

In short, the fertilization of newly planted citrus seedlings needs to pay attention to the aspects of fertilization time, fertilizer selection, fertilization method and fertilizer amount to ensure the healthy growth of seedlings.

Dear, I am glad to fertilize newly planted citrus seedlings How to fertilize newly planted citrus seedlings Dilute manure can be applied after planting for 1 month, and the amount of fertilizer is carried out on the principle of "thin fertilizer and more application"; It is necessary to apply 1-2 times of fast-acting fertilizer before the extraction of new shoots and during the growth period, and stop fertilization from August to October to prevent the extraction of late autumn shoots and winter shoots, and avoid freezing damage caused by consumption of nutrients; The annual fertilizer amount should be applied to each plant with an average kilogram of nitrogen fertilizer and a kilogram of urea, and an appropriate amount of phosphate fertilizer and potassium fertilizer should also be applied. Newly planted citrus seedlings need to be fertilized in moderation, but care should be taken not to overdo it. Here are a few suggestions:

2.Fertilizer type: You can choose organic fertilizer, compound fertilizer and other nutritionally comprehensive fertilizers, and pay attention to controlling the amount of nitrogen in the mill.

For newly planted seedlings, organic fertilizer is more suitable. 3.Fertilization method:

At the beginning of planting, fertilizer should be applied in small quantities and many times, each time about 5-8 kg of mu left and right. Increase the dosage and frequency regularly as growth progresses. In short, it is necessary to pay attention to science and caution when fertilizing the newly planted citrus seedlings, and determine the specific plan in combination with the actual local situation and the guidance of professionals.

Thank you for your patience, I hope mine is helpful to you, if you are satisfied, please give me a thumbs up and wish you a happy life.

In general, for newly planted young citrus trees, organic fertilizer should be applied at least twice a year, if it is applied to young trees planted in the current year, because it is applied once in planting, that is to say, organic fertilizer is applied once in winter and spring. Then, the second application of organic fertilizer, probably around June, this fertilization can be along the crown drip line, the high-quality rotten organic fertilizer is sprinkled on the ground, and then turned the ground, soil covering.

Although it is said that the approximate time is in June, it does not say that it must be at this time, and it is generally possible from the time of planting to October. Normally, it is only after the first bud germination of seedlings that thin decaying human manure can be applied, or rotten bran water, or biogas water, or fertilization can be applied with Strom. That is to say, before the first bud germination of seedlings to the maturity of the branches, it is necessary to apply organic fertilizer again, and try not to apply commercial fertilizers during this period to avoid fertilizer damage.

The specific fertilization time depends on the time when we plant, that is, the time when the buds germinate.

However, there is a problem that must be paid attention to when applying organic fertilizer to the planted citrus saplings in that year, that is, raw poultry manure cannot be applied, and it must be applied only after it is ripe. Because the newly planted citrus saplings have fewer roots and are damaged, the raw poultry manure aggravates the contradiction with the roots in the process of decaying and ripening, which is not conducive to the slow seedling and growth and development of the saplings. Therefore, when applying organic fertilizer, it is necessary to apply rotting organic fertilizer.

Foliar fertilizer was sprayed once <> 10 days after fruit picking, and again once at intervals of 10 days to promote rapid recovery of tree strength.

When the acidity of the orchard soil is medium or strong, 25 kg of grass ash can be applied to each plant after picking, and when the soil acidity is weak, an appropriate amount of organic fertilizer and compound fertilizer can be used.

When conditions permit, for orange trees with a yield of about 50 kg, 25-50 kg of farm fertilizer and kg of urea can be applied.

1. What fertilizer to apply after citrus picking

1. Spray foliar fertilizer about 10 days after fruit picking, and spray again once every 10 days, which can speed up the recovery of tree potential and ensure the normal growth of the tree in the following year.

2. For the soil with medium acidity (or strong), 25 kg of grass ash can be applied to each plant after fruit picking, and for the soil with weak acidity, an appropriate amount of organic fertilizer and compound fertilizer can be applied to the plant.

3. If conditions permit, organic fertilizer can be applied mainly, supplemented with fast-acting nitrogen fertilizer, for orange trees with a plant yield of about 50 kg, 25-50 kg of farmhouse fertilizer can be applied to the kilogram of urea, and the ditch is deeply applied around the canopy, and the soil is covered after application.

How to manage citrus after picking

1. Ditch drainage.

For orange orchards with deep soil and facing north, it is important to do a good job of ditching and draining when it is rainy, and keep it dry to promote flower bud differentiation.

2. Control pests and diseases.

1) Orange orchards are prone to pests and diseases, especially spider mites, and if pesticides are not used for control, they will still occur in large numbers after fruit picking.

2) It is recommended to spray acaricides (such as quick acaricides) with fast speed and strong knockdown power, and carbendazim or tobuzin can be added when spraying, which can not only kill mites, but also prevent diseases.

3) Foliar top dressing with urea and potassium dihydrogen phosphate to protect the leaves.

3. Clearing the garden.

1) After the fruit is picked, a comprehensive garden cleaning work is carried out, the dead branches, diseased and insect branches are cut, the diseased spots on the branches are scraped, the insect holes on the trunk are closed, and the wintering places of diseases and insects are eliminated.

2) The whole garden was sprayed with Baumé 1 degree stone sulfur mixture to reduce the number of basal trillions of diseases and insects in the next year and ensure the fruit yield in the next year.
