Hello, orange trees can generally be fertilized with nitrogen, phosphate, potassium and other fertilizers. The orange tree generally refers to the orange tree, which is a plant belonging to the order Rutacea, Rutaceae, Citrus genus, and orange species, with more branches, branches expanding or slightly drooping, and fewer thorns on the treeThe fruit has a thick outer skin and a petal, and is mainly composed of juice bubbles and seeds. Fertilization of young trees The fertilization of young trees of orange trees is relatively simple, mainly basal fertilizer and top dressing;When planting, each orange tree needs to be applied basal fertilizer, and the basal fertilizer is generally applied with 60 catties of rotted farmhouse fertilizer and catties of superphosphate;After planting, in order to ensure the rapid growth of orange tree seedlings, water-soluble fertilizer can be applied to promote root growth.
Before the growth of new shoots, it is necessary to apply shoot fertilizer, mainly nitrogen fertilizer, when the new shoots grow, apply phosphate fertilizer and potassium fertilizer to promote their old maturity, so repeatedly, so that the young tree shoots 5-6 times a year, can achieve the purpose of rapidly expanding the canopy. Fertilization of fruiting trees For fruiting orange trees, fertilization is relatively complicated, and it needs to be fertilized about 4-5 times a year, which are germination fertilizer.

Summary. Hello, dear!At present, citrus uses more organic fertilizers, compound fertilizers, urea, water-soluble fertilizers, and foliar fertilizers.
Hello, dear!At present, citrus uses more organic fertilizers, compound fertilizers, urea, water-soluble fertilizers, and foliar fertilizers.
Organic fertilizer is a necessary fertilizer for citrus plantingOrganic fertilizer can be the purchase of commercial organic fertilizer and their own farmhouse fertilizer, generally buried in the winter fertilizer or spring fertilizer, organic fertilizer can improve the content of soil organic matter, can promote the healthy growth of citrus, but also improve the quality of citrus, at present, many manufacturers to promote biological organic fertilizer, the effect is better, but the cost is higher. If the amount of fruit is large, it can also be applied together with strong fruit fertilizer half a month before spring shoot germination.
Compound fertilizer is the main fertilizer of citrus Generally speaking, when applying organic fertilizer in winter, it is recommended to bury half a catty of compound fertilizer at the same time, the main purpose is to provide sufficient nutrition for the flowering and fruiting of citrus in the second year, and the other is to apply a strong fruit fertilizer before the autumn shoots, generally high potassium compound fertilizer, generally speaking, the application amount should not exceed each tree. Note that compound fertilizer is best applied in annular furrows.
Urea is used for citrus shoots and rapid nutritional supplementation Urea can be used for the growth of young trees or shoot promotion, etc., for some trees with poor strength, urea can be used once before spring shoot germination to strengthen vegetative growth, and can also be used once after flowering, so as to supplement the loss of nitrogen during flowering.
The use of water-soluble fertilizer is becoming more and more common With the rise of drip irrigation, the use of water-soluble fertilizer is increasing, generally speaking, water-soluble fertilizer is divided into alternative compound fertilizer, urea's large number of elements water-soluble fertilizer and functional fertilizer, water-soluble fertilizer is easy to use, but the cost is higher. For example, many fruit farmers use amino acid water fertilizer to improve the frost resistance and stress resistance of citrus, and use humic acid and alginic acid functional fertilizers such as sea elf to improve the physiological yellowing of citrus.
Foliar fertilizer is suitable for rapid supplementation of nutrientsFoliar fertilizer is used on citrus, mainly for the rapid and convenient supplementation of nutrition, such as potassium dihydrogen phosphate to promote the aging of new shoots, promote the sweetening of fruit color, etc., and the use of foliar fertilizer to assist in flower and fruit preservation, etc., all need to use foliar fertilizer.

It is best to use organic fertilizer, compound fertilizer or water-soluble fertilizer fertilizer for orange trees.
1. Organic fertilizer
When fertilizing orange trees, organic fertilizer is necessary. It is important to know that the proper use of organic fertilizer for it can prevent root problems, and in addition, organic fertilizer can be used with purchased finished products, as well as oranges and optionally farmhouse fertilizer. However, farmyard manure must be fully decomposed before it can be used.
2. Compound fertilizer
Orange trees can also choose to use compound fertilizer, because compound fertilizer is nutritionally balanced and cost-effective. Different periods should choose different compound fertilizers for it, such as high nitrogen compound fertilizer should be selected at the seedling stage, and high potassium compound fertilizer should be supplemented at the fruit expansion stage.
3. Water-soluble fertilizer
With the popularization of drip irrigation equipment, the frequency of use of water-soluble fertilizers in the process of cultivating orange trees has gradually increased. Water-soluble fertilizer contains a variety of trace elements, which are more beneficial for the growth and root system of orange trees.
Pay attention to orange tree fertilizer
1. The needs of orange trees for various nutrients should be fully met, and it is recommended to apply more organic fertilizer, rational application of inorganic fertilizer and formula fertilizer.
2. Fertilization is guided according to the results of leaf analysis, orchard soil analysis, fruit formation, and orange phenology.
3. Mainly soil fertilization, combined with foliar fertilization. The methods of annular furrow application, strip furrow application, hole application and soil surface fertilization were adopted.
4. Orange trees have higher requirements for nutrients, and need to be fertilized in time to meet the needs of nutrients for plant growth and development.

Orange trees can generally be compounded.
If you want the orange tree to grow sweet fruits, you can apply compound fertilizer to it, the content of compound fertilizer should be mainly potassium fertilizer, supplemented by nitrogen and phosphorus fertilizer, to promote the growth of fruits, pay attention to the fertilization, you need to combine the soil to let the roots of the orange tree better absorb nutrients.
Frequent application of thin application, mainly nitrogen fertilizer, with the application of phosphorus and potassium fertilizer, spring, summer and autumn shoot extraction period fertilization 5-6 times a month each time to apply ammonium carbonate or urea catty. 1-3 year old young trees should be applied 100-400g of pure nitrogen per plant, and the ratio of nitrogen, phosphorus and potassium should be 1:(:
1 is appropriate. Adult trees should be fertilized four times, namely germination fertilizer, fruit preservation fertilizer, fruit strengthening fertilizer, and fruit picking fertilizer. The amount of fertilizer is generally budding and withering, only 2-3 catties of fertilizer fertilizer, a load of manure; 1-2 kg of phosphorus and potassium fertilizer + 1 kg of chemical fertilizer; 1-2 kg of fertilizer + 1-2 kg of phosphorus and potassium fertilizer; Fruit fertilizer (base fertilizer) is mainly organic fertilizer, and 50-100 kg of organic fertilizer + 1-2 kg of chemical fertilizer is applied.
Precautions for pruning potted orange trees
1. Tree selection. According to the different requirements of the upright and drooping nature of the fruit tree species and varieties, the tree shape of the potted fruit tree can be shaped with rich imagination, such as natural round head shape, tower shape, one-branch cliff shape, double-branched antler shape, three-branch cup shape, weeping willow shape, dragon curve shape, etc. Make it both beneficial to the result and aesthetic to enhance its ornamental value.
2. Spraying and shaping. Foliar spraying of plant growth retardants (such as mequartin, paclobutrazol, etc.) should be carried out 2-3 times during the vigorous growth period of potted fruit trees, which can make the branches thick, the internodes shorten, and the plants dwarf. In addition, the measures to promote flowering and dwarfing and pruning in shape mainly include wiping buds, topping, taking branches, bending branches, circumcision, returning to cultivation, renewing, pulling branches, etc.
The light is enhanced by opening the branch angle and thinning the long branches, dense branches and ineffective branches, etc., to create the ideal tree shape.
It can be saved, orange trees due to low temperature, weak light, excessive watering and other bad conditions will produce a large number of fallen leaves, as long as the roots, branch groups are not harmed, you can prune according to the situation, remove dead branches, appropriately increase humidity and reduce light, after about half a month new leaves can be sent out. >>>More
Leaf curls on orange trees can be caused by improper watering, dry air, aphids or root rot. If the plant is not watered thoroughly, sprayed regularly to maintain air humidity, and is not replaced with soil and sprayed with drugs, the plant will have leaf rolling.
The orange tree is relatively easy to raise, and it is best to buy the kind of flower pot, which is more convenient to raise at home, and can also be raised as a flower, which can be said to be the best of both worlds, and it will be easy for you to take care of, otherwise it will die after a long time, watering and basking in the sun can be, and you can pay attention to keeping it warm in winter. >>>More
1. Soil: When cultivating orange trees, ferrous sulfate needs to be applied to the soil to make it slightly acidic. 2. Water and fertilizer: >>>More
Physiological yellowing is a problem that you must face on the road to growing citrus, because it indicates the beginning of the decline of the tree, and then the decline in yield, fruit decline, and shortening of the production life will follow, especially harmful. >>>More
