Hello, it is not recommended to use, although the farm fertilizer has a certain help to the tree, but it will carry a lot of germs, and in severe cases, it will burn the roots.
What is the best fertilizer to apply to fruit trees.
1. What kind of fertilizer should be applied to fruit trees?
1. It is better to apply urea, diammonium phosphate, superphosphate, potassium sulfate, organic fertilizer, soil miscellaneous fertilizer and other fertilizers for planting fruit trees. Chemical fertilizers can only play a role in supplementing nutrients for fruit trees, but cannot improve the structure of the soil, if only chemical fertilizers are used for a long time, it will cause the phenomenon of soil compaction, so that the nutrients in the soil are out of balance.
2. When using chemical fertilizer for fruit trees, it should be applied in conjunction with organic fertilizer or soil miscellaneous fertilizer, that is, organic fertilizer or soil miscellaneous fertilizer is the main fertilizer, supplemented by chemical fertilizer (chemical fertilizer can be applied as top dressing, such as fertilizer supplementation during the critical period of growth and development of fruit trees), so that it can have an immediate effect.
3. When the fruit tree has the symptoms of nutrient deficiency, it can be supplemented by more topdressing of riberyyanwo water-soluble fertilizer or topdressing outside the root, but the number of topdressing should be determined according to the growth changes of the fruit tree in the annual cycle, and under normal circumstances, 3-5 times can be topdressed.
2. When to fertilize fruit trees.
1. Two weeks before flowering.
At this time, the main application of available nitrogen fertilizers, such as urea and other fertilizers, can promote the growth of fruit trees, and at the same time enhance tree strength and increase fruit setting rate.
2. After the flowers fall.
At this time, the main application of fast-acting nitrogen fertilizer can supplement the nutrients consumed by the fruit tree during flowering and fruit setting, and at the same time reduce the probability of fruit drop, in addition to ensuring that the new shoots can grow vigorously.
3. After physiological fruit fall.
At this time, the fast-acting nitrogen, phosphorus and potassium fertilizers are mainly applied to the fruit trees to promote the growth of the root system, and at the same time, it is also conducive to flower bud differentiation and fruit expansion after fertilization.
4. Autumn shoots stop for a long time.
At this time, the fast-acting nitrogen fertilizer is mainly applied first, and some phosphate fertilizer and potassium fertilizer should be applied at the same time to promote the growth of the root system and improve the photosynthetic capacity of the leaves.
5. After fruit picking.
At this time, the application of fast-acting nitrogen fertilizer is the main thing, and at the same time, it is necessary to apply some potassium fertilizer, which can not only improve the photosynthetic function of the leaves of the fruit tree, prolong the life of the leaves, but also improve the nutritional level of the fruit tree, promote the growth of the root system of the fruit tree in autumn, and enrich the flower buds.

Fertilizing fruit trees is advised not to be blindly fertilized. Reasonable application of farm fertilizer must have an effect on the growth of trees. However, it should be noted that the rotted sheep feces must be used, and the roots and base fertilizer must be kept at 30cm.
The effect of citrus spraying foliar fertilizer on sea food.
It is recommended to have a water-soluble fertilizer, sea food fertile foliar fertilizer, to promote the preservation of flowers and fruits of fruit trees, enhance the color and luster, and improve the taste, and the effect is very good.
Before the flower bud differentiation, the fruit tree should be applied more high-nitrogen water-soluble fertilizer, which can make the fruit tree multi-differentiate flower bud. After the flower buds are differentiated, more water-soluble fertilizer of potassium dihydrogen phosphate should be applied, which can help the fruit trees to have large and colorful flowers and green branches and leaves. Top dressing should be carried out in time after the flowers have fallen to help the fruit trees resume growth.
A group of **, I hope it can help you.

Fertilization method of plant ash: dig a ring ditch 50 cm wide and 60 cm deep half a meter away from the fruit tree, put the plant ash into the ditch, water it thoroughly, and then press the new soil.
Spraying grass ash extract in the high temperature season can improve the drought resistance and high temperature resistance of fruit trees. 6 August continuous spraying 1 3 times 5% 6% grass ash extraction.
In addition, the transpiration intensity of leaves is weakened, and the ability of the tree to resist drought and high temperature in the wild can be enhanced. In winter, the base of the fruit tree is covered with a layer of plant ash to increase the ground temperature and prevent the roots from frost damage.
For fruit trees with powdery mildew, dig a ring ditch 10 20 cm deep at a distance of 15 cm from the plant, apply 10 20 kg of plant ash in the ditch, and cover it with a layer of thin soil, which has a good effect on the prevention and control of powdery mildew of fruit trees.

Sheep manure is treated as follows to fertilize fruit trees
1. Paifu decomposes macromolecules that are not easy to be absorbed by plants through microbial fermentation, enhances fertilizer efficiency, fixes nitrogen, and differentiates dust cultivation to release insoluble phosphorus and potassium nutrients;
2. Thorough decay can kill eggs and bacteria in feces. Through microbial fermentation, macromolecules that are not easy to be absorbed by plants are decomposed, and fertilizer efficiency is enhanced. Thorough decay can kill the eggs and germs in the feces.
Prevent the occurrence of root burning and seedling burning. Improve crop rhizosphere microbiota and enhance ammonia nitrogen fertilizer efficiency. Improve the resistance of plants to diseases and insects.
Sheep manure contains 24-27% organic matter, nitrogen (N), phosphorus (P2O5), potassium (K2O). Sheep manure contains more organic matter than other animal manure, and the manure is finer and the fertilizer is thicker. It is also a thermal fertilizer.
After fermentation, apply to the roots of fruit trees, not too close to the roots, otherwise burn the roots, generally the best autumn application, which is conducive to root healing and absorption.
Sheep manure, in addition to fertility, can also activate a large number of microorganisms in the soil, so that the soil that has been compacted can be improved, and at the same time, the organic matter in the orchard can be greatly improved, which is more conducive to the direct absorption of fruit trees.

Fresh ones are piled up for a while, and if they are dry, you can add some water. After heating, open it and it can be applied.

Peel the soil from the roots of the fruit tree, expose the root system, and scrape off the diseased skin with a knife. After drying for 2 3 hours, wipe the perimeter of the roots with fresh plant ash and cover the roots with soil. After treatment, the roots can be in 1 to 2 months**.
8 kg of plant ash and 100 kg of water soaked for 48 hours after filtration to make leach, the solution is mixed with fungicide and sprayed, which has a certain prevention and control effect on the early defoliation of fruit trees. When spraying plant ash fertilizer on the foliar surface, the soaking clarifier should be used to prevent leaf pollution.
Fruit trees are prone to dry blight and anthracnose at the seedling stage, and in severe cases, a large number of dead seedlings are caused. Spreading plant ash along the ridge, using 30 to 50 kg per mu, can effectively prevent the occurrence of these two diseases. In rural areas, we can prevent and control fruit tree pests and diseases, in addition to laundry detergent, there are also biogas slurry in the biogas digester, human urine, etc., which are more ecological and environmentally friendly pest control and pest control good things.
When the temperature is too high, the biogas slurry can be diluted to 80% concentration with water, which can control fruit tree red spiders, aphids and lepidopteran insects.
If you add laundry detergent, the effect of controlling pests and diseases is better. Plant ash contains a large amount of potassium ions, which can effectively weaken the strength of leaf transpiration water, promote the movement of carbohydrates, and enhance the resistance of trees to drought, high temperature, cold and other stresses. Plant ash can improve the photosynthetic efficiency of leaves, prolong the growth period of leaves, improve the vitality of leaves, and effectively prevent leaf atrophy, premature aging and defoliation.
Plant ash has a good effect on the control of root rot of pear, peach, hawthorn and other fruit trees.
The above is a detailed interpretation of the problem, I hope it will help you, if you have any questions, you can leave me a message in the comment area, you can comment with me, if there is something wrong, you can also interact with me more, if you like the author, you can also follow me, your like is the biggest help to me, thank you.
