In the process of planting eggplant, what fertilizer is the most taboo to use?

The most taboo fertilizer for planting eggplants is farmhouse fertilizer that is not fully rotten. The farmyard fertilizer is generally applied by the roots in the hole, which affects the root system, and the delicate root system may be burned and withered by the large farmer's fertilizer that is being further fermented and dissipated, which will cause the slow growth of the above-ground plants and the yellowing of the leaves.

The most taboo thing about planting eggplant is that it has not yet rotted fertilizer, because the eggplant seedlings are actually not very tall and the leaves are thick, so the ventilation is poor, and if you use unrotted fertilizer, it is easy to produce bacteria and cause lesions.

The first is to avoid potassium chloride fertilizer (potassium chloride), almost the whole process of eggplant growth. The other is the seedling period to avoid ammonia (ammonia, ammonium bisinate) fertilizer application, will burn eggplant seedlings, in the high temperature season can not dig a ditch cover to apply ammonia-containing fertilizer, high temperature ammonia volatilization can still burn into the eggplant.

You can't use manure when planting this crop, and you can't use fertilizer that doesn't rot, because it will kill the plant.

Although there are many varieties of eggplant crops, but its basic traits have not changed, the root height of the plant is only developed, it likes fertilizer, the drought tolerance is poor, the stem lignification degree is high, the branches are many, the growth period is carried out at the same time when the seedlings are cultivated, and the vegetative growth and reproductive differentiation growth are carried out at the same time, and the eggplant is not a difficult vegetable to wait for from the nutritional point of view after 4 true leaves. Eggplant naturally likes nitrogen fertilizer, which is suitable for cultivation in soil rich in organic matter and strong water and fertilizer retention. In the growing period of eggplant, the requirement for nitrogen fertilizer is relatively high.

Nitrogen deficiency before flowering and flowering, the most taboo fertilizer for planting eggplant, I have to say that there is no completely rotted farmhouse fertilizer, and farmhouse fertilizer is generally applied by the roots of the hole, affecting the root system, and the delicate root system may be further fermented and dissipated by the large farmer's fertilizer burned and withered, affecting the slow growth of the plants on the ground.

Fertilization at the <> seedling stage: The nutrition of eggplant seedlings is very important for it, because only when the soil nutrition is high can the eggplant seedlings with strong roots be cultivated, so it is necessary to pay attention to the application of certain basal fertilizer at the seedling stage. The base fertilizer can be used organic fertilizer, potassium sulfate, calcium phosphate, etc., although eggplant is a very fertilizer-eating crop, but it is also taboo to apply too much fertilizer at one time, and the demand for nitrogen fertilizer is very large in the full fruit period.

However, when it is high temperature, it should be the principle of "many times and a small amount", apply less fertilizer at a time, and apply more times at a time, so as not to be idle.

Eggplants are long throughout the growth cycle and have deep roots, so fertilization is key. When we fertilize the eggplant in the summer phase, especially in the high temperature phase, we use a small amount of fertilizer multiple times. For example, the use of urea is generally about 10 kg per mu, followed by planting eggplant, in the summer when the high temperature and rain and humidity are also very large, it is taboo to use some powdered type of fertilizer, or manure fertilizer, such a fertilizer type is easy to be washed away by rain, rarely can penetrate into the soil, and finally the eggplant itself can not absorb any nutrients Rural open-air eggplant fertilization needs to be carried out according to the characteristics of eggplant fertilizer, the growth period of eggplant is long, the demand for nutrients is large, and there are different growth needs in different growth stages. Therefore, fertilization should be determined according to the growth of eggplant.

When fertilizing eggplant, we should pay attention to the use of fertilizer envy containing reed material, and the unrotted chicken manure in the farmhouse fertilizer must not be fertilized for eggplant. When choosing to use nitrogen fertilizers such as ammonium sulfate, urea, and ammonium bicarbonate, it is also necessary to use them strictly according to the instructions, so as not to cause poor growth of eggplant due to improper fertilization.

Eggplant should not be applied to fertilizer containing nitrate nitrogen, the main edible part of eggplant is, its fruit, eggplant fruit is a non-bright branch is often good vegetable, is to enrich our "vegetable basket" a very delicious berry, consumers always like the appearance of the eggplant fruit that grows better, Jing Pa Min As the saying goes, "goods sell a skin", it is not false at all, if in the later stage of eggplant coloring, continue to apply fertilizer containing nitrate nitrogen, it is easy to cause poor coloring, and the colored fruit is back to green, although it does not affect the edible, But to affect the appearance of eggplant, potassium nitrate also contains a certain amount of nitrate nitrogen, eggplant coloring stage, it is not easy to apply, you can use potassium dihydrogen phosphate, potassium sulfate, etc.

The most taboo fertilizer for eggplant is the farmhouse fertilizer that is not fully rotten. Eggplant has a great demand for nitrogen in the fruiting period, but under high temperature weather conditions, it is necessary to adopt the high-level "small amount and many times" fertilization method to avoid excessive application amount for the second time. Generally, top dressing is carried out once every 7 days or so, and it is used together with phosphorus and potassium fertilizers.

1. Reapply basal fertilizer. Eggplant is a fertilizer-loving and fertilizer-tolerant crop, with a long growth period, and in order to obtain high yields, sufficient basal fertilizer must be applied before planting. The amount of basal fertilizer accounts for about 1 3-1 2 of the total amount of fertilizer.

Generally, 5000-7000 kg of high-quality decomposed organic fertilizer (chicken manure, horse manure, cow manure, pig manure, etc.) is applied per mu, and it is best to apply 2 3 generally, 1 3 with an appropriate amount of nitrogen, phosphorus, potassium compound fertilizer 25-50 kg, and then apply it intensively into the planting ditch or planting hole.

Second, top dressing in stages. Eggplant has a long fruiting period and needs to be topdressed several times. The amount of nutrients absorbed by eggplant increases rapidly after the full flowering period, so the key period of top dressing is from "door eggplant staring" to "four door bucket" harvesting.

During this period, top dressing can be done every 10-15 days, and 15-20 kg of ammonium sulfate or kg of urea per mu of top dressing can be applied each time, or 500-600 kg of decayed human feces and urine can be topdressed. The fertilization method can be furrowed, hole or flushed with water. If it is cultivated in the high temperature season or greenhouse in midsummer, it should be avoided to be applied with water to prevent the volatilization of the active ingredients, resulting in reduced fertilizer efficiency and fertilizer damage.

3. Spraying fertilizer outside the roots: eggplant leaves are yellow due to nitrogen deficiency and magnesium deficiency near the main vein, and defoliation often occurs and affects the yield. In order to make up for the lack of root fertilization, foliar fertilizer can be sprayed with urea, potassium dihydrogen phosphate, magnesium sulfate, etc. according to the growth of eggplant from the fruiting period.

Generally, once every 7-10 days, spray 2-3 times in a row.

The eggplant itself does not have high requirements for fertilizer, but the temperature is high in summer, and improper fertilization can easily cause fertilizer damage.

1. Avoid excessive one-time fertilizer application. Eggplant has a great demand for nitrogen fertilizer in the full fruiting period, but under high temperature weather conditions, the fertilization method of "small amount and multiple times" should be adopted, and the one-time application amount should not be too large. Generally, top dressing is done once in about 7 days, and 10 15 kg of urea is applied per mu each time.

Second, do not apply with water. Many vegetable farmers have the habit of applying chemical fertilizers with water, but it is very unsuitable in hot weather conditions in summer. Because of the high temperature, nitrogen fertilizers, especially ammonium bicarbonate, are easy to decompose and volatilize, and the ammonia produced by decomposition not only reduces the fertilizer efficiency, but also easily causes eggplant ammonia poisoning.

Therefore, when applying fertilizers such as urea and ammonium bicarbonate, it is necessary to take furrow application or hole application.

Three taboos are to apply nitrogen fertilizer alone. When topdressing, it is not possible to apply only nitrogen fertilizer every time. In the full fruit period, phosphorus and potassium fertilizer should be applied 2 or 3 times, and ternary compound fertilizer is best used to meet the needs of eggplant growth and fruiting, and it can also play a role in improving the quality of eggplant.

The nutrient demand of eggplant is relatively large, and the type of fertilizer and the amount of fertilizer required at each stage of eggplant are not very different, so reasonable and effective fertilization plays a key role in whether eggplant can achieve the purpose of high yield and high quality.

What fertilizer do eggplants need and how to fertilize eggplants well?

1. Choosing eggplant bottom fertilizer to plant eggplant bottom fertilizer is insufficient, which is directly related to whether eggplant can grow smoothly and whether weak seedlings and diseased branches will appear in the process. There are two main characteristics of eggplant bottom fertilizer: one is that the fertilizer supply needs to be long-lasting and balanced, and the other is that the nutrients should be comprehensive.

The fertilizer should be mainly organic fertilizer, supplemented by chemical fertilizer, and then according to the nutrient demand for eggplant growth, some potassium fertilizer can be added. Thirty to fifty quintals of pig manure or other livestock manure per mu, eighty to one hundred quintals of soil miscellaneous fertilizer, twenty to thirty quintals of soil ash, and fifteen to twenty kilograms of superphosphate can be applied in layered or holes. 2. Eggplant seedling fertilization At this time, the purpose of fertilization is mainly to cultivate strong seedlings, so that the stems and leaves of the seedlings are rapidly thickened, the branch internodes become shorter, and the root system is more developed.

You can choose to add a kilogram of nitrogen fertilizer, if the soil temperature is low, you can spray the foliar surface of eggplant with one-thousandth of urea with water, which can make the leaves green, and at the same time, you can also cultivate strong seedlings, add nutrients to the leaves, and promote the differentiation of flower buds. 3. After eggplant planting, you can choose to use urea, potassium dihydrogen phosphate, magnesium sulfate and other solutions to spray the foliage, about once every seven to ten days, and spray two to three times in a row; If the eggplant has a long flowering period and more flower buds, urea can be supplemented once or twice, about 15 kg per mu. At the same time, in order to promote root growth, you can choose to apply sea elf root solution once or twice, so as to improve the disease resistance and stress resistance of eggplant plants.

Chicken manure contains a lot of nitrogen, and direct use will cause eggplant to grow too luxuriantly, but the fruit will become smaller and deformed, and in serious cases, there will be problems such as poor growth and yellowing of leaves. It is best to compost chicken manure to allow the organic matter in it to be fully matured before use. 2.

High potassium fertilizer: Eggplant needs a certain amount of potassium during the growth process, but excessive application of potassium fertilizer will cause damage to the root system of eggplant, affect the absorption of water and nutrients, and cause problems such as smaller and deformed eggplant fruits. Therefore, the use of potassium fertilizer needs to be well applied at a good rate and timing.

3.Excessive nitrogen fertilizer: Eggplant needs a certain amount of nitrogen fertilizer in the late growth stage of the eggplant, but excessive application will cause the eggplant to grow vigorously, but grow a large number of leaves and branches, which will make the fruit smaller and deformed, and it is also prone to pests and diseases.

Therefore, the use of nitrogen fertilizer needs to be well controlled in terms of application amount and timing to avoid overdose. I hope mine is helpful to you, can you please give a like (rate it in the lower left corner), thank you

As a vegetable that likes a warm and humid environment, eggplant has a greater demand for fertilizer, but at the same time, there are some fertilizers that it is most taboo for, and the following are the three most taboo fertilizers for eggplant: 1Chlorinated sodium fertilizer.

Chloride ions have a strong inhibitory effect on the growth and development of eggplant, and sodium chloride fertilizer is rich in chloride ions, if used too much, it will lead to yellowing, cracking, death and other phenomena of eggplant leaves. 2.Ammonium nitrate fertilizer.

Although the nitrogen content in ammonium nitrate fertilizer is high, the nitro ions in it will be decomposed into oxygen, which is easy to drown the roots in rice, thereby affecting the ability of rice to absorb nutrients, resulting in yellowing of eggplant leaves and wilting in the high land zone. 3.Organic fertilizers that are not well rotted.

The use of incompletely decomposed organic fertilizers will cause damage to the root system of eggplant, which is prone to root rot, yellowing of leaves, diseases and pests. Therefore, the organic fertilizer should be stacked before application until it is fully decomposed. To sum up, the three most taboo fertilizers for eggplant are sodium chloride fertilizer, ammonium nitrate fertilizer and organic fertilizer that is not fully decomposed.

In order to ensure the growth and development of eggplant, we should choose the appropriate fertilizer according to the actual situation, and control the dosage, and pay attention to the reasonable application method of fertilizer to avoid damage to eggplant.
