What causes premature eggplant aging?

1. The eggplant with low temperature during the expansion period is a summer crop, and the growth is too vigorous and disturbed, such as unreasonable fertilization in the later stage, which can easily lead to the lack of potassium, boron and zinc in the eggplant; 2.Cause the phenomenon of burning roots and soaking roots. Of course, less fertilization will also cause poor development of eggplant, which shows the strict requirements of eggplant for nutrients.

3. If there is too much water, the eggplant will grow old if it does not grow large? It's still stiff and hard! 4 ways to solve, too much water will inhibit the normal metabolism of the root system, and then the orange will cause the inch-plum eggplant to grow small and old.

4. Hormone overdoseNow farmers blindly want to make crops bigger and develop faster, and generally spray growth hormones such as bulking agents, but excessive growth stimulation.

1. Manifestations of Progeria.

In the middle and late stages of growth, the rhizome gradually senesces, the ability to absorb nutrients becomes weaker, the growth nodes become more and more loved, the height of the surrounding leaves exceeds the growth point, the comprehensive growth of the seedlings becomes weaker and weaker, and the leaves become more and more yellow and have no luster. In the later stage, the eggplant basically could not sit on the fruit, the color was dull, the fruit expansion rate slowed down, and even the eggplant fruit stopped expanding.

2. Causes of Progeria.

1.Eggplant seedling raising link or planting seedling growth link because of too much bottom fertilizer, yellow leaf disease will occur during the period, but the rhizome can not be correspondingly sound, in the late growth stage or the growth of the link, the main stem nutrition can not be provided, which also leads to the occurrence of premature aging.

2.Eggplant is a high-fertilizer crop, and the demand for chemical fertilizers is also very large, so it is very important to continue to maintain the nutrient supply of eggplant in the middle and late stages, so if the nutrient supply is not enough in the middle and late stages, it will also lead to the occurrence of premature aging of eggplant.

3.The depth of the cultivated soil layer is insufficient, and the general micro-tillage machine rake the depth of only 10cm, which seriously limits the development trend of rhizome extension. It can be done 20cm, which is conducive to getting rid of the bottom of the plow.

4.Eggplant seedlings occur tall seedlings, which may be caused by the high temperature control of eggplant in the early growth stage of greenhouse seedlings or greenhouse seedlings, mainly due to the relative lack of light or too much bottom fertilizer, resulting in tall seedlings.

3. Prevention and treatment of premature aging of eggplant.

1.After planting, squat seedlings appropriately to promote rhizome growth: After planting, water enough planting water for eggplant Tongqing, and maintain a relatively high temperature and low humidity environment in the greenhouse to promote the emergence of new roots. Early slow seedlings, eggplant slow seedlings after proper water control. Cultivating and turning the soil promotes the rooting of rhizomes and the growth of rhizomes.

2.Reasonable fertilization, foot fertilizer, appropriate partial nitrogen fertilizer: different from Chaotian pepper and tomatoes, the requirements for base fertilizer are quite high, and the bottom fertilizer can increase the total number of eggplant columns, and the columns are more easy to pollinate and hang fruits.

When planting eggplant, we should pay attention to the increase of base fertilizer, 1 mu of manure farmhouse fertilizer 3-4 tons, diammonium phosphate 40 kg, phosphate fertilizer 75 kg, potassium sulfate 20 kg, urea 10 kg.

Eggplant grows particularly vigorously in the early stage of growth, eggplant bears more fruits, sufficient water and fertilizer, eggplant grows to the middle stage, the root system begins to age, and the overall aboveground growth will become slower and slower after the root system aging, resulting in the eggplant growth point getting shorter and shorter, and the leaves on the edge are higher than the growth point. The early growth stage of eggplant is relatively vigorous, and the amount of flowering and fruiting is relatively large, so there is nothing wrong with it. However, in the middle and late stages of growth, it will be found that the root system of eggplant begins to gradually age, and the absorption capacity of nutrients and water is weakened, which inhibits the growth of the entire aboveground part, and finally the growth point is lower and lower.

The root cause of premature aging is in the root system, so it is necessary to nourish and promote roots. Only watering without top dressing, watering two to three times, with organic fertilizer containing humic acid and amino acids, fertilizers containing nitrogen, phosphorus and potassium do not use or use as little as possible, and the effect can be seen in 10 to 15 days. The cultivated varieties of eggplant in South China are mainly heat-tolerant, moisture-tolerant, disease-resistant, large-fruited, high-yielding, medium-late ripening, and there are many commercial varieties.

All localities can choose early, medium and late maturing varieties with various types of disease resistance, high quality and high yield according to local customs.

You can use a large number of elements of nitrogen, phosphorus and potassium content of 20-20-20 water-soluble fertilizer for dropper or foliar spray, 80-100 grams per mu, spray every 10 days, 2-3 times in a row, can make the young fruit grow under sufficient nutrients, so as not to have a large number of fruit drops. Improve plant resistance to stress. Foliar spraying of new high-lipid film + 750 times of potassium dihydrogen can be sprayed twice in a row to improve the overall stress resistance of the plant and alleviate the problem that the plant growth point is not long.

This premature aging occurs in early spring, late autumn, and improper temperature management during greenhouse cultivation, and the overall yellowing will generally occur, and the influence of temperature is also the most direct obstacle factor. When cultivating on land in spring, due to the unstable temperature outside, high and low, it is easy to appear aging seedlings are removed from the top of the growth of eggplant branches and leaves, so that the eggplant can focus on growing fruits to retain nutrients, and to prevent insects Red spiders, tea yellow mites, leaf miner flies, and whiteflies are particularly serious, and it is time to pay attention to such a situation.

It may be that the soil is not abundant and the eggplant is not fertilized regularly, so that the eggplant fruit has fallen flowers. There is a way to remedy it, but it also requires some skill.

It is mainly caused by the occurrence of insect infestation and the lack of timely spraying of insecticides. There was no remedy but replanting.

It may be because the drought does not replenish water in time, or it may be affected by some pests, if the premature aging is not very serious, you can carry out hydration and fertilization, and supplement the sunlight to remove the pests.

What causes premature eggplant aging? What can be done when planting to avoid premature aging? Progeria is a problem of the root system and should be adjusted in time.

Lack of fertility, severe occurrence of pests and diseases, and an inappropriate environment can all lead to premature aging. Root burning, lack of fertilizer, pests and diseases, environmental and other factors can lead to premature senescence. The main cause of premature aging of eggplants is the lack of fertility.

1. Eggplant is over-applied with nitrogen at the seedling stage or transplanting stage, and the growth is vigorous, but the root system can not be improved accordingly. In the late growth period or vigorous growth period, plant nutrients are insufficient, leading to premature aging. Eggplant is a surplus crop, and the demand for fertilizer is very large, and the demand for fertilizer is also quite large.

Therefore, it is very important to maintain the nutrition of eggplant in the middle and late stages. If the nutrition ** is insufficient in the middle and late stages, it will also lead to the early aging of the eggplant. The eggplant seedlings are long-legged seedlings, which may be caused by excessive temperature control in the early stage of greenhouse seedlings or greenhouse seedlings, mainly due to the relative lack of light or excessive nitrogen application, forming long-legged seedlings.

2. Methods to prevent premature aging of eggplant: In the seedling stage, in order to prevent the growth of seedlings, it can be used. First, shading and cooling can provide a comfortable growing environment for eggplant seedlings. Second, replace nitrogen fertilizer with organic fertilizer.

When applying basal fertilizer, 30 50kg compound fertilizer can be applied every 667 years. After planting, squatting should be performed to promote root growth and development. Dig a soil layer of 30 50cm, spray no-tillage soil conditioner before planting, and apply 200g of compound fertilizer per 667%.

Dredged soil allows eggplants to take root.

3. After the eggplant is harvested and matured, a batch of eggplant should be collected in time without delay. Timely harvesting has a significant effect on preventing premature senescence of eggplant, which should be paid attention to. After harvesting a batch of eggplants, fertilizer should be replenished in time or sprayed on the leaves.

Timely removal of old, dead and diseased leaves of eggplant can not only make eggplant have more growth space, but also reduce the waste of nutrients and effectively prevent premature aging of eggplant.

1. Premature aging is a problem of the root system and should be adjusted in time. Premature aging can be caused by a lack of capacity, a high incidence of pests and diseases, and an inappropriate environment. Root burning, lack of fertilizer, pests and diseases, environmental and other factors can lead to premature senescence.

The main cause of premature aging of eggplants is the lack of fertility.

2. Eggplant was over-applied with nitrogen at the seedling stage or transplanting stage, and the growth was vigorous, but the root system could not be improved accordingly. In the late growth or vigorous growth period, the plant state is deficient in nutrients**, leading to premature aging.

3 Eggplant is a cash crop that has a high demand for fertilizer, and the demand for fertilizer is also quite large. Therefore, it is very important to maintain the nutrition of eggplant in the middle and late stages. If the nutrients are insufficient** in the middle and late stages, it will also lead to premature aging of eggplants.

4. Eggplant seedlings are long-legged seedlings, which may be caused by excessive temperature control in the early stage of greenhouse seedlings or greenhouse seedlings, and the main hidden erection is due to the relative lack of light or excessive nitrogen application, forming long-legged seedlings.

Premature senescence of eggplant may be due to excessive fertilization, resulting in insufficient nutrients in the root system, vigorous growth of branches and leaves, and finally premature senescence due to insufficient nutrition. In this case, it is necessary to apply fertilizer in an appropriate amount and control the number of fertilization. In addition, if the light is not enough, there will also be premature aging.

This kind of rock search situation mostly occurs in the greenhouse, and it is good to give enough light.

It may be because the amount of fertilizer is too much, it is likely to be a problem with the variety, or it may be a problem with soil fertility. Be sure to bracket in time, but also pay attention to the pruning of branches and leaves, to water in time, and try not to choose a high concentration of fertilizer.

It is very likely that it is caused by the relatively high degree of Wen people planted, and there is also the hidden energy of the Zhaodong because the soil has no fertility, or it may be caused by the lack of fertilizer, it may also be due to the appearance of pests and diseases or pests, or it may be due to the occurrence of rotten roots, and it may be due to lack of water.

It may be because it is not suitable for planting with other plants, or it may be because there is a reaction between the two plants, it may be because the soil has a problem with the ridge, it may be because the two plants clash with each other, or it may be because the growth of the two plants is different.

It may be a lack of nutrients, it may be that there is no timely watering, there is no control of the temperature outside the cavity, there is no control of the light intensity, and long-term exposure to the sun will lead to such a phenomenon of finger beams.

The main reasons may be that the temperature is relatively low, there is no timely fertilization, no light, excessive nitrogen fertilizer in the seedling stage, the nutrition of the auspicious section is not good, there is too much water, there is no timely cleaning of the water, and there are many bacteria in the soil.

Excessive nitrogen fertilizer during the growth period of eggplant seedlings or transplanted seedlings resulted in excess nutrients at the seedling stage and vigorous growth at the seedling stage, but the root system could not be improved accordingly. In the late growth stage or vigorous growth period, the lack of plant nutrients** can also lead to premature aging. The appearance of tall seedlings in the nursery stage may be caused by excessive temperature control in the greenhouse nursery stage or in the early growth stage of the greenhouse nursery stage.

Of course, at the same time, the relative lack of light or excessive nitrogen fertilizer leads to the formation of tall seedlings, resulting in the phenomenon that the aboveground part is not comparable with the underground part, and in this case, it is difficult to maintain nutrition in the later stage of growth.

Eggplant wilt is similar to Verticillium wilt. It is also a common disease in eggplant production. However, the infection rate is lower at the seedling stage.

It usually occurs after colonization. This is somewhat similar to the symptoms of Verticillium wilt. It is the yellowing of the edges and veins of the leaves, then the yellowing of half of the leaves until all the positive leaves are yellowed and wilted.

In the early stages, it also wilts in high temperatures, and sooner or later it returns to normal. In the later stages, the diseased leaves turn brown until they wilt and fall off, and finally only the stems remain.

The incidence of eggplant root rot is similar to that of the first two diseases. For example, in the early stages of the disease, the leaves will slowly turn yellow, wither during the day, return to normal sooner or later, and gradually turn yellow in the later stages. But unlike the first two, when the disease is severe, the epidermis of the taproot and lateral roots turns brown and the cortex appears to be in a state of decay.

Proper rotation can also be a good way to avoid the occurrence of diseases. Seedling cultivation can also help eggplants avoid diseases and increase yields.

Eggplant grows too vigorously in the early stage, bears a lot of fruit, consumes a lot of nutrients, and seriously ages the root system, which may also be caused by temperature, fertilizer and water or diseases. It is necessary to pay attention not to grow too vigorously in the early stage, not to fertilize too much in the early stage, and to keep up with the level in the later stage.

It is generally caused by too little fertility, and the best way is to fertilize the eggplant every half month.

After all, eggplant as a seasonal vegetable, plus it has a variety of ways to eat, and has the effect of clearing heat, widening the intestines, dispersing blood and stopping bleeding, many people like to plant a little in their own small yard, so I will take a look at the reasons for the growth of eggplant with you.

There are many reasons for the overgrowth of eggplant, and the most likely periods are seedling branching and cotyledon stage. At this time, the overgrowth is mainly due to the excessive sowing density and the failure to remove the mulch in time after the emergence of seedlings, resulting in overcrowding of seedlings and overgrowth. In the cotyledon development stage, if the temperature is not cooled in time or the temperature is too high, the seedlings will be overcrowded and grow.

Before slow sowing, due to continuous rainy days, the humidity of the seedbed is high, and more nitrogen fertilizer is applied, which is easy to cause overgrowth.

On the premise of ensuring the appropriate temperature of the seedbed, the mulch should be removed in time, and the natural light time of the seedbed should be extended as much as possible, so that the seedbed should have sufficient light and inhibit the vigorous growth of seedlings. At the same time, the temperature of the seedbed should be appropriately reduced. When half of the seedlings are unearthed in the seedbed, the temperature should be reduced to 25 during the day, and the night temperature should not exceed 15

Due to the high density of seedlings, the seedlings are crowded and overgrown with weeds, so it is necessary to guide the seedlings as soon as possible, open the seedling spacing, strengthen the management of the seedbed, spray foliar fertilizer in time, and supplement the nutrition of the seedlings.

For clumping plants, a growth regulator, such as chloroquine, can be sprayed on the leaves to inhibit their clumping.

The cuticle on the surface of eggplant stems and leaves is underdeveloped, and the amount of water evaporation is large, and it is easy to wilt. The plants are high in nitrogen, low in carbohydrates, poor in stress resistance, and poor in disease resistance. The rapid growth of eggplant seedlings leads to malnutrition, which can easily lead to late flower bud differentiation. Moreover, the number of flower buds is small, which leads to abnormal development of flower organs.

The fruit is easily deformed or stiff, grows slowly after planting, and has a low survival rate.
