How to control the growth of peppers after the crazy growth in the early stage?

If the pepper is ready to be planted too early, the temperature will be relatively high during the seedling raising period, and if it continues to rain for a relatively long time during the seedling raising period, it will cause the seedling to grow weakly and grow long. At the same time, the pepper does not cool down in time after the emergence of seedlings, which is also easy to cause the phenomenon of excessive growth of seedlings.

Secondly, after the planting of pepper, the fertilizer is high, especially the excessive nitrogen fertilizer, which leads to the vigorous vegetative growth of seedlings, inhibits reproductive growth, leads to the physiological metabolism of plants, hinders the normal and smooth transition of nutrients to reproductive growth, and then causes the occurrence of crazy seedlings.

Liufang suggested that in order to better and more effectively prevent pepper seedlings from growing, the sowing density is not recommended to be too large to prevent seedlings from crowding after emergence. And it is necessary to carry out seedling, false planting and planting in a timely manner.

At the same time, under the premise of strengthening ventilation and light transmission, temperature and humidity, reasonable fertilizer and water management and timely discharge of thin seedlings should be carried out. Pepper seedlings can also be prevented by spraying with a chlormequat regulatorWhen chlormequat controls the growth of pepper seedlings, it is necessary to pay attention to controlling the concentration of the agent to prevent excessive control

In this regard, we farmers can also cooperate with squatting seedlings to regulate, and squatting seedlings can be flexibly mastered according to the growth of seedlings and the characteristics of the combined varieties. For example, for the vigorous and long-growing pepper planting land, it should be properly squatted, and the seedlings can be squatted or not squatted if there are no signs of long-growth.

The old farmer suggested that the pepper planting land that has already stiffened the seedlings should not squat the seedlings, and should also consider the appropriate fertilizer and water promotion. Some late-maturing varieties can be moderately squatted, and medium-ripening varieties can be moderately squatted or not squatted. With the growth of pepper, fertilizer and water management should be strengthened in the later stage, and top dressing and watering management should be done to promote flowers and preserve fruits.

The main reasons for the growth of pepper seedlings are high temperature, small temperature difference between day and night, excessive amount of nitrogen fertilizer, high humidity or seedlings can not be transplanted in time, etc., which all cause pepper seedlings to be slender and thin, forming long seedlings. In addition to the above problems, it is also necessary to reasonably control water and fertilizer when cultivating pepper seedlings, so as to achieve the effect of promoting prosperity and growth.

The second is to control the temperature, if you want to grow a good pepper, you must first understand the growth habit of pepper, pepper is a temperature-loving plant, its growth temperature during the day can not be lower than 26 degrees, and the growth temperature at night can not be lower than 15 degrees, but after entering the winter, the growers in order to improve the growth temperature of pepper, to keep the pepper warm, will always increase the temperature in the greenhouse, so that the temperature in the greenhouse is very high, as everyone knows, this not only increases the phenomenon of pepper falling flowers and fruits, It will also inhibit its flower bud differentiation and create conditions for the production of bacteria, which is called excessive warmth, so we should properly insulate the pepper in winter, and ventilate it in a timely manner, and cover the surface of the greenhouse with a shade net to shade the greenhouse in summer.

The growth process of <> pepper is as follows:

1. Germination period: The germination period of seeds is from the germination of seeds, two ** leaves, to the appearance of the first true leaf, after germination and sowing, it takes a week. In the whole germination period, it is the transition stage of pepper seedlings from heterotrophic to autotrophic, and the nutrients are mainly supplied by seeds, and the absorption capacity of young roots is weak.

After sowing, it is necessary to promote rapid soil emergence to prevent the consumption of nutrients in the seeds, which may lead to weak seedlings;

2. Seedling stage: from the appearance of the first true leaf to the appearance of the first flower bud at the seedling stage, according to the sowing season. This stage is dominated by the growth of roots, stems and leaves, and is the period that lays the foundation for germination and differentiation in the next stage.

3. Flowering period: generally refers to the beginning of the opening of the first flower to the end of flowering. This stage is the critical period of pepper seed production, which is weak to the external environment and sensitive to temperature, humidity and light.

4. Fruiting period: from the time of flowering and fertilization of pepper to the time when the fruit is fully red and ripe and the seeds are ripe, this stage is an important period for the formation of seed yield. During the fruiting period, the expansion of the fruit and the embryonic development of the seed depend on the continuous transport of the products of photosynthesis from the leaves to the fruit and seeds.

Seeding, germinating, growing, flowering, fruiting, maturing, dying. Cycle.

Pepper is neither drought nor waterlogging tolerant, it is most suitable for growing in fertile, deep soil, good drainage, easy drainage and irrigation plots, generally before planting, apply some organic fertilizer, can be more conducive to growth. Peppers have reached the fruiting period, which is mainly affected by temperature, fertilizer, and water, resulting in poor growth. Pay attention to the field management of peppers on dog days to restore the growth of peppers.

Peppers like to grow in fertile, deep, well-drained soil, if the soil is poor, the bottom fertilizer is insufficient, and there is no timely topdressing, peppers are malnourished, natural growth is thin, and there is less flowering and fruiting.

Pepper has high requirements for nitrogen, phosphorus and potassium, and also absorbs a variety of trace elements. If the nitrogen is insufficient, the plant is short, the leaves are small, the branches are few, and the fruit is small. If there is too much nitrogen, the plant is prone to growth and infection. Phosphorus promotes the development of the root system and early flowering and fruiting.

If we use outdoor planting, we need to make some holes in the bottom of the container to prevent heavy rain from causing waterlogging and waterlogging of peppers. If it is planted on the indoor balcony, then in order to prevent soil erosion and dirty balcony during watering, there is no need to make holes in the container.

<> if there is a pesticide damage, we should spray a large amount of water in time. Or timely top dressing. Either with chemical antidotes, or with plant growth regulators.

to alleviate or relieve the damage of the drug. If it is the influence of temperature and other conditions, there are not many ways to think about planting in the field, but if it is greenhouse planting, it can be operated manually, so that the temperature and other conditions can reach the conditions suitable for the growth of green peppers. If the seedlings in the early stage are not growing well, the seedlings in the later stage are very slow, and the bottom fertilizer does not keep up when the seedlings are planted, and it is not good to grow.

Weather reasons: Because most of the green peppers are in summer, high temperature and drought, so the weather will affect the growth of green peppers.

Growing chili peppers is usually pre-planted with organic fertilizer because chili peppers are very dependent on fertile soil. If the pepper grows particularly poorly, you can also apply organic fertilizer to the roots.

Pepper has high requirements for nitrogen, phosphorus and potassium, and also absorbs calcium, magnesium, iron, boron, molybdenum, manganese, zinc and other trace elements. For example, when nitrogen is lacking in the soil, peppers grow poorly, with short plants, small leaves, few branches, and small fruits. However, in the early flowering stage, the nitrogen element requirement is not high, and too much nitrogen will cause flower and fruit drop.

Therefore, farmers should grasp the application rate of medium and trace elements to avoid poor growth of peppers.

1.Watering at the appropriate time In addition to watering the roots when transplanting and setting the seedlings, the seedlings are generally not watered until before flowering. Only light watering is required in continuous drought.

When the young fruit grows to about 3 cm long, in case of drought, it can be irrigated in a ditch, and moist management should be carried out, and flood irrigation should not be avoided. 2.Fine fertilization Peppers like fertilizer and are afraid of fertilizer, and are very sensitive to fertilizer.

First, it is necessary to achieve the combined application of organic fertilizer and inorganic fertilizer, and the organic fertilizer must be fully decomposed; Second, nitrogen fertilizer should be applied as appropriate for soil seedlings, especially urea should not be over-applied; Third, it is necessary to apply phosphorus, potassium and trace elements to prevent the occurrence of symptoms such as "loss of green"; Fourth, it is necessary to avoid high temperatures and use well-rotted low-concentration clean water manure for top dressing; Fifth, it is necessary to prevent defertilization, ensure adequate nutrition throughout the process, and prevent "lack of green" from falling yellow.

Chili peppers are a common food, and chili pepper cultivation is also common in our countryWhether it is a pepper seedling produced in the field or a protective cultivation, as long as the growth and development are normal, the seedlings should be early after transplanting, the new leaves should grow quickly, and the flowers and fruits can be orderly, but the abnormal growth of pepper also occurs from time to time. Defoliation during the growing season of peppers is a self-protective phenomenon of plants. When the external environment is unsuitable or the nutrients are insufficient, or the pepper is attacked by pests and diseases, the pepper is in the physiological response of self-protection, and will take the initiative to fall off part of the leaves on the plant to ensure the continuous growth of the plant.

Generally, the stem is short and thick, the internodes are tight, the leaves are thick, the color is dark green, the root system is many, the root color is white, the growth is stable, the seedling period is short after transplanting, and the new leaves elongate quickly. In the growth process of peppers, especially in the insulation cultivation of peppers in plastic greenhouses, when raising seedlings and transplanting, some abnormal growth phenomena often occur due to poor management, which affects the yield and quality of peppers. Some leaves lose green, and the leaf margins and tips die; Wilted seedlings, partially withered after high temperature on sunny days, partially withered on cloudy days.

Nitrogen fertilizer is applied to the seedbed, and medium and trace elements such as phosphorus, potassium, boron, and calcium are not applied; The seedbed is rough, the base fertilizer is insufficient, and the drought is dehydrated; The sowing amount is too large, the thinning is late, and the seedlings are squeezed to win glory; The continuous rainfall time is long, and the seedlings are not timely ventilated and closed; After a long period of drought, excessive irrigation causes root damage and physiological disorders. Before transplanting, the basal fertilizer was applied late and shallowly and quickly, and the root system was close to the fertilizer during transplanting. In order to shorten the slow seedling period and grow normally and stably, it is necessary to create conditions to prevent the occurrence of deformed seedlings.

Peppers grown in greenhouses generally need to be raised in greenhouses in order to grow strong seedlings and grow early. The bed soil of the seedbed must be carefully turned and dried, so that the soil is fine and clean, the sky is solid, the hands are pinched into balls, and the seeds are sprinkled on the ground. After sowing evenly, the seedlings can plump and firm at one time.

Secondly, balanced fertilization should be adopted. Rational management of water use. The irrigation methods are dry and wet, large dry and wet, small dry and small wet, more irrigation on sunny days, less irrigation or no irrigation on cloudy days, less irrigation during the cooling period, rooting water during the transplanting period, and one-time seedling water after slow seedling.

When it rains continuously, it should be ventilated, lit, and seedlings raised.

This is because the planting is too early to choose planting, and there has been rainfall or high temperature weather, so it will be particularly weak when growing, excessive talk about the growth of lead, and there is no cooling to appear abnormally good, you can go to fertilize more, choose nitrogen fertilizer to make the roots nutritious, grow vigorously.

This silver town must inhibit the growth at a time, and then the thing can go to apply less nitrogen fertilizer, but also pay attention to control the nutrition of the peppers, and then be sure to water more, only in this way will the peppers stop growing normally.

According to the abnormal situation, we can judge what is missing, and adjust its management in time, so that it can grow better.

Growth stages of chili peppers.

1. Germination period.

Peppers can only grow after sowing, choose plump, healthy seeds to sprinkle in the soil, and cover the soil with watering.

After the intermittent seed will germinate, grow two ** leaves, and then the cotyledons will continue to grow and develop, until the first true leaf is formed.

, to the seedling stage.

2.Seedling stage.

The pepper seedling stage refers to the period between the growth of the first true leaf and the growth of the first flower bud, when the stems, leaves and roots are grown.

Sufficient nutrients are needed to grow vigorously and prepare for bud differentiation, and the soil needs to be kept moist but not waterlogged.

3. Flowering period.

After the buds of the pepper grow, it enters the flowering period, and the plant will put nutrients ** on the flower buds, and the blooming flowers will.

Attract insects and bees for pollination, and if pollination is successful, the flowers will wither the next day and then grow.

Fruit. 4. Fruiting period.

The fruiting period of pepper is the stage from successful pollination to fruit ripening, when the fruit will gradually expand, the shape is like a water droplet, the color is emerald green, and after a period of growth, the plant is elongated, the color changes from green to red, if it is fully red, then.

Indicates that the pepper is ripe.

1. Fertilizer and water management.

After planting, it is necessary to rush to apply seedling fertilizer on sunny days, and the amount of each application should not be too much or too concentrated, otherwise it is easy to cause growth and delay flowering and fruiting. When.

After the first and second layers of fruiting, more fertilizer should be applied to promote the growth of the fruit. After the fruit is picked, the soil needs to be fully fertilized and watered in order for the plant to grow and bear fruit normally.

If heavy rain falls before the soil is dry after watering, leaf drop and dead plants are common, especially during the period between undulation and the beginning of autumn. Therefore, when irrigating, be sure to decide the irrigation time according to the weather forecast. The depth of irrigation should not exceed three-quarters of the furrow, and should be carried out at night or early in the morning, and the irrigation should be carried out urgently.

2. Cultivating and weeding, increasing the application of grass and wood ash, reducing humidity and aeration.

Through cultivating, the soil compaction is broken, the soil aeration is improved, the development of pepper roots is promoted, and a good soil environment is created for the growth of pepper. The tillage time should be selected in the sunny high temperature period or before the high temperature, shallow near the roots, deep between the rows, to avoid root damage. After cultivating, a large number of weeds lose water and die, and at the same time, it has the effect of soil disinfection and sterilization.

Combined with cultivating and increasing the application of plant ash, the first is to reduce soil moisture; The second is to increase soil nutrients.

3. Pruning and sharpening to prevent falling flowers and fruits.

When pruning pepper, keep the main trunk and 2-3 side branches, the lower axillary buds should be completely erased, and cut off the inner branches, old and sick residual branches, so that the inner chamber is ventilated and transparent, leave 2 leaves to tip in the branches above level 3, leave 1 fruit and 2 leaves to tip the newly grown branches, and remove the lower old and diseased leaves to promote the growth of the upper branches and leaves and the elongation and expansion of the fruit. At the same time, the soil is cultivated again to promote the growth of new roots, and fertilizers such as urea and potassium dihydrogen phosphate are sprayed with 2.
