When planting peppers, why should the seedling stage be controlled?

Among the many common reasons for pepper growth, improper fertilization and high soil moisture are the two most prominent reasons. Peppers caused by improper fertilizers are the most vigorous in terms of pepper growth, which is the excessive use of nitrogen fertilizers such as urea and ammonium, and the insufficient use of phosphorus and potassium fertilizers. Nitrogen is one of the three major elements needed for crop growth, and most fertilizers on the market today contain high nitrogen content.

In particular, farmers who rely on experience often have the wrong idea that "you can grow vegetables by applying more nitrogen fertilizer", so they often overuse nitrogen-based compound fertilizers or use a large amount of nitrogen fertilizers such as urea and ammonium. The result of excessive use of nitrogen fertilizers or nitrogen-based fertilizers is that the nitrogen content in the soil is too high, and the roots of the pepper during the growth period overabsorb nitrogen, resulting in the over-vigorous, excessive, over-dense frenzy of pepper branches and leaves. Branches and leaves that grow too much and are too vigorous will consume a lot of the absorption of pepper roots and the nutrients accumulated in the plant, thereby reducing the nutrients of reproductive tissues such as pepper buds, flowers, and fruits.

The roots of pepper are not developed, the roots are few, the soil is shallow, and it is not resistant to drought and waterlogging during the breeding period. However, in order to promote the rapid growth of peppers, some vegetable farmers often water and water too much, especially in the summer high temperature and rainy season, and timely field drainage after rain, so that peppers continue to maintain a strong growth momentum in a high humidity environment. Peppers are readily available after they are grown.

Usually when planting, dig a hole, put in the sapling, compress it into the soil, and finally water it. This season is usually planted in the morning or afternoon. But at this time, it is better to plant pepper seedlings with mulch to cover the soil.

This has a good effect on promoting the growth of peppers.

Some people often have Wangzhuang problems after planting peppers. When the peppers are growing vigorously, you can see that the pepper trees are growing well, with long branches and many leaves. Eggplants also have a lot of buds on them and may bear a lot of fruit.

But if you bloom, if these branches bloom, you will soon be thankful, and the peppers will not grow. The pepper tree is particularly vigorous, especially when it is tall and only blooms and does not bear fruit, which is the situation when the pepper grows vigorously.

When a new sprout is planted, it becomes a flower bud. This is the period when pepper seedlings are delayed, growing, and hanging buds. During this period, the nutrient requirements of peppers are actually relatively small.

Because before planting pepper seedlings, we have to prepare the land, so when preparing the land, we must put organic fertilizer into the soil, in fact, this organic fertilizer is the basic fertilizer, as long as it is added, it can fully meet the early growth needs of pepper seedlings.

I think the biggest possibility is that the peppers that grow can have a better spicy taste, otherwise they won't control the growth.

The vigorous growth of chili peppers is a common occurrence when growing chili peppers. When there is a situation of longevity, the first thing that comes to people's minds is to use drugs to control it. Or by managing fertilizer and water, reducing the number of fruits left behind, etc., to control the growth.

Of course, hanging branches can also be used to control the growth of peppers, as sometimes the slings of many friends' pepper planting sheds are very loose and some are particularly tight. In fact, this is not because of improper management, but because tightening the sling can help it recover its growth, and the relatively loose regulation can effectively control the growth rate of peppers and prevent them from growing.

Renovate the soil, water the peppers, fertilize, spray the nutrient solution, spray the poison, have a certain amount of sunshine, and do a good job in the management measures of insect control and pest.

The side and top branches of the pepper should be pruned, which is the most basic method and is more effective, which can effectively improve the situation.

It is still caused by malnutrition, so you can apply more fertilizer during the planting process, and you should also control the growth, and pay attention to the frequency of watering and fertilization.

Generally mid-late maturing varieties, long apprentices. The main reasons for the growth of peppers in the protected area in spring are that the soil is too wet, the relative humidity is above 80%, the nitrogen fertilizer or rainy weather for days, the relative humidity of the air is above 80%, the light is insufficient, the meal is insufficient, the ventilation is not good, and the peppers are often planted in the reserve. The first type of pepper often can't sit still due to high temperature and humidity.

Stop 10 to 30 days before planting, prepare basic fertilizer, shed top film cover, skirt, ditch drainage around the greenhouse, etc., to help plant seedlings when the humidity in the shed is low and the temperature is high, which helps to slow down the seedlings.

Nowadays, most peppers are planted for small seedlings, and they generally take root continuously, so their slow seedlings are very fast. When the pepper is planted with 5 6 leaves and 1 mood, it is different from the previous large seedling (7 8 true leaves). After the slow seedlings are planted, sprinkle once every 10 days, and can be injected with drugs such as Da Corning and Amicida to prevent the occurrence of diseases.

Plants should maintain a certain temperature, ventilate boldly, and reduce the humidity in the warehouse. When the minimum external temperature at night is above 15C, ventilation should be carried out day and night. After entering the high temperature stage in summer, you can use shade appropriately to reduce the temperature.

In the middle and late stages of plant growth, an appropriate amount of pruning should be carried out in time to make good ventilation, prevent the field from being blocked, and make the plant grow.

If the basal fertilizer is sufficient, no more fertilization and watering are done before flowering and fruiting. Especially covered with mulch. After the pepper sits firmly, water and fertilize appropriately according to the situation.

When fertilizing, it is necessary to control the amount of nitrogen fertilizer applied, and do not let plants with too much nitrogen grow well. During the flowering and fruiting period, it is necessary to coordinate the balanced relationship between crop nutritional growth and reproductive growth, prevent excessive growth of nutrients, prevent poor fruits, and appropriately control nutritional growth with growth regulators. The suitable growing temperature of pepper is generally 25-28 during the day and 16-20 at night.

When planting, the local temperature should not be lower than 15, so as not to affect the effect of delaying seedling raising. Generally, planting is carried out in the morning of sunny days, transplanting 1-2 seedlings per hole, slowing seedlings after planting for 5-7 days, slowing seedlings, watering once in time, and then adjusting the water, pecking out the seedlings, and planting chili sauce plants.

Please note that growing peppers in a plastic greenhouse will bloom, maintain the optimal temperature inside the warehouse before the fruit, generally not more than 3-5 hours, so as not to grow new shoots. That is to say, after maintaining the most suitable temperature in the warehouse for 3 to 5 hours during the day, it is appropriately increased by 1 2, and after maintaining it for 2 3 hours, it is adjusted to the appropriate temperature. Nighttime temperatures can be maintained at 15.

When the length of the pepper reaches 3-4 cm after sitting, watering together can harvest 2000 kg of potassium sulfate, 20-25 kg of potassium sulfate, 10-15 kg of potassium sulfate, and 8-10 kg of urea in Wudang, which can promote the expansion of pepper flowering fruits and small peppers. In the future, when the soil is dry within 10 cm of white, watering to keep the soil moisture at 70%-80%, and spraying potassium dihydrogen phosphate solution, borax solution, 3% paraquat solution on the foliar surface, can not only promote the expansion and transpiration of peppers, but also prevent some pests and diseases.

The main causes of pepper soil include poor ventilation of the seedbed on sunny days, high temperature of the seedbed, too much humidity, or excessive amount of fertilizer, too much sowing density, etc., in addition, if the light is not enough on rainy days, it will also lead to the phenomenon of pepper growth.

There are many reasons for the growth of peppers, as for the phenomenon of growth in the seedling period, it is mainly caused by the untimely ventilation of the seedbed on sunny days, the high temperature of the seedbed, the excessive humidity, the sowing density and planting density are too large, and the amount of nitrogen fertilizer is too large. At the same time, continuous rainy weather and insufficient light will also cause the occurrence of pepper growth.

One is that the fertilizer is too much, so this situation will occur. The other is that the planting time is not right, so it is recommended to plant in autumn. The last one is that you should pay attention to pruning, and cut off the excess branches.

Peppers like temperature, water, and fertilizer, and they need to be fertilized when they grow peppers.

Soil preparation is required before planting.

Fertilization during growth.

When the soil temperature of the seedbed is stable above 20, the seedlings emerge quickly, grow vigorously, have strong disease resistance, and have a mild disease. The seedling stage is cloudy and rainy, the light is insufficient, the seedling growth is weak, the disease resistance is poor, and the disease is serious; Improper management of seedling stage, such as sowing too early and too dense, not timely seedling, too shady seedbed, easy to get sick.

Reasonable seedbed. Choose sandy loam land with convenient drainage and irrigation, fertile soil and good air permeability as seedbeds, and choose rotation land for planting. The manure used in the seedbed is a disease-free fertilizer that is well rotted at high temperatures.

Seed dressing before sowing. Seed dressing with new high-fat film can keep warm, moisturize, absorb swelling, improve seed germination rate, and make seedlings robust. Repel underground pests and isolate viral infections.

Agricultural control. Once the diseased plant is found in the seedbed, it is immediately sprayed or irrigated with fungicide + root Shitong + tree protector to inhibit the virus transduction infection of the root and the leaves and fruits, and maintain the health of the plant transport system. 7-10 days for prevention and treatment, 2-3 days.

Dead pepper seedlings are a new type of pepper seedling promotion during the seedling raising period, which seriously affects the planting efficiency of pepper and brings huge economic losses to farmers. So what is the cause of the death of pepper seedlings? How can it be prevented?

Causes and preventive measures of pepper seedling death. 1. Pathogen infection. Pathogenic bacterial infection is the main cause of death of pepper seedlings, and the disease is mainly caused by pathogenic bacterial infection.

At the seedling stage and the early stage of planting, there are mainly blight, wilt and blight, which can lead to the death of pepper seedlings.

2.Continuous cropping. Continuous cropping will lead to improper accumulation of pathogens in the soil, increase the base number, and the invasion of pathogens from the wounds at the base of roots or stems, and spread under suitable conditions, resulting in a large area of dead seedlings.

3.Seeds or seedlings carry bacteria. Seeds or seedlings carrying bacteria are the main route of long-distance transmission of the disease and the main source of infection in new vegetable fields.

When sowing, the seeds and seedlings are not sterilized, which provides favorable conditions for the spread of the disease. 4.The seedling is not raised in the right way.

It has been proved that the incidence of nurseries applying nutrient substrate is lower than that of nurseries applying nutrient soil, the incidence rate of plots applying unfermented and decomposed organic fertilizer is higher, and the incidence of flat furrow planting is higher than that of ridge planting. 5.Unreasonable irrigation.

The irrational irrigation method also created favorable conditions for the development of diseases, among which the fields with flood irrigation or more irrigation times were obviously more serious, while the fields under drip irrigation were basically disease-free or mildly disease-free.

6.Improper fertilization. Excessive application of nitrogen fertilizer, insufficient application of phosphorus, potassium and trace elements, and application of farmhouse fertilizer or organic fertilizer that is not completely decomposed will lead to root rot, causing serious diseases and dead seedlings.

Precautionary measures:1Reasonable rotation.

Rotate according to the specific situation to reduce the base number of pathogenic bacteria in the soil. 2.Disinfection of seeds or seedlings.

Select varieties that pass quarantine and disinfect them before sowing or planting to kill the germs attached to the seeds and ensure the healthy growth of seedlings. 3.Soil disinfection.

If conditions permit, the soil can be disinfected, such as copper sulfate, formabi, etc. The planting holes can also be disinfected with drugs such as spirit and mold. 4.

Strengthen management. Increase the application of organic fertilizer, phosphorus and potassium fertilizer and trace element fertilizer to enhance plant disease resistance; The amount of water should be moderate to prevent flooding; Plough the loose soil in time to increase soil permeability.

5.Chemical control. At the seedling stage, the root system can be irrigated with Puli water, which can effectively prevent Puli water. After planting slow seedlings, the roots can be filled with Oxazalin, which has a good control effect on Fusarium wilt, and spraying amicida suspension and ethephon EC before the outbreak of the epidemic has a better control effect.

In the hot and rainy summer season, it is best to sprinkle copper sulfate before watering the peppers, and then water them to prevent pepper wilt and stem base rot. Root rot can be irrigated in the early and early stages, and diseased plants can be uprooted in time when found in the middle of growth.

The serious imbalance of the proportion of nutrients in the soil, due to the particularly high yield of vegetables such as peppers, the highest yield per mu can reach more than tens of thousands of catties, and the nutrients absorbed and demanded by crops with high yields are more, and a large number of nutrients in the soil are taken away with the harvesting of peppers. In order to ensure the continuous high and stable yield of crops, the nutrients taken away, we have timely supplementation through fertilization, but we only pay attention to the application of chemical fertilizers, and the nutrients of chemical fertilizers are relatively single, so that there will be a lack of individual nutrients in the soil, resulting in soil nutrient imbalance, according to the law of minimum nutrients of crops, only what nutrients are missing in the soil, what nutrients are supplemented, so that crops can obtain stable yields.

It is most likely because the soil moisture is too high, or it is also due to the salinization of the soil.

It is very likely that there is a problem with the variety, or there is a problem with the soil, which leads to the situation that it is easy to die, so be sure to choose the right variety.

1. Soil salinization, high degree of acidification, due to the production of eggplant vegetables such as peppers for many years, the amount of chemical fertilizer application has increased year by year, such as Shandong Shouguang only more than 300 kilograms of base fertilizer input, the utilization rate of chemical fertilizer is only about 30%, a large number of acidic fertilizers are left in the soil, chemical fertilizer itself is also a kind of salt, which is bound to cause soil acidification, salinization degree increases, and the pH value of some old greenhouses has reached 3-5. The pH value of the normal growth of vegetables such as peppers should be between, can you imagine how peppers can grow normally in such an acidic environment, and can there be no dead seedlings?

2. The proportion of biological flora in the soil is out of balance, that is to say, due to years of production, there will be fewer and fewer beneficial microorganisms in the soil, such as photosynthetic bacteria, phosphate-solubilizing bacteria, and beneficial insects such as earthworms, and more harmful microorganisms such as Fusarium, harmful insects such as ground tigers and grubs. This will inevitably lead to the aggravation of some heavy crop diseases and insect pests.
