Why do planted peppers die seedlings and are there any remedies for not

Peppers will die seedlings for the following reasons, and there are remedies:

1. Bacterial infection, such as bacterial wilt.

The disease mostly starts to wilt from the top leaves of the branches, and wilts and wilts at the same time with the whole leaf of the plant, and the course of the disease is short. The symptoms of the diseased stem were not obvious, the vascular bundles of the longitudinal stem turned brown, and milky white mucus overflow could be seen in the cross-sectional moisturization.

2. It is a fungal disease, and there are three main kinds of blight, blight and sclerotinia sclerotinia disease.

At the beginning of the onset of Fusarium wilt, a large number of lower leaves fell off, and the cortex at the base of the stem in contact with the ground was water-stained and decayed, and the aboveground stems and leaves withered rapidly.

Blight can occur throughout the growth period of peppers, and is most vulnerable after fruit set. When the adult plant is damaged, the diseased part forms a long strip-shaped spot, the junction between the diseased and the healthy is obvious, the lesion is sunken or slightly shrunken, and the leaves of the diseased plant wilt and fall off the leaves, resulting in death.

Sclerotinia sclerotinia is the root or fork of the branch, when the humidity is high, the disease grows white mycelium, and the black rat fecal-like sclerotia can grow in the later stage, and finally the plant dies.

Among them, the incidence of epidemic disease is the highest, accounting for about 70% of the dead field, this disease occurs quickly, especially after high temperature watering, it can be susceptible to a large area in a few hours, not only seedlings can be susceptible, but also the stems, leaves, and fruits of adult plants can be susceptible to disease, and the transmission speed is also faster, and the harm is greater;

The second is root rot, accounting for about 20% of the dead fields, generally after hanging fruit begins to wilt, the taproot occurs brown lesions, the root bark is easy to peel off, so that the pepper fruit can not mature normally, root rot has a long course of disease, difficult to find in the early stage, once it is found too late, so early prevention is crucial;

The proportion of bacterial wilt and wilt is small, but bacterial wilt is a bacterial disease that not only spreads quickly, but also has a short course of disease and rapid death, and is often devastating.

Dead black roots of peppers, caused by root disease, blight, stem base rot or blight, some of them are not rooted caused by soil or water, use spicy bar, cure the root together, the effect of pepper is good, and there is a lot of pinduo.

Water, soil, fertilizer, sunlight. Look at which one is missing, pepper seedlings are very easy to grow, how can they die!

If the pepper seedlings are wilting, try spraying brassin.

Brasssin, also known as brassinolide, is a new type of plant endogenous hormone, is recognized as a high-efficiency, broad-spectrum, non-toxic plant growth regulator, strong penetration, fast absorption, at very low concentrations, that can significantly increase the growth of plant nutrients and promote pollination. It can effectively increase chlorophyll.

content, improve the efficiency of photosynthesis, promote root and seedling growth, flower and fruit preservation; Improve the resistance of crops to cold, drought, salinity and alkali, and significantly reduce the occurrence of diseases; And it can significantly alleviate the occurrence of pesticide damage, make crops quickly resume growth, and can eliminate disease spots.

Brassinolide is a new type of green plant growth regulator, which is treated by soaking with suitable concentration of brassinolide and spraying on stems and leaves. It can promote the growth of vegetables, melons, fruits and other crops, improve quality, increase yield, bright color and thicker leaves. It can also make the leaf picking time of tea earlier, and can also make melons and fruits have higher sugar content, larger individuals, higher yields, and more resistant to storage.

The plant growth regulator on the pesticide market is synthesized sodium nitrate.

and brassin. In practical application, the naturally extracted brassins have the best quality and better comprehensive economic benefits, and can be welcomed and applied by farmers. Regardless of which type of plant hormone it belongs to, it is harmless to humans and animals, and the normal use dose is very effective.

Natural brassins can be widely used in food crops.

For example, rice, wheat, and potatoes can generally increase the yield by about 10%; It is applied to a variety of cash crops.

If trees, vegetables, strawberries, melons and fruits, cotton and linen.

Flowers, etc., can generally increase the yield by 10 to 20%, and the high can reach 30%, and can significantly improve the quality, increase the sugar and fruit weight, and increase the flowery flowers. At the same time, it can also improve the drought resistance and cold resistance of crops, and alleviate the symptoms of crop pests and diseases, pests, pesticide damage, fertilizer damage, and frost damage.

It is recognized by the academic community as a class 6 plant hormone. It can be used for field crops, fruits, vegetables, flowers, etc. It has multiple functions such as strong rooting, promoting growth, raising seedlings, strengthening seedlings, protecting seedlings, turning yellow leaves into green leaves, promoting the expansion and early maturity of fruit fruits, reducing diseases and alleviating pesticide damage, coordinating nutritional balance, drought and cold resistance, and enhancing crop stress resistance.

The first aid effect on the phenomenon of dead seedlings, rotten roots, and cataplexy caused by heavy stubble, disease, pesticide damage, frost damage, etc., is obvious, and the application is obvious for 12 to 24 hours, and the vitality is quickly restored. It is suitable for grain crops, cash crops, vegetables and fruits, etc., to promote growth, make fruit bulking agent, and increase yield.

The ratio of brassinin to water should be judged according to the concentration of brassin. The concentration of brassin, every 5 to 8 milliliters needs to be mixed with 30 catties of water. The concentration of Yuntai, per 15 ml of brassin, is mixed with 30 catties of water.

Reasonable use can have a better effect. Brassin is a highly effective, non-toxic growth regulator that promotes better plant growth even at low concentrations.

Brassin can not only enhance the stress resistance of seedlings, which is conducive to slowing down seedlings, and brassinin can also alleviate pesticide damage and fertilizer damage, and can also promote the development of basal chain into the root system of seedlings. In short, brassinin has many benefits, and spraying brassinin after transplanting pepper seedlings can promote high yield and high quality of pepper.

The control agent can be fluorinylurea, manganese-zinc, oxazolidinone and its compound preparations, such as DuPont-Jikuaijing, Yibao, enoylmorpholine + pyraclostrobin, etc. Generally once every 7-10 days, peppers should be treated as soon as possible after bacterial wilt. At the beginning of the disease, 77% kocide wettable powder 800 times can be sprayed continuously 3 times, with an interval of 5-7 days.

When bacterial wilt occurs in peppers, it is usually accompanied by insect infestation and is treated with insecticides, and soils with high humidity are susceptible to this disease.

In the early stage of bacterial wilt, the main damage is to the branches and leaves. At first, the branches and leaves of the diseased part wilted, and gradually spread to the whole plant, the color of the whole plant became light, the leaves were burnt yellow, and the distinctive feature was that the appearance of the stem of the diseased plant was not obvious, and the vascular bundles turned brown when the diseased plants were dissected, and when the slices were sliced, the milky white mucus overflowed from the vascular bundles, which was different from blight. As for the problem that peppers are prone to die in summer, this is mainly due to the high temperature and rain in summer, and the drought is caused.

Moreover, as a shallow root system, pepper is prone to stem rot, wilt, root rot, etc.

Peppers are harmed by high or low temperatures, when peppers are harmed by high temperatures, they should be watered to cool down at night, and shade nets should be built in places where conditions permit, shade the sun, and reduce the ground temperature of peppers. When the temperature is low, tie up the greenhouse and raise the temperature. Root burning caused by improper fertilization For root burning caused by the increase in fertilizer concentration in the soil after the application of chemical fertilizer without watering in the case of low soil moisture content, it is necessary to water to reduce the fertilizer concentration in the soil, restore the growth of plants as soon as possible, and reduce losses.

To sum up, when planting peppers, it is necessary to plough the soil in advance, turn over the soil, and expose it to the sun, which can kill most of the germs in the soil. Peppers should not be cropped continuously, and the soil before crop rotation should not be Solanaceae. At the same time, the seeds should be disinfected before seedlings, and the seeds can be soaked in 1% copper sulfate solution for 20 minutes, which can destroy the germs on the seeds.

Cayenne peppers should be treated as early as possible, sprayed on cloudy or sunny days. When it rains, it should be sprayed again within 6 hours.

Peppers are particularly easy to die, mainly related to soil deterioration, and will reduce a large part of the soil after conditioning the soil, but in addition to changing the soil, we still have to use medicine, because after all, there are germs in the soil. At present, there are two major soil-borne diseases of pepper dead trees, one is canker disease, the other is medullary necrosis, and both of them are bacterial, once these two diseases occur, they can multiply and spread in the vascular bundle and will damage the phloem and xylem and then cause water and nutrients to be transported normally, and a little pepper will wilt and die. <>

Therefore, for the dead pepper trees, on the basis of soil improvement, we should also use pesticides to irrigate the roots for prevention and control. If diseased plants are found in the shed, they should be treated with pesticides as soon as possible. Since the two diseases mostly occur at the base of the stem, the sprayer nozzle can be removed and sprayed down 10 cm above the diseased part when the liquid reaches the surface.

Eggplant sclerotinia sclerotinia can be sprayed with 430 times of "gray kernel net". Eggplant stem base rot can be used to irrigate the roots with "special for wilted root rot". <>

Generally, spray once every 5-7 days. 2-3 times in a row. Generally, irrigation 1 time in the seedling stage, 1 time before a spike of fruit flowering and fruiting, irrigation 1 time every 20-30 days in the subsequent growing season can basically be well prevented, if it has happened, it should immediately stop flood irrigation, pull out serious diseased plants after irrigating roots to control the disease and then water and fertilize normally.

The implementation of crop rotation, deep ploughing and soil modification, combined with deep ploughing, increased application of organic fertilizer, phosphorus and potassium fertilizer and micro fertilizer, appropriate application of nitrogen fertilizer, improve soil structure, improve fertilizer and water retention performance, promote the development of root system, and plant health. Fully cover the mulch, strengthen aeration, adjust the temperature and air relative humidity of the greenhouse, so that the temperature is maintained at 25 30 during the day and 14 18 at night, and the relative humidity of the air is controlled below 70%, so as to facilitate the normal growth and development of eggplant, which is not conducive to the infection and development of diseases, and achieves the purpose of disease prevention and control. Pay attention to observation, find a small number of diseased leaves and fruits, immediately remove and bury deeply, find that the stem is diseased, and immediately use 200 times 70% mancozeb solution to smear the lesions and eradicate the pathogen.

It is recommended to pay attention to whether there are any borers in the roots, or if there is corruption or lesions in the roots. If there are moths, you can choose insecticides to carry out **, if there is rot in the roots, pay attention to whether there is too much rainwater accumulation in the roots.

Some insecticides can be used**. In this way, it can effectively prevent the death of peppers, and can also better help peppers to grow, which can prevent pest problems.

It is necessary to use the drug control of the blight, or the drug to improve the pepper seedlings, pay attention to the correct amount of the drug, and understand the requirements of use.

You can choose to use pesticides to solve and prevent the pest problem of peppers, and then wait until the situation of peppers has eased before fertilizing.

In the south, chili peppers are a very popular condiment vegetable, and many dishes are chili peppers, which greatly increase the appetite. Moreover, peppers are nutritious, the harvest time is long, and the yield does not disappoint, so basically every household in the countryside grows peppers in vegetable gardens. Some friends also encountered difficulties in the process of planting peppers, and the more common one is that the survival rate of transplanted pepper seedlings is not high.

What's going on? How to transplant pepper seedlings? Let's go and find out together, and after reading it, we will know it in our hearts.

In the author's hometown of Hengyang, Hunan, the peak season for transplanting pepper seedlings is around the Qingming Festival. In the past, in rural areas, basically every household sprinkled pepper seedlings and transplanted them. In recent years, most farmers have chosen to go to the market to buy this bridge pepper sapling, which is indeed much more convenient.

But when it comes to transplanting pepper seedlings, many farmers have encountered the same problem. That is to say, after transplanting pepper seedlings, the survival rate is low, and even serious death seedlings appear. What the hell is going on?

When it comes to dead chili seedlings, many farmers have seen them, but I believe that there are many reasons that lead to the dead seedlings of chili peppers. Specifically, it can be summarized as follows.

The roots of pepper seedlings are destroyed. The time for transplanting pepper seedlings is relatively wide, and it can be transplanted up to the day before flowering at the latest. However, if you do not pour water on the seedlings in advance, or if you do not do the same thing in the process of collecting the seedlings, the roots of the pepper seedlings will be lost, and it will be more difficult to delay the seedlings after transplantation, and if the root damage is severe, the seedlings may die.

In addition, if unripe farm fertilizer is applied in the soil, it is easy to produce pests and diseases such as maggots, earthworms, needleworms, root-knot nematodes and other pests, which will damage the roots of pepper seedlings and affect the survival rate.

A certain transplantation method of pepper is not suitable. Pepper seedlings are still very adaptable and usually relieve the seedlings quickly unless there is a big sun after transplanting. However, if there is persistent hot and sunny weather on a rainy day or after transplanting, but the pepper seedlings are not shaded, the pepper seedlings will not survive easily and will be killed by the sun.

Therefore, transplanting pepper seedlings is usually done in the morning on a sunny day, so remember not to transplant during the rainy season. Also, after transplanting pepper seedlings, remember to pour water once to delay the growth of the seedlings. However, you should not water the pepper seedlings too much at one time, and you should not let the flood water fill them, and you should water them frequently.

Otherwise, the pepper will take root and sprout, causing the sapling to die. Mori Meng.

Lack of water: When cultivating pepper seedlings, it is found that the soil is dry and should be replenished in time. 2. Poor soil:

Alkaline soils and clay clay clay can cause pepper roots to be unable to breathe, and ferrous sulfate can be applied to the soil. 3. Insufficient fertilization: apply a stupid rotten organic fertilizer to pepper seedlings every 15-20 days.

4. Infectious diseases: water potassium permanganate solution or chlorothalonil suspension to the soil.
