Why do snow peas bloom and grow beans, but the seedlings begin to die?

Snow peas and legumes have a high nutritional value. They are all vegetables and foods that people love very much. When you grow snow peas, it is not uncommon for the beans to bloom and die.

There are several reasons for this. The first is bug-infested, because the sweet roots of snow peas are more likely to attract bugs, and the bugs will bite off the roots of snow peas. The tendon of the bitten root.

It can no longer absorb and ** nutrients to the soybean seedlings, so the soybean seedlings die. It is also possible that there is a problem with the water quality of the irrigation, and the water source is seriously polluted.

Harmful impurities in the water will cause the roots of the beans to rot, so the seedlings will die. Third, it is also possible that the fertilizer is used too much, or when the plant uses chemical fertilizer, it is too close to the roots, and the seedlings are burned. In the middle of summer, the sun is hot, the farmers are still working, and the beads drip into the dirt.

Who knew every meal was hard. For people with different cognitions, a person who grows crops is not just planting in the ground, taking root and sprouting, seedlings growing, bearing fruit, and then harvesting.

How many people know how to grow crops? There is also the issue of universities. The sorrow is known only to the harvesters themselves.

The Netherlands can tolerate a certain amount of drought at the seedling stage, which is very beneficial for root development. When the humidity is too high, it is easy to induce root rot and powdery mildew. Humidity is required for flowering.

High, too dry will lead to a reduced flowering period and severe flower and pod dropping. Therefore, snow peas must have sufficient moisture** throughout the growing season to maintain quality and quantity.

Snow peas are not waterlogged. If there is too much moisture, they are prone to rot after sowing, rot roots at the seedling stage, and get sick during growth. However, in the flowering and pod-setting stage of Phaseolus vulgaris, root rot is most likely to occur, which can cause a large number of Dutch beans to die, and the root rot of Phaseolus vulgaris is mainly to damage roots or rhizomes.

The lower leaves of the diseased plant turn yellow first and develop upwards, causing the plant to turn yellow and wilt if you pull out a dead snow pea.

Now planted in the plant, you will find that its taproot and lateral roots are black, and if you dig out the black roots, you will find that the inside is all brown or reddish-brown. The base of the plant with mild disease overflows or depressions and turns brown, and the cortex of the diseased part decays, making the plant dwarf, with small leaves, light green, few pods, and low yield.

This can only indicate that the seedlings have been infested at the roots, and because of this, they will wilt.

It must have been caused by pests and diseases. You certainly didn't apply pesticides to them. Therefore, pesticides should be applied every day at the beginning of planting.

It is likely that his roots have been infested, or it may have been due to problems with the quality of the irrigation water, or it could have been due to excessive use of chemical fertilizers.

<> dead snow pea seedlings are usually caused by pests and diseases. Taking root rot as an example, it usually occurs during the seedling period of snow peas, generally in the rainy season, or when the rainfall is relatively large, it is caused by bacterial infection of snow peas, the disease mainly harms the roots of the plant, so that the whole plant loses water and dies fundamentally.

Hello dear, there are many reasons why snow pea seedlings cannot grow, the most common reason is lack of nutrients, such as lack of nutrients such as nitrogen, phosphorus, and potassium; In addition, it can also be used for water shortage, and when plants lack water, the leaves will turn yellow and shrink; In addition, it may also be pests and diseases, and plants will be attacked by pests and diseases, which will cause the leaves to turn yellow and shrivel; Finally, it may be that the temperature is too low, and the leaves will turn yellow and shrink in the low temperature environment.

<> the reasons why snow pea does not bear fruit after flowering are as follows: early partial application of nitrogen fertilizer, which causes plant growth and limited flower bud differentiation; The planting density is too large, and the light is insufficient; The weather is excessively dry, the amount of water in the soil evaporates a lot, etc. Prevention and control methods:

At the same time as early application of nitrogen fertilizer, it is necessary to apply phosphorus and potassium fertilizer to promote flower bud differentiation and flower organ development. Keep proper spacing when planting, and replenish water in time when there is a shortage of water to prevent snow peas from running out of water due to excessive drought. Rotten.

Snow peas do not produce beans when they bloom, it may be caused by excessive nitrogen fertilizer application in the early stage of its growth, snow peas are a long-day plant, if the light is insufficient, it may also bloom without beans, and it may be caused by insufficient nutrients, and if the cultivation density is too high, the growth space of snow peas will be insufficient, so it will not produce beans.

1. Improper fertilization

In the early stage of snow pea growth, if the nitrogen fertilizer is applied excessively, then its stems and leaves will be too vigorous, so that the differentiation and growth of its flower buds will be inhibited, and then the snow pea will not be able to produce beans.

2. Insufficient light

Snow pea belongs to a long-day plant, its growth needs sufficient light exposure, if the light is insufficient, then it will appear not to produce beans, when the snow pea is cultivated and cultivated, it should be irradiated with light that disturbs the sleepy feet, which is conducive to its photosynthesis.

3. Insufficient moisture

Snow peas have more demand for water, in its flowering and fruiting period, if the water is too little and the humidity is not enough, then it will also appear that it does not produce beans, so lead shirt in the dry season, we should often water snow peas, pay attention not to let the soil have water to produce, so as not to rot the snow peas.

4. The density is too high

When planting snow peas, if the density is too high, then the growth space of snow peas will be insufficient, and the nutrients in the soil will not meet the growth needs of snow peas, and it will also affect its internal ventilation, so it will not produce beans.

Snow peas do not produce beans when they bloom, it may be caused by excessive nitrogen fertilizer application in the early stage of its growth, snow peas are a long-day plant, if the light is insufficient, it may also bloom without beans, and it may be caused by insufficient nutrients, and if the cultivation density is too high, the growth space of snow peas will be insufficient, so it will not produce beans.

1. Improper fertilization

Snow peas do not produce beans when flowering, may be caused by improper fertilization, in the early stage of snow pea growth, if the nitrogen fertilizer is applied too much, then its stems and leaves will be too vigorous, so that the differentiation and growth of its flower buds will be inhibited, and then it will make snow peas unable to produce beans.

2. Insufficient light

Snow peas belong to a kind of long-day plant, its growth needs sufficient light, if the light is insufficient, then it will not produce beans, so when cultivating and breeding snow peas, it is necessary to let it have enough light to irradiate Huaiju, which is conducive to its photosynthesis.

3. Insufficient moisture

Snow peas have more demand for water, in its flowering and fruiting period, if the water is too little and the humidity is not enough, then it will also appear that it does not produce beans, so in the dry season, it is necessary to water snow peas frequently, pay attention not to let the soil have water to produce, so as not to rot the roots of snow peas.

4. The density is too high

When planting snow peas, if the density is too high, then the growth space of snow peas will be insufficient, and the nutrients in the soil will not meet the growth needs of snow peas, and it will also affect its internal ventilation lead reform, so it will not produce beans.

There may be the following reasons for your inquiry: 1. Early partial application of nitrogen fertilizer is absolutely inadequate. Partial application of nitrogen fertilizer is easy to cause plant growth, and the differentiation of flower buds is limited!

2. The planting density is too large and the light is insufficient. Snow peas have strong requirements for light intensity, if the plant density is too large and the light is insufficient, it is easy to delay the flowering of the plant, resulting in flower drop! 3. The weather is excessively dry, and the evaporation of the land is large, which will cause drought and will also make snow peas fall into flowers.

<> there are many reasons for the death of snow pea seedlings, and the phenomenon of dead seedlings caused by different reasons should be scientifically applied with different drugs, taking root rot as an example, it is generally possible to irrigate the roots with drugs such as methyl frost and chlorethoxin or copper preparations, or spray with drugs such as carbendazim.

Introduction: China is a big grain country, the grain industry ranks first in the world, every year to foreign countries a lot of grain, including corn and wheat and rice as the main export grain, in fact, China's grain industry has many kinds, including bean food is also countless, all kinds of mung bean, soybean soybean food is not only rich in nutrition, but also welcomed by people. Today I will take you to understand some problems of snow peas.

1. Snow peas.

He Lan bean is a legume plant, the reason why snow peas are called snow peas, is not like its name, it is said to be produced in Henan, but because various plants were introduced to the country by the Dutch, so everyone calls it snow peas. Snow peas to the shape of flat leaves, therefore, in many places also called lentils, its nutritional value is very high, in the use of not to eat the beans of the snow pea seed, but to eat the whole whole, snow peas used to stir-fry very delicious, and has a high nutritional value. <>

2. The growth environment of the Netherlands.

Snow peas are a very light-loving crop, and if you check the light hours of snow peas, they may shorten their flowering time and produce fruit earlier. However, although snow peas like light but not suitable for high temperatures, therefore, suitable for cultivation in the alternation of spring and summer, in the growth process, snow peas need more water, if the soil moisture is insufficient, it will greatly delay its emergence period, therefore, after sowing, should be watered frequently, so that the plant quickly germinates and takes root. <>

3. Pest control.

Snow pea blight is a very serious disease of snow peas, and the disease occurs in many places, is a very common plant disease, often causes a large area of snow peas to die, has a great impact on plant growth, the disease mainly affects the roots of crops, resulting in crop death, therefore, when planting snow peas, you should understand its disease characteristics, and take more precautions, if necessary, spray some drugs to ** the disease.

Blight occurs in both protected areas and open fields, with severe disease in open fields and serious diseases in individual sheds, often causing patches of dead seedlings and significantly affecting production. At the beginning, it produces yellow-brown necrotic spots at the base of the rhizome, and later becomes nearly oval to irregular necrotic spots, and further develops up and down, so that the rhizome and even the root system are all infected. At the same time, the leaves of the diseased seedlings gradually die and dry up from the bottom to the top, and finally the whole seedling dies.

Pathogenesis] The pathogen overwinters with the diseased residue with hyphae and sclerotia in the soil or on the diseased tissue.

There will be some necrotic spots on the leaves, and it will also cause the plant to die gradually, and it can occur in any part, which will eventually seriously affect the yield of the plant.

At the beginning, it produces yellowish-brown necrotic spots at the base of the rhizome, which slowly turn into nearly oval to irregular spots, and then develop until the rhizome and even the root system are completely infected.

The symptoms of snow pea blight are that it will cause the seedlings of snow peas to die in pieces, affecting the yield of snow peas.

Symptoms of blight: After the seedlings are lignified, white hairy, filamentous or white spider webs appear on the stems. The root cortex and fine root tissues rot, the stems and leaves are yellow, dry and die, but do not lodging.

Pathogen: The pathogen is a basidiomycete fungus, whose scientific name is rhizoctonia solani.
