Why does spinach die and rot roots after rain?

There are several reasons why spinach will die and rot its roots after rain:

1.Soil moisture is too high: the roots of spinach need to breathe oxygen for aerobic respiration, if the soil moisture is too high, the permeability is reduced, the roots can not carry out normal aerobic respiration, enter anaerobic respiration, the anaerobic respiration products are mainly ethanol or lactic acid, the root system can not continue to develop, causing corrosion to the root system, resulting in the phenomenon of "rooting".

2.Seedling diseases: such as blight, which will appear in many crops at the seedling stage, the symptoms are root rot, the base of the stem into a scar-like shape, the upper lodging yellow, until dry up and die.

3.Heavy cropping plots: the content of sclerotinia in the soil is high, and the spores of the fungus will spread rapidly through running water, and if you continue to grow spinach, the probability of infection with blight is high, and it will be accompanied by the occurrence of cataplexy.

The above is the reason why spinach dies and rots after rain, I hope it will help you.

Rain causes spinach to soak in water, so that the roots will produce alcohol, so that the roots rot, pay attention to drainage, the humidity is easy to rot the roots, under normal circumstances, it is possible to drain the water in time, immediately drain the water, and then irrigate the roots with the dry farmer "Root Shangya".

Spinach needs good air permeability, soft sandy soil is better, spinach can not accumulate water, water is easy to rot roots, after rain the soil drainage is not good, caused by too much water rotten roots.

It is very likely that this is a problem with the variety, and it may be a problem with the fertilizer applied. This situation is actually very dangerous and can lead to the loss of your money.

The possible reasons why spinach dies as soon as the seedlings emerge are: overwatering, seeds not germinating, wrong fertilization, etc.

It may be due to environmental reasons, it may be cold, or it may be hot.

The seed shell of spinach seeds is relatively thick, and if it is sown directly, the germination is slow, and it is not easy to gather seedlings, so it is generally necessary to soak the seeds in advance and promote germination.

After soaking, the seeds are usually soaked with pesticides to kill harmful bacteria, improve the antiviral ability of the seeds, and also make the seedlings more robust after emergence. If this is not done, there is a high risk that the seedlings will be affected or injured by residual pests and diseases in the soil, resulting in the phenomenon of dead seedlings.

1.Too much water, causing root injury, do not grow, spinach in the early stage of watering pay attention to watering. 2. Insufficient fertilizer and nutrition can't keep up. 3. Soil problems, soil compaction, at this time it is necessary to loosen the soil. 4. The soil is too dry.

Spinach, like other crops, should also be topdressed according to different growth periods under the condition of maintaining base fertilizer to promote growth. However, in the seedling stage, the demand for fertilizer for spinach is not strong, and if a large amount of top dressing is carried out, it is easy to produce fertilizer damage and burn seedlings.

1. The planting of virtual jujube is too dense. As a result, the spinach cavity Zheng Jian snatched the fertilizer seriously, and the root system was not developed, and it was easy to die after the winter.

2. The selection of planting period is inappropriate. To grasp the number of spinach leaves, too much or too little is not enough, and the average temperature of the day is 18 degrees.

3. The amount of water is not well controlled. Too much watering can easily lead to freezing on the surface, which hinders the breathing of seedlings, too little watering has cracks in the ground, and the roots of seedlings are prone to frostbite, so watering should be based on watering that can completely penetrate down.

Spinach: also known as Persian cabbage, red root cabbage, parrot cabbage, etc., belongs to the genus Spinach in the Chenopinoa family, an annual herbaceous plant. The plant can be up to 1 m tall, with conical, reddish-tingting, less white, halberd-shaped to ovate, bright green, entire-edged or with a few tooth-like lobes.

There are many types of spinach, which can be divided into two varieties, thorny and thornless, according to the seed form. Spinach is native to Iran and is commonly cultivated in China as one of the most common vegetables.

When the spinach has rotten roots, it is necessary to prune off the rotten root system and spray the plant roots with a 500-fold diluted mold nail cream pesticide; It can also be repotted to change the soil in which the plant grows; After spinach rots roots, loosen the soil in which it grows to ensure that there is enough oxygen in the soil, and grow spinach in an environment with good air circulation.

Spinach is the most common food on our dinner table, so what to do with rotten roots after spinach emerges, we have to cut off the rotten roots, and use 500 times diluted molew nail cream pesticide to spray the roots of the plant until they are cured, or soak the roots in a 150 times diluted solution of oxazine, and it can recover after a week.

If it is a potted spinach, dig it out of the pot, cut off the rotten roots and wash it with disinfectant water, choose garden soil for planting, and there should be about 7 small holes at the bottom of the pot, which is convenient for the soil and external ventilation; Do not water after changing pots to keep the soil slightly dry.

When the oxygen in the soil is depleted, the spinach will be deprived of oxygen, resulting in root rot. It is necessary to use tools to renovate all the soil and do the loose work appropriately; You can also sprinkle a few small pieces of gravel in the soil to increase air permeability and ensure that there is enough oxygen in the soil.

When spinach has rotten roots, it is necessary to investigate whether the plant grows in a closed environment; If the air is not circulated, the excavated plants and the outside air will not be able to be exchanged well, which will also lead to root rot. It is necessary to grow spinach in an air-ventilated environment to enhance the respiration of the plant and prevent root rot.

After continuous rainfall, if it suddenly turns sunny, in order to avoid physiological water loss of spinach and cause the leaves to shrink, we should water it in the morning and evening to cool down. When the spinach enters the vigorous growth period, the plant needs a lot of water, so we should irrigate it in time according to the soil moisture.

Spinach is one of the most common vegetables in our daily life, and there is a certain planting area in various parts of our country. Spinach is a vegetable with a short growth period, fast growth rate and long continuous harvest period, on the other hand, spinach has relatively few pests and diseases in the growth process, even if it is not sprayed, it can generally grow fast and good! <>

The bottom fertilizer can be sufficient before planting, and there is no need for too much fertilizer and water in the later stage, sufficient light helps to grow, the seed coat of spinach seeds is thick and hard, if it is directly sown into the soil without soaking water treatment, there will be slow germination and slow seedling, therefore, in order to promote spinach after sowing faster, lead quietly guess more satiety water absorption and germination, faster and more uniform seedlings, you can soak it in water Spinach seeds are being sown, after the emergence of seedlings during 1 leaf seedling 1 time, 3 leaves before the beginning of the seedling, so as to remove small seedlings, weak seedlings, Diseased seedlings, miscellaneous seedlings, to dense and thin, 70 100 plants per square meter when the seedlings are fixed, which can prevent spinach seedlings from being dwarf, as well as the prevention and control of pests and diseases, the common pests in the spinach seedling stage are cabbage worms, aphids, ape leaf insects, ground tigers. <>

During the whole growth period of spinach, there must be very sufficient water to achieve the rapid growth of leaves, especially in the high temperature season, it must not be too dry, and when there is a lack of water, the taste of the leaves will be bitter. Generally, it is necessary to water once every three or four days, the root system of spinach is relatively deep, when watering, can not be watered with large water, in order to prevent the root system from being harmed, soft rot occurs, the field humidity is large, and the leaves are also prone to downy mildew, so it is necessary to water frequently with small water, water evenly, and avoid high temperature watering at noon. Eating more spinach is also good for health, which can be a good supplement to iron luck, and eating more is beneficial.

<> spinach dies after emergence, it may be due to the wrong variety selection, planting cold-tolerant varieties in summer, heat-tolerant varieties in winter, or planting spinach without disinfecting the soil and seeds, or it may be that the water and fertilizer for spinach are not controlled during maintenance, resulting in water rotting and death of the plants.

1. Breed problem.

Spinach dies after emergence, possibly as a variety. Spinach is divided into two varieties, cold-tolerant varieties and heat-tolerant varieties, where cold-tolerant varieties are suitable for planting in October every year, while heat-tolerant varieties are suitable for planting in summer, if you choose the wrong choice when planting, it will cause spinach to die after emergence.

2. Improper planting.

Spinach dies after emergence, and the limbs are scattered, which may be due to improper planting. In the process of raising seedlings, the seedling soil needs to be disinfected and sterilized, to avoid the bacteria and pests in the soil to harm the development and growth of seeds, and also need to soak and disinfect spinach seeds to improve their disease resistance.

3. Wrong fertilization.

Spinach dies after emergence, which may also be due to improper fertilization. Spinach seedlings are fragile and cannot absorb too much nutrients, so too much fertilizer at this time will cause the seedlings to die due to fertilizer damage, and the use of raw fertilizer or thick fertilizer during fertilization will also cause spinach to be infected by bacteria in the fertilizer and die.

4. Overwatering.

When cultivating spinach seedlings, the water provided for them is excessive, which leads to the death of spinach seedlings. Because when spinach is in the seedling stage, its root system is not fully mature and cannot absorb too much water, and the frequent supply of water for spinach at this time will cause the roots to rot and die.

Hello, I am the master of the field of life encyclopedia, and now I will answer for you: Hello, spinach seedlings rotten roots 1, chemical control: soil disinfection, fertilization can be used with oxazine soil treatment agent, per mu according to the manufacturer's recommended use method and dosage, kill most of the rhizoctonia in the soil; It is also possible to spray 30% nail cream after spinach emerges.

Soil disinfection was carried out with aqueous agent of oxamycolin, with an interval of 7 days, and the drug was applied twice to reduce the incidence of seedling stage; 2. Physical control: When treating the soil, add coarse sand or coal ash to the soil in an appropriate amount, the purpose is to increase the soil particle void, increase permeability, and reduce the occurrence of dead seedlings and rotten roots when the humidity is high. When sowing spinach in spring and winter, you can sprinkle a layer of plant ash on the ground.

3. Agricultural prevention and control: choose stubble plots for planting, and you can choose plots with cereal crops on the stubble for sowing. If you have to plant in heavy crops, you must do a good job of soil disinfection.

When the spinach has rotten roots, it is necessary to prune off the rotten root system and spray the plant roots with a 500-fold diluted mold nail cream pesticide;
