Too much fertilizer, especially when there is too much basal fertilizer and lack of phosphorus and potassium fertilizer, it is very easy to cause the leaves to turn yellow, which is mainly manifested as leaf hypertrophy, most of the leaves are uneven, and the yellow leaves slowly turn yellow and fall down, and the leaf tips become dry when it is more serious, and even all the leaves turn yellow. In this case, fertilizer should be applied immediately, the amount of sprinkling should be increased, and the fertilizer should be discharged from the drainage hole, or directly poured into the pot, remove a part of the old soil, and wash the soil with water, replace a part of the new cultivation soil, and then plant the plant into the pot again.
Middle. Pea sprouts.
In the planting process, especially during the stacking and tooth promotion period, it is very easy to produce rotten seeds, and the production and manufacturing must strictly control the amount of watering and ambient temperature, and the water flow is too much, especially in the case of continuous high temperature, high and low temperature, it is very easy to cause rotten seeds and rotten buds. In addition, the seedling tray should be cleaned and disinfected strictly, and as mentioned earlier, appropriate detergent or bleach can be added to the water. In the supervision process, the rotten seeds are removed immediately, and the rotten seeds gradually turn gray-black, and slowly rot into a batter, which is very easy to distinguish from normal seeds.
Brown spot disease. In the early stage of production, the pathogen is accompanied by the sprayed water in the internal structure of the whole seedling tray and the middle of the seedling tray to spread rapidly, and the whole bed of pea seedlings can be destroyed when it is more serious. At the onset of the disease, the rhizome of the diseased seedling becomes dark brown, the white roots are reduced, the seed coat is also browned, and the growth and development of the plant is stunted.
The prevention method is to use excellent varieties, strict disinfection and sterilization when soaking seeds, strict disinfection and sterilization of seedling trays, and use bleach or potassium permanganate after the applied seedling trays are cleaned and tidy.
Liquid bubble immersion disinfection and sterilization. Remove diseased seedlings immediately.
In fact, the more critical factor in this situation is that lentil seedlings are infected with basal rot, which is also called pea seedling bacterial wilt in some areas. The pest and disease occurs in the pea seedling stage, which is the key to damage the seeds and seedlings of lentils, and the seeds can cause seed rot when they germinate. After the seedlings are sick, their growth and development are stunted and they fall or slowly wither, and light brown spider mold will grow when the environmental humidity is too high.
Insufficient fertilizer, especially for long-term unapplied basal fertilizer or unpotted soil, the nutrient content of nutrients in the soil is lacking, resulting in weak branches, thin and yellow leaves, it is necessary to pour the pot immediately, slip off the plant, replace a larger pot, put in a new soft and rich shaping soil, and plant it again. After watering permeability, put it in a semi-dark place to slow down the roots. After its repair, growth and development, apply a thinner fertilizer or compound organic fertilizer.

You can give priority to checking whether the apprentice lacks fertilizer and whether the land is dry and cracked. Secondly, it is necessary to check whether the pea seedlings have diseases. If you want to solve these problems, you must first find the root cause of the problem, solve it from the root, these problems, if it is because of the land, then you can choose to fertilize and water or weed to change the land, if it is the cause of the disease, then you can choose to kill him insecticidal and weeding or other.

Avoid continuous cropping, choose cold-tolerant varieties, and deep ploughing and land preparation, but also strengthen management, to remove diseased parts, so as to prevent infectious diseases.

What should I do with the seedlings that I asked about flowering? Is it fertilizer and water management?
Hello, yes, follow the methods above.
Don't you want to remove the flowers?
Hello, to remove. It is an abnormal phenomenon for pea seedlings to bloom and bear fruit at a very young age, which is generally caused by poor management to enter the reproductive growth stage prematurely. At this time, you should pay attention to sufficient light, and the watering should be dry and thorough, so as to avoid overgrowth.
Fertilization is mainly based on basal fertilizer, and more phosphorus and potassium fertilizers should be applied to imitate the bureau, and nitrogen fertilizers can be basically not applied. From the beginning of the vigorous growth period of branches and leaves, apply decomposed organic fertilizer once every 10 days or so. When the plant height reaches 30 40 cm, insert a bamboo pole in the potting soil to make a number of macro covers, pull pea seedlings to climb, and pay attention to the uniform distribution of stems and leaves.

Summary. The reason is lack of management, infection with diseases.
The reason is lack of management, infection with diseases.
Dead pea seedlings are caused by heavy planting. Strengthen fertilizer and water management, and prevent and control the occurrence of pests and diseases in a timely manner. The main reason for the death of pea seedlings is lack of management.
Sowing too shallowly or watering and fertilizing to wash away the soil, not covering the soil in time, resulting in exposed seeds and sunburn after emergence; The root system is artificially loosened on the erection line and the plant grows to a certain height by the wind after the erection is launched, and the root system is broken and dies. In order to ensure the implementation of the work tasks, a friendly supervision and guidance working group was set up to supervise, inspect and guide the epidemic prevention work. In carrying out their work, the township and town animal supervision offices should truly ensure that the town does not miss the village, the village does not miss the good letter to refer to the household, and the household does not miss the livestock (poultry).
It may be that the soil is not sufficiently fertile and watery.
After the root system of the man-made pine shirt is moved and the frame is put on the line, the plant grows to a certain height and is cracked by the wind, and the root system is broken and died. The annual planting of vegetable peas in the same plot can not interrupt the infection cycle of pests and diseases, resulting in serious seedling death, and the straw is piled up indiscriminately after the pea is harvested, and if it is not treated in time, it will also cause the seedlings to die in the next year. There are many, chaotic and miscellaneous pea seeds in the market, and many varieties that are very susceptible to diseases have entered the market without any experiments, which is one of the important reasons for the death of pea seedlings.
In addition, sowing too shallow or watering and fertilizing will wash away the covering soil, and the soil will not be covered in time, resulting in the seeds being exposed, and the seedlings will be directly killed by strong light. Soil salinization causes a lack of dead seedlings, and underground insects cause collapse. The main reason is that pea seedlings are infected with basal rot, and some places are called pea seedling blight.
The disease occurs in the seedling stage of peas, mainly harms the seeds and seedlings of peas, and the seeds will cause seed rot before emergence. When the seedlings are diseased, they grow slowly and fold or die gradually, and when the humidity is high, light brown arachnoid mold grows.
