How to save the vegetable seedlings? The vegetable seedlings are vigorous, thin and long, and what s

How to improve it: Vegetable seedlings are generally long-day plants, and of course they grow more vigorously when they see more sunlight. Balcony planting, another reason for the growth is that the planting density is large, and it will also grow.

The others continue to be long. Although the east-facing balcony can be exposed to sunlight, after all, the intensity of sunlight in the morning is relatively weak. Environmental limitations, there is really no way anymore.

Unlike vegetable patches in the countryside, which can be exposed to light for a long time. In addition, it is not known whether it is a fruit or a stem and leaf. The density of vegetables that eat fruits is greater than that of stems and leaves.

Supplemental lighting can be supplemented with lights, but the investment is too large to be cost-effective. It is more cost-effective to reduce the cultivation density. Follow-up:

Eat the fruit of the cucumber loofah beans are very good and strong, the vine has buds, on the green vegetables grow, others say that my vegetables are not sunny enough, and then I moved the vegetables to the roof, the sun is poisonous, one day on my Shanghai green radish seedlings cherry tomatoes.

It's all sunburned! I don't sow much, only two or three in a pot. But the water spinach grows very well...

Should I move the roof in the morning, move it down at noon, and move it up again in the evening? : That's too much trouble.

Open the windows and ventilate them. Vegetable seedlings can withstand strong sunlight exposure after training. It is unrealistic to move pots every day, in case one day it is delayed because of something, and the whole army will be wiped out.

If you can move it, it can also be used effectively by supplementing the lights at night. But it's more troublesome to move around. The good growth of cucumbers proves that just like vegetable farmers grow vegetables in greenhouses, increasing ventilation can alleviate the growth of cucumbers.

Follow-up: I can't tell you about my windows, floor-to-ceiling windows.

There is no glass and is a stainless steel railing of Ann.

Ventilation is definitely enough, but what about the lighting? I can't even find the reason, the sunflower sunflower is blooming, if it is not suitable for growing sea greens and lettuce now, then the cabbage is planted now, and it is the same. It's weird.

Your balcony environment is actually similar to the open air. There is no need for lighting in such an environment.

It's not a matter of lighting and ventilation. The last one may only be found in density. Arrange the tall plants in the back and the low ones in the front, and plant them not too densely.

See how. As you said, it's really weird. Follow-up:

There is still a difference with the open air, because the balcony does not stretch outward, and Miao Miao always grows in one direction. I asked my relatives who grow vegetables, and they told me that I had never encountered this situation after growing vegetables for decades... Then the only way to let it continue to grow is that the stem is too long, and it basically falls when it is watered. . . .

The seedlings grow in one direction, which is caused by phototropism, and it can be solved by turning the pot. You can still get up on your own after watering and lodging. If the nitrogen content of the soil is too high, the stem will grow.

Then let it grow. Hehe.

The reason for the growth of the seedlings and the way to rescue them.

The main reason for the phenomenon of dead vegetable seedlings after emergence is worthy of our **:

First, vegetable seeds have pathogens and have not been sterilized.

Second, there are soil-borne pathogens in the seedbed soil that have not been inhibited or killed.

The third is the disease induced by continuous low temperature, rain and high humidity. The lodging of eggplant and melon vegetable seedlings is generally caused by cataplexy, blight and wilt.

Precautions for vegetable seedlings.

Cataplexy disease mostly occurs before the seedlings 2 true leaves, the blight is mostly harmful to the seedlings of eggplant fruit vegetables, and the wilt disease mostly occurs in the seedling stage of melon vegetables, these three diseases are most likely to cause vegetables to die, because they occur quickly The situation is the same, therefore, we should focus on prevention, and can play a good role in prevention and control.

Vegetable seedlings often die in greenhouses or greenbeds and other protected areas, and even die in whole beds. There are many causes of death, but they boil down to two main categories, those caused by microbial pathogens and those caused by environmental factors. The most common type of seedling death caused by biological pathogen infection is called seedling crushing disease, which is caused by a fungus called Pythium melon fruit.

Since planting radish seedlings above the roots close to the soil surface of the place dried up and thinned and died, every time the vegetable planted is, when it first sprouted, it was very good, and after a few days, the stem dried up, the vegetable seedlings lodging, spinach, cabbage are, cabbage has been planted twice This phenomenon has appeared, dying day by day, day by day, people are dying

The reason for the growth of green vegetables may be that the sowing is too dense, so before sowing, sprinkle less seeds or sow more evenly, if it is too dense, increase the distance and ventilation between the seedlings, otherwise it is too crowded and nutritious, and the sunlight and so on are insufficient.

It is possible that the seedlings grow because they are blocked by other vegetable plants. So get to an open, ventilated, sunny place in time. In addition, after the emergence of seedlings, when there is no growth, excessive application of nitrogen fertilizer is easy to cause growth, so when the seedlings are small, less fertilizer.

Soil that is too wet or not exposed to enough light can cause this phenomenon to grow.

In the future, you can plant vegetables to maintain the humidity of the environment, and do not water too frequently. If you have any questions, please feel free to ask, hehe.

The seedlings are too dense, the seedlings should be soothing, potted vegetables are not like ground planting, the ground is planted with ground gas to raise roots, and the seedling roots are very deep. If there are too many seedlings, the roots of the seedlings will be intertwined, and they will not grow much (one will remain in the state of the seedlings until they die) or grow long. In fact, the seeds do not need to be sown, you are not the earth, when you need to raise seedlings first, and then transplant them in pots.

Vegetables like cabbage, a 15 cm diameter pot is planted with up to 4, lettuce is also one, like vegetables need sunlight to grow well, but it is best not to direct sunlight during the seedling period, and then it is to control the water, do not dry or water, do not think that you must water more if you grow fast.

In your case, it is considered a seedling, and it is good to transplant the seedlings separately, and keep at least 3 to 5 cm between the potted seedlings and the seedlings.

The main thing is that the density of the seedlings is too large, so that the light is insufficient, in order to shine in the sun, the seedlings will try to grow taller in order to get better sunlight, but then there will be only height, no roughness, so if the seedlings are transplanted, the survival rate is very low.

In addition, if it is not lit in a shady area or a balcony, be sure to ensure that it has plenty of sunlight.

The next time you sow the seeds, don't be too dense, and if they are too dense, you should intersect the seedlings (pull out one plant at a time when the seedlings are very small, so as to leave room for lateral growth). The seedlings gradually grow, and the seedlings need to be indefinite during the period.

Just don't fertilize...

Hehe, at first glance, it's a person in the city. Vegetables that are not fertilized are fragrant and delicious. The soil is too fertile, causing the plant to absorb too much and grow abnormally. Just like people, if you give a baby a variety of vitamins every day, the consequences are self-evident.

If the soil is black, you don't need to add any fertilizer to grow vegetables. If it's yellow, a little bit is enough.

The density of the seedlings is too large, the ventilation is not good, the temperature is high, the seedlings will grow (that is, the growth is high but particularly weak), don't use medicine if you eat it yourself, pay attention next time, don't sow too many seeds.

Foot of the bottom; The day temperature is high, the night temperature is low, and the appropriate amount of water is just these twelve words, and if you master it, you will grow quickly.

Lack of nutrients, thanks to farm manure, maintain proper soil moisture.

Hello. Based on my many years of experience, slow growth has a lot to do with temperature. Don't water too much, as it may spoil the roots. Don't rush to fertilize either. Otherwise, all your hard work will be in vain.

Hello. For your information: There are many reasons why growing vegetables grow slowly, such as:

Low temperature, lack of sunlight for leafy vegetables, obsolete plastic film in sheds, lack of water in the soil, malnutrition, soil compaction and salinization, underground pest infestation, use of uncooked and fermented organic fertilizers, and unsuitable planting time for vegetable varieties, etc.

It is recommended to take corresponding solutions according to the different varieties of vegetables! You can also consult your friends about a better solution.

Thank you for your question.

When transplanting vegetable seedlings, it is recommended that technical instructors conduct on-site technical guidance in the field, and carry out planting and transplanting in strict accordance with the transplanting requirements of relevant vegetable varieties. Neither shallow planting with uncovered roots, nor deep planting to form seedlings"Ebb tide", keep the neck of the seedling base slightly above the surface. Therefore, when planting vegetables, it is recommended that it is best not to use weak seedlings, and select seedlings with vigorous growth, lush branches and leaves, and developed root system.

Rural vegetables are planted with vegetables, usually transplanted vegetable seedlings and planted, generally speaking, the root will gradually resume growth, but the growth is fast or slow, there have been encountered seedlings for a long time, after treatment, and the growth has recovered gradually lush, said that the vegetables do not grow after planting, should be cultivated and weeded in time, and apply farmhouse organic fertilizer, for example, decomposed poultry manure, human manure, rapeseed meal, soybean meal, farmhouse manure and other humic acid, humus, improve soil organic matter content, make the soil soft and breathable, conducive to vegetable rooting.

Another situation is that vegetables do not take root, it rains continuously, the vegetables planted are too waterlogged, the vegetables do not take root, there are some vegetables, suitable for planting in spring, there are some vegetables suitable for planting in autumn, to put it simply, there are some vegetables that like low temperature, there are some vegetables that like high temperature, we plant cabbage radish in autumn and the seedlings stretch quickly, and the growth rate is balanced and stable. After the seedling age is more than 50 days, it forms a "small old seedling", and the growth potential is obviously weakened after transplanting, and there are small old seedlings and bitter gourds, serious flowering, melons, and no melons.

One is that the soil moisture is too much or the watering is not right, and it is generally necessary to water after transplanting, and some have to be watered for several days after transplanting. If the soil moisture is too much, it will lead to poor soil ventilation, and the roots will not be able to breathe and the problem of rooting will occur, and then it will naturally not be able to take root. This may lead to root burning or insufficient nutrient supply, which will eventually cause vegetables to grow too slowly.

In addition, if the soil contains a large number of pathogenic bacteria, diseases and insects, it will also cause the growth of vegetables to be too slow. Of course, there is also heavy cropping, which will also inhibit the growth of vegetables after planting.

Create a soil environment that is suitable for root growth.

In order to promote roots, the most important thing is to create suitable environmental conditions for root growth, including suitable temperature, water and fertilizer, oxygen, etc. Before the seedlings are planted, it is necessary to pay attention to the moisture and temperature, and immediately cover the plastic film after planting, and lay rice husks or crush straw in the operation row, which is conducive to maintaining a high ground temperature; The planting water must be as small as possible, it is best to only water around the planting hole, and the slow seedling water can be flushed with chitin and biological fertilizer to promote root disease prevention; It is necessary to pay attention to the method of mulching film, avoid covering the whole shed with the ground, and leave room for the "breathing" of the root system. When the environmental conditions are good, the root system can absorb more nutrients after regeneration, and promote the strength of the plant.

Fertilization should be carried out. Vegetable seedlings that don't grow well may be undernourished.

In the vegetable stubble period, the high temperature stuffy shed, at the same time decomposing manure, the size of the seedlings planted separately, control the prosperity and promote the weak, separate management, strengthen pruning, appropriate adjustment.
