What do you know about the risks of growing vegetables in greenhouses?

With the popularity of greenhouse cultivation, many people say that greenhouse cultivation is unprofitable, but I think, why can others make money by cultivating the same greenhouse? It's easy to understand that planting is risky, but if you research the market ahead of time and don't follow suit, you can make money. Growing vegetables in a greenhouse, in fact, many times, once you don't pay attention to the word, there is a harm of fat.

Therefore, <> what kind of fertilizer hazards can cause greenhouse construction is a relatively high project cost. We used to build vegetable greenhouses out of bamboo and wood. The cost is relatively low and the service life is relatively short, only 2-3 years.

At present, most of the planting greenhouses adopt galvanized pipe structure, and the relative service life of bamboo and wood is greatly extended, up to 8-10 years, and the cost is greater than the initial investment of bamboo and wood, but the annual cost is basically the same. Planting greenhouse vegetables should be planned, depending on how much you budget in advance, how much you lose the greenhouse, and then choose the construction of the greenhouse.

Disasters and diseases in the planting process are important contents of later prevention and control. Greenhouse vegetable varieties should be relatively resistant to avoid reduced yields or even no grain harvest due to the source of the disease. On the other hand, risk assessment of natural disasters should be carried out according to the actual situation of the greenhouse to reduce the risk as much as possible.

Vegetable greenhouse farmers for many years told me that if you want to grow a good greenhouse, it will take at least three years to explore, and no experience in a greenhouse should be an old saying "if you want to be poor, plant a greenhouse". It's bad to have a lot of experience. To plant vegetables, we must first inspect the market, select varieties, and carry out scientific management in the later stage in order to do a good job in the planting of greenhouse vegetables.

Do a detailed interpretation of the problem, I hope it will help you, if you have any questions, you can leave me a message in the comment area, you can comment with me more, if there is something wrong, you can also interact with me more, if you like the author, you can also follow me, your like is the biggest help to me, thank you.

First of all, it is likely to cause some natural disasters, so it is likely to lose money, or because of the wrong way of planting, or because of the temperature and environment is not suitable, so it is likely to lose money, and the risk is relatively large.

It is understood that the market will change, and there will be risks or fires due to weather conditions, and there will also be reduced production due to insect infestations, and poor management will also lead to risks, which will eventually lead to reduced production.

Now the vegetable market is not good, and because of the weather, many vegetables have died, the entire output has declined, and many farmers have suffered losses.

The risk of growing vegetables in greenhouses is actually quite large, and there are many types of risks. Below, let's briefly talk about some of the risks of growing vegetables in greenhouses.

First of all, the changes in various vegetables may be relatively large, and planting greenhouse vegetables may make a lot of money or lose all their money. In fact, on the surface, many growers who grow greenhouse vegetables are usually very busy, and all kinds of vegetables are also shipped out one by one, but we don't know when they are delivered. However, when we usually go to buy vegetables, we may feel that some vegetables are low for a while, and after a while, they will be doubled, which is the terrible thing about vegetables.

If you plant vegetables in greenhouses and catch up with other growers who have planted a certain kind of vegetables, it will definitely plummet and even be worthless. And if a certain vegetable grower grows less, then the ** soars very much, and the risk is great.

Secondly, bad weather will also cause a devastating blow to the vegetables in the greenhouse, increasing the risk of planting vegetables in the greenhouse. Although vegetables will not worry about the sun and rain in the plastic greenhouse, if there is a large typhoon, whether the plastic film can withstand the typhoon is a big problem. If a strong typhoon blows down the greenhouse, the vegetables in the greenhouse will suffer, and the yield reduction may still be the lowest loss, and the most serious case may really lead to no harvest.

Moreover, such a difficult natural disaster like hail will also cause a devastating blow to the greenhouse, after all, the hail that can smash the car sheet metal into a big hole is certainly not something that plastic film can resist.

Finally, the inside of the plastic greenhouse is relatively closed, and once pests and diseases occur, they will spread quickly, causing heavy losses to growers. Generally speaking, vegetables grown in a closed greenhouse will not be in contact with the outside world, and the probability of pests and diseases is relatively small. However, the resistance of vegetables in the greenhouse is not strong, and once there are pests and diseases, they will spread rapidly, and the slightest carelessness will cause heavy losses.

The stakes are high. Pests and diseases may be encountered, affecting the quality of vegetables, and also affecting the yield of vegetables, which may not be sold, may be unsalable, and will cause a lot of waste.

The risk is very large, and the risk that it is easy to occur is that these crops may not be able to grow, and there will be some diseases, and finally it will reduce the meaning of income and face some natural disasters.

The stakes are significant. It is easy to be damaged by the weather, it is easy to encounter insect infestations, and it is easy for vegetables to rot due to high weather temperatures.

The stakes are not particularly great. The risk is that the yield is relatively small, the light is not received, the ventilation is not particularly good, and some insect pests may be encountered during the planting process.

If you apply medicine, this problem will not occur. In recent years, Xiaoyang's melons have been planted very well, not only can be planted well, but also can be sold well, the most important point is to really master the planting technology, learn how to adjust the sowing date, and go to market early. When the cucumber grows, it can no longer be pesticides, in order to prevent insects and diseases, I often add a little vinegar to the water, and then spray it on the cucumber tree, the cucumber will not be sick with insects, and it will not hurt the human body, and the cucumber will be heavy green pollution-free organic vegetables.

Now the basic natural disaster meteorological department can **, and the accuracy is also very high. General natural disasters can be very effective to minimize, greenhouse vegetable planting is more resistant to disasters than normal land planting, easier human control, so that the loss is minimized. First, natural disasters, such as wind, snow, rain, low temperature and cold wave and other natural factors, which are also the biggest risk of greenhouse planting, so we must do a good job of prevention in advance to strengthen the wind and snow resistance of greenhouses.

As long as the farmers plant, they should manage diligently, operate carefully, and master the room temperature control of the greenhouse. The vegetables in the greenhouse are rushed to the market, and the income of one acre of greenhouse is three times the income of growing grain. Therefore, greenhouse planting vegetables is profitable, farmers can standardize to promote, greenhouse through the greenhouse effect, change the microclimate of the local space to achieve off-season planting of crops, can be early or postponed to the market, staggered sales peak, obtain higher **, achieve high output value and high profits, but also effectively reduce the impact of climate, pests and diseases, and improve yield.

You have to go back to put the quilt on the next knife! Otherwise, the plants will freeze to death! Others go home to avoid the rain when it's raining, windy, thundering, and flashing!

You have to run into the greenhouse! If you can't bear it psychologically, let's do something else! The vegetables of the past few years are really not good!

Organic fertilizer must be cooked, you can dig a pit in the ground, and then wrap it with thick plastic paper to prevent the loss of fertilizer liquid. It can also ensure that the bacteria and eggs are killed by high temperatures.

The market has been constantly changing, and the greenhouse film may be damaged due to weather conditions, and there is also a risk of fire, and at the same time, it will also reduce the yield of vegetables due to improper management, affecting vegetables.

First of all, the awareness of the market is different, and now people's living standards are particularly high, so the requirements for materials are also constantly improving, so there are great requirements for the variety and quality of these vegetables, and the planting of vegetable greenhouses also needs to invest a certain amount of money and cost, and some pests and diseases will also occur.

If you grow vegetables in greenhouses, you need to pay attention to the soil problem, after all, good soil can make vegetables grow better, and at the same time, it can also reduce many other diseases.

1. **: If the early judgment is wrong, when the growth is over, the ** continues to be low, and there may be a risk of loss.

2. Disease: If there is an outbreak of a large-scale disease in that year, it is difficult to remove it, so the harvest will be affected.

Growing vegetables in greenhouses is risky and knows a lot. Traditional crops are based on the time of day, but using the greenhouse effect to grow vegetables is out-of-season. Among them, greenhouses may be planted out of season, and the problem of following the planting trend is more serious.

When they hear that there is a good market for a certain vegetable, many people will follow the trend and grow it en masse. Very large production volumes mean that they pay attention to multi-faceted risk management and comparisons, and the degree of risk is determined by multiple aspects. The risk of growing greenhouse effect vegetables should be moderate.

The main risk points are the initial investment and follow-up management, such as light, ventilation, humidity, temperature, etc., there is a certain normal market line of vegetables, Madura planting technology and market is stable, because it is only the risk of planting vegetables with greenhouse effect is not large, the main risk point is disasters and diseases, only in this way can we start from the source. Those who grow vegetables in a depressed greenhouse should think carefully. No matter what you do, there are opportunities and risks, and there are no absolute safety and risks; Growing vegetables with a greenhouse effect is a low-risk project in terms of climate-induced greenhouse effects.

Specific risks may include the risk of low market vegetables, the risk of damage from climate-induced greening, the risk of fires due to the greenhouse effect, wind and sunlight with reduced plant yields due to pests and diseases, which are sufficient to promote plant growth, and shelters can reduce wind damage. Convenient transportation can save shipping costs. Export Risk.

Greenhouse vegetable production is a complex manual labor that is time- and physically demanding. If certain pests and diseases can be avoided when choosing materials, the cost and plant risks of natural causes need to be considered.

Finally, it is clear that agricultural insurance should be taken out for the plants grown to reduce losses caused by disasters. In this greenhouse vegetable plantation, farmers earn at least 3,000 yuan per mu of land, and many farmers need to prepare greenhouse facilities to grow vegetables with greenhouse effect. Add mudas, then mass transplantation.

In the follow-up maintenance phase, pay attention to temperature changes, regular watering and nutrition, and pay attention to personnel evacuation. So people will win when growing vegetables, they naturally don't know so much technical knowledge.

Fresh vegetables are an essential product in everyone's life in winter, and now our living standards have improved. Winter vegetables are not limited to baskets, Chinese cabbage, and potatoes, but there is also a great demand for some fresh green leafy vegetables that are out of season. It shows that the cultivation of out-of-season vegetables in greenhouses and the demand of the market are very large.

In terms of everyone's purchase method, it is a basic common sense to first look at the quality and price of vegetables to consider which vegetables to buy.

For your friends, the most basic thing is to grasp the quality of the goods, and then look at the market sales in the sales market. Planting greenhouse vegetables is a low-risk new project, and the actual risks are about the risk of vegetable market trends, the risk of greenhouse destruction due to climate reasons, the risk of greenhouse greenhouses, the risk of vegetable disease and production limitation, and the risk of vegetable production restriction due to improper supervision. Most of this risk can be avoided according to reasonable manpower management methods, and whether it will be lost when planting greenhouse vegetables.

I think the key still depends on the people who run the greenhouse. In all greenhouses, vegetable planting in greenhouses includes the scale of greenhouse engineering, greenhouse characteristics, planting types, and the adjustment of vegetable market time. These are the basic factors that will determine whether vegetable cultivation is losing money or making money.

Depending on the situation of some disasters, the price of vegetables is also particularly harmful, and the reduction of snowfall in the planting area will lead to the stunted growth and development of vegetables.

There are also cases where the road surface is closed due to ice accumulation, and the transportation of vegetables causes great damage. Long-term delivery will lead to rotting or drying of vegetables, in other words, resulting in vegetables not fresh, in the sales market ** will be lower, and the profit will be low. Today's greenhouse planting labor intensity is much smaller than before, and China also has many agricultural machinery for greenhouse planting, which has greatly reduced labor intensity.

There are still certain risks associated with growing vegetables in greenhouses. If the planting technology is mature and the market is stable, then the risk is not very large. The main risks are marketing, soil problems, and so on.

The risk is not particularly large, and the survival rate is relatively high when planted in greenhouses. There may be temperatures that are too high, which may cause crops to suffocate and also cause their own earnings to be affected, leading to some diseases.
