Is it harmful to the body to eat the foam box vegetables?

There is no toxicity in foam box planting, but the foam material is exposed to the sun outside for a long time, plus some nutrients in the planting soil, and the chemical components added by planting and fertilizing vegetables, it is likely to volatilize poor harmful substances for a long time, and there is no toxicity or uncertain factors, so it is recommended not to use it for a long time.

Foam box vegetables are not toxic. Its main components are polystyrene and foaming agents, and these chemicals can be naturally weathered to become fine dust, but they cannot be broken down by microorganisms and converted into ionic nutrients, which cannot be absorbed by vegetable roots.

The substances contained in the foam box are also carcinogenic ingredients, and there is no scientific basis for the online claim that foam box vegetables can cause malignant tumors in humans.

Plant roots do not absorb foam box substances

Zhong Xinmin, a researcher at the Vegetable Research Institute of the Zhejiang Academy of Agricultural Sciences, believes that "foam box vegetables are toxic and non-toxic, mainly from the composition of the foam box and the absorption of vegetable roots." The composition of the foam box should be polyethylene, and its polymeric molecular structure is strong and large, even if it is naturally high and strong light on the balcony.

Its decomposition is extremely limited, and even if it is decomposed, what is decomposed should be large molecules. A long time ago, human beings believed that the absorption of nutrients by plants was humus, which is the humus theory in the history of science, and humus is of course a considerable material structure. In the middle of the nineteenth century, the German chemist Liebig proposed the theory of minerals.

Overturned the humus theory, that the absorption of nutrients by plants is minerals, minerals are of course quite small molecular structures, and mainly in an ionic state, since then, human understanding of plant nutrient absorption has embarked on the road of real science, and then, human beings have given birth to the fertilizer industry. ”

No.

The foam box is a kind of container that many people like to grow vegetables, because it is light and lightweight, and it is very convenient to move and punch holes, but many people have doubts and worry that it will be toxic and harmful to health when used to grow vegetables. In fact, the foam itself is a material that does not have any toxins, as long as it is not eaten directly and not heated, it will not be released to the outside, so we have no problem growing vegetables in it.

Precautions for growing vegetables in foam boxes.

If you use foam box soil to grow vegetables, you can't plant them directly, and you need to make holes in the foam box before you can use them, otherwise there will be water accumulation, which is very unfavorable to the growth of vegetables.

Don't move the foam box after punching, it is not a solid container itself, it is more fragile after punching, and it will be damaged if you don't pay attention to it, and you can grow vegetables after everything is processed.

The main component of the foam box is polystyrene, which has good stability and is not easy to decompose under normal light. And the foam box is very popular with people in the city, because they often have no place to grow vegetables, and the foam box perfectly meets their needs.

However, the foam box is replaced regularly at the end, and the soil applied to the foam box at the time of planting, as well as some fertilizers, some substances and chemical components in it may react with the plastic, foam and other substances in the foam box, releasing harmful substances, and it is not recommended to use it for a long time.

There is no toxicity in the foam box to grow vegetables, but the foam material is exposed to the sun for a long time, coupled with the chemical ingredients added by fertilization when planting vegetables, it is likely to volatilize bad harmful substances when used for a long time, and there is no toxicity or uncertain factors, so it is recommended not to use it for a long time.

The foam box is mainly composed of polyethylene substances, the material molecules are polymerized firmly, whether it is outdoors or indoors, its decomposition is very limited, and the root system in the process of absorption, is to absorb the organic molecules in the soil, and the foam box is partially decomposed of macromolecules, so it will not be absorbed by the root system.

No. Foam box vegetables are generally not poisonous, but for the sake of insurance, it is best not to eat them. Because the foam box will volatilize bad substances in the outdoor long-term sun exposure and air pollution, and at the same time, it will be affected by fertilizers, pesticides and other substances in the breeding process to produce a certain reaction and release harmful substances, so the vegetables grown in the foam box may be toxic, and it is recommended to eat less.

The composition of the white foam box is stable and non-toxic, and it basically does not affect vegetables.

On the question of whether foam box vegetables are toxic to the human body, the reporter interviewed Guo Shirong, a professor at the Department of Horticulture of Nanjing Agricultural University. Professor Guo told reporters that the composition of the white styrofoam box is generally polystyrene, which is relatively stable, difficult to decompose, insoluble in water, and has no toxicity.

When encountering high temperatures, toxic substances may be produced, but because there is soil in the box when planting vegetables, and the plant itself has a strong purification ability, it basically does not affect the vegetables.

Professor Hu Chuanjiang of the School of Materials, Chemistry and Chemical Engineering of Soochow University holds the same view. However, the professor suggested that it is best to use flower pots to grow vegetables, and if you choose foam boxes, it is best to choose foam boxes for packaging food or seafood, because most of these foam boxes are made of disposable foam, do not use foam boxes made of disposable lunch boxes or foam boards, and do not use foam packaging boxes for chemicals, because such packaging boxes may have chemical residues.

The vegetables grown in the foam box are not harmful to our body, the nature of the foam box is very stable, just putting a certain amount of soil inside it to grow vegetables will not let it decompose toxic substances. However, we should use good foam boxes with guaranteed quality, because some inferior foam boxes still have the risk of releasing harmful substances.

Now there are a lot of people living in the city have the habit of using the balcony space to grow vegetables, because there are fewer fields in the city, people will prepare several foam boxes to put on the balcony, and then spread the soil into the foam box to grow vegetables, so this kind of vegetables grown in the foam box will not be harmful to the human body?

Eating vegetables grown in foam boxes will not cause harm to our body, because the nature of foam boxes is very stable, and in the process of growing vegetables, it will not volatilize harmful substances to the human body, so we can eat vegetables grown in foam boxes with confidence.

However, it should be noted that we must give priority to the best foam box when we grow vegetables in this way, because some bad merchants sell inferior foam boxes that are easy to release some harmful objects, and it is very dangerous to use this foam box to grow vegetables.

Eating the vegetables in the foam box is not harmful to the body.

Bubble plastic box is a very widely used packaging products, many families are empty after shopping some bubble packaging boxes, these foam boxes are often large in size, idle at home to occupy space, if the balcony or rooftop at home has enough space, it is better to make full use of these foam boxes to grow vegetables.

Foam boxes have some advantages over ordinary plastic containers: they are easy to modify, resistant to sunlight, and not easy to age and weather. Foam box planting is the same as ordinary balcony planting, but according to the characteristics of foam box, it needs to be considered in detail and done thoroughly.

Here's how to grow vegetables in a foam box:

The first is to actually measure the size of the balcony or roof and foam box, or you can use the foam box to pre-place on the balcony, and plan and arrange the space location of each foam box. The early location planning must be done well, and the space position of the box cannot be moved around after being planted with soil, because the foam box itself is not very strong, especially after drilling and transformation, it is easy to break during the moving process.

Once you've planned your location, it's time to renovate your boxes. Most vegetables are not tolerant to waterlogging, so make sure you have holes in your boxes. Vegetables that are not water-tolerant are planted, and the box is not deep, and the water elimination hole is generally punched at the bottom of the box.

If the vegetables planted have a certain waterlogging resistance, or the box is relatively deep, you can punch the water elimination hole in the middle and lower side of the foam box, so that the scale can store a certain amount of water at the bottom of the box, so that the vegetables are not easy to cause drought and waterlogging. Generally, there are not many water elimination holes, three or two are fine.

Foam box vegetables are non-toxic. The main component of the foam box is polystyrene, which is an organic compound, with stable chemical properties, insoluble in water, high temperature resistance, and is not easy to decompose under ordinary light, so it generally does not release toxic substances. However, for safety reasons, it is best to choose a special box for vegetables, because this kind of foam box is placed outdoors for a long time, and it is difficult to ensure that it will not release harmful substances under the invasion of sun and rain, air pollution, etc.

Foam boxes are very common in life, not only can be used to package fragile goods, but also to refrigerate and keep warm, the most important thing is to grow vegetables, etc. But many people say that the vegetables grown in the foam box are poisonous, and the vegetables grown cannot be eaten, so are the vegetables in the foam box poisonous? What are the cultivation methods?

Is foam box vegetable poisonous.

Foam box vegetables are non-toxic. 。The main raw material inside the foam box is EPS, commonly known as polystyrene. When this product encounters high temperatures, it does produce toxic substances.

However, when planting vegetables, the box is isolated from the soil, and the plant itself has a strong purification ability, thereforeThere is basically no effect on vegetables。SoThe vegetables grown in the foam box are edible, there is nothing to worry about in particular.

Foam box planting method.

1. Choose a location

The foam box can easily break, especially if you touch it casually at a later stage. So before planting, be sure to determine whether the vegetables you are planting are sunny or shade-loving plants. If yesSunnyIt is better to place it next to the balcony, so that you can avoid moving later.

2. Punch holes at the bottom

The bottom of the foam box needs to be perforated。Because the foam box has a very poor water storage capacity, if it is inMake a hole in the bottom, the water will immediately flow out of the bottom. Therefore, it is best to dig a hole 5cm from the ground on the side of the foam box before breeding, so that the water can slowly penetrate into the soil.

3. Planting

First put some soil in the foam box, then plant the rapeseed to be planted, and finally cover it well, and water it a little. However, if you are planting water-loving plants such as watercress and water spinach, you only need to choose some clay soil, add water and stir it into a thin mud, and plant seeds.

4. Management

Moisture requirements:If you are planting water-loving plants, then water more, otherwise, as long as the soil is moist, at the same time, drainage measures should be done in the rainy season, and less watering in winter to avoid frost damage.

Light Requirements:If you are planting light-loving plants, then you should give enough light every day, and if you are a shade-loving plant, then you should do a good job of shading in summer to prevent the temperature in the box from being too high and affecting the growth of the plants.

Many people will choose to use foam boxes to grow vegetables, foam boxes contain polystyrene calling, heavy metals and other substances, so, foam box planting vegetables will be harmful? The details are as follows:

Is there any harm in growing vegetables in foam boxes?

There may be such a hazard in the foam box, that is, the foam box contains some harmful substances, and there may be some additives and envy agents in the foam, or the foam is originally filled with toxic substances such as heavy metals, which will cause certain harm to the body.

There are some reports on the Internet that foam boxes are toxic, and the main ingredient of foam boxes is polystyrene, which is an organic compound and is indeed harmful to the human body. However, the substance contained in the foam box has a relatively reliable structure and high stability, and generally does not release toxic substances.

Generally speaking, the foam box releases very little toxic substance, and the plant has the ability to purify, so it is basically safe to grow vegetables with the foam box.

Can you eat the vegetables grown in the foam box?

Even in the hot summer, it is difficult to decompose vegetables grown on the balcony in a foam box, so it is okay to grow vegetables in a foam box. Vegetables grown in foam need to absorb nutrients from the soil, and the quality of the soil will directly affect the growth of vegetables.

If you are worried about the decomposition of toxins in the foam box into the soil, and then absorbed by the vegetables, affecting the growth of vegetables, this is undoubtedly a lot of concern.
