Nowadays, people attach great importance to green health, so they like to grow some vegetables themselves, and it is also common to plant vegetables on balconies. People choose to plant vegetables on the balcony with foam boxes because foam boxes are cheap, square, neat, easy to manage, and beautiful to plant. But some people on the Internet say that the vegetables planted in foam boxes are carcinogenic and cannot be eaten. Is this true? Qingdao RongfaManufacturer of foam boxTo parse:

The main chemical component of foam box is polystyrene, which has been used for more than 100 years. According to its chemical structure, it is basically non-toxic, can be used for food packaging, and has relatively stable chemical properties. But if this foam box is exposed to sunlight and high temperature for a long time, will it decompose any toxic substances?

Professionals use polystyrene foam for experiments. Under the condition of boiling for 3 hours, the weight reduction is very small, lower than the detection limit. Judging from the substances dissolved in water, polystyrene foam is also within the detection limit of the instrument, indicating that it is very stable under experimental conditions. When the external temperature is above 100 ℃, it will naturally soften, and when the temperature reaches 200 ℃, it will completely melt into a liquid.

The important thing for growing vegetables is the soil, not the container. The nutrients required for plant growth mainly come from the soil. In addition to water, mineral elements in soil can be absorbed by plants in the form of plasma, such as some benzene, which is a long-chain component that is basically not absorbed by crops.

The foam box is relatively light and cheap, and it is really a good container for home grown vegetables. Compared with the hollowed out flower pot at the bottom, the foam box is really airtight for growing vegetables, but as long as you dig some holes in the side and bottom of the box, water can seep out, which is definitely better than the flower pot.

Usage suggestions:

1. Although there is no necessary connection between "poisonous vegetables" and foam boxes, porcelain and wooden containers should also be good choices for growing vegetables.

2. Choose foam boxes produced by conventional manufacturers, and do not use wastes or foam boxes of unknown origin.

3. In fact, growing vegetables in foam boxes has many advantages, such as keeping warm in winter, being cheap and easy to buy.
