"The dangers of growing vegetables in foam boxes ?"
Many people dare not use the foam box to grow vegetables because of a doubt that the harmful ingredients in the foam box will penetrate into the soil, which will contaminate the vegetables and be eaten into our mouths to affect our health.
In fact, such doubts are absolutely unnecessary. Most of the foam boxes we usually see are polystyrene foam boxes, which is a very stable non-toxic material.
It will soften above 100 ℃, liquefaction may occur above 200 ℃, and substances harmful to the human body will only occur at a satisfactory high temperature.
Therefore, it is only necessary to avoid the source of the fire and use the foam box at normal temperature, which is very safe even in the year-round sun exposure.
Although pure polystyrene foam can reach food grade, there are also a small number of unsatisfactory foam boxes from unsatisfactory manufacturers.
Therefore, when choosing a foam box for cultivation, we should try to choose a relatively small odor. If it is a brand new foam box, it is best to leave it for a period of time to dissipate the odor.
Together, when we choose a foam box, it is best to choose one that was originally used to contain foodstuffs such as vegetables and fruits. Do not use chemical materials such as paint to avoid secondary pollution.
Some flower buddies will ask, will the foam that broke out after the foam box break down and fall into the soil, will it be absorbed by the plant? The foam box itself is also a kind of plastic. We all know that plastic is difficult to be broken down by microorganisms and transformed into ionic nutrients, which cannot be absorbed by plants.
This is also one of the reasons that plastic products are so harmful to the environment. Therefore, vegetables grown in foam boxes are not poisonous, and planting vegetables in foam boxes is an environmentally friendly action worthy of waste reuse.
"Benefits of Growing Vegetables in Foam Boxes"
The use of dill flowers in foam boxes is prevalent, of course, because it has many advantages.
The first is price advantage. The foam box is generally long, this shape is very suitable for making vegetable boxes. It can give vegetables a satisfactory width and depth for dense planting. If it is an equal-sized flower pot, it may take 50 to 60, and the recovered foam will be recovered. Boxes are only five or six yuan or even free.
Secondly, the thermal conductivity of the foam box is extremely low, and it has a strong thermal and thermal insulation effect.
In winter, you can reduce the heat loss of the soil, and increase the pot temperature to help the vegetables and fruits to overwinter. In summer, it can relieve the sudden rise in soil temperature caused by the sun.
