Can't you go to someone's house 40 days before confinement?

You can go to other people's homes less than 40 days after confinement. Generally, it is equivalent to confinement after 30 days, and this kind of walking is also possible. Most confinement is to prevent yourself from catching cold, which doesn't mean you can't go to other people's homes.

The following is a digression for reference only.

Things in plastic greenhouses can grow healthily, thanks to the proper temperature inside, but sometimes the temperature inside is abnormal, such as when the climate outside is too low or it rains on cloudy days, which has a great influence on the growth of plants in greenhouses.

What should I do if the temperature in plastic greenhouse is low?

Leveled ridges become high ridges: When we walk into farmers' vegetable sheds, we will find that some farmers make the vegetable ridges very wide and high, instead of planting them on flat land, so as to absorb more light. Generally, the ridge is18cm high and 28cm wide, which can fully absorb light and raise the temperature in the shed.

Plastic film mulching in the shed: Plastic film mulching in the open air is a way to improve the low temperature. In fact, when the temperature in the shed is low, plastic film can also be used to cover it, which can protect the ground temperature more fully, improve the ground temperature and keep moisture.

Film sticking on the shed wall: There is a phenomenon in the shed that the temperature is very high when the light is strong during the day, but at night, without the sun, the temperature will become very low. In order to balance the temperature, the shed owner chooses to cover the shed wall with a reflective film, which can balance the temperature in the shed and release heat slowly.

Building a shed in a shed: When it is found that a single-layer shed can't meet the temperature demand of plants, smart farmers will use a shed to raise the temperature, and then build a smaller shed in the shed and cover it with plastic film, which can improve the sealing and raise the temperature.

Light bulb heating: install a light bulb in the shed. When the temperature is low, turn on the light bulb and use the heat emitted by the light bulb to keep warm. You can turn on the light bulb at night, or on cloudy days in rainy and snowy days to supplement the lack of temperature in the shed.

Whether you are confined to the moon or not, you must keep warm when you go out and don't let yourself catch cold.
