How can the heating of Dapeng reach more than 20 degrees in winter

Greenhouse crops have higher requirements for their survival microclimate environment, especially temperature, do a good job of greenhouse anti-freezing and warmth as soon as possible, seek advantages and avoid disadvantages, and strive to reduce the negative impact of winter rain and snow cooling on greenhouse vegetable production, it is recommended to focus on the following points:

Clean ditches to prevent damage. Dig a ditch system around the greenhouse, so that after the winter rain and snow, the water in the ditch and the channel outside the field can be removed in time, reduce the groundwater level in the field, and prevent the rain and snow water from backing up into the greenhouse, affecting the growth of vegetables in the shed.

Cover, do a good job of keeping warm and frost proof. Check the plastic film covered on the greenhouse scaffolding, and repair or replace it in time if it is damaged. Pay attention to listen to the weather forecast of the local meteorological station, and when the weather is fine, pay attention to ventilation and adjust the temperature and humidity in the shed; When the cold air comes, the shed door should not be opened too early, to increase the covering, the use of multi-layer covering, in the shed to build a plastic shed or shed, and cover the grass curtain, non-woven fabric, sunshade net, etc., to improve the temperature of the greenhouse, conditional night around the greenhouse around the grass curtain, can increase the temperature in the greenhouse 1 3, can effectively promote the growth of vegetables, enhance frost resistance.

Enhance light management. In winter, when encountering long-term rainy weather, it is easy to lead to the lack of light of plants, and the growth becomes weaker, and the grass curtains, non-woven fabrics, shade nets and other covers should be removed in time during the day to increase the scattered light exposure in the shed, and at the same time grasp the rainfall gap, and ventilate for a while around noon, and discharge harmful gases such as ammonia out of the shed in time. The old film should be cleaned for secondary use to facilitate crop lighting.

Catch up with the snow in time to reduce frost damage. Before the heavy snowfall, it is necessary to strengthen the greenhouse support, tie the plastic film tightly, and prepare for disasters such as strong winds and heavy snow. When the snow comes, it is necessary to clear the snow and shovel the snow in time to prevent the greenhouse from collapsing, and the snow on both sides of the vegetable greenhouse should also be removed in time to prevent the absorption of a large amount of heat and reduce the temperature in the shed when melting.

Do a good job in disease prevention and control. In winter, it is often accompanied by continuous rain, snow and low temperature weather, and the humidity in the shed is large, and the plant resistance is weak, which is easy to cause aggravation of diseases. We should pay special attention to the occurrence and spread of nightshade blight and gray mold for overwintering vegetables in greenhouses.

The first is to remove diseased plants, branches, leaves, flowers and fruits in the shed in a timely manner; The second is to strictly control the water use in the greenhouse, reduce the air humidity in the greenhouse, reduce the cause of disease of vegetables in the greenhouse, and fumigate with chlorothalonil smoke agent or Sukelin smoke agent on rainy (snowy) days; the third is to seize the good weather and actively choose the corresponding pesticide control; Fourth, combined with disease prevention and control, timely topdressing outside the roots, spraying potassium dihydrogen phosphate, Aiduo harvest, etc., to improve plant resistance.

Manage after the weather is clear. If the cover is suddenly clear after a continuous rainy day, the cover should not be removed immediately, otherwise the vegetables will wilt due to strong light exposure. Mulches such as straw curtains, non-woven fabrics or shade nets should be gradually uncovered and removed after a period of adaptation.

You can cover a straw mat outside the greenhouse, take down the straw mat when it comes out during the day, let the greenhouse bask in the sun, and cover it at night. Then burn a fire in the greenhouse to prevent the charcoal stove or light the heat lamp.

Hello, generally around 20 degrees Celsius. What kind of heating is used in your greenhouse? Thank you.

China's winter indoor sanitation temperature requirements include the following parts.

Room temperature The suitable range of temperature at the temperature of the centralized heating room is 16 20, and the suitable range of the temperature at the temperature of the decentralized heating room is 13 17, and the indoor temperature in winter in any area shall not be lower than 13.

Vertical temperature difference refers to the difference between the air temperature above the ground and the air temperature above the ground in the living room. If the vertical temperature difference is too large, the temperature of the feet will drop, and the body temperature regulation will be tense, which is not conducive to health, and the vertical temperature difference should be less than 3.

Horizontal temperature difference refers to the difference in air temperature at each point in the room at a distance. Generally, the temperature is low at the door, window, corridor, etc., and the horizontal temperature difference in the room is too large, which is easy to make people cold, and the horizontal temperature difference should not exceed 2 3.

In 2002, the state formulated the "Indoor Air Quality Standard", namely GB T18883-2002. The winter heating standard is 16 24, and the indoor temperature that meets this standard is the comfortable indoor temperature.

The energy-saving design standard for residential buildings in hot summer and cold winter areas stipulates that "the design temperature of bedrooms and living rooms in the heating indoor heating environment in winter shall be 16 18".

The indoor environmental quality standard item in the "2002 Planning and Design Guidelines for Well-off Urban and Rural Housing Science and Technology Industry Demonstration Communities" formulated by the state stipulates that the indoor temperature of the heating area in winter is 16 21. The World Health Organization's "Healthy House" standard stipulates room temperature, and the indoor temperature is maintained at 16 28 throughout the year.

The Energy Conservation Design Standard for Public Buildings GB 50189-2005 stipulates different indoor temperature standards for different building types such as office, sports, commercial, and catering.

Methods for measuring air temperature in public places" GB T18204In 13-2000, the method of determining room temperature was also specified. The indoor area is less than 16 test rooms** a little; More than 16 but less than 30 measure two points (the room is divided diagonally into thirds, and the second division point is used as the measurement point); More than 30 but less than 60 measurement points (the room is divided into four equal quarters, and its three equal points are used as measurement points); 60 or more measure five points (two diagonals of plum blossoms).

The height of the measuring point from the ground should not be less than that of the wall and the heat source.

National standards are the standards formulated by the technical requirements that are of great significance to the national economic and technological development and need to be unified across the country. The national standards shall be applied nationwide, and the standards at other levels shall not contradict them. China's standards have the nature of regulations, and China's mandatory standards are equivalent to some of China's mandatory regulations.

1.Gas heating.

Nowadays, the use of natural gas for heating has become more common, and biogas can be used as gas heating in rural areas. Straw gas stove is equivalent to turning waste into treasure and is an economical way to heat up. The use of vegetable fuel through the gas furnace, under closed anoxic conditions, the use of dry distillation pyrolysis and thermochemical oxidation to produce a flammable gas, mainly containing carbon monoxide, hydrogen monoxide, methane, ethane, propane, etc., also known as biomass gas, straw gasifier, is farmers do not spend money"Liquefied gas"

2.Burn electricity for heating.

Small sun and warm hair dryer can be regarded as the most common and approachable type of heating equipment using electric energy on the market, which is deeply loved by ordinary rural Giti users. This kind of heating equipment can be bought in large and small supermarkets, ** at about 100 yuan, very close to the people, and it is very convenient to use or store, it can be heated soon after connecting the power supply, and it takes up less space.

3.Clean coal + supporting stove for heating.

Compared with other clean energy heating methods, the cost of clean coal heating is relatively low, the guarantee is relatively stable, clean coal is flammable, high calorific value, long sealing time, burn-resistant and coal-saving, low consumption, no need to add coal frequently, time-saving and labor-saving, better use, greatly reducing the amount of coal used, more economical and energy-saving. Clean coal burning is low sulfur, low ash, low volatile, and more fully combusted, which can effectively reduce the emission of pollutants such as carbon monoxide, sulfur dioxide and nitrogen oxides. After combustion, less smoke and dust is generated, which can effectively reduce the pollution to the atmosphere, thereby improving the living environment.

Coal combustion is basically low-altitude direct discharge, and the combustion products are easily inhaled by the human body. The sulfur content of clean coal is lower, there is no black smoke and no peculiar smell when fully combusted, and the harmful substances produced are less, and the harm to the human body is very low, which can effectively reduce the phenomenon of gas poisoning in winter.

The indoor temperature standard of central heating in winter in China is based on this physiological demand of the human body. GB50019 2003 "Design Code for Heating, Ventilation and Air Conditioning" stipulates that the standard indoor temperature for central heating is 18 2.

In 2014, the seventh meeting of the 12th Standing Committee deliberated and adopted new regulations, requiring heating enterprises to ensure that the temperature of the user's bedroom and living room during the heating period is not lower than 18.

At present, this temperature standard is mostly used in China's central heating areas to ensure that users get a warm and comfortable indoor environment. Usually between 18 and 24 and 50% to 60% humidity is appropriate, when the human body feels most comfortable.

The indoor environmental quality standard item in the "2002 Planning and Design Guidelines for Well-off Urban and Rural Housing Science and Technology Industry Demonstration Communities" formulated by the state stipulates that the indoor temperature of the heating area in winter is 16 21. The World Health Organization's "Healthy House" standard stipulates room temperature, and the indoor temperature is maintained at 16 28 throughout the year.

According to the requirements, the indoor temperature should not be lower than 16. When the temperature is lower than this, district heating is required.

The thinner the heat dissipation, the faster the heat dissipation, the two groups are already a lot, only the burning time will be high for a long time, increase the burning time to adjust the room temperature.

It's not suitable, it's not as good as a firebox, if you use air conditioning, the air in the room is not flowing, which makes people very uncomfortable. Especially the elderly and children.

The power is also much larger than that of the fire box, and the compressor is powered on and auxiliary heating, which consumes more electricity than refrigeration in hot weather.

Not suitable, the lowest outdoor temperature is only a few degrees below zero, and the indoor temperature is completely acceptable. Air conditioning blowing too much is not good for a person's immune system. Especially in winter, it is easy to catch a cold as soon as you come out of the room. And it is easy to suffer from temperature sensory imbalance.

In terms of heating efficiency, the air conditioner is also very inappropriate and wastes too much electricity. Nowadays, there are many coal heating equipment, which are much more cost-effective than air conditioners. The main thing is to pay attention to the safety of use, but now coal heating equipment is relatively safe.
