Description

Three layers of dual protecting type green house of vegetables

Technical field

The utility model relates to a kind of green house of vegetables, belongs to field of agricultural production technologies.

Background technology

Winter warm type vegetables in day-light greenhouse booth is the new things that rise and development gets up in recent decades, and its rise and development allows the food configuration of national most areas that great changes have occurred gradually, also allows neighboring countries and regions obtain certain material benefit simultaneously.It not only allows numerous vegetable growers develop household economy rapidly, promotes again and driven the development of local economy simultaneously.Along with booth popularization throughout the country, the pattern of booth, standard are being updated, planting technology constantly promotes, pattern of farming also constantly changes, but because green house of vegetables developing history is extremely short, the standard of lack rigorous, science, suiting measures to local conditions, also there are some drawbacks at booth construction, booth vegetable in producing in the whole nation.For example: the television cameras that several years ago after northern area chance heavy snow, booth is collapsed by pressure come clearly into view, what the main cause that booth is collapsed by pressure is, answer is exactly that agent structure is unreasonable, also have a kind of phenomenon be exactly in kind in autumn winter freeze to death or not long, as wanted, allow it grow the class that dish just reduces kind of plant.For example: a variety of Chinese cabbage, little rape or spinach and so on, why the booth of building does not reach plantation ideal, and except the low odjective cause of local climate temperature, its main cause is that the pattern, construction standard, the heat-retaining condition that are subject to built booth limit.Problem such as above-mentioned existence, as the bottleneck production that lock ring northern booth vegetable always, northeast, the northern area to the north of 38 ° of north latitude particularly, western part to the north of in the of 30 °, the Northwest, the restriction that low temperature is produced booth vegetable particularly highlights, and this is that northern area much does the knotty problem that the agricultural science and technology personage of booth vegetable faces.With regard to the overview of green house of vegetables, no matter be middle part or northern territory, the general amplitude of temperature in daytime canopy differs very not large, and key is night, especially after midnight, just differ greatly in the North and South, this is because canopy internal and external temperature contrast in the North and South differs too large, particularly cold district to night canopy internal and external temperature differ too large, cause the cooling of canopy face to accelerate, temperature of shed is sharply declined, because canopy internal-external temperature difference is larger, cooling rate is just faster.Kind slum-dweller, in order to keep temperature of shed, is adopted various measures, some thickened heat insulation layers, and the use stove fire temperature raisings in canopy that also have etc., though these ways can improve certain effect, can not fundamentally resolve contradiction.
