First, increase the permeability of
8x6 plastic garden sheds film: high transmittance Wu Dimo, timely cleaning dust on films, snow, etc., can enhance illumination enhance Pengwen;
Second, to improve straws Insulation: Insulation strong straw mat covered greenhouses. To better improve the insulation performance, in the depths of winter season to prevent snow and wet straw mat, may be covered with a layer of plastic sheeting or ordinary waste plastic film on a straw mat in previous years;
Third, the increase in greenhouse back wall insulation: The back wall may be a layer of brick in building walls posted, or build hollow wall insulation, walls filled with straw or polystyrene foam board, the effect is also very good, cold region directly Architecture a firewall, easy to raise the temperature;
Fourth, Pengwai cold ditch digging: in greenhouses outside deepened 40-60 cm wide and 40-50 cm of cold ditch, fill in sawdust, weeds, manure, straw and other insulation materials, mulch after tamped seal groove, to achieve the insulation effect. In approaching cold night in the
plastic backyad sheds around Enclosing straws or corn stalks, can improve Pengwen 2-3 degrees; also available in greenhouse fumes around, to prevent heat loss around the greenhouses;
V. shed dig ditches back: The studio in greenhouse planting grapes dig back furrow methods to improve to mild temperatures inside the greenhouse. That along planting rows of grapes from 30-35 cm crown, deepened 45 cm, 50 cm wide ditch, ditch covered with about 5 cm of rice husk or bran, from trench sidewalls 5 cm every 50 cm 1 stakes play is fixed between the side walls filled with piles of corn stalks. Ditch the top 60-70 cm long, 10 cm diameter bundles of corn stalks blanket, ditch earth, in addition to leaving a job Road, the rest of the ground covered with plastic film, forming a whole greenhouse inclusive communication "S" shaped groove, in terrain Office, located slightly higher opening, promptly opened or closed to control the ground temperature;
Six greenhouse cultivation within: high ridge cultivation, when planting can be in on the ridge covered, which can increase soil temperature 2-3 degrees. When
camping mobile house using flat plot cultivation can set up a small shed, to raise the temperature, which is what we call "shed in the shed";
Seven, set up temporary warming measures: timely relieve cold, frost and other weather disasters and adverse weather cloudy day without light, can temporarily set 2-3 power 1600-2500W the fan heater in the shed, in order to prevent the greenhouse humidity too big, causing leakage, should adopt bathroom heaters, fan heaters export orientation, not directly into the plant;
Eight, reflective screen hanging in the shed: shed light not only increased, but also improve the greenhouse temperature. The method is hanging on the wall in the shed coated with a metal layer of plastic film or foil, suspended one meter every 2-3 meters. Reflective screen suspension, reducing the absorption of the wall of the heat, it can raise the greenhouse temperature 2-3 degrees, while increasing the greenhouse lighting, promote fruit coloring shed;
Nine, an appropriate increase in the greenhouse of smoke: We will burn firewood lit bored out to smoke, increase the release of carbon dioxide concentration, enhanced atmospheric inverse radiation, from the insulation.
