Zhang Qinglin, a vegetable farmer in Quanfeng Village, Longguangqiao Town, Heshan District, Yiyang City, built a bamboo and wood structure shed of 480 square meters in 1998 and is still in use. The cement skeleton shed built by Li at the same time in the village has already been unloaded into a swing. The general service life of bamboo and wood structure sheds is two or three years. The reason why it has been used for five to six years is still to be used. Zhang Qinglin confesses the secret: the shed is well maintained and has a long service life. Then, how do the greenhouses do a good job of maintenance? Install it firmly when building. 1, shed feet into the soil to be in place. The depth of the soil in the shed must reach 40 cm in order to prevent the soil on the edge of the shed feet from declining year by year due to cultivation, which will cause the sheds to fall into the soil and cause the greenhouse to lean. 2. The connecting rod should be tightly fastened. In the greenhouse, the three connecting rods and the skeleton contact parts are fastened with iron wire. If bamboo rods are used to make connecting rods, the bamboo rods will dry and shrink and loosen. They should be checked frequently, and they should be tightly fastened and replaced at intervals of 2 to 3 years. The bamboo grass is aging and the greenhouse tilts. 3, greenhouse support should be strong. The concrete support rods at both ends of the cement canopy are two long and two short, that is, two short struts are aligned with the connecting rods, and the bottom is 1 to 1.5 meters from the bottom of the first sub-framework; the widths of the two long struts can be connected to the shed door Combine. In order to make the shed more secure, scissors can be used to form the support rods on the inner sides of the two sides of the greenhouse. For a shed 50 meters or more, a pair of scissors should be added on both sides of the shed. A long greenhouse shares 6 pairs of scissors. Conserve the scaffolding seriously. 1, timely support the skeleton. If the land is uneven, the thickness of the soil is not uniform, and the greenhouse may be tilted toward one end. Once it is discovered, it should be timely and righting. The method is: using 3 ropes or iron wire, pull the skeleton from the opposite direction, or use the bamboo pole to support in the opposite direction, and then correct each other. Before righting, loosen the soil at the bottom of the frame in the opposite direction to prevent the frame from being broken by excessive force. In some lightweight scaffolding, every 3 to 5 frames are tied with a bamboo to prevent deformation. 2, to prevent artificial increase in load. Do not arbitrarily pull lentils, sponge gourd, pumpkins and other climbing fruits and vegetables into the shed, and the rain and rain will increase the load on the skeleton and cause cracks, breaks, and collapse of the skeleton. 3, promptly consolidate shed feet. Because the soil itself in the natural world, ups and downs, and rain showers, etc., after a period of time, the hole will naturally form a hollow gap, in case of continuous drought after heavy rain, can easily cause greenhouse tilt, damage, so each year At least two feet should be returned to the feet of the shed. Frequent maintenance. 1, film maintenance. During the use of the greenhouse, do not use sharp objects on the film to avoid scratching the film. In the event of a crack in the film, it can be repaired with adhesive or repaired with Scotch tape. Polyethylene film can be repaired with polyurethane adhesive. The shed film is often kept clean. Generally 2 to 3 years after the shed film is used, it must be replaced so as not to affect the light transmittance and make the cultivation efficiency of the greenhouse unsatisfactory. Winter seedlings in greenhouses advocate the use of new membranes. 2, scaffolding maintenance. Steel sheds should be painted once a year with antirust paint, especially rusty parts and rust-prone connection parts. The wires and bamboo pieces embedded in the scaffolds of the cement canopy should be polished and packaged so as to avoid scratching the shed film. The individual frames with individual quality defects should be replaced in time to avoid affecting the overall firmness. Bamboo sheds and cement sheds should also pay attention to the firmness of the wire and bolts at the joints of the pillars and columns, as well as rust prevention. 3, ground anchor line, pressure film with maintenance. Ground anchor lines and lamination tapes, if loose or broken, should be fastened and replaced in time.
