rThe widespread use of multi-span greenhouses has set off a trend of popularity in the domestic market. Qingzhou Boyuan Greenhouse Horticulture Engineering Co., Ltd.
Aiming at the common problems in greenhouse application, we made a summary and found out the solutions.
, rFirst, the distance between the two sheds is too small. In order to save land and improve land utilization, many users leave a small distance between two greenhouses, some even less than two meters, which brings various problems to the production of greenhouses. First of all, the greenhouse in the front provides too much shade to the back, which is very detrimental to the growth of vegetables in the front half. Also, when it rains in winter, it will cause the snow to pile up in front of the shed. In addition, the rainy season in summer is not conducive to the drainage of accumulated water. According to relevant authoritative experts, the space between the two sheds should preferably be between ~ meters. This can not only avoid the occurrence of the above problems, but also ensure that the greenhouses will not shade each other, and can also play a windproof role.
, Second, the drainage system of multi-span greenhouses is not perfect. Summer is a rainy season, especially users in the south should take this issue into consideration. However, many users do not consider the issue of drainage during the design process, and do not take predetermined preventive measures. In this way, in rainy weather, the greenhouse will have drainage difficulties, and water will accumulate around the greenhouse and become inaccessible, causing various problems in the greenhouse. Our company’s suggestion: At the beginning of the construction of the greenhouse, a drainage ditch running east-west and as long as the greenhouse should be dug in front of the greenhouse. The width and depth of the drainage ditch should meet certain requirements to facilitate the timely flow of water on the greenhouse surface. , to prevent water accumulation.
, Third, there is a lack of protection measures for the back slope of the earthen wall of the multi-span greenhouse. Some users tend to ignore the protection of the back slope, and the erosion of summer rain will have many adverse effects on the production of the greenhouse, which greatly reduces the service life of the greenhouse. Some users also consider this problem, but take unfavorable measures, so the effect is not very good. Our company recommends that during the construction process of the greenhouse, you should first wrap a layer of plastic sheeting on the back slope, and then wrap a layer of non-woven fabric on the outside and fix it, so that its service life can be correspondingly extended, and the effect is still the same. pretty good.
