In recent years, the efficiency of vegetable cultivation has been high, and the enthusiasm for building sheds has been increasing. However, as the shed grows and becomes wider and wider, the cost of building a shed is also rising. A 150-meter shed will cost more than 200,000 yuan, which is more than the cost of building a house at home. Most of the winter-warming vegetable greenhouses built in the northern regions are soil walls. Although the insulation is good, the structural strength is low. Improper maintenance is prone to collapse and affects the service life of greenhouses. Recently, when interviewed by Yuhuang Town, Shanghe, Shandong Province, the author discovered that the back wall of some local sheds was improperly handled, and water leaked from the back slopes. As a result, the walls collapsed. The sheds have just been built for three to four years. The top of the wall is already as thin as a brick. There is no place to go, and it has even come into contact with the back slope. In this reminder farmers friends, the wall is the main part of the greenhouse, we must do a good job in maintenance. When setting the slope, choose a film with large thickness, good toughness, and long service life. As long as it is a perforated place, the lower part must be topped with plastic paper, straw, etc. to avoid dropping after stepping on, and the outside rainwater will accumulate and then penetrate the wall. Cause wall soil to collapse. Where water leakage has been found, it must be dealt with in a timely manner, top leakage parts, repair damage, and ensure no leakage of water to soak the wall. 360 Degree Ptz Camera,1080P Hd Camaras,Audio Wireless Wifi Camera,Hd Wifi Camera Shenzhen Zuomi Technology Co., Ltd. , https://www.zuomicamera.com
