近年来我国冬季多遇特别的低温天气,这给我们北方地区冬季温室作物生产带来了很大的挑战,数九寒天气温很低,温室和大棚内的蔬菜、草莓、花卉等遭受冻害造成损失以致绝产的事屡见不鲜。为了更好的预防温室和大棚作物遭受冻害,搞好冬季棚室作物生产,现介绍几种预防温室和大棚作物受冻害的方法。1、建温室前选择一个好地点,预备好材料,建设一个外有保温保护层、内有完整的防寒沟、砖包复合孔穴墙体、内撑外压、结构合理、透光率
In recent years, China experienced many special cold weather in winter, which posed a great challenge to crop production in the winter greenhouse in the north. In the cold weather of the past few days, the vegetables, strawberries and flowers in the greenhouse and greenhouse suffered losses due to frost damage As a result, the phenomenon of abortion is not uncommon. In order to better prevent frost damage to crops in greenhouses and sheds and improve winter shed crops, several methods to prevent crop frost damage in greenhouses and greenhouse crops are presented. 1, before building a greenhouse to choose a good location, ready materials, building an outer layer of insulation, there is a complete cold trench, brick composite hole wall, the internal support pressure, the structure is reasonable, the light transmittance

随着经济的发展,电力工程的建设节奏加快。但是,土地和规划的问题使电力工程的站址、路径成为难题。很多变电站和线路杆塔不得不在土壤电阻率很高的山顶建设,山体对接地工程的影响比较突出,而该领域的有关研究工作正待开展,现阶段传统的接地设计尚不能正确分析山体对山顶变电站接地各种影响,只能根据经验判断,导致接地材料浪费、甚至是接地电阻或跨步电压超标等一系列安全问题。为了能够对山体影响山顶变电站接地情况作一个客
