温室大棚的建造技巧
温室又称暖房,如玻璃温室、塑料温室等,温室结构应密封保温,但又应便于通风降温,现代化温室中具有控制温湿度、光照等条件的设备,用电脑自动控制创造植物所需的最佳环境条件,下面黔农网小编就为大家介绍一下温室大棚的建造技巧吧!
Also known as greenhouse greenhouse, greenhouse and plastic greenhouse, greenhouse structure should be sealed insulation, but also should facilitate ventilation and cooling, with temperature and humidity control, the illumination condition in modern greenhouse equipment, computer automatic control required to create the best conditions for the plant, Guizhou Rural Xiaobian to introduce the greenhouse construction techniques!
1、平整土地和放线:按照设计好的日光温室平面图,陟盘测定好方位角,确定温室大棚的四个角,温室的四个角处打瞒桩,而后确定山墙和后墙的位置。
1, land leveling and line: according to the greenhouse plan design, the determination of the azimuth disc, determine the greenhouse four corners, four corners of a greenhouse from the pile, and then determine the wall gable and position.
2、筑墙:筑土墙所用的土,可以采用温室后墙外侧的土,也可以用温室前部栽培面耕层以下的土壤。如用温室前幽土,可将耕层(厚约25厘米)挖出,放在一边,向底层的生土浇水,一天以后,挖生土做土墙。先按土墙的厚度打夹板,填入刚挖出的湿土,用土夯或电夯夯实,每层约20厘米,夯实一层以后,再作第二层,直至达到要求高度。山墙于后墙要一起做,不可分段,只有这样才坚固。如果土壤的粘度不够,可毗中掺人麦秸。有些地区的土壤粘度很低,不能用夯实的方法建墙,这时可先在土中搀入一定量的麦秸和泥,做成土坯,待土坯干后,睡土坯墙。砌墙时,土坯之间要用草泥堵严,墙的内外也都要抹草泥。砖墙施工时要先将地基夯实,然后才可以砌墙,施工时要灰浆饱满,勾好砖缝,抹好灰面,墙的内外都要抹灰,以免漏风。砖墙层与层之间的空心不可过大或过小。一般空心的宽度掌握在5-8厘米之间。空心不可一留到底,要每隔3-4米,用砖将各层连接起来,以提高墙的牢固程度。空心墙可加用炉渣、珍珠岩、麦秸作填料,也可什么也不加,只用空气隔热,不加填料的空心墙,一定要做到没有裂缝。在砖睁封顶时,最好用泥糠封顶30厘米,使后墙与后屋面衔接紧密,提高保温性能。
2, the earthen walls: soil, soil can be used outside the wall of greenhouse, greenhouse cultivation can also use the front surface layer of the soil. As with you before the greenhouse soil, the topsoil (25 cm thick) dug up on the side of the bottom of the water to the earth, a day later, dig soil wall. First, we should use the thickness of the earth wall to splint, fill in the newly excavated wet soil, tamping with the earth tamping or electric tamping, each layer is about 20 centimeters, and then consolidate it for second layers until the required height is reached. The wall in the back wall should be done together, not to be segmented, only in this way it is strong. If the viscosity of the soil is not enough, it can be adjoined with wheat straw. In some areas, the soil viscosity is very low, so it can't build walls with tamping methods. At this time, a certain amount of wheat straw and mud can be mixed into the soil to make the adobe. After the adobe is dried, it will sleep the adobe wall. When building the wall, between Adobe tightly blocked with grass mud wall, inside and outside to wipe grass mud. The brick wall construction should first be laying the foundation, then you can wall construction to mortar overflowing, hook good brick, with gray face, both inside and outside the wall to avoid air leakage plastering. The hollow layer between the brick wall and the layer should not be too large or too small. The width of the general hollow is between 5-8 centimeters. Hollow can not be left to the end, every 3-4 meters, the brick will be connected to each layer, in order to improve the firmness of the wall. Hollow walls can be made of slag, pearlite and wheat straw as filler, or nothing. Only air insulation, no stuffing hollow wall, must be done without cracks. When the roof is opened, it is better to seal the top 30 centimeters with mud bran, so that the rear wall and the rear roof are closely connected to improve the thermal insulation performance.
