Every year, many vegetable farmers renovate the old sheds that have been planted for many years. However, the renovation of the old sheds will generally increase. Due to the restrictions of the plots, the distance from the adjacent sheds will become narrower. problem. The original construction of the renovation of the greenhouse, you should pay attention to three points:
Attention to drainage
After the renovation, the new shed will be taller, and the distance between adjacent sheds will naturally be narrow. For example, the distance between some newly built sheds and the former sheds is less than 3 meters, so that the drainage ditch cannot be set. If you encounter more precipitation, it is likely to flood the shed.
It is recommended to dig a drainage ditch in the front of the shed. The width of the drainage ditch depends on the distance between the front face and the front shed, but it must be deeper than the ground in the shed. If there is a deep ditch around the shed, it is recommended that the ditch be dug and connected to the surrounding ditch with a drain. If the front of the shed is deep, you should also prepare a drainage pump such as a water pump to prevent the water from being discharged after the rainstorm.
Pay attention to the installation and use of the roller blind machine
Due to the small distance between the shed and the shed, the installation of the pole roller blind or the bridge roller blind is very crowded, such as the use of the pole roller blind machine, after the straw curtain is lowered, due to its small angle, the whole The struts may tilt south and are in a dangerous state. Therefore, when the old shed is rebuilt, it is recommended to install a light and short roller type roller blind machine when the shed spacing is not suitable for the installation of the pole roller blind or the bridge roller blind.
Pay attention to the front face shading
In order to improve the insulation capacity of the shed, the vegetable farmer had to dig deep under the shed to ensure the amount of soil used for the wall. As a result, the planting level in the shed is low, which is unfavorable for the growth of vegetables at the front face. In addition, it is very close to the neighboring shed, and the vegetables at the face before the deep winter festival will be insufficiently illuminated.
It is recommended to keep the low front face after the renovation of the greenhouse, to avoid the front face shading, and the shading of the front shed, you should take specific measures to give special care to the vegetables, such as installing the fill light in the first two rows of columns, make up Warm lights, etc., to improve the light temperature conditions of the front face. In addition, it is also a good way to set the channel or transport channel at the front face.
