a nursery shed

Abstract

The invention discloses a seedling raising greenhouse and belongs to the field of planting device. The seedling raising greenhouse comprises supporting columns inserted and buried in soil, a roof, a sun-shading layer and an automatic water supply system. The supporting columns are distributed on the periphery of seedling raising land. The upper ends of the supporting columns are connected with theroof, spraying pipes are installed on the roof, spraying heads are arranged on the spraying pipes, and the spraying pipes are connected with a first water pump through a first pipeline. The sun-shading layer is a sun-shading net, is arranged under the roof and is parallel to the seedling raising land. The automatic water supply system comprises a second water pump, a second pipeline and water spraying pipes, wherein one end of the second pipeline is connected with the water spraying pipes, the other end of the second pipeline is connected with the second water pump, the water spraying pipes are laid in the seedling raising land, atomizing spray heads are arranged on the water spraying pipes, the first water pump is connected with an impounding reservoir, the second water pump is connectedwith the impounding reservoir and a pesticide and fertilizer pond. The seedling raising greenhouse can quickly and effectively control the temperature, humidity and lighting intensity in the greenhouse and can also provide sufficient nutrients for seedlings in the seedling raising greenhouse and effectively prevent and control diseases and pests.

Description

technical field [0001] The invention belongs to the field of planting equipment, and in particular relates to a seedling raising shed. Background technique [0002] At present, most of the seedling sheds are a frame-covered structure with thermal insulation properties. They use a bamboo or steel structure skeleton, and one or more layers of thermal insulation plastic film are covered on the skeleton, thus forming a greenhouse space. However, the plastic film structure not only has poor sunshade effect, but also has poor air permeability. When there is sufficient sunlight during the day, especially in hot summer, the temperature inside the shed will continue to rise, and the highest temperature can reach 50°C. Crop growth is extremely unfavorable, and even a large area of ​​death may occur. [0003] According to investigations, problems such as irregular seed emergence, uneven growth, rotten seedlings, and burnt seedlings often occur in the process of growing seedlings in gr...

Problems solved by technology

However, the plastic film structure not only has poor sunshade effect, but also has poor air permeability. When there is sufficient sunlight during the day, especially in hot summer, the temperature inside the shed will continue to rise, and the highest temperature can reach 50°C. Crop growth is extremely unfavorable, and even large areas of death may occur

[0003] According to investigations, problems such as irregular seed emergence, uneven growth, rotten seedlings, and burnt seedlings often occur in the process of growing seedlings in greenhouses, which are related to uneven temperature, humidity, and illuminance in the greenhouse.

At present, the seedling sheds have a better heat preservation effect in winter seedlings, but they fail to achieve timely and effective ventilation, heat dissipation, shading, cooling, etc. during summer seedlings, and cannot achieve the environmental conditions suitable for plants in the seedling stage. , external environmental factors have a great influence on the growth of seedlings in the shed, which in turn makes the yield, quality and growth cycle of the plants not guaranteed, resulting in a large reduction in seedling production and huge losses

[0004] At present, there are also seedling sheds that are cooled manually, usually by spraying water or uncovering the film to let the air out. However, this method is labor-intensive, and the operation is cumbersome, and it cannot avoid the scorching sun. In addition, there are also intelligent cooling through automatic monitoring, but The cost of this method is very high, and most growers cannot accept it
