Problems solved by technology

[0008] In the case of the overall shortage of water resources in my country, the water used for agricultural irrigation is correspondingly reduced or even insufficient. If you rely solely on tap water to irrigate farmland, the cost is relatively expensive. According to the water supply price issued by the Qingdao Municipal Price Bureau, the water consumption per cubic meter will increase to 2.5-7 yuan per cubic meter. Not equal; groundwater exploitation is one of the methods to solve the problem of water use, but it

Embodiment 1

[0039] Example 1 A rain-collecting and salt-separating solar greenhouse for vegetable production in saline-alkaline areas

[0040] The rain-collecting and salt-separating solar greenhouse used for the production of vegetables in saline-alkali areas provided by this embodiment, such as figure 2Shown, described greenhouse comprises front wall 19, rear wall 18 and greenhouse film 21, and described front wall 19 is positioned at south side, and described rear wall 18 is positioned at north side, as figure 2 As shown, the south and north mentioned in the embodiment of this specification and the drawings of the specification are all related to figure 2 The south and north directions marked in are consistent. The structural design of the solar greenhouse includes the design of the rain-collecting structure of the greenhouse and the design of the soil-salt isolation and salt-reduction structure of the greenhouse.

Embodiment 2

[0077] Example 2. Application of rain-collecting and salt-separating solar greenhouse

[0078] like figure 1 and 2 As shown, using this set of devices can solve the problems of poor fresh water resources and high salinity in soil for saline-alkali land. The present invention designs the rear slope to be a movable rear slope structure, which is composed of an everted movable rear slope rain collection structure, an inclined earth slope rain collection structure, a front roof rain collection structure, a water collection pipe 6 and a water storage tank 2. During natural rainfall, open the back slope 14 of the rain-collecting type solar greenhouse, and a part of the rainwater can directly wash away the saline-alkali soil, and the other part of the rainwater can be accumulated along the water-collecting pipe 6. Through three rain-collecting methods, the rainwater can be accumulated together and flow into the underground water storage together. Pool 2 is used as soil washing brin...

Abstract

The invention provides a rainwater collection and salt isolation type solar greenhouse used for vegetable production in a saline and alkaline region. The greenhouse comprises a front wall and a rear wall, wherein a greenhouse film is arranged between the front wall and the rear wall, a skylight device is arranged at the top end of the rear wall and connected with an outward turning movable rear slope, and a triangular support is fixedly arranged on the rear wall; an inclined soil slope is arranged on the outer side of the front wall, and a water storage channel is formed between the inclined soil slope and the front wall; a rainwater collecting pipe is arranged on the rear wall; a water collecting pipeline is arranged underground in the greenhouse. The rainwater collection and salt isolation type solar greenhouse can simultaneously realize fresh water supply and effective utilization of soil in situ, integrates a rainwater collection technology and a salt reduction technology to form an integrated technology system and is convenient and effective. The movable rear slope design is disclosed, and the greenhouse has the advantages of being capable of collecting rainwater, facilitatingopening, reducing indoor humidity of the greenhouse and avoiding affecting normal production of vegetables and the like.

Description

technical field [0001] The invention belongs to the technical field of agricultural production, and in particular relates to a rain-collecting and salt-isolation solar greenhouse used for vegetable production in saline-alkali areas. Background technique [0002] Land resources are the foundation of agricultural production, but soil salinization limits the efficient development of agriculture and the effective use of land resources. In my country, saline-alkali land is widely distributed, especially in coastal cities and islands, where the saline-alkali land is huge, and the soil has high salinity, which makes it impossible to grow a series of agricultural products such as vegetables and fruits with high output value. At present, traditional solar greenhouses are mainly used in saline-alkali land, and vegetables are produced after the soil is improved. The back slope is a fixed brick wall structure, which cannot be rotated or opened. In addition, the phenomenon of saline-alk...
