A kind of coastal saline-alkali area heliogreenhouse collection rain is every salt water-storing device
Technical field
The utility model relates to agricultural planting water storage device, and particularly a kind of coastal saline-alkali area heliogreenhouse collection rain is every salt water-storing device.
Background technology
The irrigation water in coastal saline-alkali area is alkaline, be unsuitable for the demand of vegetable crop centering sour environment on the weak side, existing scheme is that the way that drops into acetic acid or citric acid in irrigation water source neutralizes, and takes a lot of work, to using the alkaline bad assurance of sour consumption of neutralization but operate; Take the solution of another defeated fresh water, also face the problem of secondary salinization in cost of investment height and water delivery process, existing greenhouse catchment of rainfall cell system is applied to general soil condition, can not effectively isolate saline and alkaline infiltration on the one hand, can conduct because of underground heat on the other hand, water temperature reduces fast, inapplicable on the ground at saline-alkali soil.
At present, utilize the soil of varieties in saline-alkali areas, beach, irrigation water is that saline and alkaline is high, be unsuitable for being worth the demand of higher industrial crops to less salt and neutral meta-acid environment, existing scheme is that the way that drops into acetic acid or citric acid in irrigation water source neutralizes, but operation is taken a lot of work, and to neutralizing the alkaline bad assurance of sour consumption, and does not remove the harm that salt content is high; The method of taking fresh water to carry, faces the problem of secondary salinization in the high and water delivery process of cost of investment, and existing collection rain reservoir is every salt leakage preventing structure, and fresh water enters behind pond because outside salinity permeates salinization; In addition, coastal region groundwater table is high, and soil moisture is large, thermal conductivity is strong, and in reservoir, water temperature is low, is unfavorable for crop winter growth, some areas adopt open water pool to shine water and heat up, and can cause falling into foreign material and growing green alga in pond, affect the unimpeded of slight irrigation pipeline.There is no practical fresh water collecting and storage facility, coastal saline-alkali can only be planted the crop of Salt And Alkali Tolerance on the ground, and Crop Planting Structure is single, and economic benefit is low.
