Salinization prevention system of seedling culture base

Abstract

The invention discloses a salinization prevention system for a seedling raising base, which comprises a bottom plate and a seedling raising base. A booster pump switch is arranged on one side of the upper surface of the bottom plate. The input end of the booster pump switch is electrically connected with the output end of an external power supply. The bottom plate A pool is provided on the left side of the upper surface of the pool, and a water inlet pipe is provided on the side surface of the pool, and the water inlet pipe communicates with the pool. An ion exchange membrane is arranged inside the pool, and the ion exchange membrane is close to the water inlet pipe. A fixing seat is provided on the right side of the upper surface of the bottom plate. A booster pump is arranged on the upper surface of the fixed seat, the input end of the booster pump is electrically connected with the output end of the booster pump switch, the inlet end of the booster pump communicates with the pool through the first conduit, and a valve is provided in the middle of the first conduit , the outlet end of the booster pump is connected with the second conduit. The anti-salinization system of the nursery base has a simple structure and is convenient to use. The groundwater is treated and then irrigated, and the spraying and irrigation is uniform. Moreover, a drainage ditch is also provided, which can effectively prevent the salinization of the nursery base.

Description

technical field [0001] The invention relates to the technical field of garden planting, in particular to a salinization prevention system for seedling raising bases. Background technique [0002] Saline-alkali land refers to the salt contained in the soil that affects the normal growth of crops. According to incomplete statistics from UNESCO and FAO, the area of ​​saline-alkali land in the world is 954.38 million hectares, of which 99.13 million hectares are in my country. The formation of alkaline soil and alkalized soil in my country is mostly related to the accumulation of carbonate in the soil, so the degree of alkalization is generally high, and plants in severe saline-alkali soil areas can hardly survive. When the existing seedling bases use groundwater to irrigate the soil, the groundwater is not treated. After irrigation, the salt accumulates with the evaporation of the water, forming a saline-alkali land. In addition, if it is a depression, there is no drainage outl...

AI Technical Summary

Problems solved by technology

When the existing seedling bases use groundwater to irrigate the soil, the groundwater is not treated. After irrigation, the salt accumulates as the water evaporates, forming a saline-alkali land. In addition, if it is a depression, there is no drainage outlet, and after the water evaporates, the salt will remain, forming saline land
