Brackish water irrigation method for lyciumbarbarumin salinized irrigation area

Abstract

The embodiment of the invention relates to a brackish water irrigation method for lyciumbarbarumin salinized irrigation areas, and relates to an irrigation technique for lyciumbarbarumin salinized irrigation areas. On the premise that the content of salt of soil is reduced, the requirements of lyciumbarbarumon water in the growth period can be met, and at the same time the medicinal quality of lyciumbarbarum is effectively improved. The brackish water irrigation method comprises the following steps: irrigating by using yellow river canal water of which the mineralization degree is 0.4-0.8g / l for first irrigation and second irrigation, irrigating by using brackish water of which the mineralization degree is 3-4g / l for third irrigation and fourth irrigation, and irrigating by using yellow river canal water of which the mineralization degree is 0.4-0.8g / l for fifth irrigation.

Description

technical field [0001] The invention relates to the irrigation technology of wolfberry in salinized irrigation areas, in particular to a brackish water irrigation method for wolfberry in salinized irrigation areas. Background technique [0002] The lower reaches of the Hetao Irrigation Area in Inner Mongolia belong to the original Yellow River channel, and the buried depth of the groundwater level is relatively shallow. Due to the long-term history of farmland irrigation, the local groundwater has a high degree of salinity, serious soil salinization, and the surface is prone to salt accumulation, and the distribution is uneven. Seriously affected the local agricultural production. Pioneer Town of Urad Front Banner is known as the No. 1 Town of Goji Berry in Inner Mongolia. Due to geographical location and other factors, the local agricultural irrigation adopts a combination of wells and canals. However, because the salinity of many local irrigation groundwater is almost salt...

[0002] The lower reaches of the Hetao Irrigation Area in Inner Mongolia belong to the original Yellow River channel, and the buried depth of the groundwater level is relatively shallow. Due to the long-term history of farmland irrigation, the local groundwater has a high degree of salinity, serious soil salinization, and the surface is prone to salt accumulation, and the distribution is uneven. Seriously affected the local agricultural production

Pioneer Town of Urad Front Banner is known as the No. 1 Town of Goji Berry in Inner Mongolia. Due to geographical location and other factors, the local agricultural irrigation adopts a combination of wells and canals. However, because the salinity of many local irrigation groundwater is almost salt water (>5g / l), the multi-year salt water irrigation mode in the well irrigation area has led to a further increase in the salinity of the local groundwater, and the salt content of the cultivated layer has also increased. A series of problems such as surface salt accumulation and land degradation have seriously affected The yield and quality of wolfberry
