Description

TECHNICAL FIELD

[0001] The utility model relates to agricultural technology field especially relates to an auxiliary device for preventing and treating plant rainfall salt harm. BACKGROUND

[0002] In arid and semi-arid regions, precipitation is rare, and atmospheric evaporation is extremely strong. Agriculture completely relies on irrigation, but most of the soil moisture is lost due to evaporation. After water evaporation, salt remains in the soil surface, i.e. salt surface aggregation. If the development is serious, it will cause secondary salinization of the surface soil, and the physicochemical properties will deteriorate. If a small amount of rainfall is encountered, the salt in the soil surface can be leached to the plant root zone, causing plant salt damage. In saline water irrigated ecological forest land, salt surface aggregation is more intense, and a salt crust layer is generally formed in the soil surface. Plant salt damage caused by rainfall is also more serious. The Tarim Desert Highway Shelterbelt Ecological Engineering uses underground saline water irrigation, and the irrigation water mineralization degree reaches 3-28g / L. The salt in the soil surface accumulates in large quantities, and the salt crust develops widely. The sudden heavy rainfall in spring and summer caused regional salt damage to young sand carob (planted for 1-2 years) with poor salt tolerance, poor growth, and even death.

[0003] The common method for preventing and treating soil surface salt accumulation is to irrigate with large amounts of water regularly to wash the salt, and to leach the excess salt in the surface and plant root layer to the outside of the plant root layer. The common method for preventing and treating plant rainfall salt damage is to irrigate at the same time as rainfall, dilute the salt concentration of the soil solution, and protect the plants. These methods have good prevention and treatment effects, but a large amount of water is needed to achieve salt leaching. For rainfall salt damage prevention and treatment in irrigation areas, this method also has certain operational difficulties: due to the need for a certain time for rotation irrigation between irrigation areas, once a heavy rain occurs, water and salt will quickly infiltrate, and salt damage will occur before some irrigation areas have had a chance to irrigate.

[0004] In addition, the soil surface salt crust peeling method can also prevent and treat soil surface salt accumulation and rainfall salt damage, but the effective prevention and treatment time is short, and the salt crust will form again after a certain period of time. Moreover, the operation is labor-intensive, and is only suitable for small areas of forest land, and is difficult to operate practically for large areas of ecological engineering.

[0005] Therefore, it is necessary to bury the drainage branch pipe in the drip irrigation structure underground to reduce the amount of water evaporation, extend the uniformly arranged water spraying vertical pipes on the drainage branch pipe to the ground, arrange the water spraying vertical pipes beside the plant root system, expose the upper end of the water spraying vertical pipes to the ground, spray water to the plant root system to dilute the salt and alkali brought by rainfall, avoid the salt and alkali crust from causing plant dehydration and death, and reduce plant rainfall salt damage prevention and treatment devices.

[0006] However, the general drip irrigation nozzle has a specified water spraying direction, so the range of flushing the salt and alkali in the soil surface of the plant root system is limited, and the prevention and treatment efficiency of rainfall salt damage needs to be improved.
