Drop irrigation device extracting water from air for arid region trees

Abstract

The invention discloses a drop irrigation device extracting water from air for arid region trees and relates to a method combining for a drop irrigation method and a mulching film covering method to promote the trees to keep alive. Moisture evaporated inside a plastic shed and moisture of external rain, snow and frost are gathered into roots of the trees, so that water and soil losses are reduced; weed growth is restrained; ventilation and preservation of soil moisture are achieved; earth temperature is increased; hard light is reduced; day and night and seasonal variation ranges of the earth temperature are lessened; the contents of available nutrients and organic matter are increased; and the survival rate of a sapling is improved, and the drop irrigation device is favorable for absorbing and growing of trees.

Description

[0001] Technical field: [0002] This embodiment is used for tree root water supply, and belongs to the subcategory of root water supply (A01G 29 / 00) of the major watering category of the Agricultural Division of the Ministry of Human Living Necessities. [0003] Background technique: [0004] In arid areas, the temperature difference between day and night is large, the amount of precipitation is small, the rate of precipitation change is large, the distribution is uneven within a year, the air is dry, and the evaporation on the surface is large, which seriously affects the development of forest trees. Since the trees in arid areas do not have the conditions for canal irrigation, drip irrigation is used in many places to effectively improve the water utilization rate. However, drip irrigation in remote arid areas requires a large investment in construction, requiring deep wells, erecting water irrigation, and laying many pipelines. It is not suitable for the berm tree or windbr...

Problems solved by technology

Since the trees in arid areas do not have the conditions for canal irrigation, drip irrigation is used in many places to effectively improve the water utilization rate. However, drip irrigation in remote arid areas requires a large investment in construction, requiring deep wells, erecting water irrigation, and laying many pipelines. It is not suitable for the berm tree or windbreak tree along the road because the route is far away, and it is not suitable for the dropper to freeze during the freezing period; some places have adopted the plastic film covering method, which can prevent soil erosion, increase ground temperature, reduce evaporation, and shrink The diurnal and seasonal variation of ground temperature is beneficial to the growth of trees, but there are also problems such as easy growth of weeds, high temperature at noon, poor air permeability, and easy rot of the roots.
