Problems solved by technology

[0003] At present, the utilization efficiency of condensed water by plants in arid desert areas is still in a spontaneous state, and the utilization of condensed water on bare ground under extreme drought conditions is mostly ineffective and dissipated; at the same time, it is difficult for plants in arid desert areas to obtain effective Water supply, enduring the survival stress brought by water shortage all year round

Embodiment 1

[0027]First, make a water utilization device in the arid desert area, seal the bottom of the shaft 6, and symmetrically take the shaft 6 as the center of the shaft 6 at the heights of 1.12m, 1.24m, 1.36m, 1.60m and 2.5m Fix keel 1, keel 2, keel 3, keel 4 and keel 5 to form 5 circles with different radii. The keel radii are 0.3m for keel 1, 0.5m for keel 2, 1m for keel 3 and 1.5m for keel 4. , The keel 5 is 2m, and the circular nylon screen with a radius of 0.3m is fixed on the keel 1 to form an artificial coagulation surface 7, and then the nylon screen is made into 4 hollow rings and fixed on the keel 2 and keel 3 , keel 4 and keel 5 respectively form artificial coagulation surface 8, artificial coagulation surface 9, artificial coagulation surface 10 and artificial coagulation surface 11, the inner circle radius of the hollow ring is 0.3m for artificial coagulation surface 8, 9 is 0.5m, artificial condensation surface 10 is 1m, and artificial condensation surface 11 is 1.5m....

Embodiment 2

[0034] Manufacturing device is carried out according to embodiment 1;

[0035] Collect fallen leaves from local plants in arid desert areas, soak them in fresh water for 24 hours, take them out, spread them 30cm below the soil layer with a thickness of 4cm, and bury them with the original soil;

[0036] During the plant growth period, artificial sprinkler irrigation was carried out in late March to stimulate the soil seed bank, and the artificial sprinkler irrigation was every 1.5m 2 Area spraying with 400ml water;

[0037] After ensuring that the seeds germinate, embed the axis 6 of the plant water utilization device in the arid desert area into the treated soil at a depth of 100 cm, and leave other parts exposed, with an interval of 2 m between each device;

[0038] From 20:00 in the evening to 6:00 in the morning of the next day, condensed water was formed on the surface of the soil and the surface of the nylon screen in the device. The height is 0-12cm to replenish water...

Embodiment 3

[0041] Manufacturing device is carried out according to embodiment 1;

[0042] Collect fallen leaves from local plants in arid desert areas, soak them in fresh water for 24 hours, take them out, spread them 30cm below the soil layer with a thickness of 5cm, and bury them with the original soil;

[0043] During the plant growth period, artificial sprinkler irrigation was carried out in late March to stimulate the soil seed bank, and the artificial sprinkler irrigation was every 1.5m 2 Area spraying with 500ml water;

[0044] After ensuring that the seeds germinate, bury the axis 6 of the plant water utilization device in the arid desert area into the treated soil at a depth of 100cm, and leave other parts exposed, with an interval of 1.5m between each device;

[0045] From 20:00 in the evening to 6:00 in the morning of the next day, condensed water was formed on the surface of the soil and the surface of the nylon screen in the device. The height is 0-12cm to replenish water....

Abstract

The invention relates to a quick method for relieving water deficit of plants in arid desert areas. According to the method, the stimulation effect of water supply on a soil seed bank, the range in which soil condensate appears easily, the influence of a canopy structure on condensed water and a condensing surface made of dense nylon screens are used, so that the formation of hydroscopic water in different ranges, atmospheric water vapor condensed water and soil water vapor condensed water is promoted, an effective water supply is provided for the germination and seedling emergence of the soil seed bank, the plants are helped to overcome drought, and then the aim of relieving the water deficit of the plants in the arid desert areas is fulfilled. By the method, the survival rate of annual plants in the arid desert areas in which the amount of precipitation is less than 150mm, the amount of evaporation is more than 2,000mm and the groundwater depth is large (3 to 4m) is improved, and the invalid dissipation of the condensed water is avoided.

Description

technical field [0001] The invention relates to a technology of a quick method for alleviating water shortage of plants in arid desert areas, in particular to a quick method for improving the collection and utilization of condensed water in arid desert areas. Background technique [0002] The process of water changing from vapor state to liquid state is called condensation, and the formed water is called condensed water, including natural condensed water and artificial condensed water. Natural condensed water refers to the condensation of water vapor in the atmosphere directly on the ground or on the surface of objects and in low altitudes, such as frost, dew, fog, and rime, also known as horizontal precipitation. The condensed water mentioned in the present invention mainly includes dew soil condensed water. Dew refers to the product of condensation of water vapor in the atmosphere to a certain surface after radiation cooling; soil condensation water refers to the condensa...
