Problems solved by technology

Although this portable device for simulating underground drip irrigation in the field can accurately and easily control the flow or flow rate under undisturbed soil conditions, the capacity of the container bottle 2 has not been specifically designed according to the specific ecological conditions of the region and the water demand of specific plants. There are major limitations in

Embodiment approach

[0026] (1) The volume and water storage capacity of a single water storage bucket A1 can be adjusted according to the type and quantity of drip irrigation plants. The water requirements of several common tree species at different tree ages in desert or Gobi areas are shown in Table 1 below:

[0027] Table 1

[0028]

[0029] like Figure 4 As shown, if each water storage bucket A1 is drip-irrigated to four plants, and the four plants are a young Xinjiang poplar, a middle-aged large-leaf ash, a mature large-leaf elm and a young elm, then according to the data in Table 1, the average annual water requirement of each plant in the growth period of these four plants can be: (640+750+1310+660)÷4=840mm. In the desert or Gobi area, if the annual water demand of each plant in the growth period is 1300mm, the water storage capacity of the storage tank A1 is ≥1300mm×1m 2 ×Number of drip irrigation plants, and the number of outlet pipes A5 is also adjusted with the change of the num...

Embodiment 1

[0038] like figure 2 and image 3 As shown in the figure, an independent drip irrigation device based on plant water demand in desert or Gobi area is used for drip irrigation of four plants in desert or Gobi area at the same time, and its specific structure includes: water storage bucket A1, ventilation pipe A3, filter screen A4, water outlet A5, control valve A6, flow rate controller A7, bracket A8 and dripper A9. The water storage bucket A1 and the water outlet pipe A5; the water storage bucket A1 has a bottom circle radius of 0.75m, a height of 2.9m, and a volume of 5.2m 3 The cylindrical container, the four water outlet pipes A5 are evenly distributed on the circumference of the lower part of the water storage bucket A1, and each water outlet pipe A5 only carries out drip irrigation to one plant, and the corresponding water outlet pipes A5 made by each plant are different. The flow rate of the outlet pipe A5 is 0.13L / h, which is calculated based on the annual water dema...

Abstract

The invention discloses an independent drip irrigation device on the basis of water demands of plants in desert or gobi regions. The independent drip irrigation device comprises a water storage bucketand water outlet pipes. The water outlet pipes are arranged on the lower portion of the water storage bucket, drip irrigation can be carried out on a single corresponding plant by each water outlet pipe, and the flow velocity of each water outlet pipe is 0.13L/h; the water storage capacity of the water storage bucket is higher than or equal to a product of the annual water demand of each plant inthe growing period, 1 m<2> and the number of plants required to be subjected to drip irrigation. The independent drip irrigation device has the advantages that the independent drip irrigation devicecan be independently operated for a year without labor, the water demands of the plants in integral growing seasons can be met, and manual water volume inspection and repeated irrigation can be omitted in the periods; the cost for laying water delivery pipelines from water source regions can be saved, and accordingly the independent drip irrigation device is extremely high in practicality for thedesert or gobi regions with vast territories and severe water shortage.

Description

technical field [0001] The invention relates to the technical field of plant irrigation in desert or Gobi areas, in particular to an independent drip irrigation device based on the water demand of plants in desert or Gobi areas. Background technique [0002] Drip irrigation is an irrigation method with better water-saving effect in the world today. Drip irrigation is to transport water slowly, uniformly, moderately and accurately to the soil surface near the root of the crop through the low-pressure pipeline system and the dripper installed on the final pipeline according to the water requirements of the crop, and infiltrate the most developed area of ​​the root system. Therefore, the soil in the active root zone can maintain the best water state and meet the water requirements of crops. Compared with traditional furrow irrigation and flood irrigation, drip irrigation has the advantages of saving water, labor, maintaining soil structure, and reducing the loss of nutrients. ...
