Problems solved by technology

[0002] Under the condition that my country's water resources are becoming increasingly tense and soil compaction is gradually intensifying, how to effectively save water in agricultural production, improve water use efficiency and prevent soil salinization has become an important issue. Currently, the main water-saving irrigation methods used are sprinkler irrigation and drip irrigation. Although these measures have achieved certain results, there are still problems such as waste of water resources, low water use efficiency of plant roots and blockage of drip irrigation pipes.
[0003] The Chinese invention patent (publication number CN101248743A) provides a high ridge and nutrient solution drip irrigation cultivation technology. This technology uses intermittent irrigation, but it cannot accurately control the water consumption according to the soil environment and the requirements of the planted plants, and still causes water resources. Waste and uneven distribution, while prone to drip clogging
[0004] The Chinese invention patent (publication number CN102845274A) provides a new type of plant irrigation method. This method is easy to cause the soil to return to alkali, and the plant species are single. If the depth is changed, the labor cost will be greatly increased.

Embodiment 1

[0041] Plant neutral plants in sandy soil, because the soil has a lot of sand, coarse particles, fast water seepage, and poor water retention performance. The dripping speed is set at 90 times / min, and the interval between two consecutive drippings is set at short intervals. for 20 minutes.

[0042] In this embodiment, the continuous irrigation time is represented by T each time, T=(X / W)t, T=900s, X=67.5ml, W=0.05ml, t=2 / 3s.

[0043] In the present embodiment, the fixed interval time (intermittent time) of stopping water after each continuous drip irrigation is represented by Y, Y=1233s, N / M=0.8, X=67.5ml, E=27.5ml, V 1 =0.014ml / s, V 2 = 0.001 ml / s.

Embodiment 2

[0045] Neutral plants are planted in clay soil with low sand content, fine particles, slow water seepage speed, and good water retention performance. The slow drip speed is set at 60 times / min, and the short interval between two continuous drips is set at 30 minutes.

[0046] In this embodiment, the continuous irrigation time is represented by T each time, T=(X / W)t, T=2400s, X=96ml, W=0.04ml, t=1s.

[0047] In the present embodiment, the fixed interval time (intermittent time) of stopping water after each continuous drip irrigation is represented by Y, Y=3600s, N / M=1 / 3, X=96ml, E=42ml, V 1 =0.002ml / s, V 2 = 0.001 ml / s.

[0048] The results of the examples show that the present invention can arbitrarily adjust the amount of irrigation water according to soil type and plant species, improve plant water use efficiency, save water, and prevent soil salinization.

Abstract

The invention relates to the field of plant irrigation, in particular to an intermittent drip irrigation method. The pulse generator is installed at the water inlet of the titration system as a pulse regulating water pressure device, and is closely combined with the time-period intermittent irrigation method to form an irrigation system combining pulse pressure regulation and time-division intermittent irrigation. According to different plant types and characteristics, as well as different soil types, the present invention precisely controls the amount of water, improves plant water use efficiency, and saves water; the drip irrigation method adopted is to effectively combine pulse technology with time-based intermittent drip irrigation. The size controls the dripping speed and intermittent time, and precisely controls the water consumption, so that the water content in the root soil of the plants below the dripping port can reach the best state, and it can effectively solve the phenomenon of water resource waste and soil back-salt phenomenon, while reducing the blocking of the dripping port.
