[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 drips 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 a novel intermittent drop irrigation method. A pulse generator serving as a pulse water pressure adjusting device is arranged at a water inlet of a drop irrigation system and is tightly combined with a day-parting intermittent irrigation method to form an irrigation system with pulse pressure adjusting and day-parting intermittent irrigation to be combined. The novel intermittent drop irrigation method can accurately control the water amount according to different plant types and characteristics and different soil types. Thus, the water using efficiency of plants is improved, and water is saved. The drop irrigation method effectively combines a pulse technique with the day-parting intermittent drop irrigation method. The water dropping speed and the intermittent time can be controlled by adjusting the pulse pressure. Thus, the water using amount can be accurately controlled, the water content of plant root soil under water dropping openings can be in the optimal state, and the problems of water resource waste and salt accumulation of soil can be effectively solved. Meanwhile, plug of the water dropping openings can be reduced.
