Novel intermittent drop irrigation method

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.

Description

technical field [0001] The invention relates to the field of plant irrigation, in particular to a novel intermittent drip irrigation method. Background technique [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.

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.
