Method and equipment for irrigating ridge-planted wheat

Abstract

A water-saving irrigation method and its system for the wheat on the ridged land features that the water-supplying branch pipes with uniformly arranged jointer are arranged in furrow direction and connected to water source pipe, and a movable irrigation vehicle is arranged in furrow direction, which has the irrigation pipe with the irrigation holes connected to the jointers of said branch pipes.

Description

technical field [0001] The invention relates to a method and device for irrigating wheat in ridge cultivation, belonging to the technical field of agricultural irrigation. Background technique [0002] At present, the no-tillage sowing technology of wheat is widely promoted in the country. While realizing the direct return of corn stalks to the field, ditching is used to sow wheat. The soil turned up from the ditching is buried in the soil between the wheat rows to form furrows, and the wheat is sown in the furrows. , the wheat field of this kind of sowing method, using the sprinkler irrigation technology in the existing irrigation technology is more water-saving, but the equipment investment is large, and because wheat is a long-rooted crop, it needs deep soil water supply in the later stage of growth, and the irrigation amount of sprinkler irrigation is small. The irrigation depth is shallow. On the one hand, it does not take advantage of the deep growth of the crop root s...

[0002] At present, the no-tillage sowing technology of wheat is widely promoted in the country. While realizing the direct return of corn stalks to the field, ditching is used to sow wheat. The soil turned up from the ditching is buried in the soil between the wheat rows to form furrows, and the wheat is sown in the furrows. , the wheat field of this kind of sowing method, using the sprinkler irrigation technology in the existing irrigation technology is more water-saving, but the equipment investment is large, and because wheat is a long-rooted crop, it needs deep soil water supply in the later stage of growth, and the irrigation amount of sprinkler irrigation is small. The irrigation depth is shallow. On the one hand, it does not take advantage of the deep growth of the crop root system, which is easy to cause the late lodging of wheat. On the other hand, the drift loss of sprinkler irrigation is relatively large. In strong winds and dry weather, the evaporation loss of water droplets in the air can reach about 10%.

[0003] At present, the ground flood irrigation method is often used. Due to the existence of ridges and furrows, the irrigation volume cannot be effectively controlled, and the water consumption is large, which wastes water resources. Field dry farming urgently needs an irrigation method and device that can control the irrigation volume with relatively low investment.
