Problems solved by technology

[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.

Embodiment Construction

[0037] figure 1 , figure 2 It is a schematic diagram of the irrigation method for ridge-growing wheat

[0038] In practical application, the ridge-cropping wheat irrigation pipe 1 is held on the irrigation vehicle 2, and the multiple irrigation and drainage holes 1-2 of the irrigation pipe 1 correspond to the furrows of the wheat field one by one, and move along the direction of the furrows at a specified speed. For water supply, the edge of the wheat field and the ditch are set in the same direction as the water supply branch pipe 10, and the interface is evenly segmented on the water supply branch pipe, and one end is connected to the water supply pipe of the water source; the water inlet of the irrigation pipe is connected with the longitudinal pipe interface; The specified speed is advanced in stages to complete the whole ridge irrigation. The speed of the irrigation vehicle is determined according to the water demand of the crops in different periods: such as the water ...

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.
