Embodiment 1

[0031] Embodiment 1: as figure 1 shown.

[0032] When the field is level, or when the subdivision is horizontal, the hairy canal 2 passes through a central axis of the subdivision, and the two sides of the canal 2 lead to multiple water delivery ditches 3 according to the length of the subdivision. Extending to the edge of the partition, the water delivery ditch 3 runs through multiple irrigation ditches 1, and the irrigation ditch 1 is the inter-ditch field ridge 4. The crops are planted on the inter-ditch field ridge 4, and the irrigation water is introduced from the hair ditch 2. The canal 2 flows into the water delivery ditch 3 , then flows into the irrigation ditch 1 , and finally penetrates into the field ridge 4 between the ditches to realize crop irrigation.

Embodiment 2

[0033] Embodiment 2: as figure 1 shown.

[0034] When the partition has a certain slope, and the slope is not greater than 5°, the hair canal 2 is located on the central axis of each partition along the slope direction, and the two sides of the hair canal 2 are dug through with multiple water delivery ditches 2 parallel to each other. The water delivery ditch 3 extends to the edge of the corresponding partition.

Embodiment 3

[0035] Embodiment 3: as figure 2 shown.

[0036] When the slope of the partition is greater than 5°, the hair canal 2 is set on the side of the slope of the partition, and a cross-block is set in the direction of the channel of the water delivery ditch 3, and the irrigation ditch 1 is set parallel to the slope contour line. Or it is set at an acute angle with the contour line of the slope, and the slope faces the downhill direction.

Abstract

The invention relates to a film hole furrow irrigation method for saline-alkali land soil, and a mulching film puncher. The film hole furrow irrigation method includes arranging a field water deliverysystem, laying a plastic film in an irrigation ditch, opening multiple rows of film holes in the side wall of the irrigation ditch, and injecting water into a sublateral canal, a water delivery ditchand the irrigation ditch to irrigate crops on ridges between the ditches. The mulching film puncher comprises a connecting rod and a supporting rod which are arranged in a coaxially sleeved mode. A punching cylinder is connected to the lower end of the supporting rod in a coaxially communicated mode. A punching ring cutter is coaxially arranged at the lower end of the punching cylinder. The lowerend of the connecting rod extends into the punching cylinder, and is provided with a sliding soil compaction disc. The upper end of the connecting rod extends above the supporting rod, and is provided with a press plate. When the press plate is pressed down to the top of the supporting rod, the sliding soil compaction disc moves downwards to be close to a plane where the punching ring cutter is located. The film hole furrow irrigation method and the mulching film puncher have the advantages that two irrigation forms, namely furrow irrigation and drip irrigation, are integrated, so that water-saving irrigation is achieved while problems, such as uneven irrigation frequently occurring in furrow irrigation and salt accumulation of soil surface layers in drip irrigation, are solved.

Description

technical field [0001] The invention relates to a film hole furrow irrigation method for saline-alkali soil and a film hole puncher, belonging to the technical field of agricultural water and soil engineering. Background technique [0002] Both furrow irrigation and drip irrigation are farmland water-saving irrigation technologies that use water resources efficiently. In recent years, they have been widely used in many areas of our country, especially in saline-alkali areas where water resources are scarce. Compared with traditional full-scale irrigation, furrow irrigation has the advantage that it will not damage the soil structure near the roots of crops, will not cause field compaction, and can reduce soil evaporation loss. It is suitable for row crops with wide row spacing, but furrow irrigation has poor adaptability to terrain. The field occupies a large area, the ditch surface is easy to collapse and other shortcomings, and in the soil environment with poor water perme...
