Hollow drainage ridge for flat dam strip-field

Abstract

The invention discloses a hollow drainage ridge for a flat dam strip-field. The hollow drainage ridge is a ridge which is built by casting a building material and of which the inner cavity is provided with a drainage sewer; a river of which the total capacity height is lower than a bottom line of a plough layer of a field along a line and the water at the tail is drained into a drop section through the underside of a transverse ridge is designed; drain holes of fields along the line are formed on two side walls of the ridge near a crossed field corner above the total capacity height; and the ridge crossed position with the drain hole is provided with a pit and cover plate, which exceeds a vicinity range of the tail drain hole of the ridge crossed position. The invention has the advantage that: the hollow drainage ridge has enough drop, quickly drains irrigation water and rainwater timely, reduces the flood discharge pressure of irrigation ditches to prevent rainstorm from flooding the field to avoid flooding crops, can reduce the loss of soil nutrients, effectively solves a problem of wet damage in the field timely to facilitate soil permeability, creates high yield conditions for the crops, does not influence irrigation from one field to another, can avoid a dispute of field flooding due to drainage, prevents drained water from being blocked by irrigation channel water or irrigating the field by mistake, has two purposes of the drainage sewer and an aisle ridge, drains water in a labor-saving and time-saving mode, and avoids the scouring of rainstorm and weed coverage of the field.

Description

technical field [0001] The invention relates to a field ridge with a drainage ditch in the inner cavity. Background technique [0002] Pingba Irrigation District has abundant water conditions, which is conducive to the development of a large number of economic production of vegetables in winter and spring. However, the terrain of Pingba is flat, and the drainage drop of most fields facing the irrigation canal or adjacent fields is higher than the bottom level of the plow layer of the field, and some fields even have no drainage drop, which does not have the good field factor of convenient drainage and irrigation. It leads to a large amount of soil nutrient loss, irrigation canals block drainage outlets or even mis-irrigate fields, soil is invaded by moisture, hinders air entry, hinders crop root extension and beneficial microbial activities, and insufficient flood discharge capacity of irrigation canals leads to heavy rains flooding large fields along the line. The above-me...
