Small-scale corn irrigation method and special facility

Abstract

The invention relates to a small-scale corn irrigation method and a special facility, in particular to a small-scale irrigation method for corn germination water and a special facility, and belongs to the technical field of agricultural water saving. The irrigation method comprises the following steps of: (1) sowing corn according to the line spacing of 600 millimeters and the plant spacing of 250 millimeters; (2) when the corn is sowed, spreading irrigation water storage bands capable of quantitatively storing water and seeping water to a field between corn rows; (3) after the corn is sowed, filling water into the irrigation water storage bands; and (4) when the water filling quantity of each irrigation water storage band reaches 0.015 cubic meter per meter, stopping filling the water into the irrigation water storage bands. By the irrigation method, the consumption of the corn germination water can be reduced, the corn is germinated in advance, and the yield is increased; the scale of the irrigated water can be freely regulated and controlled, so that the utilization efficiency of the irrigated water is improved; and the special equipment is simple in structure, convenient to use, energy-saving, water-saving and low in cost.

Description

technical field [0001] The invention relates to a small-quantity irrigation method and special facilities for corn, in particular to a small-quantity irrigation method and special facilities for corn seedling emergence water, and belongs to the technical field of agricultural water saving. Background technique [0002] The sooner or later the emergence of summer maize after sowing directly affects its yield. Usually, summer maize is sown immediately after winter wheat is harvested. [0003] At present, the irrigation method used for corn seedling emergence is usually border irrigation, coupled with the existence of straw after wheat harvest, the water consumption for one irrigation is large, reaching 70-100mm; due to the large amount of irrigation, the ground evaporates and loses a lot of water, resulting in a waste of irrigation water At the same time, due to the large amount of irrigation per unit area, the irrigation cycle is long, and the emergence of corn is delayed due...

[0003] The current irrigation method used for corn seedling emergence is usually border irrigation, coupled with the existence of straw after wheat harvest, the water consumption for one irrigation is large, reaching 70-100mm; due to the large amount of irrigation, the ground evaporates and loses a lot of water, resulting in a waste of irrigation water At the same time, due to the large amount of irrigation per unit area, the irrigation period is long, and the corn seedling emergence is delayed due to the inability to irrigate in time after the corn is sown, which affects the yield
