Narrow-row-spacing drilling close planting crop micro-spraying hose efficient sprinkling irrigation method

Abstract

A narrow-row-spacing drilling close planting crop micro-spraying hose efficient sprinkling irrigation method aims to achieve easy installation and detachment and a good sprinkling irrigation effect. A water diversion belt is installed in the direction perpendicular to the planting direction of narrow-row-spacing drilling close planting crops; water conveying pipes are installed on the direction perpendicular to the water diversion belt; the water conveying pipe at the outermost end is folded twice inversely close to the tail end and sleeved with a cutting sleeve to seal a port; micro-spraying hoses are installed in the direction perpendicular to the water conveying pipes, folded twice inversely close to the tail end and sleeved with a cutting sleeve to seal a port; fixing clamps are inserted at the rear portions of the cutting sleeves; the installed water diversion belt and the water conveying pipes serve as the boundary, a farmland is divided into four units A, B, C and D in the direction of extended cross lines formed by the water diversion belt and the water conveying pipes, and the four units are subjected to sprinkling irrigation sequentially; after one-season crops are subjected to sprinkling irrigation, the water diversion belt is removed from the farmland; the micro-spraying hoses are folded in the direction of the water conveying pipes, the pair of folded micro-spraying hoses connected in a four-way mode are tied with a binding rope, and the assemblies are stored on the spot.

Description

technical field [0001] The invention relates to a high-efficiency sprinkler irrigation method with micro-spray belts for drill-sowing densely planted crops with narrow row spacing. Background technique [0002] With the increasing development of science and technology and the increasingly severe water-saving situation, new irrigation methods and irrigation equipment are developing rapidly in the field of water-saving irrigation. These research results have made great contributions to the development of water-saving agriculture in my country. In the field of water-saving sprinkler irrigation, there are currently fixed pipeline sprinkler irrigation, semi-mobile pipeline sprinkler irrigation, central pivot sprinkler irrigation, rolling sprinkler irrigation and micro-spray belt sprinkler irrigation. It has been reported in the literature that compared with flood irrigation on the ground, sprinkler irrigation for field crops can generally save water by 30% to 50%, and increase yi...

Problems solved by technology

However, in actual use, due to the unreasonable planting direction of the micro-spray belt in the field and the planting direction of the narrow-row-spacing and dense-planting crops, the water column sprayed from the micro-spray belt is blocked by the narrow-row-spacing and dense-planting crops, and the sprinkling irrigation is uneven and the sprinkler irrigation effect is poor. On the one hand, although the installation and disassembly of micro-spray belt sprinkler irrigation is not difficult, its installation and disassembly are labor-intensive and time-consuming, and its related components are easily damaged during frequent installation and disassembly
