Twin Row Subirrigation With Underground Drip Hoses
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing subirrigation methods are ineffective for twin row growing and no-till sowing techniques, as they fail to optimize irrigation water management, fertilizer distribution, and soil drainage, particularly in herbaceous crops and un-tilled land with residues, leading to inefficiencies and environmental issues.
Innovation Solution
A twin row growing method with subirrigation that involves arranging drip hoses underground, memorizing their position, sowing seeds in twin rows aligned with hose axes, and controlling water distribution to avoid land saturation, allowing for efficient irrigation and fertilizer delivery directly to roots while maintaining soil porosity and reducing labor and energy costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If drip hoses are arranged between rows of plants in beds with heavy ground working, then subirrigation can be implemented, but the method is not suitable for no-till sowing and requires frequent ground intervention
Solution Approach 1:
The drip hoses are arranged in the ground before sowing takes place, creating a permanent irrigation infrastructure that eliminates the need for ground working during the growing season. This preliminary arrangement allows no-till sowing while maintaining effective subirrigation capability.
Solution Approach 2:
The irrigation system is segmented into individual drip hoses positioned at regular intervals, with each hose serving a specific row of plants. This segmentation allows flexible configuration that adapts to no-till conditions while maintaining effective water delivery to root zones.
2Quantity of substance
If water is supplied to all land between hoses, then complete irrigation coverage is achieved, but soil saturation occurs and drainage capacity is lost
Solution Approach 1:
Irrigation water is delivered locally to the root zones of plants through subsurface drip hoses, rather than uniformly across all land between hoses. This localized water application ensures complete irrigation coverage for plants while preventing soil saturation in inter-row areas, maintaining drainage capacity.
Solution Approach 2:
The drip hoses act as intermediaries that deliver water directly to the root zones through subsurface placement. This intermediary system enables precise water control, providing irrigation where needed while preventing harmful saturation in other areas.
3Productivity
If twin row sowing is implemented with conventional irrigation, then crop density is increased, but irrigation water management becomes inefficient and fertilizer distribution is optimized
Solution Approach 1:
The irrigation system is segmented into individual drip hoses positioned between twin rows, with each hose serving a specific row. This segmentation enables independent water management for each row, optimizing irrigation efficiency while supporting increased crop density through twin row sowing.
Solution Approach 2:
Conventional mechanical irrigation methods are replaced with subsurface drip irrigation, eliminating the need for complex water management infrastructure. The drip hoses deliver water directly to root zones through subsurface placement, improving irrigation efficiency while supporting twin row sowing configurations.
4Reliability
If ground is tilled or plant residues are removed before sowing, then proper seedbed preparation is achieved, but labor and energy costs increase
Solution Approach 1:
The drip hoses are arranged in the ground before sowing, creating a permanent irrigation infrastructure that eliminates the need for ground working during the growing season. This preliminary arrangement enables no-till sowing, maintaining seedbed preparation quality while dramatically reducing labor and energy costs.
Solution Approach 2:
The subsurface drip irrigation system serves itself by being permanently installed in the ground, eliminating the need for repeated ground intervention. The system maintains its functionality through self-service operation, allowing no-till sowing and residue retention while preserving irrigation effectiveness.

Function Achieved in This Case
This method ensures optimal water and fertilizer use, reduces waste and pollution, promotes sustainable agriculture, limits weed growth, and allows for successive crops without tilling, while maintaining soil health and reducing energy consumption.
Implementation Method 1
subirrigation generally means an irrigation method in which the water is supplied to the crops through parallel drip hoses, placed at regular intervals in the ground at a certain depth, so as to remain underneath the root system of the plant grown
Implementation Method 2
detecting the moisture of the soil at various depths and at various distances from the single hoses during the introduction of water into said hoses

AI summary
Twin row growing method with subirrigation, comprising the steps of: - arranging stably before sowing, underneath a flat agricultural land (1), parallel to one another and at regular intervals, at a specific depth (h), a plurality of drip hoses (2) for the underground distribution of water; - memorizing in time the position of said drip hoses; - identifying in time the position of said previously arranged hoses (2); - sowing seeds (3) in twin rows (B) composed of parallel rows in said flat agricultural land (1), at a lesser depth than said specific depth (h), so that the centreline of each twin row (B) coincides with the axis of each single hose (2), and so as to leave a desired distance (D) between external rows of seeds (3) of adjacent twin rows; - introducing water into said drip hoses (2), so that the water distributed by means of subirrigation reaches the roots (4) of plants (5) born from said seeds (3) belonging to each twin row (B), leaving a strip (d) of agricultural land, of a lesser width than said desired distance (D) between said hoses without irrigation water.
