Solution Overview

Problem

Existing strip-till plant cultivation methods face challenges such as limited flexibility in soil compaction and fertilizer placement, which can lead to uneven germination, increased pest occurrence, and environmental contamination, as well as restrictions on simultaneous cultivation of plants with different requirements.

Innovation Solution

The method involves scarifying soil strips to 35 cm, leaving non-cultivated strips between, and using a machine equipped with disc coulters, fertilizer dosing, pressing wheels, and compacting wheels to precisely place mineral fertilizers and seeds, allowing for individualized soil compaction and fertilizer application, and controlling mulch distribution to optimize soil conditions and reduce clogging.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If strip-till cultivation is used with deep scarification to 35 cm, then soil uniformity and germination conditions are improved, but flexibility in soil compaction and fertilizer placement is limited

Engineering Contradiction:

Improvesoil uniformityVSAvoidflexibility in compaction and fertilizer placement

Core Design Contradiction:

Manufacturing precisionVSAdaptability or versatility

Solution Approach 1:

The cultivated strip is divided into multiple sub-strips (first cultivated strip, second cultivated strip, third cultivated strip) with different scarification depths and compaction characteristics. This segmentation allows each sub-strip to be optimized for specific plant requirements while maintaining overall soil uniformity in the cultivated area.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Different regions within the cultivated strip are given different properties: the first cultivated strip has deeper scarification for certain plants, the second has intermediate scarification, and the third has shallower scarification. This local differentiation provides flexibility in compaction and fertilizer placement while maintaining soil uniformity where needed.

Inventive Principle:

Principle #3Local quality

2Quantity of substance

If mineral fertilizers are placed deeply in scarified strips, then fertilizer use efficiency is improved, but environmental contamination risk increases

Engineering Contradiction:

Improvefertilizer use efficiencyVSAvoidenvironmental contamination

Core Design Contradiction:

Quantity of substanceVSObject-affected harmful factors

Solution Approach 1:

Fertilizer placement is localized to specific sub-strips based on plant requirements. The first cultivated strip receives deep fertilizer placement for high-efficiency nutrient uptake, while the second and third strips receive shallower placement to reduce environmental contamination risk. This local differentiation optimizes both fertilizer efficiency and environmental safety.

Inventive Principle:

Principle #3Local quality

3Reliability

If mulch is removed and left on non-cultivated strips, then water infiltration is improved, but clogging of operating elements increases

Engineering Contradiction:

Improvewater infiltrationVSAvoidclogging of operating elements

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The field is segmented into cultivated strips and non-cultivated strips with different mulch management. Mulch is removed from cultivated strips to prevent clogging of operating elements during scarification and sowing, while mulch is retained on non-cultivated strips to maintain water infiltration. This spatial segmentation resolves the contradiction between water infiltration and operational ease.

Inventive Principle:

Principle #1Segmentation

4Manufacturing precision

If traditional plough cultivation is used, then soil preparation is thorough, but productivity is reduced under unfavourable soil conditions

Engineering Contradiction:

Improvesoil preparation qualityVSAvoidcultivation speed

Core Design Contradiction:

Manufacturing precisionVSProductivity

Solution Approach 1:

The traditional plough mechanical system is replaced with a strip-till system that uses localized scarification tools (disc coulters, scarifying teeth) to create cultivation strips. This substitution maintains thorough soil preparation quality in the cultivated areas while dramatically increasing productivity by leaving non-cultivated strips that require no processing.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

AI summary

The subject of the invention is a plants cultivation method, wherein cultivated strips (1) of soil, where crop seeds are to be sown, are scarified down to 35 cm, wherein non- cultivated strips (3) are left between these strips (1), wherein along one passage of a machine equipped with a disc coulter, scarifying teeth, a fertilizer dosing device, pressing wheels, seeds sowing coulters (13), and depth and compacting wheels (9), mulch is removed and left on non-cultivated strips (3), the soil is scarified within cultivated strips (1), after soil scarification, mineral fertilizers are placed within the scarified cultivated strips (1), then the cultivated strips (1) are compacted using a pressing wheel of the machine, and after compaction, crop seeds are sown therein, and then the soil is compacted using the depth and compacting wheel (9) of the machine, maintaining the depth of the sowing and water infiltration. The method is characterized by the cultivated strip (1) being divided into cultivated flows (2) and fertilizer flows (4) wherein the mineral fertilizer is applied using the scarifying tooth of the machine.
