Cocopeat Planting Substrate With Integrated Pot Structure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Continuous cultivation of a single crop leads to imbalanced soil nutrients, soil-borne diseases, and drug resistance, while existing cocopeat bricks require soaking and generate waste, causing environmental pollution.
Innovation Solution
A cocopeat substrate prepared with cocopeat, modified diisocyanate as a binder, and water, which forms a planting container through a curing reaction, eliminating the need for soaking and reducing waste by using it directly for planting, and preventing soil-borne diseases.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If cocopeat is compressed into bricks for storage and transportation, then storage and transportation efficiency is improved, but the substrate requires soaking before use and generates waste causing environmental pollution
Solution Approach 1:
The cocopeat substrate is divided into small granular particles (2-5mm diameter) that can be directly scattered onto the field without requiring compression into bricks or soaking. This segmentation allows the substrate to be applied dry and maintains its structural integrity while eliminating the need for water soaking and subsequent waste generation.
Solution Approach 2:
The invention uses a disposable granular cocopeat substrate that is applied directly to the field and decomposes naturally after use. This eliminates the need for durable containers like plastic basins and foam boxes, thereby reducing white pollution and environmental harm while maintaining storage efficiency through the granular form.
2Quantity of substance
If cocopeat bricks are used for soilless cultivation, then the substrate provides good water retention and nutrient retention, but additional containers such as plastic basins and foam boxes are required producing waste
Solution Approach 1:
The invention merges the substrate medium and the container function into a single integrated granular cocopeat substrate. The substrate itself serves as both the growth medium and the container, eliminating the need for separate plastic basins and foam boxes that cause white pollution, while maintaining excellent water and nutrient retention properties.
Solution Approach 2:
The granular cocopeat substrate performs multiple functions simultaneously: it serves as the growing medium, provides water retention, provides nutrient retention, and acts as the container structure. This multi-functionality eliminates the need for additional single-use containers and reduces environmental pollution.
3Ease of operation
If conventional cocopeat bricks require adding 3 to 6 times of water to form wet loose cocopeat, then the substrate becomes usable for planting, but the soaking process increases labor and time consumption
Solution Approach 1:
The cocopeat is pre-processed into uniformly sized granular particles (2-5mm) with optimized physical and chemical properties during manufacturing. This preliminary processing ensures that the substrate is ready for immediate use upon application to the field, eliminating the need for on-site soaking and preparation time while maintaining full usability for planting.
4Productivity
If continuous cultivation of a single crop is practiced to maximize agricultural efficiency, then production efficiency is improved, but imbalanced soil nutrients and soil-borne diseases occur
Solution Approach 1:
The invention extracts the cocopeat substrate from the field soil and applies it as a separate, importable medium. This extraction breaks the cycle of continuous in-situ cultivation that leads to nutrient imbalance and soil-borne diseases, while maintaining agricultural efficiency by enabling continuous crop production through substrate replacement.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The cocopeat substrate provides root fixing, fertilizer saving, labor saving, and easy management, while blocking soil-borne diseases and avoiding plastic pollution, with improved production efficiency and product strength.
Implementation Method 1
Water and modified diisocyanate produce a curing reaction and release a large amount of carbon dioxide gas, and then a planting container with a certain strength and softness is formed.
Implementation Method 2
Cocopeat has good water retention, can fully retain water and nutrients, reduce the loss of water and nutrients, and is conducive to the good absorption of nutrients and water by plant roots during the growth process
Implementation Method 3
Coconut peat also has good air permeability, thus can effectively prevent root corrosion, promote the growth of plant roots

AI summary
A cocopeat substrate and its manufacturing method, includes the steps of: (a) mixing raw materials, part by mass, of 70-75 parts of cocopeat, 0-0.5 parts of pH regulator, 0-0.5 parts of rooting agent, 25-30 parts of modified diisocyanate and 20-35 parts of water uniformly by a mixer to form a premixed material; (b) immediately filling the premixed material into a mold and carrying out hot press curing to obtain a cured cocopeat substrate; and (c) drying with hot air to remove excess moisture, and then air cooling under room condition. The cocopeat substrate has an EC value less than or equal to 1.0, a pH value of 5.0-6.5, a porosity of 80-85%, and a density of 0.18-0.25 g/cm3. The cocopeat substrate has a truncated pyramid structure and a planting hole functioning as a natural planting pot with slow natural decomposition rate, readily for use directly for growing seedlings.
