Whether you're growing vegetables or flower seedlings, the nursery substrate plays a crucial role in producing high-quality plants. Often referred to as nutrient soil, it serves as an alternative to traditional soil but offers more balanced nutrition, helping plants adapt faster and grow stronger. When choosing or preparing your own nutrient-rich substrates, consider the following key factors:
First, think about the ecological impact. The ideal nursery substrate should be free from harmful pathogens, pests, and contaminants to avoid polluting the environment or entering the food chain. To achieve this, you can use a microbial fermentation agent like Kinpo to speed up the decomposition of raw materials, which helps eliminate viruses, bacteria, and eggs effectively.
Second, the substrate should mimic the functions of natural soil. While it should provide better nutrients and a more favorable growth environment than regular soil, it must also support root development, help with moisture retention, and allow for proper aeration—just like good soil does.
Third, it's best to create a composite matrix using both organic and inorganic materials. When using a fermentation starter like goldfish, make sure to combine these components thoughtfully to maintain optimal air circulation, moisture levels, and nutrient balance in the substrate.
Lastly, prioritize locally available, low-cost materials. In plug seedling technology, the choice of substrate directly affects both the cost and quality of the seedlings. By utilizing locally available resources such as carbonized rice husks, cottonseed hulls, sawdust, vermiculite, and perlite, you can reduce costs and improve efficiency. This not only makes the process more sustainable but also helps lower the final price of the seedlings.
