PHA is a biodegradable polymer naturally produced by microorganisms through fermentation process. PHA slow-release fertilizers are made by encapsulating nutrients in small balls or granules made of PHA to achieve the effect of slow-release, so as to achieve the purpose of improving the utilization rate of fertilizers and reducing the environmental pollution.
Features
- Long-lasting: Due to its special structural design, PHA slow-release fertilizers can continuously provide crops with essential nutrients over a long period of time.
- Environmentally friendly: as one of the bio-based materials, PHA itself has good biodegradability, and can be decomposed by microorganisms in nature after completing its mission, without causing soil pollution.
- Water-saving and energy-saving: Compared with traditional fertilization methods, the use of PHA slow-release fertilizers can effectively reduce the number of times and the amount of water used for irrigation, and also save the human resources required in the application process.
- Promote healthy growth of plants: The rate of nutrient release is reasonably controlled, avoiding problems such as root burning caused by over-fertilizing, which helps plants grow healthily.
Applications
- Agriculture
- In vegetable cultivation, by adjusting the proportion and type of PHA slow-release fertilizer, it can meet the nutrient demand of different vegetable varieties during the whole growth cycle.
- For fruit trees, PHA slow-release fertilizers can better match the characteristics of their long growing period, ensuring the quality of fruits and reducing labor intensity.
- Horticultural greening
- In urban gardening, the use of PHA slow-release fertilizer not only helps to improve the survival rate of plants and trees, but also significantly reduces the cost of maintenance.
- Home gardening enthusiasts can also choose PHA slow-release fertilizers suitable for small potted plants to enjoy the fun of green life.
- Ecological restoration
- When restoring the vegetation in some seriously polluted areas, the use of PHA slow-release fertilizers can help the new plants to take root quickly and gradually improve the quality of the local ecological environment.
