[Double mulching application for Panax notoginseng growing seedlings]
Summary
Double mulching with plastic film and pine leaves significantly improves Panax notoginseng seedling irrigation, reducing water needs and enhancing germination. This method offers better soil moisture and temperature control for optimal growth.
Area of Science:
- Horticulture
- Agronomy
- Soil Science
Background:
- Optimizing irrigation is crucial for Panax notoginseng seedling cultivation.
- Traditional single mulching methods have limitations in conserving soil moisture and temperature.
Purpose of the Study:
- To investigate the effects of different double mulching techniques on Panax notoginseng seedlings.
- To improve irrigation efficiency and seedling quality through enhanced mulching strategies.
Main Methods:
- Field experiments were conducted to assess soil moisture, temperature, and bulk density.
- Germination rate and seedling growth were monitored under various mulching conditions.
Main Results:
- Double mulching (plastic film with pine leaves/straw) reduced irrigation by two-thirds and maintained steady soil moisture (30%) and temperature (9.0-16.6°C).
- This led to earlier, regular, and higher germination rates, improved seedling quality, and resistance to cold snaps.
- Single mulching required more frequent irrigation and resulted in delayed germination and reduced rates, while plastic film alone caused temperature fluctuations and management issues.
Conclusions:
- Double mulching with plastic film and pine leaves initially, followed by single mulching (removing plastic film), is recommended.
- This approach saves water and labor while maximizing germination rate and seedling quality for Panax notoginseng.
