Narcissus soilless cultivation method

Abstract

The invention discloses a narcissus soilless cultivation method. The method includes the following steps of (1), preparation of organic substrates; (2), selection of seeds; (3), castration of the seeds; (4), planting management, wherein the substrates are flatly laid on a planting bed adopting a net-shaped carrier for bearing the substrates, then the seeds are sowed on the substrate layer, watering is conducted immediately after the seeds are sowed, and the substrate layer is covered with straw; (4), water and fertilizer management, wherein watering is performed once or twice each day at the seedling emergence stage and the sprouting stage, watering is performed every one or two days at the withering stage, spraying of biogas slurry is performed every five to seven days, and organic microelements are added to the biogas slurry; and (5) harvesting, wherein after narcissus leaf blades wither, the bulbus of narcissus can be harvested when the substrate layer tends to be cracked. According to the narcissus soilless cultivation method, organic matter serves as the main material, soilless cultivation is performed on the narcissus, a suitable growth environment is provided for the narcissus, the narcissus is made to grow robustly in combination with a water and fertilizer drop irrigation management method, the harvesting cycle is shortened, the yield is raised, and quality is guaranteed.

AI Technical Summary

Benefits of technology

This patented innovative technique described in this patent allows for efficient greenhouse growing without harmful chemical agents like sulfur or selenium. By combining these ingredients into a single unit called biofilm, there will become more effective at promoting root health and increasing yields compared to conventional methods. Additionally, the inventors found that adding specific metals helps reduce disease resistance and enhance crops' ability to absorb essential mineral nutrition from plants. Overall, this novel approach simplifies farming operations while maintaining environmental benefits over existing techniques.

Problems solved by technology

This patented describes different ways to improve the efficiency and productivity of growing plants under various conditions like light or heat stress without causing damage on their leaves. Additionally, there exists a challenge where excess amounts of nitrogen can harm both wildlife health and food safety when treating these types of cropping systems due to lack of adequacy of germination environments during hydrometamide immersion culturing processes. To address this issue, the inventors propose using biochar solutions instead of traditional soil cultivations while maintaining strong root system strength against attackers' attacks.
