Description

A special fertilizer for oriental lily bulbs

technical field

The invention belongs to the field of oriental lily cultivation, and in particular relates to a special fertilizer for oriental lily bulbs.

Background technique

Lily belongs to Liliaceae Lilium, is a perennial bulb flower, native to my country, Japan, Korea and other places. Lily is not only suitable for potted ornamental, but also suitable for ground planting as cut flowers. The underground bulbs can also be used for food or medicine. It is one of the world's famous flowers. Lily cut flowers are favored by people all over the world for their straight and straight flower stems, emerald green leaves, long flowering period, peculiar flower shape, gorgeous flower color, elegant color, pleasant fragrance and elegant flower posture, and become the mainstream product in the international flower market. The meaning of auspiciousness, unity and happiness of "Hundred Years of Harmony" is more loved by the Chinese people. It has become a high-end flower that has developed rapidly in my country in recent years. The production scale and market consumption are constantly expanding. At present, the main types of flower cultivation are Asian lily hybrids, oriental lily hybrids and musk lily hybrids. The oriental lily is a famous product among lilies, and is now one of the best-selling flowers in the international market.

At present, people have higher and higher requirements for the quality of lily cut flowers. For example, they require long and strong flower branches, many large buds, and many green leaves. The specific shape of lily is reflected in the performance of plant height, bud number, leaf number, and stem thickness. To improve the quality of fresh-cut flowers, cultivation technology is particularly important. In particular, the production of fresh-cut oriental lilies has higher requirements for cultivation technology. The growth cycle of oriental lilies is longer, and there are many factors that affect growth, such as light and fertilizers. The production technology is complex and the flowering period control is difficult. Cultivate lily with existing method and also often appear deformed bud, drop bud, blade scorch etc. unfavorable phenomena, thereby have had a strong impact on the quality of cut flower. Because there are not many high-quality oriental lily cut flowers at present, it is difficult to meet the needs of the market. Therefore, it is of positive and practical significance to study and discuss the cultivation methods of oriental lily with high quality.
