Description

Technical Field

[0001] The present invention relates to the technical field of controlling Chinese chive maggots, and particularly relates to a compound fertilizer for controlling Chinese chive maggots and its application. Background Art

[0002] Chinese chive (Allium tuberosum Rottler ex Spreng), also known as Chinese chive and jiucai, belongs to the genus Allium of the Liliaceae family and is a perennial herb. The bulbs are clustered, nearly cylindrical; the outer skin of the bulbs is dark yellow to yellowish brown. The leaves are linear, flat, with smooth edges, and the umbel is hemispherical or nearly spherical, and the flowering and fruiting periods are from July to September. Chinese chive is native to southeastern Asia and has been introduced to Belarus, the United Kingdom, Japan and other places, and is now widely cultivated around the world. In China, it is widely cultivated from Heilongjiang in the north to the coastal areas in the east and the Tibetan Plateau in the west. Chinese chive prefers cool and dry conditions, is drought-tolerant, and has strong adaptability to soil. It is a medium-light and long-day plant. Chinese chive is tender, delicious, and has a unique aroma. It is rich in various nutrients and has high edible value. The Chinese chive segments processed from Chinese chive are convenient ingredients for frying and various side dishes. The seeds of Chinese chive can be used as medicine, with the effects of warming and tonifying the liver and kidney, and strengthening yang and astringing essence.
