The Six Stages of the Narcissus Growth Process
Today, the editor elaborates on the six stages of the narcissus growth process and introduces the green plant flower cultivation method for understanding the narcissus cultivation method. Next, the editor will introduce it.
Narcissus belongs to the genus Narcissus of the Amaryllidaceae family and is a perennial herbaceous plant. Narcissus prefers warmth but is also quite cold-tolerant. It is not strict about soil requirements, although it enjoys rich fertilizer and sufficient water, it also has the ability to endure barrenness and drought. Once planted, it can survive for several years without being dug up, self-propagate, bloom, and maintain the same plant form. Narcissus is an autumn-planted bulbous plant, and the narcissus planted in the ground begins to grow from autumn. It blooms from March to April of the following year, and the above-ground part gradually withers and enters dormancy in mid-to-late June.
Since narcissus is highly sterile and does not produce seeds, it can only be propagated asexually. The commonly used methods are bulb division and double-scale propagation.
(1) Annual (bud) propagation and cultivation fertilization techniques: Narcissus bulb division is a continuous process that spans several years. Starting from the first division of bulbs, it takes 3 years (actually 4 years) of cultivation to form commercial bulbs. "Bud" refers to the small lateral bulbs, also known as offshoots, which are removed from three-year-old bulbs. It is generally sown in mid-to-late November, using broadcast sowing with a plant spacing of 5 to 6 centimeters. After sowing, cover with 3 to 5 centimeters of soil and mulch with straw. Apply two nitrogen-rich fast-release fertilizers 7 to 10 days after sowing and after the seedlings are full. When furrow irrigation is used, flood the water to 5 to 10 centimeters below the ridge and then drain the furrow water. From the beginning of summer, the above-ground part gradually withers, and by the time of Grain in Ear, the bulbs are harvested, which are two-year-old bulbs, commonly known as "drills," for use in the second year of propagation and cultivation.
(2) Two-year-old (drill) propagation and cultivation fertilization techniques: The bulb shape resembles a drill bit and is commonly known as a "drill head." The cultivation techniques for drills are basically the same as for buds, with only some differences in sowing and management. Prepare the land and make ridges: Open transverse trenches on the ridge surface, with a trench spacing of 30 centimeters, a depth of about 10 centimeters, and a width of 20 to 25 centimeters. When sowing, place the drills with their tops upwards and arrange them on both sides of the transverse trenches, with a spacing of about 10 centimeters. Press the drills slightly into the soil, cover with soil, level the ground, and mulch with straw. The base fertilizer is basically the same as for buds, and after the drills have germinated completely, apply a top dressing once with human manure and fast-release nitrogen. Apply 750 kilograms of human manure and 0.5 to 1 kilograms of urea per mu; apply another top dressing at the end of January or early February of the following year; after the Spring Equinox, apply a phosphorus and potassium fertilizer once to promote bulb expansion.
(3) Three-year-old (seedling) propagation and cultivation fertilization techniques: Seedlings are the commercial bulb (flower head) of Chinese narcissus in the final year of cultivation. The quality of the seedlings is crucial for cultivating commercial bulbs. Before planting, it is essential to strictly select and specially treat the seedlings—castration. The seedlings must be free of diseases and pests, remove the small and inferior ones. The criteria for good seedlings are: bulbs with proper shape, uniform size, and circumference of about 15 centimeters; bulb bases that are small and solid, with two circles of root points; skin membranes that are golden yellow and glossy, without "leakage" (no root points due to disease damage at the base) and no damage. Remove the lateral bulbs (buds) next to the seedlings, and disinfect the wounds with a 40% formalin solution diluted 120 times.
The above introduction to the six stages of the narcissus growth process and the method of understanding narcissus flower cultivation can be used as a reference suggestion for everyone.
