Embodiment 1

[0019] 1. Select Chongming narcissus balls that have grown for two years;

[0020] 2. Castration period: The sowing period of Chongming daffodils is 3-4 days before and after the Cold Dew Festival, and the castration period should be completed 7 days before and after the Cold Dew. However, the castration period is also determined by the length and color of the main bud leaves and the light green and pale green conditions. For example, the leaf buds are green and bulbs grow, which means that the castration period is imminent and must be completed as soon as possible. The color is light green and short, indicating that the castration period can wait a little longer, but at least it should not exceed 6-10 days after the cold dew.

[0021] 3. Preparation of castration tools

[0022] Castration knife iron. It is 15 cm long and 2 cm wide, with a blunt upper end with holes for hanging, an oblate and sharp lower end, and a sword spine in the middle.

[0023] The turnover basket is ...

Embodiment 2

[0037] Through experiments, the inventor conducted variance analysis on the diameter and leaf length / width of the bulbs after castration (see table 1), and the differences in diameter and leaf length / width of the bulbs after castration all reached a significant level of difference . Among them, the difference of bulb diameter and leaf width reached a very significant degree (F values ​​were 18.524 and 13.412, respectively). Statistical analysis of the original data shows (see Table 2) that after castration, the leaf length increased by 10.88%, the bulb diameter increased by 9.71%, and the leaf width decreased by 7.39% compared with the control. The above analysis shows that castration treatment has a significant effect on the leaf length, leaf width and bulb size of narcissus, and the use of castration technology in actual production can effectively increase the bulb size of narcissus and increase the rate of large bulbs.

Abstract

The invention relates to a method for promoting Chongming narcissus to grow more scapes, which comprises the steps of selecting a two-year-old Chongming narcissus bulb and cutting off lateral buds before cultivation in the third year, wherein the cutting-off time is selected to be within a period from seven days before the solar term Cold Dew to ten days after the solar term Cold Dew, the cutting-off part is selected to be at the lower end of a bulb main bud adjacent to the bulb or on the two sides of a flat surface of a bulb main bud leaf, and the cutting-off depth is properly determined on the basis that the lateral buds are cut off but the main bud and the guard strips of the main bud are avoided. By adopting the method and by cutting off the lateral buds of the Chongming narcissus bulb to inhibit nutritional growth, the reproductive growth of the main bud and the flower bud differentiation are promoted, every bulb can be enabled to grow more flowers and more scapes, and the appreciation effect and the commercial value are improved.

Description

technical field [0001] The invention relates to the field of agriculture, in particular to plant and flower propagation technology, in particular to the technology of increasing and promoting flowers of Chongming narcissus, in particular to a method for promoting more scapes of Chongming narcissus. Background technique [0002] Narcissus, a perennial herb belonging to Amaryllidaceae, is native to China and has been cultivated in China for more than a thousand years. It is one of the top ten famous flowers in China and has high ornamental and artistic qualities. "Chongming narcissus" is listed as the three major narcissus in my country together with Zhangzhou narcissus in Fujian and Putuo narcissus in Zhejiang. As a local characteristic flower and characteristic resource in Shanghai, "Chongming narcissus" is the only geographically iconic flower variety resource in Shanghai. It has been cultivated in Chongming County, Shanghai for more than 400 years. As a commercial flower p...
