Embodiment 1

[0030] A cultivation method for improving the quality of daffodil bulbs, comprising the following steps:

[0031] 1) Carry out soil preparation and furrowing according to conventional methods;

[0032] 2) bulb selection: select 2-year-old healthy bulbs with a diameter of 6-8cm, and perform bulb castration and disinfection according to conventional methods;

[0033] 3) Sowing: excavate a planting ditch with a depth of 15-20cm, the row spacing (ditch spacing) is 40±2cm, the plant spacing is 25±2cm, and the planting density is 5000±200 grains / mu. When sowing, the bulbs in the same row are castrated Wounds facing each other (eg figure 1 shown);

[0034] 4) Mid-term growth regulation: Spray the mid-term growth regulation solution once in the first ten days of February and the first ten days of March respectively. The components of the mid-term growth regulation solution and their mass percentages in the mid-term growth regulation solution are as follows:

Embodiment 2

[0043] A cultivation method for improving the quality of daffodil bulbs, comprising the following steps:

[0044] 1) Carry out soil preparation and furrowing according to conventional methods;

[0045] 2) bulb selection: select 2-year-old healthy bulbs with a diameter of 6-8cm, and perform bulb castration and disinfection according to conventional methods;

Abstract

The invention belongs to the technical field of narcissus cultivation, and particularly relates to a cultivation method capable of improving the quality of narcissus bulbs. By changing the seeding mode in cooperation with the adoption of the growth regulation technology, the relation between the number of narcissus bulbs per unit area and the circumference diameter of main bulbs, the growth condition of lateral bulbs and the apparent bulb shape is effectively coordinated, and thus the purposes of high quality and high efficiency are achieved. By means of the method, the defects that in current production, narcissus grows vigorously in the earlier stage, the plant gets fatigued and weak in the middle stage, leaves are presenile in the later stage, and harvested bulbs are not plump are overcome, the stress resistance of narcissus plants can be improved, the withering of narcissus plants can be delayed, the growing period can be prolonged, the nutrient accumulation of bulbs is facilitated, and the proportion of special-grade and first-grade bulbs can be effectively increased.

Description

technical field [0001] The invention relates to the technical field of daffodil cultivation, in particular to a cultivation method for improving the quality of daffodil bulbs. Background technique [0002] Narcissus is one of the traditional famous flowers in China. It has been cultivated in Zhangzhou for more than 500 years. Over the years, Zhangzhou's production of narcissus commercial balls has accounted for more than 90% of the country's total. Narcissus commercial bulbs are 3-year-old bulbs planted through buds, diamonds, and seedlings. The quality grades are mainly determined by the diameter of the main bulb, the growth of the side bulbs, and the appearance of the spherical shape. Among them, the super grade is the main bulb. Circumference diameter ≥ 25.5cm, excellent plumpness, ≥ 6 flowering branches per flower, no pests and diseases, two pairs of side bulbs complete, beautiful spherical shape; first-grade main bulb diameter ≥ 24cm, excellent fullness, ≥ 5 flowering b...
